Abstract

The incidence of dolphins in the gill nets were found to be more during the colder months of the year from October to February. Stenella longirostns contributed 52.9% of the dolphins landed followed by Tursiops adimcus which formed 32.7%. Delphinus delphis tropicalis and Sousa chinensis were the other two species that occurred in the nets
