Catfish production from year to year has increased. Catfish production in Indonesia in 2013 reached 758,455 tons. The socialization of catfish hatchery using semi-artificial spawning is aimed at cultivating the community to increase seed yields and carry out catfish hatchery with semi-artificial spawning methods. The method used is the method of presentation and practice. Counseling on catfish spawning with semi-artificial techniques is very useful for groups of fish farmers, this is evident from the enthusiasm of the community who are enthusiastic in participating in the socialization from beginning to end. Abstrak Produksi ikan lele dari tahun ke tahun mengalami peningkatan. Produksi ikan lele di Indonesia pada Tahun 2013 mencapai 758.455 ton. Sosialisasi pembenihan ikan lele dengan menggunakkan pemijahan semi bauta bertujuan agar masyarakat pembudidaya dapat meningkatkan hasil benih dan melaksanakan pembenihan ikan lele  dengan metode pemijahan semi buatan. Metode yang digunakan adalah metode presentasi dan praktek. Penyuluhan tentang pemijahan ikan lele dengan teknik semi buatan sangat bermanfaat terhadap kelompok pembudidaya ikan, hal ini terbukti dari semangat masyarakat yang  antusias dalam mengikuti sosialisasi mulai dari awal sampai akhir.

Produksi ikan di dunia pada tahun 2018 diestimasikan telah mencapai sekitar 179 juta ton. Ikan sidat diperdagangkan dalam bentuk segar, hidup dan beku. Kerang lentera merupakan limbah yang dapat dimanfaatkan sebagai bahan pakan ikan, selain memiliki nutrisi tinggi, kerang lentera juga memiliki zat bioaktif di dalam tubuhnya.Tujuan penelitian ini adalah melihat respon ikan sidat dengan menggunakan pakan tambahan tepung kerrang lentera terhadap retensi protein ikan sidat. Penelitian ini menggunakkan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 ulangan. Penambahan tepung pedicle kerang lentera terbaik adalah 2% dari substitusi protein tepung ikan dilihat dari respon retensi protein yaitu 15,48%.

Overfishing and overcapacity is a problem for the sustainability of capture fisheries development. Indonesia has experienced overfishing or called overfishing and overcapacity or called excess fishing capacity. The west coast of the island of Sumatra has enormous fishing potential, both in territorial waters and in ZEE waters. The purpose of the study was to understand the trend of fluctuations in fish catches in the waters of West Sumatra. Assessing the effect of boat trips on fish catches in the waters of West Sumatra and providing basic information and management of fisheries in the waters of West Sumatra. The research material used is Catch per Unit Effort (CPUE) data. The overall data was monthly average data in 2019 with fishing ground areas in the Western waters of Sumatra, the Indian Ocean. The results showed the composition of catches in the waters of West Sumatra landed in PPN Sibolga there are three dominant types of fish, namely skipjack tuna 14.566.140 kg (49.90%), decapterus 6.404.470 kg (21.94%) and tunny 2.480.880 kg (8.50%), The dynamics of fish catches in PPN Sibolga in 2019 were highest in May at 3.945.143 kg and June was the lowest catch month of 1.093.292 kg and the average monthly catch in 2019 was 2.508.436 kg, the catch per business unit landed in PPN Sibolga in 2019 obtained the highest CPUE of 8.474 kg/trip (July 2019) and the lowest 1,755 kg/trip (June 2019).   ABSTRAK Overfishing dan overcapacity erupakan masalah keberlanjutan pembangunan perikanan tangkap. Indonesialah mengalami overfishing atau disebut penangkapan berlebih dan overcapacity atau disebut kelebihan kapasitas penangkapan.  Pantai Barat Pulau Sumatera memiliki potensi perikanan yang sangat besar, baik perairan teritorial maupun perairan ZEE. Tujuan dari penelitian adalah untuk memahami trend fluktuasi hasil tangkapan ikan di Perairan Barat Sumatera, mengkaji pengaruh trip kapal dengan hasil tangkapan ikan di Perairan Barat Sumatera dan memberikan informasi dasar dan pengelolaan perikanan di Perairan Barat Sumatera. Materi penelitian yang digunakan adalah data Catch per Unit Effort (CPUE). Keseluruhan data merupakan data rata-rata bulanan tahun 2019 dengan daerah fishing ground Perairan Barat Sumatera Samudera Hindia. Hasil penelitian menunjukkan komposisi hasil tangkapan di Perairan Barat Sumatera yang didaratkan di PPN Sibolga terdapat tiga jenis ikan yang dominan yaitu cakalang 14.566.140 kg (49,90%), layang 404.470 kg (21,94%) dan tongkol 2.480.880 kg (8,50%), Dinamika hasil tangkapan ikan di PPN Sibolga di tahun 2019  tertinggi terjadi pada bulan Mei sebesar 3.945.143 kg dan bulan Juni merupakan bulan hasil tangkapan terendah yaitu 1.093.292 kg dan rata-rata hasil tangkapan bulanan tahun 2019 adalah 2.508.436 kg, Hasil tangkapan per-unit usaha yang didaratkan di PPN Sibolga di tahun 2019 didapatkan CPUE tertinggi yaitu 8.474 kg/trip (Juli 2019) dan terendah 1.755 kg/trip (Juni 2019).

The western waters of Sumatera are one of the waters that have the potential of coastal and ocean resources. Oceanographic factors that can be related to high productivity in waters are SST (Sea Surface Temperature) and the distribution of chlorophyll concentration. Sibolga waters are geographically quite strategic, because they are located in the Indian Ocean, most of the catch is landed at the Sibolga Nusantara Fisheries Port. This Study aims to understand the trend of fluctuations in fish catches in the The Waters of Western Sumatera, to examine the effect of chlorophyll on fish catches in the waters of West Sumatera. Sea surface temperature and monthly chlorophyll-a concentrations were obtained from the result of the Aqua Modis months in 2021. Monthly data and data on fishing results were obtained from the Sibolga Nusantara Fisheries Port. The composition of catches in the western waters of Sumatera which landed at PPN Sibolga in 2021there three dominant fish species, namely Cakalang (Katsuwonis Pelamis) 11.655.768 Kg, Layang (Decapterus Sp) 4.589.147 (19,95%), Tembang (Sardinella sp) 2.421.523 (10,53%), the variation of fish catch per unit (CPUE) ;anded at PPN 2021. The Highest occurred in may at 3.809 kg/trip and the lowest occurred in November 1.521,58 kg/trip and the average monthly CPUE in 2021 was 5.105,88kg/trip. Monthly variations of sea surface temperature and chlorophyll-a in the waters of for 12 months (2021) the lowest temperature occurred in August, namely 26,88 0C while the highest temperature in February was 30,92 0C, the highest consentration was in May of 1,56 mg/m3 while the lowest occurred in March at 0,15 mg/m3.
