Abstract :

To evaluate the effect of Mucuna pruriens (MP) seed enriched Artemia supplementation on reproductive performance in the spawners of Litopenaeus vannamei under laboratory conditions. The MP seed methanolic extracts enriched with Artemia at 100 ppm and 200 ppm fed to Viio harveyi infected male and female L.vannamei was conducted for 3 weeks. Reproductive assessment of V.harveyi infected male and female L.vannamei was achieved using assessing the male fecundity rate like sperm count, motility studies and female fecundity rate like egg size, egg count. The results are promising that normal male and female L.vannamei shrimps shows usual pattern of reproductive index whereas the V.harveyi infected shrimps showed drastic fecundity decline in terms of sperm and egg percentage. Shrimp on diet supplementation with MP enriched Artemia shows significant improvement in both male and female reproductive performance by providing viiosis resistance. The result suggested that treated group proven the potential to improve the performance of fecundity rate in the spawners.
