A study of the Variations in the rate of growth of economically valuable
fishes forms an important aspect of their biology. In the Indian oil sardine,
Sardinella longiceps, this has not received due attention so far, although brief
references to growth-variations have been made by some of the previous workers.
Homell and Nayudu (1924) stated that growth is tremendous in the first
year and negligible subsequently. Devanesan (1943), from a study of the growth
rings on the scales, gave the sizes of the different year-classes. Chidambaram
(1950) has given the maximum sizes and size-progression of the age-groups in
successive years. Nair (1953) has noted that age-groups in the fishery "showed
variations in their rate of growth" and subsequently stated (Nair, 1959) that
length-frequency data "show differential rate of growth during the first year
(Nair, 1953)". Apart frpm these nothing substantial is published hitherto on
variations in the growth of this fish. Hence the present paper dealing with
differences in its growth rate in successive years of its life in the fishery, those
within each season and in between seasons, as well as different phases of its
life-history may be of interest. The investigations were made during 1961-1964
at Cannanore, one of the important oil sardine fishing centres in the Malabar
zone of the south-west coast of India.
