Spawning biology of prawns in relation to conservation of prawn resources

Abstract

The stagnation in prawn catch from the sea in recent years has raised anxious enquiries about the possibility of depletion of prawn stocks, and the remedial measures, if any, needed to increase marine prawn production. The frequent capture of large quantities of mature prawns with ripe ovaries by the trawlers has been alleged to be one of the possible causes of depletion of the prawn resources. The data collected by the CMFRI over the years were examined to throw light on the spawning habits of prawns and their management Implications.
