Oil sardine
 
Description Studies on the spawning habits of fishes form an integral part of fishery
biological investigations. Nair (1959) published a detailed account on the
spawning habits and early life history of oil sardine, Sardinella longiceps Valenciennes.
Brief references on the spawning habits of oil sardine have also
been made by Homell and Nayudu (1924) and Chidambaram (1950). These
authors have drawn the conclusion that oil sardine have a prolonged spawning
season. During the course of investigations carried out on the biology of oil
sardine, observations were made on the occurrence of fish in various degrees of
spent condition and this indicated the possibility of oil sardine releasing eggs in
batches. So far there has been no published account to support this assumption.
In search of further support for this assumption studies on ova diameter were
conducted during the years 1960-62 at Mangalore, and the results obtained
thereon have been presented in this paper together with the minimum size at
first maturity.
