Nair, K V Somasekharan (1974) A preliminary study on the length frequency of Pseudosciaena sina (Cuvier and Valenciennes) At Calicut during 1969-72. Indian Journal of Fisheries, 21 (2). pp. 330-338.
Length-frequency study made on Pseudosciaena sina (C & V) at Calicut during the years 1969-72 is presented in the paper. The probable growth rate of juveniles was observed to be 10-15 mm by analysing the boat-seine samples. The length-frequency graphs of trawl samples showed that in spite of prolonged spawning, recruitment of juveniles in to the fishery was in two peaks. The length of the fish at the completion of the first year was 135 mm and that at the completion of the second year was expected to be about 165 mm. The number of rings in the scales showed some correlation with the length of the fish. The fishery was constituted mainly by 0- and 1-year class individuals, though fishes probably belonging to higher age groups also occurred occasionally.
