PENAMBAHAN MULTI ASAM AMINO PADA MEDIA PEMELIHARAAN LARVA RAJUNGAN Portunus pelagicus UNTUK LAJU PERCEPATAN METAMORFOSIS STADIA ZOEA HINGGA MEGALOPA

Abstract

The addition of multi-amino acids to the culture media for Portunus pelagicus crab larvae accelerates the metamorphosis rate from the zoea to megalopa stages. The research aims to examine the effect of adding multiple amino acids to the rearing media and determine the best dosage on the rate of acceleration of metamorphosis (stage transfer) of P. pelagicus crab larvae from zoea to megalopa stages. Test samples are taken daily to see the development of larvae or larval stage index. The test animals used in this research were zoea-1 stage crab larvae stocked at 100 individuals/L density. The container used in this research was a black plastic basin with a water volume of 30 liters. Treatment doses of amino acids were 0, 150, 200, and 250 ppm with 3 repetitions each. The research results show that administering multi-amino acids in the rearing media can accelerate the transfer rate of crab larvae stages. The fastest rate of acceleration of metamorphosis from zoea to megalopa was produced at a treatment dose of 250 ppm for 10 days, and the longest was produced at a dose of 0 ppm for 13 days. Stage transfer between sub-zoea takes 2-3 days for metamorphosis, and zoea to megalopa takes 10-13 days.Penambahan multi asam amino pada media pemeliharaan larva rajungan Portunus pelagicus untuk laju percepatan metamorfosis stadia zoea hingga megalopa.

Penelitian ini bertujuan untuk mengkaji pengaruh penambahan multi asam amino terhadap laju percepatan metamorphosis (perpindahan stadia) larva rajungan P.pelagicus. Pengambilan sampel uji dilakukan setiap hari untuk melihat perkembangan larva atau larva stage indeks. Hewan uji yang digunakan pada penelitan ini ialah larva rajungan stadia zoea-1 yang ditebar dengan kepadatan 100 ekor/L. Wadah yang digunakan pada penelitian ini ialah baskom plastic berwarna hitam dengan volume air 30 liter dan penelitian ini menggunakan  perlakuan dosis asam amino dengan masing-masing 3 ulangan. Keempat dosis tersebut ialah 0, 150, 200 dan 250 ppm. Hasil penelitian ini menunjukkan bahwa dengan pemberian multi asam amino dapat mempercepat laju perpindahan stadia larva rajungan. Laju percepatan metamorphosis tercepat dihasilkan pada dosis perlakuan  250 ppm selama 10 hari dan terlama dihasilkan pada dosis 0 ppm selama 13 hari
