Kim, G.; Jeong, M.-H.; Jeon, S.-B.; Lee, T.-Y.; Oh, H.-Y., and Park, C.-S., 2021. Determination of optimal locations for offshore wind farms using the analytical hierarchy process. In: Lee, J.L.; Suh, K.-S.; Lee, B.; Shin, S., and Lee, J. (eds.), Crisis and Integrated Management for Coastal and Marine Safety. Journal of Coastal Research, Special Issue No. 114, pp. 439–443. Coconut Creek (Florida), ISSN 0749-0208. The ocean is one of the largest renewable energy sources. Offshore wind energy has attracted considerable attention owing to the increasing adoption of renewable energy technologies; therefore, it is vital to select the most appropriate sites for offshore wind farms. This study aims to select the optimal sites for offshore wind farms based on the analytical hierarchy process(AHP). This study considered 11 criteria: wind speed, water depth, distance from the shore, ship route density, military operations areas, marine ecosystem protection areas, marine biodiversity protection areas, special protected islands, protected areas for wildlife, cultural heritage sites, and national parks. The feasibility of potential sites for offshore wind farms was evaluated across the Korean Peninsula. The southern coast between Goheung and Yeosu is the most optimal area for installing offshore wind farms, followed by the west coast of Taean.

Benthic habitat mapping of Plazh Gradina - Zlatna ribka (Black Sea) and Karpathos and Saria Islands (Mediterranean Sea).

BackgroundHabitat mapping is nеcessary for the efficient conservation and protection of marine ecosystems. In addition, it is a requirement for EU Member States as stated in the European Union (EU) Habitats Directive (92/43/EEC), as well as necessary for the achievement and maintenance of 'good environmental status (GES)' of benthic marine habitats in the framework of the EU Marine Strategy Framework Directive (2008/56/EC).New informationThis study provides baseline information on the marine benthic habitats of Sozopol Bay (Black Sea) and Karpathos and Saria Islands (Mediterranean Sea). These two Natura 2000 sites were selected as study sites of the RECONNECT project, which aimed at creating a transnational cooperative network to confront the environmental threats of ecosystems with a high natural and cultural interest, by the establishment of common practices and a joint regional strategy. The specific objective was to map the marine habitats using a defined a priori classification (EUNIS), with the ultimate purpose of supporting government marine spatial planning, management and decision-making processes through the development of a Decision Support System.

Challenging the Need for Deep Seabed Mining From the Perspective of Metal Demand, Biodiversity, Ecosystems Services, and Benefit Sharing

The extraction of minerals from the seabed of the deep oceans is of increasing interest to investors, mining companies and some coastal states. To date, no commercial-scale deep seabed mining has taken place but there is considerable pressure for minerals mining to become an economic reality, including to supply the projected demand for metals to support a global transition to renewable energy. At the same time, the full environmental impacts of deep seabed mining are difficult to predict but are expected to be highly damaging, both within, and perhaps well beyond, the areas mined. Here, we reflect on the considerable uncertainties that exist in relation to deep seabed mining. In particular, we provide a perspective on: (1) arguments that deep seabed mining is needed to supply minerals for the green energy revolution, using the electric vehicle battery industry as an illustration; (2) risks to biodiversity, ecosystem function and related ecosystem services; and (3) the lack of equitable benefit sharing to the global community now and for future generations. We explore the justification for a global moratorium on deep seabed mining to ensure protection of marine ecosystems, the need to focus on baseline research, and how improved governance of targeted marine regions could be key to the preservation and conservation of the ocean biome.

How to Meet New Global Targets in the Offshore Realms: Biophysical Guidelines for Offshore Networks of No-Take Marine Protected Areas

Networks of no-take marine protected areas (MPAs), where all extractive activities are prohibited, are the most effective tool to directly protect marine ecosystems from destructive and unsustainable human activities. No-take MPAs and MPA networks have been globally implemented in coastal seas, and their success has been significantly enhanced where science-based biophysical guidelines have informed their design. Increasingly, as human pressure on marine ecosystems is expanding further offshore, governments are establishing offshore MPAs—some very large—or MPA networks. Globally, there are growing calls from scientists, non-government organisations, and national governments to set global conservation targets upwards of 30%. Given that most of the ocean is found either in the high seas or offshore within national Exclusive Economic Zones, large offshore MPAs or networks of MPAs must be a major component of these global targets for ocean protection. However, without adequate design, these offshore MPAs risk being placed to minimise conflict with economic interests, rather than to maximise biodiversity protection. This paper describes detailed biophysical guidelines that managers can use to design effective networks of no-take MPAs in offshore environments. We conducted a systematic review of existing biophysical design guidelines for networks of MPAs in coastal seas, and found consistent elements relating to size, shape, connectivity, timeframes, and representation of biophysical features. However, few of the guidelines are tailored to offshore environments, and few of the large offshore MPAs currently in place were designed systematically. We discuss how the common inshore design guidelines should be revised to be responsive to the characteristics of offshore ecosystems, including giving consideration of issues of scale, data availability, and uncertainty. We propose 10 biophysical guidelines that can be used to systematically design offshore networks of MPAs which will also contribute to the global goal of at least 30% protection globally. Finally, we offer three priority guidelines that reflect the unique conservation needs of offshore ecosystems: emphasising the need for larger MPAs; maximising the inclusion of special features that are known and mapped; and representing minimum percentages of habitats, or, where mapped, bioregions. Ultimately, MPA guidelines need to be embedded within an adaptive management framework, and have the flexibility to respond to emerging knowledge and new challenges.

Effectiveness and design of marine protected areas for migratory species of conservation concern: A case study of post-nesting hawksbill turtles in Brazil

Marine protected areas (MPAs) are among the most widely used strategy to protect marine ecosystems and are typically designed to protect specific habitats rather than a single and/or multiple species. To inform the conservation of species of conservation concern there is the need to assess whether existing and proposed MPA designs provide protection to these species. For this, information on species spatial distribution and exposure to threats is necessary. However, this information if often lacking, particularly for mobile migratory species, such as marine turtles. To highlight the importance of this information when designing MPAs and for assessments of their effectiveness, we identified high use areas of post-nesting hawksbill turtles (Eretmochelys imbricata) in Brazil as a case study and assessed the effectiveness of Brazilian MPAs to protect important habitat for this group based on exposure to threats. Most (88%) of high use areas were found to be exposed to threats (78% to artisanal fishery and 76.7% to marine traffic), where 88.1% were not protected by MPAs, for which 86% are exposed to threats. This mismatch is driven by a lack of explicit conservation goals and targets for turtles in MPA management plans, limited spatial information on species' distribution and threats, and a mismatch in the scale of conservation initiatives. To inform future assessments and design of MPAs for species of conservation concern we suggest that managers: clearly state and make their goals and targets tangible, consider ecological scales instead of political boundaries, and use adaptative management as new information become available.

An Assessment of Marine Ecosystem Damage from the Penglai 19-3 Oil Spill Accident

Oil spills have immediate adverse effects on marine ecological functions. Accurate assessment of the damage caused by the oil spill is of great significance for the protection of marine ecosystems. In this study the observation data of Chaetoceros and shellfish before and after the Penglai 19-3 oil spill in the Bohai Sea were analyzed by the least-squares fitting method and radial basis function (RBF) interpolation. Besides, an oil transport model is provided which considers both the hydrodynamic mechanism and monitoring data to accurately simulate the spatial and temporal distribution of total petroleum hydrocarbons (TPH) in the Bohai Sea. It was found that the abundance of Chaetoceros and shellfish exposed to the oil spill decreased rapidly. The biomass loss of Chaetoceros and shellfish are 7.25×1014~7.28×1014 ind and 2.30×1012~2.51×1012 ind in the area with TPH over 50 mg/m3 during the observation period, respectively. This study highlights the evaluation of ecological resource loss caused by the oil spill, which is useful for the protection and restoration of the biological resources following the oil spill.

Estimating benthic trophic levels to assess the effectiveness of marine protected area management

Designating and managing marine protected areas (MPAs) can mitigate many ocean threats. Banning fishing activities within MPAs enhances the robustness of food-web dynamics and thus increases trophic resilience. Ecosystem function indicators, such as mean trophic level, are increasingly applied in conservation management. Stable isotope analysis is a common tool in trophodynamic studies as it provides information about food sources and trophic level within food webs. In contrast to the traditional top-down approaches in conservation management (mainly for fisheries), this study focuses on bottom-up responses to protection according to the target species in regional small-scale fisheries. The present study aimed to examine how MPA status affects trophodynamics in the rocky reefs of the Illas Atlánticas Marine-Terrestrial National Park (Galicia, NW Spain). Results showed no differences between inside and outside the MPA in species stable isotopic signatures or trophic level. However, these results should be considered with caution due to some limitations in the study design (small number of sites per location, biogeographic differences associated with the island nature of the MPA, or seasonal variability). Nevertheless, the lax fishing management, the lack of proper implementation (the MPA was established in 2002 without a management plan until 2019), and the small size of the studied MPA may result in ineffective conservation outcomes that could have been reflected in the stable isotopic content of the food web. The large number of “paper park” MPAs existing worldwide are not only detrimental to the perception of marine protection, but also provide poor protection of marine ecosystems. Subject to further studies accounting for both environmental and management factors on stable isotope signatures, trophic interactions can form a cost-effective tool for monitoring MPA effectiveness.

The Multi-Partner Research Initiative: A Scientific Research Network to Support Decision Making in Oil Spill Response

ABSTRACT The Government of Canada's Oceans Protection Plan (OPP) is a comprehensive, transformative $1.5 billion strategy to build a world-leading marine safety system to protect marine ecosystems, while enabling inclusive economic growth. A key component of the OPP is the Multi-Partner Research Initiative (MPRI), led by Fisheries and Oceans Canada (DFO) in collaboration with other federal agencies (Environment and Climate Change Canada, Canadian Coast Guard, Natural Resources Canada, and Transport Canada), that aims to advance oil spill research by fostering a national/international research network that brings together scientific experts in the field. The core studies under this program are focused on the provision of scientific knowledge to support the development, validation and regulatory approval of Alternative Response Measures (ARMs) that include: spill treating agents, in situ burning, oil translocation and decanting/oily waste disposal. Additional research includes studies on key “cross-cutting” issues, such as natural attenuation and bioremediation of oil, assessment of toxic impacts associated with oil spills and the application of oil spill countermeasures, and oil detection and mapping by autonomous underwater vehicles (AUVs). The deliverables from this research program will provide essential information to support Net Environmental Benefit Analysis (NEBA) for decision making to select the optimal oil spill response option(s) to protect the marine environment and its living resources. With an emphasis on supporting the development of the next generation of scientists in the field through engagement with the private sector (i.e., spill response organizations and oil industry partners) and other international (e.g., USA, Norway, France, Australia, China) government agencies, MPRI is anticipated to have a profound influence on the oil spill research community and emergency response agencies within Canada and abroad.

The Case of Lionfish (Pterois miles) in the Mediterranean Sea Demonstrates Limitations in EU Legislation to Address Marine Biological Invasions

The European Regulation (EU) 1143/2014 on Invasive Alien Species entered into force in 2015, with the aim to fulfill regional and international biodiversity goals in a concerted manner. To date, the Regulation listed 66 Invasive Alien Species (IAS) that are subject to legal controls. Only one of these is marine. A recent lionfish (Pterois miles) invasion has been closely monitored in the Mediterranean and a detailed risk assessment was made about the profound impacts that this invasive fish is likely to have on the fisheries and biodiversity of the region. In 2016–21, lionfish rapidly became dominant predators along Eastern Mediterranean coasts, yet the process for their inclusion on the EU IAS list has been lengthy and is ongoing. There is an urgent need to learn from this experience. Here, we recommend improvements to the Regulation 1143/2014 and the risk assessment process to protect marine ecosystems and secure the jobs of people that rely on coastal resources.

Science Popularization-oriented Art Design of Interactive Installation based on the Protection of Endangered Marine Life-the Blue Whale

In today’s world, marine pollution is becoming more and more serious, and the protection of marine ecosystems and endangered marine organisms has become an important international issue. In 2012, the blue whale was officially listed on the IUCN Red List of Threatened Species. As the top predator in the ocean, blue whales are seeing a drastically decreasing population, which will break the ecological balance of the region. The interlocked food chain in the ocean means it would eventually lead to the forming of an “ocean desert”. Therefore, it is urgent to start the popularization of science to protect the endangered marine organisms for the public. Based on human-computer interaction and sound visualization, the author designs an interactive installation with the theme of “The Last Whale Sound”, aiming to increase the public’s attention to endangered marine organisms, to arouse people’s self-reflection and environmental awareness, and to make the public consciously participate in protecting marine ecosystems.

Durable Freshwater Protection: A Framework for Establishing and Maintaining Long-Term Protection for Freshwater Ecosystems and the Values They Sustain

Long-term protection is needed to secure threatened freshwater ecosystems and the social and biodiversity values they provide. In the face of existing and future pressures, current approaches to freshwater protection are often inadequate for maintaining ecosystem values into the future. While terrestrial and marine ecosystem protection are well recognized and have area-based protection goals in global conventions, freshwater ecosystem characteristics have remained poorly represented in these goals. Freshwater ecosystems are commonly secondary or unaddressed components of area-based terrestrial protection. The design and management for terrestrial-based protection are generally inadequate for addressing freshwater ecosystem processes and attributes critical for maintaining their natural patterns and the values they provide to people and nature. Given that freshwater-dependent species are declining at a faster rate than marine and terrestrial species, and the reliance and use of freshwater ecosystems by people living around such areas, approaches to protect them must balance the needs of people and nature and accommodate these complexities.

Variations of Water Transparency and Impact Factors in the Bohai and Yellow Seas from Satellite Observations

Water transparency, measured with Secchi disk depth (SDD), is an important parameter for describing the optical properties of a water body. This study evaluates variations of SDD and related impact factors in the Bohai and Yellow Seas (BYS). Based on a new mechanistic model proposed by Lee et al. (2015) applied to MODIS remote sensing reflectance data, climatological SDD variation from 2003 to 2019 was estimated. The annual mean images showed an increasing trend from the coastal zone to the deep ocean. Lower values were found in the Bohai Sea (BHS), while higher values observed in the center of the southern Yellow Sea (SYS). Additionally, the entire sea has shown a decreasing temporal tend, with the variation rate lowest in the BHS at 0.003 m y−1, and highest in the SYS at 0.015 m y−1. However, the weak increasing trend that appeared since 2017 suggests that water quality seems to have improved. Further, it displayed seasonal patterns of low in winter and spring and high in summer and autumn. The empirical orthogonal function (EOF) analysis of SDD variations over the BYS, shows that the first SDD EOF mode is the highest, strongly correlated with total suspended matter. With the high correlation coefficients of chromophoric dissolved organic matter, it illustrates that the SDD variation is mainly dominated by the optical components in the seawater, although correlation with chlorophyll-a is the weakest. The second and third EOF modes show that photosynthetically available radiation, sea surface temperature, sea surface salinity, and wind speed are the main covariates that cause SDD changes. Water transparency evaluation on a long-term scale is essential for water quality monitoring and marine ecosystem protection.

ПРАВОВИЙ СТАТУС ІНОЗЕМНИХ ВІЙСЬКОВИХ КОРАБЛІВ ЯК ЕКОЛОГІЧНО НЕБЕЗПЕЧНИХ ОБ’ЄКТІВ

The article describes the practical experience of the NATO Navy’s environmental activities in the protection of marine ecosystems. The article uses publications on the protection of marine ecosystems, the ecological status of the Black and Azov Seas and environmental control. The physical and geographical characteristics of the Black Sea and the ecological conditions of the Azov-Black Sea are described. Data from the ecological monitoring of the Azov-Black Sea region indicate a severe ecological crisis in the region, which is characterized by excessive development of unicellular algae, death of fish and dolphins. The intensification of the ecological crisis coincided with the beginning of the militarization of the Azov-Black Sea region. The presence of foreign warships will further intensify the environmental crisis in the Black Sea. There is a need for legislative regulation of the naval activities of NATO countries in the territorial and internal waters of Ukraine. Today, the current legislation of Ukraine requires to determine the normative nature of navigation and stay of foreign warships in the territorial and internal waters of Ukraine, to determine recommended courses or sea corridors for foreign warships, to establish areas where military presence and military exercises are prohibited. The environmental legislation of Ukraine should provide rules for environmental safety in the operation of foreign warships, rules for storage and disposal of waste, rules for the destruction of ammunition that has not been used, defines the procedure for compensation for environmental damage from naval activities. So far, these issues have not been regulated by law. The method of calculating damage from foreign warships has not been created or put into effect. In the long run, it is necessary to conduct ecological studies of the North-Western part of the Black Sea to determine the areas closed to naval activities. Keywords: warship, Black Sea, marine ecosystem, maritime law, naval forces, high seas.

The article describes the practical experience of the NATO Navy’s environmental activities in the protection of marine ecosystems. The article uses publications on the protection of marine ecosystems, the ecological status of the Black and Azov Seas and environmental control. The physical and geographical characteristics of the Black Sea and the ecological conditions of the Azov-Black Sea are described. Data from the ecological monitoring of the Azov-Black Sea region indicate a severe ecological crisis in the region, which is characterized by excessive development of unicellular algae, death of fish and dolphins. The intensification of the ecological crisis coincided with the beginning of the militarization of the Azov-Black Sea region. Further development of the Ukrainian Navy will lead to even greater destruction of marine ecosystems and large losses of valuable natural resources. The article gives examples of environmental activities of the Australian, British and US navies, which pay great attention to the protection of the marine environment and environmental planning of their activities. The current protection state of the marine ecosystems in the Ukrainian Navy is considered in this article. Recommendations for greening the activities of the Ukrainian Navy in the context of the ecological crisis of the Black and Azov Seas are given: develop and implement measures to protect marine animals during marine exercises; implement programs to protect marine ecosystems, especially those of high ecological value; to provide clearing of the remains of ammunition; creation and implementation of an environmental management system for all Navy facilities; to carry out updating and re-equipment of ships taking into account requirements of MARPOL; to ensure compliance with environmental requirements in the design, construction, operation, repair and disposal of Navy ships. The study of experience in the protection of marine ecosystems of the NATO Navy will enable the Ukrainian Navy to make appropriate management decisions and balance its activities in the Black and Azov Seas, taking into account the increased man-made load. Keywords: pollution, wastes, Azov-Black Sea region, naval activity, marine ecology.

Alteration of coastal productivity and artisanal fisheries interact to affect a marine food web

Top-down and bottom-up forces determine ecosystem function and dynamics. Fisheries as a top-down force can shorten and destabilize food webs, while effects driven by climate change can alter the bottom-up forces of primary productivity. We assessed the response of a highly-resolved intertidal food web to these two global change drivers, using network analysis and bioenergetic modelling. We quantified the relative importance of artisanal fisheries as another predator species, and evaluated the independent and combined effects of fisheries and changes in plankton productivity on food web dynamics. The food web was robust to the loss of all harvested species but sensitive to the decline in plankton productivity. Interestingly, fisheries dampened the negative impacts of decreasing plankton productivity on non-harvested species by reducing the predation pressure of harvested consumers on non-harvested resources, and reducing the interspecific competition between harvested and non-harvested basal species. In contrast, the decline in plankton productivity increased the sensitivity of harvested species to fishing by reducing the total productivity of the food web. Our results show that strategies for new scenarios caused by climate change are needed to protect marine ecosystems and the wellbeing of local communities dependent on their resources.

Uncovered pathways: Modelling dispersal dynamics of ship‐mediated marine introduced species

Abstract Marine traffic is the main vector for marine non‐indigenous species (NIS) that may hitchhike in ballast water tanks or attached to vessel hulls. Understanding marine traffic dynamics and estimating the associated risk of NIS dispersal reveals points of leverage for preventive NIS management. This study presents a method to quantify the risk of ship hull fouling‐mediated NIS dispersal and identifies main dispersal hubs in marine traffic networks. We use the Galapagos Marine Reserve (GMR) as a case study to test the applicability of this method. Ship position data derived from the automatic identification system (AIS) served as a basis for a network consisting of nodes (moorings and anchorages) and edges (ship routes). Wetted surface areas (WSA) describe the parts of vessel hulls submerged by water and were used to parameterize dispersal risks of individual vessels. We combined the constructed network with a numeric dispersal model and sequentially removed network elements to test their effectiveness on decreasing the overall dispersal capacity. Marine traffic hotspots, such as ports and popular marine visitor sites, represented the main dispersal hubs and incoming edges into the GMR crucial links for the overall dispersal capacity. The removal of passenger vessels had the strongest effect on the overall dispersal capacity, reducing it to 1%. Based on our findings, we suggest management recommendations to curb the spread of marine NIS in the GMR, including the implementations of (a) vessel hull controls at main dispersal hubs (ports); (b) species monitoring programmes at popular marine visitor sites and (c) hull husbandry regulations for passenger vessels. Synthesis and application. In an increasingly connected world, the development of risk assessments for marine non‐indigenous species (NIS) dispersal is a crucial step towards the sustainable use and protection of marine ecosystems in Galapagos and other places. The presented methodology is solely based on the pathway component and thus applicable to any place with available ship position data. Therefore, it may provide useful baseline information for preventive measurements especially in places where ecological data about NIS are scarce.

Implications of new technical measures regulation for cetacean bycatch in European waters

For decades, cetacean bycatch has been a major conservation and welfare concern in the European Union with high numbers of harbour porpoises, dolphins and whales dying each year. Despite binding legal requirements to monitor and reduce bycatch, cetacean bycatch monitoring has been insufficient in most fisheries and areas to generate reliable estimates of bycatch rate. Measures to reduce bycatch have been limited and not always directed at the most problematic fisheries. EU cetacean bycatch legislation (Council Regulation (EC) No. 812/2004) was repealed and replaced by a new Regulation, Regulation on the conservation of fishery resources and the protection of marine ecosystems through technical measures (2019/1241). Whilst some improvements have been made in the new Regulation, scientific advice of the ICES Bycatch Working Group (ICES WGBYC), and other expert regional bodies, such as ASCOBANS and ACCOBAMS, were not incorporated explicitly and some measures in the adopted Technical Measures Regulation weaken both the provisions of the existing cetacean bycatch legislation and the Commission’s original proposal. The bycatch measures adopted for cetaceans are not sufficient to mitigate bycatch effectively in European waters. Management solutions to reduce bycatch are identified and a number of general recommendations towards development of national and regional management plans, implementation and enforcement to that end are made.

Water quality criteria for selected pharmaceuticals and personal care products for the protection of marine ecosystems

Pharmaceuticals and personal care products (PPCP) are increasingly detected in estuarine and coastal waters and organisms but they are absent from lists of priority substances and no environmental quality criteria are available for these chemicals. Ten PPCP were selected on the basis of their occurrence and reported biological effects, oxytetracycline (OTC), sulfamethoxazole (SUL), ibuprofen (IBU), diclofenac (DCF), sertraline (SER), fluoxetine (FLU), carbamazepine (CAR), propranolol (PRO), benzophenone-3 (BP3), and triclosan (TCS). For these chemicals, probabilistic and deterministic water quality criteria (WQC) were derived from their species sensitive distribution (SSD) curves and the critical values respectively, prioritizing ecotoxicological information obtained with sensitive early-life stages of marine organisms. For most PPCP, the probability that the log-logistic model provided better fit than the log-normal model to the SSD was >95%. Using the lower end of the 5th percentile 95% confidence interval, resulting WQC ranged from 1 to 6 μg·L−1 for OTC, IBU, SER, FLU, PRO and TCS. In contrast WQC derived applying the assessment factor method were consistently more conservative, ranging from 0.01 to 0.54 for the same chemicals.

A New Long-Term Marine Biodiversity Monitoring Program for the Knowledge and Management in Marine Protected Areas of the Mexican Caribbean

In the Mexican Caribbean, 15 marine protected areas (MPAs) have been established for managing and protecting marine ecosystems. These MPAs receive high anthropogenic pressure from coastal development, tourism, and fishing, all in synergy with climate change. To contribute to the MPAs’ effectiveness, it is necessary to provide a long-term observation system of the condition of marine ecosystems and species. Our study proposes the establishment of a new marine biodiversity monitoring program (MBMP) focusing on three MPAs of the Mexican Caribbean. Five conservation objects (COs) were defined (coral reefs, seagrass beds, mangroves, marine turtles, and sharks-rays) for their ecological relevance and the pressures they are facing. Coral reef, seagrass and mangroves have multiple biological, biogeochemical and physical interactions. Marine turtles are listed as endangered species, and the status of their populations is unknown in the marine area of the MPAs. Elasmobranchs play a key role as top and medium predators, and their populations have been poorly studied. Indicators were proposed for monitoring each CO. As a technological innovation, all information obtained from the MBMP will be uploaded to the Coastal Marine Information and Analysis System (SIMAR), a public, user-friendly and interactive web platform that allows for automatic data management and processing.

LAW ENFORCEMENT OF DESTRUCTIVE FISHING IN INDONESIAN SEAS

Indonesia is a country consisting of many islands. This makes Indonesia rich in natural marine resources consisting of marine products such as fish and other marine animals. Catching fish by means of damage or (destructive fishing) using trawlers, fish bombs, fish anesthesia needs special attention in terms of law enforcement, to support the protection of marine ecosystems and enforcement of existing regulations. This study uses a qualitative method with a normative juridical approach. This research shows weaknesses in committing destructive fishing crimes. This is intended so that law enforcers can enforce according to the provisions of the statutory regulations that are willing, and seek additional personnel or carry out strategies so that they can carry out surveillance in the Indonesian sea from catching fish in destructive ways.
