Abstract
The purpose of this study was to analyze the effect of spawnprim hormone induction with different doses on gonadal maturity of lemeduk fish broodstock (Barbonymus schwanenfeldii). A completely randomized design (CRD) was used in this study with 4 treatments and 3 replications. Fish broodstock in group A (control) was not given any treatment, while fish broodstocks in groups B, C, and D were injected with spawnprim hormone at doses of 0.3 ml/kg body weight, 0.6 ml/kg body weight, dan 0.9 ml/kg body weight, respectively. The measured parameters were gonadal maturity level, broodstock weight gain, egg diameter, and fecundity. Data were analysed using one way analysis of variance (ANOVA). The result showed that the gonadal maturity level (GML) in groups B, C, and D (GML III and IV) was better than group A (GML I). Statistical analysis showed that the induction of spawnprim hormone on lemeduk broodstocks significantly affect (P<0,05) broodstock weight gain, egg diameter, and fecundity. The optimal dose of spawnprim hormon for lemeduk was 0,6 ml/kg body weight which recorded the average broodstock weight gain, egg diameter, and fecundity were 0.011 kg, 1.55 mm, and 102.15 eggs, respectively.
