The population dynamics of fisheries stock enhancement, and its potential for generating benefits over and above those obtainable from optimal exploitation of wild stocks alone are poorly understood and highly controversial. I review pertinent knowledge of fish population biology, and extend the dynamic pool theory of fishing to stock enhancement by unpacking recruitment, incorporating regulati...

Decline in aquatic resource stocks, occurs for various reasons. Although regulations and measures have proven useful, they have failed to inhibit effectively the stock reduction trends. Iranian Fisheries Organization has carried out a great deal of investments and efforts concerning the enhancement of the Caspian Sea resource stocks through the restrictive regulations, and reproduction and rele...

The mechanisms that drive density dependence are rarely studied in the applied context of population management. We examined the potential for competition for food and shelter and the resulting demographic density dependence to influence how well populations of the eastern king prawn Penaeus plebejus Hess can recover following marine stock enhancement programmes in which captive-bred juveniles ...
