Destruction of non-edible biota due to bottom trawling: The ecological and conservation issues in a global context

Studies on the quantum of non-edible biota (NEB) discarded during the trawl fishing operations hardly exist in literature. The limited availability of baseline data on this specific area of research has resulted in an inadequate assessment of the ecological implications of plant and animal species caught and discarded during trawl operation. In this context, an attempt was made to document the marine faunal diversity and biomass of NEB destroyed and discarded by trawl operations along the Thoothukudi coast, Gulf of Mannar Marine Biosphere Reserve (GoMMBR), India
