Abstract:
‘Biochemical genetics of selected commercially important
penaeid prawns‘ dloted was carried out by collecting
samples from different important fishing ceatres of India
and the practical work was carried out in the Research
Centre of CMFRI laboratories attached with those places.
On the whole, in crustacea little importance has been
given so far in finding out tin genetic characteristics of
different species, genetic variation within and between
species and ontogenetic variations in lobsters, prawns and
other crustaceans. Prawn is caunercially important group
where very little attention had been given so far to find
out the racial divergence which may exist in cufferent
species. with the increased foreign exchange earning and
consequent indiscriminate over exploitation of existing
resources of prawns resulting in depletion of the marine
rescurces, alternative ways and augmenting production has
become essential. In this connection genetic manipulation
of the broodstock will surely bring about the heterogenous
characters to multiply production. In order to understand
racial fragmentation of sane of the coumercially important
prawns such as Pengeus ggdicus and Parggenagsis sgliferg
the isozyme studies were carried out. Qatogenetic variation
of g. indicus showed stage specific electrophoretic variation.
Inter species variation studies was carried out for the
closely aligned Penaeus species
