ANALYSIS Catch Per Unit Effort (CPUE) AND Maimum Sustainable Yield (MSY) MALE MACKEREL (Rastrelliger kanagurta) FLYING IN THE SAMUDERA FISHING LAND (PPS) KENDARI

The Banda Sea is an Indonesian water body that holds potential for small pelagic fisheries resources. Situated between Sulawesi Island and Maluku, it is part of the Fisheries Management Area Of The Republic Of Indonesia (WPP-NRI 714), Male mackerel (Rastrelliger kanagurta) is one of the fish species with high economic value, greatly favored by the community for consumption. This has led to an increase in its capture rates. Therefore, the research aims to determine the CPUE and MSY of Indian mackerel in the Kendari Ocean Fisheries Port. Data collection was conducted at the Kendari Ocean Fisheries Port from logbooks, and the research lasted from November to December 2023. The results showed that the standard fishing gear used to catch these fish is purse seine. The status of the utilization of the fishery resources is said to be experiencing underfishing. Based on the research results, the maximum sustainable yield (MSY) is 96,386 kg/year, with an optimal fishing effort of 2,300 trips/year (Fox model).

Analysis of the Status of Sustainable Utilization and Management of Flyfish (Decapterus russelli) Resources in Pasongsongan Waters, Sumenep Regency using the Walter-Hilborn Model

Flyfish (Decapterus russelli) is a small pelagic fish with a fairly high economic value. Flying fish are the fish with the highest production landed at the Pasongsongan Beach Fisheries Port, Sumenep Regency. In recent years, the production of flying fish in Pasongsongan has continued to decline, excessive fishing activities and an increase in the number of fleets are feared to interfere with the sustainability of flying fish resources. Therefore, sustainable management of flyfish resources needs to be carried out, the purpose of this study is to find out the sustainable potential of flyfish resources, to know the number of catches allowed, and to know the status of the utilization of flyfish resources in Pasongsongan waters. The methods used in this study are quantitative and qualitative methods. The analysis used is a surplus production approach using 3 models, namely the Schaefer model, the Fox model and the Walter-Hilborn model. The results of the analysis using the Walter Hilborn model are a surplus production model that is suitable for use with a maximum catch value (Ymsy) of 2,255 tons and a permissible catch (JTB) of 1,804 tons, the utilization rate of flying fish landed in PPP Pasongsongan is 87% with the utilization status in the Fully Exploited category, where in this condition illustrates that the stock of resources has been exploited by 75-100%. An increase in the number of fishing efforts is not recommended even though the number of catches can still increase because it will interfere with the sustainability of fish resources.

ASSESSMENT OF THE RESOURCES SUSTAINABILITY USING RESOURCE UTILISATION AND CATCH PROJECTION APPROACH: CASE OF PRIGI GULF INDONESIA

Utilisation of fisheries resources requires good management to maintain the sustainability of fish resources. Based on these conditions, this study aims to analyse the status of fish resource utilisation and estimate fish catches in the following year. The data collection is secondary data from Prigi Fishery Port, East Java, from June to September 2023. This study evaluates biological surplus production relationships. Next, due to the time series data, the forecasting performance uses Holt-Winter’s exponential smoothing. The modelling shows that the best estimation value in the Fox model is based on the highest R2 (0,614) and the effort coefficient (0.000034). The maximum sustainable yield (CMSY) and the optimum catch effort (EMSY) values were 10.006 tonnes/year and 29,425 trips/year, respectively. It shows that biological overfishing has yet to occur. The average production forecasting results in 2021-2023 decreased 8.5% from the previous year. Forecasting fish catches in 2021 exceeds CMSY, but in 2022 and 2023, production is still below CMSY. The circumstance indicates that fishing operations are inefficient because the catch obtained is projected to be smaller with fixed effort. Possible management strategies, therefore, include creating sustainable fisheries management through improved work variation for fishers in the off-season.

Management of Swanggi Fish (Priacanthus Macracanthus) in the Waters of the Port of Nusantara Fishery Port Ratu

Indonesia has two-thirds of its territory covered by sea, making it rich in marine resources, especially fish. According to the Census of Marine Life, there are around 950 thousand species that inhabit the world's oceans, but only about one percent have been exploited. In Indonesia itself, FishBase records around 4743 types of fish, making it the country with the largest Marine Mega-Biodiversity in the world (Jabbar, 2018). There are two main problems in the fisheries sector in Indonesia: economics and biology. Biological problems include threats to the sustainability of fish stocks, while economic problems are related to the lack of profits obtained by fishermen from catches and sustainable use of fish resources (Akoit and Nalle, 2018). The Archipelago Fisheries Port (PPN) plays an important role in supporting fishing activities in the Indian Ocean, including in Palabuhanratu, West Java. Palabuhanratu is an important location for landing various types of fish, especially large pelagic fish such as tuna and skipjack, as well as swanggi fish (Priacanthusmacracanthus), which experienced a significant increase in production from 573 tonnes in 2013 to 18,730 tonnes in 2015 (Sadewi et al., 2018). Swanggi fish is a demersal fish with high economic value that is in demand by the public and is an export commodity to Korea, Japan and China. However, high demand results in overfishing and a decline in adult fish stocks (Jabbar et al., 2017). This research is descriptive quantitative research which aims to measure the level of variables through samples. The analytical methods used include analysis of biological aspects of swanggifish, catch analysis methods, and sustainability analysis methods using Rapid Appraisal for Fisheries (RAPFISH). It is hoped that the results of this research can provide a sustainable shrimp resource management strategy based on the data obtained.

ANALISIS HASIL TANGKAPAN IKAN TONGKOL YANG DIDARATKAN DI PELABUHAN PERIKANAN NUSANTARA AMBON

This research aims to analyze the catches of tuna landed at the Ambon Nusantara Fisheries Port. The research was conducted for two months, from January to February 2023, using descriptive methods. Primary data was collected through direct observation and interviews with fishermen and port officers, while secondary data was obtained from PPN Ambon. The results of this research show that the catch was landed by four fishing fleets, namely purse seines, gill nets, fish trawls and lines fishing. The total catch landed during the 2012-2021 period was 510,203 tons, which was dominated by Auxis thazard. Purse seines are the most dominant fishing gear used, contributing 52.1% of the total catch with a total fishing effort of 597 trips. The productivity of the fishing fleet fluctuates from year to year, the lowest productivity for Euthynnus affinis occurred in 2018 and the highest in 2013, while the lowest productivity forl Auxis thazard occurred in 2017 and the highest in 2018. Fluctuating and low productivity indicates the existence of potential for overfishing. This research suggests the need for further analysis regarding the potential and level of utilization of the two species of frigate tuna landed in PPN Ambon

Analysis of the potential and level of utilization of skipjack tuna (Katsuwonus pelamis) landed at Sadeng Coastal Fishery Port (PPP), Gunungkidul Yogyakarta, Indonesia

Sadeng waters are one of the distribution areas for skipjack tuna (Katsuwonus pelamis), which can be found almost every month and can even be found every day if the fishing season is right, namely February to March or September to October. Sadeng coastal Fishery Port (PPP) has a role as a center of economic activity and plays a role in developing fishing technology. Capture fisheries businesses, and other activities related to the fisheries and marine sectors. The aim of this research is to examine the potential aspects of K. pelamis resources and analyze the optimal use of K. pelamis resources. By assessing the potential of fisheries resources to determine the Maximum Sustainable Yield (MSY) value, information can be obtained on the level of utilization and level of effort. This research was carried out from February to May 2023 on a purse seiner. Sadeng Waters, Yogyakarta, Indonesia. Tools and materials used include cameras, stationery and questionnaire sheets. Primary data and secondary data collection methods use 4 (four) methods, namely observation, interview, documentation and literature study. The research results show that the level of utilization of K. pelamis in Gunungkidul Regency is experiencing overfishing conditions. The highest utilization rate occurred in 2020 at 132%. The potential fish resources in Gunungkidul Regency are the average production of K. pelamis in 2018 to 2022 of 18,122 tons. Based on analysis (MSY) and (Fopt), K. pelamis resources from 2018 to 2022 have reached over fishing. The high level of utilization of K. pelamis occurs due to a lack of supervision from the relevant agencies regarding the recording of production results from fishing vessels based at PPP Sadeng.

Quality Control of Skipjack Fish on Purse Seine Vessels at PPS Kutaraja

The research aims to analyze the handling system for skipjack tuna since the fish are caught until sold at the Kutaraja Ocean Fisheries Port (PPS) fish auction site (TPI). The researcher used descriptive methods, organoleptic tests, scoring analysis, and np control charts as study methods. The research results show that the handling of skipjack tuna at the Kutaraja PPS has yet to be optimal, which has an impact on reducing the quality of the fish. The handling process that did not comply with the established procedures occurred from when the fish was put on the boat until it landed at PPS Kutaraja. The results of organoleptic tests, scoring analysis, and np control charts indicated a decrease in fish quality during the handling process. All ships based at PPS Kutaraja are not equipped with freezer cooling machines. The cooling process only relies on a very limited amount of ice blocks to maintain the quality of the fish during the fishing operation. Very limited use of ice cubes will trigger a decline in fish quality. Increasing hatch room temperatures also cause a significant decrease in organoleptic values and faster rigor mortis times for fish.

Investigation of sorption behavior of 137Cs in a river–sea system boundary area after the Fukushima Dai-ichi nuclear power plant accident

The radiocesium (137Cs) distribution between dissolved and particulate phases was examined in river water and coastal seawater as a function of the 137Cs sorption behavior on suspended particles. Dissolved 137Cs activity concentrations in the Tomioka River (salinity <0.1), about 10 km south of Fukushima Dai-ichi Nuclear Power Plant, and in coastal seawater at Tomioka fishery port (salinity >30), Fukushima Prefecture, from June 2019 to October 2021 were 3.6–20 Bq/m3 (geometric mean 11 Bq/m3) and 2.4–86 Bq/m3 (13 Bq/m3), respectively. Although the suspended particle concentration was lower in the river than in seawater, the mean 137Cs activity on suspended particles was 11,000 Bq/kg-dry in the river versus 3200 Bq/kg-dry in seawater. Proportions of ion-exchangeable, organically bound, and refractory fractions of 137Cs on suspended particles were determined by sequential extraction. The ion-exchangeable fraction accounted for 0.3–2.0% (average: 1.2%) and 0.4–1.3% (0.8%) at the river and port sites, respectively. The organically bound fraction accounted for 0.3–4.8% (1.8%) and 0.1–5.5% (2.1%) at the river and port sites, respectively. In both areas, the refractory fraction accounted for >90% of 137Cs. Therefore, the small labile 137Cs fraction on suspended particles in coastal seawater indicates that the mobility of 137Cs to marine biota is quite low. SynopsisThis study is the first to examine radiocesium sorption forms on suspended particles in coastal seawater near the Fukushima Dai-ichi Nuclear Power Plant. It suggests immobility of 137Cs in suspended particles being incorporated to marine biota.

PEMETAAN KAPAL TERBENGKALAI BERBASIS WEB DI WILAYAH OPERASIONAL PERAIRAN PPN KARANGANTU

The current condition of the Karangantu Archipelago Fisheries Port (PPN) is still considered unfavorable because the operational area of ​​the port waters looks dirty and shabby. There are many ships that are no longer used in the Karangantu PPN operational area. Based on the results of interviews with PPN Karangantu officers, there are several things that cause ships to be abandoned in the operational area of ​​PPN Karangantu waters, including the age of the ship, costs or capital, and human resources. Abandoned ships that are not immediately handled will result in obstacles to the flow of water traffic at the port and create a risk of collision for other ships passing by. Therefore, web-based mapping of abandoned ships (WebGIS) is needed in the operational area of ​​PPN Karangantu waters. It is hoped that the results of this abandoned ship mapping can be used by the port to report abandoned ships to the center so that they can immediately take action to transport the abandoned ships. With the existence of WebGIS mapping abandoned ships, the port does not need to go directly to the field to find the location of abandoned ships because the information can be accessed via the web that has been created. Data collection on coordinate points was carried out by field survey and tagging using the GPS Map Camera application. The research results show that there are 74 abandoned ships in the Karangantu PPN operational area.
