Abstract

Pterocaesio tile are generally caught by encircling gill nets using the schooling behavior of these species. The purpose of this study was analyze the biological reproduction of P. tile which induced sex ratio, gonadal maturity level, gonadal maturity index and size at first maturity. Data collection was carried out from October to December 2022. The data collection method was conducted using experimental fishing methods by operating unit gill net with mesh size of 1,75 and 2,0 inch. Fish samples of each actual fishing were measured total length and weight, dissected to determine sex, measured gonad weight and determined the level of gonadal maturity. The results showed that the sex ratio of male fish was higher than female fish. The GML phase is in phases I-V where the immature gonads are more dominant than the mature gonads, the GSI increases as GML increases. The size at first maturity for males is 20.6 cm and 18.6 cm for females.

Abstract

Leihitu waters are known as one of the areas with promising fisheries potential. However, the level of utilization of fisheries potential has not been managed evenly, even the level of welfare is still far from the expectations of the fishing community. This research will examine the extent to which the level of activity of utilization and management of fisheries resources in Leihitu as one of the fishermen's life support loci in terms of economic and cultural aspects based on ethnofisheries to improve Leihitu fisheries development and sustainable fisheries development strategies in Leihitu as an effort to increase productivity for local fishermen who carry out fishing business activities. This research was conducted for 6 months starting from October 2022-March 2023, In qualitative research, the researcher is the key instrument. Formulating a strategy for sustainable management of small-scale Madidihang tuna fishing resources based on ethnography was analyzed using SWOT analysis. Suitable strategies used, among others: conducting socialization and training to increase the capacity of fishermen, the importance of the role of historical, cultural, religious and artistic institutions and cooperation between communities and institutions. The strategy for sustainable management of Ethnography-based Small-Scale Madidihang Tuna fishermen resources in Leihitu District, namely conducting socialization and training, is to be able to produce not only limited to their own consumption and the production of fish.

Abstract

This study aims to determine the conditions of tuna utilization, and to analyze the monitoring of tuna fisheries resources in preventing IUU fishing in Seram Sea Waters. Methods This research uses descriptive methods including primary and secondary data. Primary data comes from tuna fishermen respondents, fisheries monitoring agencies using purposive sampling and in-depth interviews, secondary data through literature studies. The results showed that the average tuna production in West Seram Regency was 4.10%, yellowfin tuna was 0.20%, the average CPUE of handline tuna fishermen was 505.86 kg/month/unit. The institutional capacity of fisheries supervisors needs to be improved, even though the vessel compliance indicator reaches 136%. Fishery violations during 2016-2018 are: violations of fishing routes and areas, violations of VMS, violations of fishing permits, and prohibitions on fishing by foreign people or vessels.

Abstract

Various fishing gears that are operated in the coral reef waters of Western Seram Regency have their own selectivity, capture various species of fish, and have an impact on the damage to coral reef ecosystems. This study aims to determine the leading reef fishing gears in Western Seram District. The survey method is through observations and interviews with fishermen who conduct fishing activities of coral species. Respondents are determined by propulsive sampling, the selection of superior fishing gear is done by the scoring method. The results showed that the fishing gear classified into the line fishing gear was superior to other fishing gear, where the bottom trolling were superior. The less favored coral fishing equipment especially from the biological aspect needs attention to improve the method and design of the fishing gear.

Abstract

Penangkapan ikan yang tidak ramah lingkungan dapat berdampak pada sumber daya target, keragaman jenis maupun habitat. Ekosistem terumbu karang merupakan salah satu daerah penangkapan ikan yang sangat produktif dan sangat rentang terhadap aktivitas penangkapan ikan yang tidak ramah lingkungan. Oleh karena itu pemahaman terhadap prinsip penangkapan ikan ramah lingkungan sangat diperlukan bagi masyarakat nelayan yang melakukan aktivitas di ekosistem tersebut. Pelaksanaan pengabdian masyarakat ini merupakan sosialisasi prinsip penangkapan ikan karang berwawasan lingkungan telah dilaksanakan dengan baik. Para peserta dapat memahami prinsip-prinsip penangkapan ikan berwawasan lingkungan, dan diharapkan mereka akan mempraktekannya dalam desain dan metode penangkapan khususnya untuk menangkap ikan karang.

Abstract

Penelitian ini bertujuan untuk menilai selektivitas ukuran ikan Rastrelliger kanagurta (kembung lelaki) yang tertangkap dengan jaring insang lingkar ukuran mata jaring 5,1, 5,7 dan 6,3 cm. Percobaan penangkapan dilakukan di perairan Huamual Belakang Seram barat selama periode Oktober hingga Desember 2022. Ikan R kanagurta yang tertangkap diukur untuk menentukan panjang totalnya, dan distribusi frekuensi ukuran dihasilkan untuk setiap kategori ukuran mata jaring. Kurva selektivitas dianalisis dengan metode Kitahara menggunakan MS Excel. Hasil penelitian menunjukkan bahwa jaring insang lingkar dengan ukuran mata jaring 5,1 cm cenderung menangkap ikan R kanagurta yang lebih kecil, sehingga berpotensi menimbulkan bias dalam komposisi hasil tangkapan. Sebaliknya ukuran mata jaring 6,3 cm menunjukkan kemungkinan lebih besar untuk menangkap individu yang lebih besar dan memungkinkan ikan yang lebih kecil untuk meloloskan diri. Hal ini menunjukkan adanya strategi potensial untuk pengelolaan perikanan yang berfokus pada ukuran. Hasil penelitian ini mempunyai implikasi terhadap optimalisasi desain jaring insang lingkar untuk mendukung pengelolaan berkelanjutan di perairan Huamual Belakang Seram Barat. Kata kunci: berkelanjutan, indian mackerel, Kitahara, ukuran mata jaring

Abstract

Fish trap is used due to its good prospect, particularly for demersal fish and reef fish in Maluku. A challenge of trap fisheries is the capture of various species of fish, along with a narrow size variation in the captured fish. To reduce the species diversity in the catch and allow the escape of young fish, an escape gap is recommended. This study aims to analyze the effect of different escape gap sizes on the fish that escape and their chances of being caught or escaping relative to the dominant catch. The study was conducted from July to September 2021 in the waters of Eri Village, Nusaniwe District, Ambon City, Indonesia. The experimental fishing method was used in the field. The results indicated that the size of the escape gap had no effect on the number of fish that escaped through each escape gap. The 50% probability of Achanturus reversus escaping from the size 2.0 cm escape gap is in the total length range of 21-22 cm, while from a 3.0 cm escape gap is 24-25 cm. Keywords: Fish pot, escape gap, selectivity
