Abstract

Investigations were made on the ovarian maturation of banana prawn (Penaeus
merguiensis) held in a fixed hapa (2xlxlm) in inshore waters of Karwar bay. The
shrimps collected (ablated females and males in the ratio 2:1) were subjected to
experimental condition for a period of 10 days. The parameters such as salinity,
temperature, pH and primary productivity of the seawater at the site were monitored
regularly. Within 3-6 days after eyestalk ablation, 70% of the females
matured in the cage and spawned successfully in situ, thereby indicating the
possibility of induced ovarian maturation on commercial scale. Brood stock development
on commercial scale for other important candidate species of aquaculture
has been suggested.
