Induced maturation and spawning Of Indian penaeid prawns

Abstract

Using the technique of unilateral eyestalk ablation, Penaeus indicus, Penaeus monodon, Metapenaeus dobsoni and Parapenaeopsis stylifera have been induced to mature and spawn successfully under controlled conditions at the Narakkal Prawn Culture Laboratory of the Central Marine Fisheries Research Institute, Cochin. These prawns generally attained full maturity 10-16 days after eyestalk removal and spawned viable eggs that gave rise to normal, healthy larvae.
