    • Abstract

       

      Daphnia similis Claus is a tropicopolitan and dominant species of temporary ponds of South India Laboratory cultures were made to study the longevity, preadult instars, egg production and growth using different concentrations of rice bran, an agro-industrial waste which is available readily and cheaply. Rice bran dissolved in pond water resulted not only in higher fecundity but also in an additional increase in size and as such rice bran may form an ideal nutrient medium for mass production of daphnids. Egg production is 6 times higher and growth is two fold greater in cultures with rice bran in pond water than in tap water with rice bran. From the present study it is hoped that, the use of rice bran in mass culture ofDaphnia similis will be profitable.
