Biology of the exploited stock of mackerel tuna E. affinis (Cantor) off the south-west region of Ceylon
According to the statistical data published annually in the Administration Report of the Director of Fisheries, the bloodfish production in 1967-68 showed about 100% increase over a period of five years and the production figures for none of the other groups of fishes have exhibited a parallel to this. Furthermore, the bloodfish group ranks first in the order of production, having displaced the herring and sardine group which had been in the lead for over a decade. This indicates that increasing attention was paid on the production of this group of fishes, in the coastal waters of Sri Lanka.
