Genetic variation in the fish Liza parsia (Hamilton-Buchanan).

The role of aquaculture in augmenting fish production is now well recognized. The selection of productive strains for successful culture and subsequent domestication in different environmental conditions is faced as a major problem by the aquaculturist. A genetic approach to the problem has assumed great importance. Fish genetics has gained priority since, in other problems inherent with a aquaculturist viz., culture techniques, nutrition, controlled spawning, seed production and mortality control, considerable progress has been achieved. Moreover, knowledge of the genetic make-up and variability of the wild as well as farmed fish stocks is a prerequisite for the management of genetic resources for genetic improvement
