Description The investigations on various hydro-biological parameters which influence the condition factor,
spawning and the resource characteristics of the edible oyster Crassostrea madrasensls around Tuticorin
have been conducted in three habitats of oyster beds, namely coastal (Tuticorin Bay), mangrove (Korampallam Creek) and estuarine (Punnakayal) areas. Observations on the stages of maturity, spawning
and condition of oysters in the three habitats have been made and a correlation of the above biological
aspects of the oysters with the environmental factors have been attempted. A direct correlation has
been observed between the biological aspects of oysters and the productivity parameters of the habitat.
The water temperature also showed a direct relationship with the condition factor of the oysters. The
mean value of the condition factor of the oysters were found to be at the optimum level during April
when productivity parameters were observed to be at higher level. The chemical factors especially
the nutrients such as nitrates and phosphates showed an indirect relationship with maturity and condition
of the oysters. Among the different habitats, the mangrove area registered higher productivity
rates which has a well defined relation with the condition of oysters.
