ENDOGENOUS NUTRIENT ABSORPTION AND LENGTH GROWTH OF LARVAE (D0-D3) UNDER DIFFERENT REARING TECHNIQUES IN SNAKEHEAD FISH (CHANNA STRIATA)

Abstract

A detailed study on the effects of hormones on process and larval growth from various breeding techniques will provide a better understanding of optimizing snakehead fish (Channa striata) seed production. The research aims to analyze endogenous nutrient absorption and length growth in larvae (D0-D3) from several different breeding techniques of snakehead fish (Channa striata). The study was conducted at the Freshwater Aquaculture Research Center Mandiangin, South Kalimantan. Three breeding techniques were employed: firstly, observation of naturally spawned larvae (breeding technique I) from 3 pairs of broodstock. Secondly, semi-artificial spawning using Ovaprim (breeding technique II) from 3 pairs of broodstock. Thirdly, continuation of the second treatment (rematuration) involving semi-artificial spawning using Oodev and Ovaprim (breeding technique III) from 3 pairs of broodstock.
