Box 3160, Carenage Post Office, Trinidad & Tobago, West Indies e-mail: lleelum@ima.gov.tt Abstract. A study was conducted on the incidental capture of sea turtles in the artisanal gillnet fishery in Trinidad and Tobago. The objectives were (i) to determine the fishing effort; (ii) to identify gillnet fishing areas and seasonality of turtle capture; (iii) to quantify the numbers, species and fate of captured turtles; (iv) to solicit the opinions of fishermen on turtle capture and; (v) to recommend measures to reduce sea turtle bycatch, if necessary. A survey questionnaire was used to carry out field surveys from March 2001 to February 2002 at 27 fish landing sites around Trinidad. Results indicated that green multifilament net was generally used in artisanal drift gillnet operations that target carite, Scomberomorus brasiliensis , and kingfish, S. cavalla , on all coasts. Gillnet fishing was conducted year-round by 71% of the fishermen interviewed. Of the turtle species captured in this fishery, the leatherback turtle, Dermochelys coriacea , was reported as the most common and problematic. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Herpetology Brill
