Culture Performance And Breeding Efficiency Of Jayanti Rohu Compared To Local Rohu (Labeo Rohita) Under Similar Field Conditions

Abstract

In this study, we compare the culture performance and breeding efficiency of two Rohu varieties—Jayanti Rohu and local Rohu—under controlled laboratory circumstances. So that we could compare growth, reproductive qualities, and early developmental characteristics between the two strains, we kept them in the same environment and used the same husbandry procedures. When compared to the local strain, Jayanti Rohu showed improved growth performance, suggesting that it would be better to cultivate in the field. Jayanti Rohu exhibited increased fecundity, a sign of better breeding efficiency, in relation to reproductive characteristics. Fertilized eggs and newly hatched spawn from Jayanti Rohu were quite small, however the spawn performed substantially better after hatching. When compared to local Rohu, the early stages of Jayanti Rohu larvae were more active and showed better growth during the initial rearing period. When compared to the local strain, the results indicate that Jayanti Rohu has superior growth potential, reproductive efficiency, and early larval vigor. All of these features make Jayanti Rohu a good candidate for use in field-based freshwater aquaculture systems that want to boost output and seed quality.
