Environmental controls for induced maturation

Abstract

Reproduction in cultured finfishes is usually restricted to a specific period of the year when erivironmental conditions are favourable, the success of marine and brackishwater finfish breeding primarily depends on the availability of heaIthy breeders in sufficient numbers for use in induced breeding and thereby leading to large scale seed production in India, in order to meet the growing demand for the seed of cultivable marine and brackishwater finfish for aquaculture practices, mass production of seed by induced bre6ding is an essential prerequisite. It is imperative to maintain brood stocks in an environment which is conducive to them and one that promotes gonada1 maturation. Many of the maj or current problems in marine and brackishwater fihfish breeding relate to nutrition, reproduction and environmental requirements and hence the need for better understanding and control of these factors (Lam, 1983)
