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

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.
THE CHARACTERISTICS OF SHRIMP FISHERIES IN KOTABARU, SOUTH KALIMANTAN, INDONESIA Harlyan, Ledhyane Ika; Setyohadi, Daduk; Tumulyadi, Agus; Sukandar, Sukandar; Maulana, Almaas Zain; Lathif, Adib Hisyam; Fanani, Zainal

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.

Abstract

Squid (Loligo spp.) belongs to the Cephalopoda group (squid, cuttlefish, octopus) and is one of the primary export commodities in the fisheries sector. National squid production increased by 5.5%, from 193,583.82 tons in 2020 to 204,156.28 tons in 2021. However, the potential sustainable catch in the Java Sea (WPPNRI 712, including the Madura Strait) has experienced an average annual decline of 1.9% from 2017 to 2022, dropping to 66,608 tons in 2022. This study aims to identify the species composition of squid, analyze length-weight relationships, and determine the mantle length at first gonad maturity (Lm). Data were obtained from fixed lift-net catches and analyzed in the Fisheries Exploitation Laboratory of Universitas Brawijaya. The results identified two main species: Photololigo duvaucelli (Indian squid) and Sepioteuthis lessoniana (bigfin reef squid). The composition of squid catches was 1.29% in purse seine operations and 2.91% in payang (seine net) operations. The length-weight relationship of both species exhibited a negative allometric growth pattern, where length growth outpaces weight gain. The sex ratio between males and females was balanced for both species. The mantle length at first gonad maturity (Lm) was greater than the mantle length at first capture (Lc), indicating that the catch was dominated by immature squid. These findings highlight the need for minimum catch size regulations to ensure the sustainability of squid resources in the Tuban waters.
