Subject Fishery biology
 
Description Opisthopterus tardoore is a small sized fish commonly growing to about 170 mm
to 190 mm in length, the maximum size recorded during the course of the present work being
216 mm. As regards its distribution, Day (1899) mentions it " from Gwadur in Bellochistan
and Sind, through the seas of India to the Malaya Archipelago". The Opisthopterus tardoore
fishery at Karwar (N. Kanara) is restricted to a short period. It commences in May and endeither
in September or early October. The main fishery season extends from June to September
with a peak generally falling in the month of July. The most important gear used for
the capture of this species is the shore seine. It is also fished by gill net, cast net and drag net
The preseat paper deals with the observations on length frequency distribution of this species
and incorporates the results of investigation carried out at Karwar from 1956 to 1960. Brief
notes on length-weight relationship and food analysis of this species are also given. Details regarding
maturity, spawaing and morphometric analysis of the stock of this species in the
Kanara coast have been given separately elsewhere.
