Abstract

Observations made on the fishery and biology of Cynoglossus dubius Day at Calicut during 1967-1972 showed that 1969 was the best year, and 1972 the worst for this fishery. The length range varied from below 5 cm to 40-40.9 cm (total length); the exceptionally smallest and largest records were, however, 2.2 cm and 41.4 cm respectively. Scales showed growth rings. The first ring was seen in fish of about 18 cm total length. Up to ten or even more rings seem to occur in the largest fish. The spawning season is roughly the same as, or a little later than that of the Malabar sole, C. macrostomus (Norman).
