Abstract

ABSTRACTTransshipment in longline fisheries is a common activity  at Nizam Zachman Jakarta  fishing port.  Publication  of  PERMEN  KP  No.  57  of  2014  causing  strong  protests  among  actors  and unloading included in PPS over Nizam Zahman.  The purpose of this research  are  to identify the movement patterns of longline vessels through VMS data  and to  estimate longline target catch by transshipment. This research was applied descriptive method.   Primary data was derived from the VMS tracking data and interviews. Secondary data were obtained from 276 loading and unloading activities longline tuna catches. The results of this study indicated that the movement of the ship only  accommodate  the  catch  can  be  clearly  identified  by  VMS.  Transshipment  activity,  mostly happened  to target catches which  reaching  62% with bigeye tunadominantly  92.61%. On bycatch, there  were three  dominant  species,  that  were  mackerel scad,  mackerel tuna  and southern bluefin tuna. Fresh conditions dominate activity over the load by 89%, ie 46% of the quality of export  whole quality and 43% reject  quality. Fresh condition consists of six species, bigeye tuna (2,408,999 kg), yellowfin tuna (970,186 kg), Swordfish (47,774 Kg), southern bluefin tuna (4,435 kg), marlin (962 kg)  and  albacore  (39  kg).  Transshipment  at  Nizam  Zachman  Jakarta  fishing  port  dominated  by fishing vessel measured 61-100 GT and < 50 days long trip.  It  shows that there was correlation between transshipment activity and fresh tuna industry.Keywords: catch composition, transshipment, tuna longline, VMS dataABSTRAKAlih muat hasil tangkapan dalam perikanan  longline  umum terjadi di PPS Nizam Zachman Jakarta.

Abstract

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.

Abstract

The fishing activity of eel fish for daily consumption has been carried out by the local people in the Kaur Regency. However, the data related to the species of the eel fish, catch structure, and the eel fishing ground in Kaur Regency is still very limited, especially in the Luas River and Kinal River. Data and information on the eel fisheries in Kaur Regency are expected to be used as basic information in sustainable use of the eel fisheries. This study aims to analyze the catch composition of the eel caught and to determine the eel fishing ground for both rivers. Experimental fishing using eel hand line was carried out from June to August 2021 in Luas River and Kinal River, Kaur Regency, Bengkulu. The composition of catch eel only one species of eel, namely Anguilla marmorata with ano-dorsal ratio of 14.05-18.23%. The A. marmorata eel was caught at every station in both rivers. The Shannon – Wiener (H') diversity index of the catches at all stations in both rivers was relatively similar, ranging from 1.14 to 1.69. The eel fishing grounds in the Luas river and Kinal river are divided into 3 areas: estuary, mid- part of the rivers, and upstream area. Keywords: Anguilla marmorata, catch composition, eel, Kinal river, Luas river.

Abstract

Information on the catch composition and catchable size of lobsters in Lebak waters remains limited, posing challenges for effective fisheries management. This study aims to assess the technical performance of the lobster fishery and analyse catch composition. Data on technical performance were collected through interviews with fishers and lobster collectors using random sampling, while a census approach was applied to measure carapace length and weight for 589 lobsters. A descriptive quantitative analysis was conducted to evaluate the length-weight relationship of lobsters. The findings indicate that fishers predominantly use polyamide monofilament gillnets with a mesh size of 3.5–4.0 inches, operating traditional outrigger boats of 2–3 GT and 7 GT for single-day fishing trips in Lebak waters. Panulirus homarus was the dominant species in the catch. The sex ratio of lobsters was imbalanced, and their growth pattern exhibited negative allometry (b < 3). An assessment of catch sizes against the standards set by PERMEN-KP No. 16/2022 revealed a high proportion of undersized lobsters in the Binuangeun Estuary, including P. penicillatus (78–83%), P. homarus (80–100%), P. ornatus (23%), P. longipes (90–100%), and P. versicolor (65–100%). Similarly, in the Cibareno Estuary, the percentages of undersized lobsters were P. penicillatus (84–100%), P. homarus (98%), P. ornatus (0%), P. longipes (100%), and P. versicolor (92%). These findings highlight the need for stricter management measures to ensure sustainable lobster fisheries in the region. Keywords: catchable, Lebak Banten waters, length weight, lobster, sex ratio
