Role of nutrition in broodstock management - Prawns

For successful hatchery production of prawn seed a \nsteady supply of spawners of desired species of prawns at \nthe proper time is a necessary prerequisite. The uncertainity \nof procuring spawners from the wild has stimulated worldwide \ninterest in the efforts to induce prawns to mature under \ncontrolled conditions. A successful technology for inducing \nmaturity and spawning of penaeid prawns has been developed \nat the Marine Prawn Hatchery Laboratory (MPHL) of Central \nMarine Fisheries Research Institute by employing the method \nof unilateral eyestalk ablation. Using this technique many \ncommercially important species of penaeid prawns (Penaeus \nmonodon, Pehaeus indicus, Penaeus semisulcatus, Metapenaeus \ndobsoni, Metapenaeus monoceros and Parapenaeopsis stylifera) \nhave been induced to mature and spawn dn captivity (Muthu \nand Laxminarayana, 1977, 1979, 1982; Laxminarayana and \nSasidharan, 1983).
