Description Copepod is a natural food that has a small size in the nauplii stage and high nutritional value. Suitable as initial feed for marine fish larvae with small mouth openings. The research aims to know the harvest of copepods from Genus Acartia in mass culture to feed larvae in marine fish seed production. The research was conducted in 2020 at the Institute for Mariculture Research and Fisheries Extension, Gondol-Bali. The first study was divided into two steps to determine the growth pattern of copepods as a harvest reference in the second study, which was the culture in 3 jars of 10 L. The second was to determine the number of copepods harvested in mass culture as a feed supply. Culture using three fiber tanks volume 1,000 L, Inoculation was given copepodite stage with a density of 50 ind/L and given artificial feed and rearing until the density decreases. Based on the pattern of density growth from the first study, the copepod harvest in the second study began on the eighth day. The highest harvest of the nauplii stage was reached on the seventeenth day with 184.7 ind/L the copepodite stage of 4,4 ind/L. The results of copepod culture are not sufficiently used as the main feed for mass larval production and can only be used as a feed mixture to add nutritional larvae.
Copepod adalah pakan alami yang memiliki ukuran kecil pada stadia naupli dengan nilai nutrisi yang tinggi. Cocok sebagai pakan awal larva ikan laut dengan bukaan mulut kecil. Tujuan penelitian mengetahui hasil panen copepod dari Genus Acartia sebagai pakan alami pada kultur masal, untuk pakan larva pada produksi benih ikan laut. Penelitian dilakukan pada Tahun 2020, di Balai Besar Riset Budidaya Laut dan Penyuluhan Perikanan, Gondol-Bali. Penelitian dibagi menjadi 2 tahap, pertama adalah untuk mengetahui pola pertumbuhan copepod sebagai acuan panen pada penelitian ke dua. Copepod dipelihara pada 3 buah toples volume 10 L. Penelitian ke dua untuk mengetahui jumlah copepod yang dipanen pada kultur masal sebagai persedian pakan. Kultur menggunakan 3 bak fiber bervolume 1.000 L. Inokulasi yang diberikan stadia copepodit dengan kepadatan 50 ind/L. Copepod diberi pakan buatan dan dipelihara hingga kepadatan menurun. Berdasarkan pola pertumbuhan kepadatan copepod dari penelitian pertama maka panen copepod penelitian ke dua dimulai hari ke delapan. Hasil panen tertinggi stadia naupli dicapai hari ke tujuh belas dengan kepadatan 184,7 ind/L, stadia copepodit 4,4 ind/L. Hasil kulur copepod tidak cukup dipakai sebagai pakan utama pada produksi larva secara masal dan hanya dapat dipakai sebagai campuran pakan alami untuk menambah nilai nutrisi bagi larva.
