During maturation protein, lipid and carbohydrate contents of the ovaries increased while in the hepatopancreas the biochemical constituents decreased. In males, these changes were less pronounced. Tn the muscle tissue, no noticeable changes occurred in both the sexes.

This species attained 132 and 192 mm at the end of Ist and 2nd year of its life respectively. Fishery was supported mostly by zero and 1 y class individuals. The instantaneous rates of total, natural and fisihing mortalities were 4.35, 1.76 and 2.59 respectively. The exploitation rate and ratios were same (0.59).

The population density of S. cucullata was estimated to be 132.m(-2). Abundance of the oysters within different parts (lower, middle and upper) of the mid intertidal area (oyster zone) showed a significant difference. Average shell size (as dorsoventral measurement) was 39.5 mm. Sex ratio was calculated to be 0.86(n=595). Shell size and sex ratio did not differ significantly in the different parts of mid intertidal area.

P. aeruginosa was in high numbers in water, sediment and finfish samples during the postmonsoon season (January-March), not detectable during premonsoon (August and September) and early monsoon season (October) in water and sediment. Among finfish samples, it was not detected during late monsoon (December). It was isolated from sundried and salt cured fishes also.
