Penelitian ini bertujuan untuk menganalisa perbedaan pemberian jenis pakan alami terhadap kelangsungan hidup larva ikan gurami. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan, yakni0pemberianpakan0alami0jenis0Artemia0sp., Daphnia sp.,0dan0Tubifex0sp.

ABSTRACT

The purpose of this study was to determine the effect of variations in different types of natural feed on the survival of gouramy larvae. This study used a completely randomized design (CRD) with 3 treatments, namely the provision of natural feed types of Artemia sp., Daphnia sp., And Tubifex sp. The results of the study of the main parameters of survival of gouramy larvae, the highest was produced by treatment of B (99.66%), followed by treatment C (98.22%), while the lowest was produced in treatment A (97.66%). The supporting parameters of the average percentage level of growth in the relative length of gouramy larvae ranged from 41.35% -79.56%. The highest was obtained in treatment C, followed by treatments A and B. Furthermore, the parameters of relative weight, the highest was obtained in treatment C of 644.18%, followed by treatment A of 486.21%, and treatment B of 210.35%. The results of statistical tests showed that the survival rate of larvae of gouramy had no significant effect (P <0.05), but for long and heavy growth had a very significant effect (P> 0.05). Media water quality during the study is still within the feasibility limit for gouramy larvae maintenance, where temperatures are 27-28,6?C, dissolved oxygen is between 3,16-5,5 mg / L, pH between 5,8-6,9 and ammonia between <0.01-0.16 mg / L.
