Abstract

The small pelagic resources in the waters of Kendari (FMA 714) that are dominant are mackerel scad (Decapterus macarellus) and Indian mackerel (Rastrelliger kanagurta). Fishing in these waters uses a mini purse seine, with the production of 2 species of fish has reached 38.2% of the total allowed catch FMA 714. Because of intensive use, management needed to preserve resources. The purpose of this study is to determine the decent size based on a comparison of length of the first capture (Lc) and the length of first mature (Lm), and prediction of spawning season. Data collection was conducted by researchers and assisted by enumerators monthly. The results showed that the size of the mackerel scad in between 17.5 - 30.5 cm FL (n = 3207 tails). The size of the Indian mackerel found between 18.5 - 26.5 cm FL (n = 2556). The length at first captured of both species was larger than the size at first matured (Lm> Lc) so that the decent size is 23 cm FL for mackerel scad and 22 cm FL for Indian mackerel. The prediction of the spawning season in May-August can be the basis for closing the area during the spawning season.

Abstract

Red mud crab (Scylla olivacea) is an economic commodity that is traded into foreign countries such as China, Malaysia, and Singapore so that fishing activities are carried out intensively. Therefore, we need scientific information about the status of red mud crab fishery stock. Information about the natural mortality, fishing mortality, and the exploitation level of crabs can be used as the basis for crab fisheries management. The study was conducted for 2 (two) years, February to October 2017, and March to December 2018 using the survey method. The results showed that 36% of the crabs were caught below the 120 mm size as regulated in Regulation of the Minister of Marine Affairs and Fisheries No. 12 Year 2020. The carapace width of the first capture (CWc) is smaller than the size of the carapace width of the first gonad maturity (CWm). This shows that the crab has been captured before the first gonad maturity (CWc < CWm). The growth rate (K) is 0.65 per year with fishing mortality (F) higher than natural mortality (M). Exploitation level (E) 0.70 which indicates that the status fisheries of red mud crab in Mimika have been overexploited. Efforts need to be done by the Regional Government in collaboration with local community leaders in providing counseling and information about the size of red mud crabs that can be caught and reduce efforts to use crabs by as much as 40% of what is currently done.

Abstract

Penangkapan kepiting merah (Scylla olivacea) di Merauke berlangsung sangat intensif dan dikuatirkan akan mengancam kelestariannya. Untuk itu perlu pengelolaan yang didasarkan hasil kajian ilmiah. Dinamika populasi dan tingkat pemanfaatan merupakan informasi komponen penting dalam pengelolan perikanan secara efektif. Tujuan penelitian ini adalah untuk mengetahui dinamika populasi dan tingkat pemanfaatan kepiting merah di Merauke dan sekitarnya. Penelitian dilakukan selama 2 (dua) tahun yaitu Februari hingga Desember 2017 dan Maret hingga Desember 2018 dengan metode survey. Hasil penelitian menunjukkan struktur ukuran kepiting merah diatas 99 % berukuran dibawah 145 mm dan ukuran pertama kali tertangkap (CWc) adalah 110.52 mm (2017) dan 112,5 mm (2018). Pola pertumbuhan kepiting merah bersifat allometrik negatif dengan nisbah kelamin tidak seimbang antara jantan dan betina. Laju pertumbuhan (K) adalah 0,6 per tahun dengan tingkat kematian alamiah (M) lebih kecil daripada kematian karena penangkapan (F). Tingkat pemanfaatan (E) 0,68 menjadi indikasi telah terjadi overfishing dari nilai optimum penangkapan kepiting. Upaya pelestarian sumberdaya kepiting dapat dilakukan dengan mengurangi upaya penangkapan sebesar 36 % dari yang sudah dilakukan saat ini.The capture of red mud crabs (Scylla olivacea) in Merauke is very intensive and threat its sustainability. For this reason, management needs to be based on the results of scientific studies. Population dynamics and exploitation rates are information about important components in fisheries management effectively. The purpose of this study was to determine population dynamics and exploitation of red mud crabs in Merauke and its adjancent. The study was conducted for 2 (two) years, February to December 2017 and March to December 2018 with the survey method. The results showed that the structure of the size of red mud crabs above 99% was under 145 mm and the first size caught (CWc) was 110.52 mm (2017) and 112.5 mm (2018). The growth pattern of red mud crabs is allometric negatif with an unbalanced sex ratio between male and female. The growth rate (K) is 0.6 per year with a natural death rate (M) smaller than death due to arrest (F). The utilization rate (E) of 0.68 indicates an overfishing of the optimum value of crab capture. Efforts to preserve crab resources can be done by reducing fishing efforts by 36% from what has been done today.

Abstract

Udang dogol (Metapenaeus ensis) merupakan salah satu komoditas udang yang ditangkap menggunakan alat tangkap pukat dasar di perairan Meulaboh.  Diperlukan informasi ilmiah agar dapat dilakukan upaya pengelolaan sumberdaya udang dogol agar populasinya tetap terjaga dan lestari. Tujuan dari penelitian ini adalah mengetahui aspek biologi baik struktur ukuran, hubungan panjang karapas dengan bobot tubuh, rasio kelamin, tingkat kematangan gonad, perbandingan ukuran pertama kali tertangkap (Lc) dengan ukuran pertama kali matang gonad (Lm) serta tingkat pemanfaatannya di perairan Meulaboh. Penelitian dilakukan dari April sampai dengan Desember 2018 dengan sampel sebanyak 4.701 ekor baik jantan maupun betina. Struktur ukuran udang dogol 12 – 50 mm dengan dominan pada ukuran 30 mm dengan pola pertumbuhan allometrik negatif. Rasio kelamin udang seimbang antara jantan dengan betina dengan tingkat kematangan gonad tertinggi pada bulan September yang diprediksi sebagai puncak musim pemijahan. Ukuran pertama kali matang gonad (25,95 mm), udang dogol di perairan Meulaboh lebih dahulu matang gonad dari pada ukuran pertama kali tertangkap (28,10 mm) sehingga telah memberikan kontribusi di lingkungan (Lm > Lc). Tingkat pemanfaatan  (E) udang dogol masih rendah (0,35) dan ini menunjukkan masih dapat dilakukan upaya peningkatan penangkapan, dan didukung dengan tidak menggunakan alat tangkap pukat dasar sesuai dengan Permen KP Nomor 2 Tahun 2015.
