Law Enforcement on Fishery: Prohibition of Trawl Nets as an Effort to Protect Small Fisherman Fairly

The sea and its resources, especially fishery resources, are a gift from God Almighty for the welfare of all Indonesian people. Based on the state's right to control the earth and the natural resources contained therein, which originates from Article 33 paragraph (3) of the 1945 Constitution of the Republic of Indonesia, the government must regulate fishery resources for the greatest prosperity of all people. The use of fishery resources is carried out with various legal products ranging from laws, government regulations, and presidential decrees to ministerial rules. Regulations on using fishery resources include prohibiting using trawl nets to catch fish in certain waters. This prohibition aims to prevent damage to the marine environment, ensure the sustainability of fishery resources, and protect small fishermen. However, in its implementation, it is still hampered by the problem of law enforcement, which is hindered by disharmony of regulations, the availability of professional law enforcement officers, and the lack of support for facilities and infrastructure considering the vast area of law enforcement. One thing that is no less important in enforcing the law on the prohibition of the use of trawl nets is the low legal awareness of fishing communities, especially industrial fishermen who only care about themselves without paying attention to the preservation of marine ecosystems, the sustainability of fishery resources, and the protection of small fishermen or traditional fishermen.

Global Marine Ranching Research: Progress and Trends through Bibliometric Analysis

With the increasing prominence of pollution issues in offshore waters, marine ranching plays a crucial role in restoring marine ecosystems and ensuring the sustainable use of fishery resources. This paper provides a comprehensive bibliometric analysis of global marine ranching research. The study indicates that policy is the primary driver of the industry's development. It also reveals that the low level of interconnectivity between China and other major developing countries, as well as cooperation between governmental and research institutions in the area of marine ranching. In light of these considerations, prospective strategies for the future evolution of marine ranching can be formulated with a view to optimising and enhancing the seedling production system, and to forecasting changes in marine ranching in conjunction with the application of modern computing techniques and the field of remote sensing.

Understanding Local Perspectives on Climate Change and Its Impacts on Small-Scale Fishing Communities in Honda Bay, Palawan, Philippines

Climate change's adverse impacts are already evident, particularly in coastal areas. However, local perception that is essential in formulating policies for mitigating its impacts remains limited. Thus, this study evaluated the level of perception of small fishing communities on climate change and its impacts on livelihood and the environment. The data were obtained using a face-to-face survey with the aid of a structured questionnaire. They were interpreted and analyzed using the Likert point scale, descriptive statistics, and chi-square. A total of 308 male fisherfolks participated in the survey. Majority belong to age 51-60 years old (38%) and 61 years old and above (32%). Most of them (65%) finished elementary and generally (94%) rely on fishing for main source of living. As for income, 47% earned an estimated monthly income of Php 2,501-5,000 and 28% got Php 5,001-7,500. Most of the respondents are full-time fishers (89%) for more than 11 years (87%), and fishing within the municipal water (92%). Majority (90%) have an idea about climate change as reflected by their very high score in Likert Perception (24.3±2.3%). The climate change impacts perceived by the respondents include: increasing sea surface temperature (87%); fish are sensitive to changing climate (87%); and fossil fuel consumption contributes to climate change (84%). They said they got the information from TV/ Radio (99%) and social media (10%). The age (p-value < 0.0032) and source of information (p-value < 0.0348) are among the variables with significant relationship to the perception of respondents on climate change impacts. In total, it appears that majority of fishers are aware of the impacts of climates. It is suggested that effective management actions, such as emergency preparedness schemes and livelihood diversification should be explored to address the specific needs of fishing communities that are vulnerable to the impacts of climate change. Furthermore, an ecosystem-based approach that focuses on socio-economic dynamics and climate-induced changes in assessments and management is essential for the sustainable use of fisheries resources amidst the changing climate.

Sustainable Development Perspective: Analysis of Capture Fisheries in Muncar District Banyuwangi

Capture fisheries resources in Muncar Regency have enormous potential to support the lives of the community, especially fishermen. However, in these conditions, the volume of capture fisheries production in Muncar Regency has decreased. This research aims to direct sustainable development efforts in the capture fisheries subsector so that it can improve the welfare of fishermen. This is done by optimizing the use of fishery resources without ignoring economic, ecological (environmental), and social aspects. This research uses descriptive analysis methods. The results of measuring the level of sustainability of capture fisheries resources in Muncar District show that the average value is still low. From each dimension (economic, social, and environmental) several criteria have medium (M) and high (H) scores. This means that each dimension requires alternative recommendations to support sustainable capture fisheries development. It takes synergy from all levels of society to maintain the balance of the marine ecosystem. Increasing awareness of coastal communities is needed to maintain the balance of the capture fisheries resource ecosystem. Apart from that improving the quality of human resources in fishing communities is an important thing that the government can do to support the sustainable development of capture fisheries resources.

Bottom fishery impact generates tracer peaks easily confused with bioturbation traces in marine sediments

Abstract. In the process of reworking sediments and thus shaping biogeochemical processes, marine bottom-dwelling animals are thought to play a pivotal role in many benthic environments. Bioturbation (particle reworking) includes the downward transport of particles into the sediment as a major process and is sometimes detected as subsurface maxima (peaks) of specific particulate substances (tracers). Here, we document the fact that subsurface peaks, such as those typically attributed to biological particle transport in sediments, may equally be generated by otter boards in bottom-trawling fishery. Boards can generate tracer peaks whereby they scoop sediment from the surface, flip it over, and deposit it onto the adjacent seafloor. These peaks are indistinguishable from those generated by benthic fauna burying surface material at sediment depth. We demonstrate this for the particle tracer chlorophyll a in silty sand from the western Baltic Sea with fauna that generally do not burrow deep in a global comparison. Our inability to distinguish the driving processes generating the peaks indicates limits to our understanding of the magnitude and spatial extent of bioturbation traces in this environment. It also poses a problem for the assessment of fishery resource use and benthic processes. However, based on natural fauna abundance, behavioral information, and fishery intensity data, we identify macrofauna and not otter boards as the dominant cause of peaks at the sites investigated here.

The Long-Term Dynamics of Walleye Pollock Stocks in Relation to Oceanographic Changes in the East Sea

The decline in walleye pollock (Gadus chalcogrammus) stocks in Korean waters is a major concern for fishery conservation and management. However, the causes and mechanisms of this collapse remain unclear. This study investigated the complex dynamics influencing the abundance of walleye pollocks in the East Sea of Korea over several decades, by analyzing data from long-term changes in biological factors including composition of length and sex, catch, and oceanographic condition. Prior to the mid-1980s, the catch ratio of juveniles was higher than that of adults, with a higher proportion of females in both juvenile and adult catches compared to males. Especially, high fishing pressure on female individuals can be an important factor contributing to declining reproduction. Consequently, after the mid-1980s, there was a sudden decline in juvenile pollock catches. In the late 1980s, there was a rapid increase in sea surface temperature (SST) in the spawning grounds, resulting in a decrease in both the duration of suitable temperature for spawning and the regional proportion for suitable spawning conditions. Consequently, the decline in pollock stocks after the late 1980s due to overfishing of pollock in the mid-1980s was further exacerbated by the effects of SST warming after the late 1980s. These findings highlight the impact of overfishing and environmental factors on pollock stocks and indicate the need for appropriate fishery management practices to ensure the sustainable use of fishery resources.

Food web structure and trophic diversity for the fishes of four islands in the Pearl River Estuary, China

The Wanshan Archipelago, situated in the Pearl River Estuary, stood as a key fishing ground in China, boasting abundant fishery resources. To investigate variations in trophic niches and food sources among different islands within the Wanshan Archipelago, and to advance research on fish food webs and energy flow in the Pearl River Estuary, this study conducted a survey of fish communities in nearshore islands (Guishan Island, Dongao Island) and offshore islands (Wailingding Island, Wanshan Island) using triple gill nets during the autumn of 2021. The trophic niche characteristics of fishery organisms in these islands were analyzed utilizing carbon and nitrogen stable isotope technology. The results indicated that trophic niche width and biodiversity of fish communities in the nearshore islands surpassed those in the offshore islands, and the food chain length exhibited a trend of Guishan Island (4.04) > Dongao Island (3.98) > Wanshan Island (3.91) > Wailingding Island (3.86). The trophic niche indexes (CR, NR, CD, and SEAc) of fish communities in nearshore islands were higher compared to those on offshore islands, while MNND and SDNND suggested that fish communities in offshore islands were at a lower trophic level. Zooplankton emerged as the primary food source for fishery organisms in the Wanshan Archipelago. Feeding rates on zooplankton were 68.8 % and 70.4 % in Guishan Island and Dongao Island, and 53.7 % and 58.0 % in Wailingding Island and Wanshan Island, respectively. The proportion of benthic organisms fed near offshore islands was higher than nearshore islands. This study speculated that the fish in nearshore islands may shift from zooplankton food chain to benthic food chain. In addition, this study compared the trophic niche differences among the four islands in the Pearl River Estuary, clarified the diversity of feeding sources and trophic structure within fish communities, and revealed significant distinctions in fish food webs between the islands inside and outside the Pearl River Estuary. It will provide new information on the trophic interactions of fish in the Pearl River Estuary, and help to promote the ecological development and sustainable use of fishery resources.

Fishery and conservation implications of molecular characterization and traceability of ceviche samples from Pacific Panama

Genetic analysis of 111 samples from ceviche cocktails and fish fillets used for ceviche, obtained from fish markets and processing plants in the Pacific zone of Panama were conducted to determine species composition, trace origin (native, nonnative or imported frozen species) and CITES species status. A total of 21 species were detected (20 fishes and one invertebrate): Coryphaena hippurus (dolphin fish), Pangasianodon hypophthalmus (basa), Trachinotus falcatus (pompano), Cyclopsetta querna (toothed flounder), Atheresthes stomias (arrow-tooth flounder), Lobotes pacificus (Pacific tripletail), Bagre panamensis (Chihuil sea-catfish), B. bagre (Coco sea-catfish), Ariopsis seemanni (Tete sea-catfish), Aspistor luniscutis (yellow sea-catfish), Centropomus viridis (white snook), C. undecimalis (Union snook), Sphyrae naensis (Mexican barracuda), Oreochromis niloticus (Nile tilapia), O. mossambicus (Mozambique tilapia), Cynoscion praedatorius (Boccone weakfish), Protonibea diacanthus (blackspotted croaker), Gadus chalcogrammus (Alaska pollock), Sphyrna lewini (scalloped hammerhead shark), Makaira nigricans (blue marlin) and Dosidicus gigas (giant Humbolt squid). Native species found in ceviche samples were reduced in numbers compared with imported and cultivated ones. Thus, the most common detected fish species was basa, followed by the Nile tilapia and the dolphin fish. This is a positive result in terms of sustainability of local fisheries, since basa is imported as frozen fish meat from Asia. The same applies for Nile tilapia, a cultivated freshwater species not captured from local fisheries. For the dolphin fish, despite being common and exploited in Pacific waters, previous studies suggest its fishery is sustainable in Panama waters. In terms of conservation status, one species cataloged by IUCN as vulnerable (VU), the blue marlin (M. nigricans) and one as critically endangered (CR), the scalloped hammerhead shark (S. lewini) were detected. Sphyrae lewini is also catalog as CITES appendix II. The giant Humbolt squid (D. gigas), classified by IUCN as data deficient (DD), was the only invertebrate detected in samples obtained from a ceviche processing plant. Two sets of primers and dual labeled probes were designed for qPCR eDNA detection of the only CITES species, S. lewini. These represent the first qPCR markers for eDNA detection of S. lewini. Results from this project promote the sustainable use of fishery resources and might provide ceviche producers with a certificate from MarViva Foundation certifying that their ceviche is free of sharks or species threatened/protected by law, giving added value to their product. Molecular detection and molecular traceability are sensitive and species specific, what makes of this tool a reliable method to combat IUU (illegal, unreported and undocumented) fishing.

Tinjauan Hukum Pidana Internasional Atas Tindakan Eksploitasi Sumber Daya Perikanan Di Wilayah Laut ZEE Indonesia Oleh Kapal Asing

The Exclusive Economic Zone (EEZ) is a new legal system regulated in the 1982 maritime law agreement between countries. Therefore, the abundant marine fisheries resources in Indonesia's EEZ allow for actions that are detrimental to being an archipelagic country due to violations committed by foreign countries that violate state sovereignty. Therefore, the Indonesian government has established legal rules regarding the use of fisheries resources and maritime boundaries in Law Number 17 of 1985 from the ratification of UNCLOS 82, and in its implementation these legal rules must not deviate from the Indonesian Constitution. Apart from vigilance, of course this is a a warning to the country in maintaining its sovereignty so that it is protected from intervention by foreign countries who secretly steal data on the country's territory and look for gaps in defense weaknesses through maritime boundaries. Therefore, all regulations regarding the territorial boundaries of the Exclusive Economic Zone (EEZ) have been summarized in UNCLOS 82. This article aims to explore aspects related to the protection of water resources in the EEZ and the provisions of international and transnational criminal law that anticipate the protection of water resources in the EEZ. This research utilizes normative methods that are descriptive in nature and tend to utilize data analysis.

Assessment of Seabream Fisheries Stock of Oman Using the Monte Carlo Catch Maximum Sustainable Yield and the Bayesian Schaefer Model Methods

The establishment of managerial approaches for the sustainable use of fishery resources depends on a critical understanding of the stock status. The Monte Carlo catch maximum sustainable yield (CMSY) method and a Bayesian state–space implementation of the Schaefer model (BSM) are recent, but widely used, stock assessment methods for data-limited situations. Here, CMSY and BSM were used to evaluate the state and exploitation level of the seabream population. Collections of catch and effort data from 1988 to 2021, pertaining to time series, were obtained from the Fishery Statistics Book published by the Ministry of Agriculture, Fisheries and Water Resources of Oman. The CMSY and BSM results were similar, indicating that the seabream stock of Oman was overfished, as B/BMSY = 0.96 (<1) and F/FMSY = 1.25 (>1). The probability that the stock was being overfished and undergoing overfishing in 2021 was 53%, while the probability that the stock was healthy (high biomass and low fishing pressure) was only 16.2%, when the target should be higher than 75%. The conclusions are of a preliminary nature owing to the utilization of comparatively new methodologies employed to generate them, which commonly validate the condition and utilization of the populations under investigation. Our research suggests that the seabream population in Oman is overfished, and reducing fishing activity is necessary to restore its abundance.

Long-term trends in functional diversity of exploited marine fish in the Azores’ archipelago: past and present

IntroductionEffective fisheries management requires monitoring and quantifying changes in exploited fish communities. Concerns about global fisheries sustainability have led to innovative approaches. Functional diversity, rooted in ecological theory, offers valuable insights into fishery activities and ecosystem processes. A trait-based approach was used to investigate the functional diversity of landed fish species in the Azores archipelago from 1980 to 2021.MethodsLandings data of exploited Actinopterygii and Elasmobranchii were provided by the Azores Fisheries Auction Services (LOTAÇOR/OKEANOS-UAc Fisheries Database). A trait matrix was built, incorporating 12 functional traits assigned to each species, capturing their importance in marine ecological processes. The Quickhull algorithm for convex hull was employed to calculate the volume occupied by the species in the four-dimensional functional space. Functional diversity (FD) was measured using three indices: functional richness (FRic), functional evenness (FEve), and functional divergence (FDiv). Trends in FD indices over the past 42 years were visualized using Generalized Additive Models (GAM) with interaction terms.Results and discussionGAM analysis revealed significant variations in the functional space and FD metrics over time. FRic exhibited peaks in the 1980s and 2010s, declining in the 1990s and from the 2010s onwards, indicating diversification in target species. The recent decrease in FRic can be attributed to the absence of catches of species with unique traits. The distribution of landings and trait combinations showed higher regularity in the functional space during the 1980s and 1990s (high FEve). Actinopterygii species targeted in the 1980s and 1990s had lower trait divergence (low FDiv) compared to those targeted from the 2000s onwards (high FDiv). Variability in FD can be linked to changes in fishing practices, species availability, market demand, environmental factors, and local regulations. This study underscores the importance of considering FD metrics alongside species richness and abundance when assessing the potential effects of fisheries on marine ecosystems and sustainable use of fishery resources.

Polyunsaturated Fatty Acids from Eel Extract Attenuate Gastritis and Hepatotoxic by Indomethacin-Induced in Rats

Nonsteroidal anti-inflammatory drugs (NSAIDs) potentially induce hepatotoxicity and ulcerative lesions in the stomach. Several studies have been conducted on the benefits of natural resources to overcome the problem of drug side effects. However, the use of fishery resources, such as the eel (Anguilla bicolor), for medicine has not been widely studied. Eels are rich in omega-3 polyunsaturated fatty acids with antioxidant and anti-inflammatory effects. Therefore, this study aims to determine the gastroprotective and hepatoprotective effects of polyunsaturated fatty acids extracted from eel (FaE). The experimental models were 42 male rats divided into seven groups. The experiment was performed for 14 days by orally administering FaE samples. On the 15th day, the rats were orally induced with indomethacin (48 mg/kg). After 8 h of induction, they were euthanized using ketamine and xylazine. Furthermore, blood samples were collected from the animals to measure the levels of aspartate aminotransferase and alanine aminotransferase. Malondialdehyde (MDA) and glutathione (GSH) levels were measured, while the histology of the liver and stomach were examined. The results showed that the administration of FaE from a dose of 1000 mg/kg significantly attenuated the liver and stomach damage caused by indomethacin. The influence of oxidative stress inhibition on damage is characterized by inhibition of the increase in MDA and a decrease in GSH. This research shows that FaE has the potential to inhibit liver and gastric damage due to the use of NSAIDs. However, further investigation needs to be conducted on other specific parameters of the inflammatory mechanism.

Monitoring of multiple fish species by quantitative environmental DNA metabarcoding surveys over two summer seasons.

Periodic monitoring can provide important information for the protection of endangered fish, sustainable use of fishery resources and management of alien species. Previous studies have attempted to monitor fish using non-invasive environmental DNA (eDNA) technology, generally employing quantitative PCR to quantify the eDNA concentration. However, the throughput was limited. High-throughput metabarcoding technology can detect the DNA of multiple species simultaneously in a single experiment but does not provide sufficient quantification. In this study, we applied a quantitative metabarcoding approach to simultaneously quantify the eDNA concentration of an entire fish assemblage in a small reservoir over two summer seasons. Traditional surveys were also conducted to investigate the individuals of fish. The eDNA concentrations were quantified using quantitative metabarcoding, and the fish species detected using this approach were highly consistent with the results of traditional fish monitoring. A significant positive relationship was observed between the eDNA concentration and fish species abundance. Seasonal changes in fish community structure were estimated using eDNA concentrations, which may reveal the activity seasons of different fish. The eDNA concentrations of different fish species peaked at different water temperatures, reflecting the differential responses of fish species to this environmental factor. Finally, by detecting outlier eDNA concentrations, the spawning activities of 13 fish species were estimated, 12 of which were roughly consistent with the current knowledge of fish spawning periods. These results indicate that quantitative eDNA metabarcoding with dozens of sampling times is useful for the simultaneous ecological monitoring of multiple fish species.

Spatial and Temporal Variations in Autumn Fish Assemblages in the Offshore Waters of the Yangtze Estuary

The offshore waters of the Yangtze Estuary are an important fish habitat, and the large gradient of environmental conditions leads to different fish assemblages. We studied the spatial and temporal variations in fish assemblages and their relationships with environmental factors in the offshore waters of the Yangtze Estuary during the autumns of 2012–2016. The fish assemblage consisted of 64 fish species from 39 families, of which 6 species were dominant. There were significant interannual differences in fish abundance, biomass, and species composition, with the highest abundance and biomass in 2013, the lowest abundance in 2016, and the lowest biomass in 2015. Redundancy analysis revealed that total suspended particles and dissolved oxygen drove interannual variation in fish abundance, biomass, and species composition, and depth drove spatial variation in the fish assemblage. According to the depth, the fish were classified as shallow assemblage and deep assemblage. Understanding the spatial and temporal patterns of fish assemblage in the offshore waters of the Yangtze Estuary is beneficial to the conservation of fish and the sustainable use of fishery resources in the offshore waters of the Yangtze Estuary.

Valuation of fisheries management status based on ecosystem approach (EA) in East Simeulue, Aceh

Fishery management is an activity that must be carried out to achieve sustainable fisheries. Fisheries management using the Ecosystem Approach to Fisheries Management (EAFM) approach is the sustainable use of fishery resources and protection of fish stocks in nature. One of the objectives of fisheries management in social and economic aspects is how fisheries can ensure the socio-economic welfare of the fishing community. Using fishing gear that is not environmentally friendly is one of the triggers for social conflict between fishermen and the uncertain selling price when the peak season of fish impacted the fishermen's economy. Therefore, the purpose of this research is to examine the socio-economic domain indicators from the aspect of EAFM-based coastal and marine resource ecosystem management. This research was conducted from January to February 2021, located in Simeulue District, Sub-District East Simeulue. The data collection method used in the study was interviews and field surveys. The determination of respondents is done by using a gradual sampling technique or stratified random sampling. Data analysis uses an ordinal-based Likert score of 1,2,3 for each indicator, namely the economic domain, fishery household income (RTP), savings ratio, asset ownership, and the social domain, namely stakeholder participation fisheries conflict and the use of local knowledge in fish resource management. Management status in East Simeulue District assessed the aggregate value of the economic domain in the medium category with a score of 48.3. Fishermen still earn less than the minimum wage, while in the social domain, it is in the excellent category with a score of 100 because fishermen, institutions, and related agencies work with each other.

Multi-indicator precautionary approach frameworks for crustacean fisheries

Implementation of precautionary approach (PA) management systems has generally proven to be a betterment over historic management practices in sustainable use of fisheries resources. However, PA management systems can minimize the application of holistic assessment advice. Single-indicator approaches, typically featuring a measure of stock biomass or abundance, have emerged as dominant in developing methods for PA frameworks. This often leads to advice generated from these frameworks being applied within narrowly focused decision-making pathways and can minimize management application of important ancillary factors. We argue this outcome is counter to the intent of PA management systems and that multi-indicator PA frameworks are a better approach. In this analysis, we detail the multi-indicator PA system development for demonstrative case studies focused on three lucrative fisheries resources in Newfoundland & Labrador, highlighting how multi-indicator PAs are potentially a better approach for the management of stocks with a contrasting range of ecological roles, socioeconomic importance, and data quality. The work is intended to generate a discussion on how PA frameworks should evolve to best suit management purposes.

Small innovation for sustainable use of fisheries resources

Influenced by Rio Declaration, Code of Conduct for Responsible Fisheries provided the principle toward sustainable fisheries in 1995. Reduction of wastages became a major issue. The author first accessed that the total amount of finfish discards in prawn trawling was similar to the coastal fisheries’ production in PNG and it was serious wastage. He also proved the over-estimation of global discards. A newly developed semi-demersal cuttlefish trammel-net successfully excluded bycatch of sub-legal individuals of flounder. He clarified that the process of declining of ghost fishing function after gear loss for cage trap and gillnet is represented with a survival function, on which the duration of ghost fishing and mortality were quantitatively estimated. He developed a technique for buoy line with an intermediate float to avoid entanglement of the line around seabed rocks. The author advocates research toward small innovation, through which many researchers can contribute to sustainable development.

Impact of human activity on the water quality of lake Mullinjëza, Belsh, Albania

Anthropogenic activities heavily influence lake ecosystems. This is due to population growth and the development of the industry and agriculture sectors. These activities include the intensified use of fishery resources, sewage discharge, polluting materials & substances, etc. The main aim of this study is to present an overview of the human impact on the pollution of the waters of Lake Mullinjëz. The many historical, cultural, ethnographic, architectural, and natural values that this city inherited from the past constitute a considerable potential for tourism. The objectives were to assess the lake water’s quality and propose measures for minimization and mitigation of impacts on the environment and the development of tourism in Belsh. Another important influential factor is the urban waste management near the lake which was through away along the shore of this lake. Sampling sites were selected to measure the impacts of potential sources of pollution, such as sewage discharge and urban waste. The results show that the quality of the water lake is very polluted. The most critical parameters of the water quality of Lake Mullinjëza are SS, PO43-, NO2-, NO3-, and NH4+. The most pronounced increase is observed in nitrites, nitrates, ammonium, TSS, TDS, and phosphates.

Research on the implementation and practice of the CCAMLR System of Inspection

Abstract The CCAMLR System of Inspection has been in place for more than 30 years, but its implementation and impact have yet to be summarised and analysed. The purpose of the research is to clarify the legal basis, analyse the implementation and make suggestions for further improvements. By analysing the CAMLR Convention and historical files, the System of Inspection has been further improved and many details have been added based on some international fisheries agreements and domestic laws regulating fisheries. Article XXIV of the CAMLR Convention, various Conservation Measures and documents form the legal basis of the System of Inspection. The System is divided into two types, namely At-sea inspection and Port inspection. Combined with the annual reports of CCAMLR meetings over the past 30 years, the System has become relatively complete as a “Compliance Monitoring Mechanism” under the CCAMLR Compliance Evaluation Procedure with other monitoring, control and surveillance (MCS) tools. However, inspection data have not been stable over the years. Since 2017, the increase in catches has not led to an increase in the number of inspections in the annual reports. In addition, At-sea inspections do not cover all Subareas of the Convention. At present, the objects of inspection have been extended to Non-Member vessels, so that it should also be sanctioned through various mechanisms. In addition, the System of Inspection is different from the Compliance Evaluation Procedure and the relationship between the two needs to be confirmed in practice. Due to the change in inspection methods, the lack of inspection data and the increase in other MCS tools, At-sea inspection does not cover all Subareas of the Convention. The System of Inspection is constantly being practised and improved. The study calls on Members to continue to carry out inspections and to improve the System in order to achieve the conservation and rational use of fishery resources.
