Abstract
Stock enhancement programs are conducted worldwide, with Japan leading in marine species. One of the target species for release in the country is black sea bream (Acanthopagrus schlegelii). A stock enhancement program for this fish in Hiroshima Bay has been conducted over the last 3 decades. The large number of juveniles released has contributed to fishery recovery.
Nevertheless, the augmentation of landings has led to several problems. The reduction of the market price of the species, an augmentation of the social pressure from oyster farmers demanding the protection of their interests, and losses of the genetic resources of the natural stock of black sea bream are some of the problems encountered.
In this chapter, we discuss the main constraints associated with the increase in the stock biomass.
In addition, some lessons learned and recommendations to be considered before and during the development of future stock enhancement programs are given.
