The utilization of glass eel (eel seeds) in the Cimandiri River Palabuhanratu has a very important role to support the supply chain for the eel culture industry. The purpose of this study was to estimate the amount of glass eel catch, describe the glass eel eel supply chain system, and measure the performance of the supply chain in eel culture. The research method uses quantitative methods through direct observation and interviews, as well as case studies of supply chain actors. The results showed that the highest catch of glass eel in 2019 was in June at an average of 14,859 grams (14.9 kg). The highest catch of glass eel occurred in the dry season (June - August), with a total catch of 21,884 grams (21.8 kg). The glass eel supply chain mechanism consists of supply chain flow pattern on the product flow, a good and transparent flow of information on each link, and the distribution of two payment systems, namely cash and credit payments. The supply chain performance in the eel culture industry obtained a performance value of 82.63 which indicates that the achievement of the company's supply chain performance is in the good category, and improvements need to be made especially on the deliver process performance indicators with a value of 2.70.

This research was aiming at analysing ergonomic aspects and identifying potential hazards resulted from fishing activities. Data was collected from a long line fishing vessel MV Satelit. Analysis of ergonomic aspects focused on four major activities namely setting, drifting, hauling and fish handling. The investigation was conducted to examine the suitability of on board working area with fishermen’s movement. The result showed that on board working area was inadequate compared to fishermen’s movement because of limited zones for fishermen (ranged from 1 – 3 m2/ person) without any safety equipment. Based on Job Safety Analysis (JSA), it was revealed that there were 14 potential hazards emerging from fishing activities; 64,29% of them were moderate risk and the rest were trivial risk. However, fishermen have no significant efforts to prevent those hazards. Keywords: : ergonomic, fishing vessel, occupational health and safety, tuna fishing, potential hazards

In the Ministry of Fisheries and Marine Affair Decree No. 45/2014 stated that an environmental consideration should take into account in controlling waste in fishing port area, including ship-generated waste. Marine pollution is one of the factors cause environmental damage including marine environment. Fishing activities is one of activites that has the potential to cause pollution of the sea. The objective of this research was to identify the waste type generated by fishing vessels and identify fishermens’s behavior patterns on the waste handling. The research was conducted in PPN Palabuhanratu (Palabuhanratu Nusantara Fishing Port). The data of waste type were collected from all kind of fishing vessels that grouped base on their dimension. The results show that, organic waste dominated the waste compotition, and from the fishers habit point of view most fishers still ignore the importance of marine pollution prevention effort. It showed from their habit to dispose waste not in the rigt place. Keywords: : fishing boats, marine pollution, organic waste, PPN Palabuhanratu

Fishing with purse seine fishing gear has been carried out by many fishermen, which are generally aimed at catching pelagic fish. Jepara District is one of the coastal areas of the North Coast of Java, located in Central Java Province. This condition makes Jepara Regency have a marine-based economic side of life which has the potential of fish resources that have been used by local fishermen for a long time. The current condition has a tendency to decline in production, which is thought to be due to overfishing. This study aims to obtain an overview of the dominant fish caught by the purse seine and to see the productivity of the purse seine. The research method used is a survey method, by conducting interviews with 20 fishermen, the head of the Ujungbatu Fish Auction Place (TPI) and his staff. The data obtained are data on catch production, composition of types of catch and other data. The results are expected to be able to provide an overview of the dominant fish catch and productivity of purse siene in the waters of Jepara District. The conclusion that can be drawn from this research is that there are three types of fish that are dominant catch, namely layang fish, mackerel and squid. During the last five years (from 2015 - 2019), production tends to experience a significant decline. Meanwhile, the productivity has also decreased as well. Based on the calculation of the productivity level according to KEPMEN KP No.61/2014, the productivity level (2019) of purse seines that land their catch at TPI Ujungbatu Jepara is 4.45, meaning that the production produced in 2019 year is 4.45 tons per vessel 1 GT used.

The small pelagic resources in the waters of Kendari (FMA 714) that are dominant are mackerel scad (Decapterus macarellus) and Indian mackerel (Rastrelliger kanagurta). Fishing in these waters uses a mini purse seine, with the production of 2 species of fish has reached 38.2% of the total allowed catch FMA 714. Because of intensive use, management needed to preserve resources. The purpose of this study is to determine the decent size based on a comparison of length of the first capture (Lc) and the length of first mature (Lm), and prediction of spawning season. Data collection was conducted by researchers and assisted by enumerators monthly. The results showed that the size of the mackerel scad in between 17.5 - 30.5 cm FL (n = 3207 tails). The size of the Indian mackerel found between 18.5 - 26.5 cm FL (n = 2556). The length at first captured of both species was larger than the size at first matured (Lm> Lc) so that the decent size is 23 cm FL for mackerel scad and 22 cm FL for Indian mackerel. The prediction of the spawning season in May-August can be the basis for closing the area during the spawning season.

Red mud crab (Scylla olivacea) is an economic commodity that is traded into foreign countries such as China, Malaysia, and Singapore so that fishing activities are carried out intensively. Therefore, we need scientific information about the status of red mud crab fishery stock. Information about the natural mortality, fishing mortality, and the exploitation level of crabs can be used as the basis for crab fisheries management. The study was conducted for 2 (two) years, February to October 2017, and March to December 2018 using the survey method. The results showed that 36% of the crabs were caught below the 120 mm size as regulated in Regulation of the Minister of Marine Affairs and Fisheries No. 12 Year 2020. The carapace width of the first capture (CWc) is smaller than the size of the carapace width of the first gonad maturity (CWm). This shows that the crab has been captured before the first gonad maturity (CWc < CWm). The growth rate (K) is 0.65 per year with fishing mortality (F) higher than natural mortality (M). Exploitation level (E) 0.70 which indicates that the status fisheries of red mud crab in Mimika have been overexploited. Efforts need to be done by the Regional Government in collaboration with local community leaders in providing counseling and information about the size of red mud crabs that can be caught and reduce efforts to use crabs by as much as 40% of what is currently done.

Efforts need to be done by the Regional Government in collaboration with local community leaders in providing counseling and information about the size of red mud crabs that can be caught and reduce efforts to use crabs by as much as 40% of what is currently done. \u0000Keywords: status explotation, red mud crabs, Mimika, FMA 718","PeriodicalId":59401,"journal":{"name":"海洋渔业","volume":"9 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2020-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80236485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The blue swimming crab in the waters of Lancang Island is indicated as being overfished. Hence, the major challenge is managing its utilization in a proper manner. The purpose of this study is to explore the water's characteristics which is suitable for blue swimming crab fishing. Accordingly, the potential fishing ground around Lancang Island waters can be mapped spatially as an initial effort for species preservation. Geospatial analysis was applied to assess the physical parameters of the existing habitat. The results show that parameters such as MPT, TDS, brightness, phosphate, nitrate, depth and substrate types were remarkably suitable to support the growth of blue swimming crabs. Meanwhile, parameters such as salinity, DO, and temperature show lower quality which implied that the habitat is less suitable. However, the result of weighting and reclassification conclude that Lancang island waters is a decent habitat for blue swimming crab. Catch data show that 40% blue swimming crabs have small carapace size (7-11.83 cm) which is undersized and prohibited by law. Furthermore, about 68% of catch are quite light (30-147 gr) and the sex ratio of males to females was 1:2. It was also revealed that approximately 35% of female species were carrying eggs (BEF/barried female). Keywords: geospatial, fishing ground, suitability, Lancang Island, blue swimming crab.
