EFFECTS OF LIVE AND NON-LIVE FEED COMBINATIONS ON REARING SUCCESS OF MACROBRACHIUM ROSENBERGII LARVAE

An experiment was carried out at Department of Zoology and Aquaculture, Acharya Nagarjuna University, India from July to August 2010 to assess the effect of feed on larval survival of Macrobrachium rosenbergii. Three experiments viz. Artemia nauplii plus egg custard (E-1), Artemia nauplii only (E-2) and Egg custard only (E-3) were taken for the study each with two replicates. The experiment was conducted in fiber tanks with Macrobrachium rosenbergii larvae at a density of 100 no/ lt of water. Highest average survival rate (42%) was found in E-1 and the lowest survival rate was obtained in E-3. The results obtains that there is an immense potentiality for increasing freshwater prawn seed production through closed water system by using Artemia nauplii plus egg custard as feed.
