Induced Breeding Of Labeo Rohita With “Ovatide”

Abstract

Labeo rohita commonly known as Rohu, is a prominent freshwater fish in South Asian aquaculture due to its high commercial value and nutritional benefits. Aquaculture uses induced breeding as a technique to stimulate fish to spawn in a controlled environment. The technique involves the administration of hormones that trigger the fish’s reproductive system to undergo final maturation, ovulation, and spawning. We calibrated this hormone Ovatide usage based on the weight and maturity stage of the broodstock. The ovatide significantly enhances the ovulation rate and egg quality, with spawning initiated within 12 to 24 hours of injection. Depending on the environmental conditions, the breeding rate reaches 80%, and the fertilization rate is around 90% enhanced compared to the other methods.
