A Review on the #Reproduction and Development in Fish by Chattopadhyay NR in BJSTR
Abstract
In order that survival of young be more than optimum, the
timing of spawning by the mature adult fish is so adjusted that
must be closely linked to the availability of maximum congenial
environment added by increased food availability of food for the
newly hatched young ones. The availability of food for the larvae
and juveniles of most temperate and cold water fish species varies
on a seasonal basis and following this fish are usually found to have
a discrete and selective spawning season so perfectly timed that
hatched out larvae will get readily available exogenous food from
nature for their further development. Thus, in many temperate
and cold water species, spawning is an annual event. Spawning
culminates a series of preparatory events during which the
gametes develop and the gonads increase in size. The annual cycle
of fishes generally categorized into three major phases:
