Abstract:
This study aims to determine the effectiveness of adding vitamin C and squid oil to
commercial feed for broodstock fish (Anabas testudineus Bloch) on the speed of gonadal
maturation and growth. The study was conducted for three months using a completely randomized
design with 4 treatments and 3 replications. The test fish were 10 each in each treatment hapa, the
treatment of feed A (Commercial feed =CF); B (CF + Vit c 2gr/kg; C (CF+ squid oil 3 ml/kg) and
D (CF+ Vitamin C 2 g/kg + Squid oil 3 ml/kg). Feed was given in the morning and evening
satiation for 30 days. The results showed that the commercial feed added with a combination of
vitamin C 2000mg/kg feed and squid oil as much as 3mg/kg feed (Treatment D) gave the best
gonadal maturity level. This is indicated by the average Gonadosomatic Index (GSI) of 4.20% and
the average HepatoSomatic Index (HSI) of 3.91%, higher than other treatments. Supported by
statistical test results showed very significant differences in somatic gonadal index, hepatosomatic
index, egg diameter and absolute fecundity. Meanwhile, growth and condition factors did not show significant differences. There is a tendency that if the dose of vitamin C and squid oil is increased again, it will be able to increase the gonad maturity of the broodstock of climbing
perch
