EFFECT OF PARTIAL REPLACEMENT OF FISHMEAL WITH MORINGA LEAF POWDER ON GROWTH PERFORMANCE AND SURVIVAL OF PACIFIC WHITE SHRIMP, LITOPENAEUS VANNAMEI (BOONE, 1931)

The efficacy of partial replacement of fishmeal with Moringa oleifera leaf powder on growth performance and survival of Pacific white shrimp, Litopenaeus vannamei was the purpose of the study.During from March to May of 2021, the experiment was carried out in the Wet Laboratory, Department of Aquaculture, College of Fisheries Science, Kamdhenu University, Veraval for 60 days.The five experimental diets were formulated with 35% protein level.The supplementary diet was prepared and fed to L. vannamei at 10% body weight twice a day.The control diet was prepared without moringa leaf powder.The treatment diet contained 5, 10, 15, and 20% moringa leaf powder replacement.Fifteen L. vannamei post larvae (average weight 0.012 gm) were stocked per each of the 20 plastic tanks.L. vannamei's growth, survival rate, specific growth rates (SGR), feed conversion ratio (FCR) feed conversion efficiency (FCE) and protein efficiency ratio (PER) were assessed.According to the study's findings, the (T4) diet, which included 20% Moringa leaf powder protein had the highest mean weight gain, SGR, PER, FCE and lowest FCR.The control diet had the highest survival rate of 100%.Results of the current study revealed that the replacement of 20 % Moringa leaf powder significantly affected the weight gain, SGR, FCR, FCE and PER of L. vannamei.
