Abstract:
Rainbow sardines of the genus belonging
to the family Dueenaieriidae. are small pelagic fishes
forming a fairly good, though not abundant. seasonal fishery
all along the coasts of India inhabiting the coastal waters.
There have been some earlier reports on such individual
aspects as their systematic, distribution, abundance.
Ostecology and a few biological factors but no attempt has
been made towards a comprehensive study on this group. Two
species of rainbow sardines are known to occur in the Indian
seas and while a knowledge about their biology would be
useful from the fishery point of view. it was also thought
a study of their systematic position, especially regarding
the identity or the two species which had raised doubts
among earlier workers would lead to a better understanding
or the group as a whole. This thesis is mainly based on
studies during the period from April 1969 to march 1971 with
a continued investigation of fishhery aspects till December
1975. from the Gulf of manar: and the Palk Bay around
mandapam area. on the south-east coast of India. Thus the
work deals with the systemtics, biology and fishery of
rainbow sardines of Indian seas.
