FIRST REPORT ON OPHTHALMIC DELIVERY OF A GONADOTROPHIC HORMONE FOR INDUCED BREEDING IN IUCN ENLISTED (LC) SPIRALOTHELPHUSA HYDRODROMA

Intra-ocular delivery a synthetic gonadotrophic hormone (WOVA-FH) was administered to a freshwater crab for its first time and the effect of the drug was assessed based on growth, survival, reproductive and biochemical indices. 100% Survival Rate was recorded for male and female crabs after 10 days of dosage with reduced Heart Index and fairly increased Daily Growth Rate (g) compared to their controls (0.30 ± 0.10/0.16 ± 0.09 and 0.06 ± 0.06/0.05 ± 0.008). Significant increase in ovarian index (1.4 ± 0.06/0.15 ± 0.02) and slight increase in testicular index (1.29 ± 0.10/ 1.08 ± 0.06) both positively correlated with its protein, carbohydrate and lipid contents recorded against control. The somatic biochemical indices reduced abruptly after stimulation against control i.e., 105.0 ± 1.0/138.3 ± 1.1, 3.9 ± 0.1/4.43 ± 1.20, 87.4 ± 1.0/91.52 ± 1.2 and 129.0 ± 1.0/141.2 ± 1.2, 5.1 ± 1.0/5.6 ± 1.12, 83.5 ± 1.0/87.5 ± 1.1 are the protein, carbohydrate and lipid vales in male and female/control.
