Abstract

This study investigates the effectiveness of combining the low-tide transect method with the use of crab pots to map the spatial distribution of mangrove crabs (Scylla spp.) in the Kalangan River, Central Tapanuli. Mangrove crabs are ecologically and economically significant species in coastal environments, yet limited data exist on their spatial population dynamics. An exploratory survey was conducted over a period of one month across three transect sites using standardised 1×1 meter PVC frames and systematically placed crab pots. Observations included species composition, carapace size, and habitat substrate type. The findings revealed that Scylla olivacea dominated the catch (68%), with the highest density recorded at transect 2 (0.86 individuals/m2), characterised by fine, sandy-muddy substrate and moderate mangrove cover. Transect 1 showed the lowest density (0.63 individuals/m²), likely due to degraded mangrove vegetation and coarse sandy substrate. A positive correlation was observed between tidal depth and catch abundance. The results suggest that this integrated method offers a reliable baseline for assessing mangrove crab populations and can inform sustainable coastal resource management practices.

Abstract

Continuous and uncontrolled fishing of red snapper will cause fish stocks to degrade, while there is no recruitment process and if caught without good management. Therefore, it is necessary to study the estimation of the sustainable potential of red snapper. The purpose of this study was to calculate Catch Per Unit Effort (CPUE) and assess the value of Maximum Sustainable Yield (MSY) and Total Allowable Catch (TAC/JTB) of red snapper. The research was conducted at Sibolga VAT with survey data collection method, while the surplus production method with Schaefer model. The results showed that the standardized CPUE value in 2018 was 0.060 tons/trip, in 2019 it decreased to 0.037 tons/trip, in 2020 it decreased to 0.029 tons/trip, in 2021 it increased to 0.041 tons/trip, and in 2022 it increased to 0.060 tons/trip, then a decrease occurred again in 2023 which was 0.055 tons/trip. The overall CMSY value calculated using the Scheafer model was 122.2 tons, so it can be concluded that the fishing status is fully exploited and overfished. While the FMSY value is obtained at 3201 trips, where the status is overfished and fully exploited because the fishing effort each year is above the FMSY value. The total allowable catch (TAC/JTB) is 97.8 tons.

Abstract

Girian Bawah Village fishermen use handlines in tuna fishing activities. This study aims to determine the efficiency of fishing time while fishing on the number of tuna handline catches. This study uses catch data with fishing areas in the Maluku Sea during October-November 2022 using the fishing experiment method in a 3-repeat time period, namely morning (05.00 - 09.59), afternoon (10.00 - 14.59) and evening (15.00 - 19.59), then analyzed descriptively quantitatively. Data analysis used statistical tests (Normality Test, Homogeneity Test, ANOVA Test and BNT Test) to see the best time for catching. The results of the normality test obtained normal values, the results of the homogeneity test obtained homogeneous values, the results of the correlation test, have a strong relationship. The results of the ANOVA test show that there is an influence between fishing time and the number and weight of catches. The results of the BNT test, obtained the best time for catching using a tuna handline is the time group 05.00-09.59 WITA or morning time.

Abstract

The purse seine fishery in Sibolga plays a vital role in fish production but faces challenges regarding compliance with licensed fishing ground regulations. Non-compliance, driven by economic pressure and declining fish stocks, threatens resource sustainability and fishermen’s welfare. This study aimed to analyze fishermen’s perceptions and compliance levels regarding the use of licensed fishing areas and their relationship to regulatory enforcement. The research was conducted from January-March 2024 at Sibolga Archipelago Fishing Port, North Sumatra, one of the main landing bases for purse seine vessels. Data were collected from 115 respondents, consisting of vessel captains and mates, using structured questionnaires and direct interviews. Observations and secondary data from fisheries institutions supported the primary data. Data were analyzed using descriptive statistics and the non-parametric Kruskal–Wallis test to determine differences in perceptions and compliance among fishing groups categorized by vessel tonnage and fishing zones. The results showed that fishermen’s perceptions of potential fishing grounds and fish resource availability were relatively uniform across groups, indicating a shared view that fishing effort continues to expand to secure catches. In contrast, perceptions of VMS usage differed significantly, with the 30–100 GT small pelagic purse seine group acknowledging its role in detecting violations. Compliance levels also varied, with the 30–100 GT small pelagic purse seine operating in <12-mile zones showing the lowest compliance. It is concluded that stricter enforcement, effective monitoring, and targeted empowerment programs are necessary to enhance compliance and ensure sustainable fisheries management in Sibolga.

Abstract

Penangkapan ikan teri yang terus menerus dilakukan secara intens oleh nelayan bagan di Sibolga dan Tapanuli Tengah dengan tanpa adanya pengelolaan dan pengaturan yang baik, akan menimbulkan akibat yang kurang baik kedepannya khususnya pada keberlanjutan sumberdaya perikanan ikan teri itu sendiri. Salah satu solusi yang dapat diberikan untuk mengatasi timbulnya permasalahan seperti yang disebutkan di atas adalah dengan melakukan pengelolaan terhadap sumberdaya ikan teri, sehingga kedepannya tetap berkelanjutan. Salah satu métode yang paling banyak digunakan untuk pengelolaan adalah menggunakan métode EAFM (Ecosystem Approach to Fisheries Management). Mengevaluasi status pengelolaan dan merumuskan tindakan aksi pengelolaan untuk sumberdaya ikan teri di Sibolga dan Tapanuli Tengah menjadi tujuan yang ingin dicapai. Kelurahan Hajoran, Kelurahan Muara Nibong, Kelurahan Lubuk Tukko, dan Desa Mela I merupakan lokasi penelitian berlangsung. Pengumpulan data dilakukan menggunakan teknik survei secara langsung di lapangan. Baik purposive maupun accidental sampling adalah metode pengambilan sampel. Metode EAFM digunakan untuk analisis. Pengelolaan sumber daya ikan teri yang bergantung pada alat tangkap bagan tancap di Sibolga dan Tapanuli Tengah termasuk dalam kategori "baik", yang berarti bahwa mereka harus digunakan dengan hati-hati. Tindakan pengelolaan harus diperbaiki untuk beberapa nilai indikator, seperti penurunan tren CPUE. Untuk mengontrol upaya penangkapan bagan tancap, disarankan untuk mengatur jumlah alat tangkap dan membatasi kuota penangkapan. Karena banyaknya yuwana yang tertangkap dan pecahnya jarak, perlu diterapkan sistem buka tutup (open close system) pada musim tertentu dan mengatur jarak penempatan bagan tancap.
