Abstract

Relating the annual oil-sardine landings to the rainfall data of June to August, it
is seen that there is a general correspondence in the oscillations between the two. It
appears that a mean daily rainfall range of 25 to 35 mm for June-July or 20 to 30 mm
for June-August periods may indicate the likelihood of a good recruitment of juveniles
to the commercial flsheryi whereas an amount outside the above range appears
to have a role in catch declension. It is seen that seasons of feeble or severe rainfall
coincide with extensive atresia in the ovaties, a phenomenon that may lead to reduction
in the spawning potential of the population. Theincursion of large number of
early juveniles into the nearshore wafers during July to September may also suggest
the prevalence of unfavourable conditions in the spawning/nursery ground^
