Abstract

Snakehead fish (Channa striata) is an economically important fish. In order to meet market needs, the current supply is more dependent on catches in public waters than on cultivation. One reason is the lack of seed production from hatcheries. The purpose of this study was to analyze the effect of using various doses of the ovaprim hormone on male and female snakehead fish to improve the spawning performance of snakehead fish. The study was an experiment using a 2 x 2 factorial completely randomized design (CRD) with 3 replications. The first factor was the dose of the male broodstock ovaprim hormone, with two dose levels of 0.5 mg/kg and 1.0 mg/kg, and the second factor was the dose of the female broodstock ovaprim hormone, 1.5 mg/kg and 3.0 mg/kg. The results showed that the latency time of snakehead fish in this study ranged from 22.6 to 31.2 hours. Hormone dose significantly affected the latency time of male and female broodstock, but no significant interaction. Fertilization rate 85.58 – 88.86% and egg hatchability 93.3 – 96.7%. These parameters of fertilization rate for males are significant, but females and the interaction show no significant differences. Then, there was no difference in egg hatchability between all treatments. They concluded that variations in ovaprim hormone doses only affected latency time and fertilization rate, and egg hatchability had no effect.
