Abstract

The various characteristics of catches and fishing gear provide distinct advantages for fishermen, but these characteristics can cause other problems, namely pressure on stock availability caused by an increase in the number of catches and the use of various types of fishing gear and the efficiency provided. There needs to be good management to handle this. The purpose of this research is to find out the clusterization (grouping) of fishing areas based on the catch and the type of fishing gear in which the results of this study are used as a reference in sustainable fisheries management. This research uses descriptive methods and case studies at PPP Bulu. The analytical method used is the Shannon-Wienner index of diversity (S-W,H'), Margalef richness (R') and clusterization. Clusterization was analyzed using the Hierachical Cluster Analysis (HCA) method to obtain the Euclidean distance. The results showed that the value of diversity has a range of 0-2 and the value of wealth has a range of 1-10. The results of the clusterization show that there are 3 clusters of fishing areas formed based on the catch, while no clusters of fishing areas are formed based on the type of fishing gear operated.

Abstract

Multispecies demersal fisheries management in Brondong waters have been managed by conventional single-species approach for determining catch quota or annual allowable biological catch (ABC). This might be impractical since a multispecies fishery should be managed by a multispecies fisheries management approach. The feedback harvest control rule (HCR) is a harvest control rule that has been validated and might be applied for a multispecies fishery. The aim of this study is to compare the conventional single-species approach and the feedback HCR in order to estimate the annual ABC. In this study, the annual ABC was calculated by applying two HCRs, the conventional single-species approach that applying the Schaefer surplus production model into the catch and effort of the dominant demersal fisheries data series of 2011 – 2020. The results showed that the Schaefer model provided the annual ABC higher than the feedback HCR estimation. Therefore, it was safe to apply the feedback HCR than the Schaefer model to determine the annual ABC. Under data-limited conditions, the feedback HCR might be an option to manage multispecies fisheries.

Abstract

Shark and ray fishery issues raised in Indonesia as some species have been listed in the IUCN red list. In relation to the conservation of some shark and ray species, critical information is required related to several biological aspects to assure its fishery sustainability. This study was conducted in Brondong Fishing Port in February – March 2020. Length, weight, and maturity level data were collected from 272 shark individuals and 267 ray individuals. Several analyses were performed, such as length-weight relationship analysis, sex ratios, and maturity level analysis. The study found 18 species listed in the IUCN red list were dominantly composed of Carcharias taurus and Dasyatis kuhlii. Both species have negative allometric, while the sex ratios showed that the ratio of the number of male and female individuals for shark and ray are 1:5 and 1:2, respectively. The maturity level of male individuals for Carcharias taurus pointed that 33% full calcification (FC), 17% non-full calcification (NFC), and 50% non-calcification (NC), while for Dasyatis kuhlii resulted that 66% FC, 28% NFC, and 6% NC. It is concluded that the biological aspects of the dominant species indicated that most individuals were in a critical state, thus it is required to monitor and control their fishing pressures.

Abstract

Fisheries data statistics play an important role in fisheries management. The data collection might be provided in landing sites. However, not all landing sites can provide the fisheries data. Kandangsemangkon small landing site is an unreported landing site that land various economically important species, one of species is Trevally fishery. The purposes of this study were to identify the species landed, determine the categorization of species supporting the landed trevally fishery and determine the trevally fishing area and the volume of trevally production that was not recorded or reported at Kandangsemangkon Small Landing Site. The data collection method of this study is by descriptive survey method, which are by taking primary and secondary data. The primary data collection was carried out by interviewing fishermen regarding the species of catch landed and the trevally fishing area, and observing the research location. The secondary data used was the production data of trevally landed at Brondong Archipelago Fishing Port. The results of this study are there were types of target species, secondary species, primary species and there is not endangered, threatened and protected species were found. The trevally fishing grounds are generally in WPPNRI 712 and 713. The volume of unrecorded and unreported production was 46.70%, and did not contribute to the fisheries statistics of Lamongan, East Java.

Abstract

The fourfinger threadfin, Eleutheronema tetradactylum is one of economic demersal species in Indonesia. Information of its biology was needed to ensure the sustainable fisheries management of this species. This study aimsto estimate the lengthweight relationship and condition factor of E. tetradactylum landed in Sedati, Sidoarjo, East Java. In total, 649 samples were randomly collected from Sedati Fishing Base during the study. The results indicated that E. tetradactylum has negative allometric growth pattern (b = 2.8, p<0.05), means the growth of length was faster than weight. In addition, the average value of relative weight condition factor (kn) was 1.01, which is greater than or equal to 1, means E. tetradactylum live in good growth conditions. This finding contributes to managing E. tetradactylum fishery in the north Java waters, especially in East Java. As this study was conducted from unsexed samples, future research with focuse on sexed samples is suggested to give more comprehensive result.

Abstract

The shrimp fishery in Kotabaru, South Kalimantan, is a small-scale fishery that supplies raw materials to PT. Sekar Laut, Tbk, a company specializing in shrimp cracker production for the global market. Despite its significance, limited research has been conducted on the sustainability of this fishery. This study aims to analyze the key characteristics of the shrimp fishery in Kotabaru waters. Data were collected from January to August 2024 in Kotabaru, South Kalimantan, and subjected to various analyses, including species composition, length-weight relationships for several shrimp species, and identification of shrimp fishing grounds. The results reveal that banana shrimp and yellow shrimp are the predominant species within the catch, both exhibiting negative allometric growth patterns. The fishery’s most productive fishing location is identified in Pantai Village, highlighting this area as a potential focus for sustainable management initiatives. These findings underscore the need for ongoing monitoring and targeted management practices to promote the long-term sustainability of the shrimp fishery in Kotabaru.
