Multiple spawning in penaeid prawn, Parapenaeopsis stylifera in captivity

Abstract

Laboratory observations on the individual ripe and impregnated females of penaeid prawn Parapenaeopsis stylifera kept separately in the absence of males were made for 58 days. It was revealed that P. stylifera spawn at an interval of 15 to 25 days during the active breeding period. This interval between two spawning is delayed if females lay fertilized eggs in each event of spawning. Moulted females lay unfertilized eggs. The probable significance of the results obtained are discussed in the present paper
