During a trawl survey in northwestern Trinidad, 99 species of fish from 50 families were recorded. Most of these occur from the Gulf of Mexico to Brazil, although a few are found within a wider geographical range, from Nova Scotia to Argentina. A range extension was found for the engraulid Anchoviella lepidentostole. The dominant family was Sciaenidae, followed by Carangidae, Clupeidae, and Haemulidae. The most abundant species was Cynoscion jamaicensis which constituted 29 per cent of the total catch in numbers, followed by Ctenosciaena gracilicirrhus (14%), and Chirocentrodon bleekerianus (11%). All other species comprised less than 5 per cent of total catch. Most species were more abundant in the dry season, except C. bleekerianus which was caught only during the wet season. Spawning was year-round but peaked during the dry season for C. jamaicensis, Micropogonias furnieri, Umbrina coroides, Haemulon parrai, H. steindachneri, and Lutjanus synagris, and in the wet season for L. vivanus.
