Abstract

Biotic potential and environmental resistance of seven sgecles of bivalves inhabiting Mangalore coast have been quantified from data gathered during the past 15 years. The species examined are the oysters Crassostrea madrasensis (Preston), Saccostrea cucullata (Von Born), the clams Meretrix casta (Hanley), Katelysia opima (Gmelin) Villorita cyprinoides (Gray), Donax incarnatus (Gmelin) and the mussel Perna viridis (Linnaeus) Components of blotic potential are described in terms of distribution and density, growth survival, longevity, age, size at first maturity and production. Environmental resistance was delineated by examining spawning', settlement, survival crowding, overgrowth, fouling and mortality. Data on these aspects have been presented and discussed.
