A taxonomical and structural analysis of the fish community in the Gulf of Tribuga, northern Colombian Pacific, was done based on information from different artisanal fishing techniques (hand lines, long lines, gillnets, trawl nets, harpoons, throw nets) and visual identification by scuba diving. As many as 191 species were registered, belonging to 21 orders and 68 families. Hand lines (71 species) and long lines (41 species) were used systematically and consecutively throughout the sampling period. Therefore, the catch analysis was carried out using only the fish caught with these two techniques. The most abundant families were Carangidae (8.9%), Serranidae (6.3%), and Lutjanidae (4.2%). These families, along with Scombridae and Ophidiidae, contributed the most in number, biomass, commercial importance, and human consumption by the local communities. The top ten species captured during sampling were the skipjack tuna (Euthynnus lineatus), sierra mackerel (Scomberomorus sierra), Gulf Coney (Epinephelus acanthistius), Clark's brotula (Brotula clarkae), spotted rose snapper (Lutjanus guuatus), yellow snapper (Lutjanus argentiventris), almaco jack (Seriola rivoliana), Pacific crevalle jack (Caranx caninus), green jack (Caranx caballus), and purse-eyed scad (Selar crumenophthalmus). The mocosa ruff, Schedophilus haedrichi (Centrolophidae), is reported for first time in the northern Colombian Pacific. Keywords: composition, fish community, artisanal fishing gear, Schedophilus haedrichi, Gulf of Tribuga, eastern Tropical Pacific. Se realizo el analisis taxonomico y estructural de la comunidad ictica del golfo Tribuga zona norte del Pacifico colombiano, a partir de informacion recopilada mediante diferentes artes de pesca (volantin, espinel, trasmallo, barco arrastrero, arpon, atarraya) e identificacion visual con equipo de buceo autonomo. Se registraron 191 especies agrupadas en 21 ordenes y 68 familias. Los artes de pesca utilizados de manera sistematica y consecutiva durante el periodo de muestreo fueron la linea de mano y el espinel, capturando 71 y 47 especies respectivamente. Los analisis de las capturas se basaron solamente en los registros con estos dos artes de pesca. Se establecio que la familia Carangidae fue la mejor representada con el 8,9% del total de especies, seguida por Serranidae con 6,3% y Lutjanidae con el 4,2%. Estas familias junto con la Scombridae y Ophidiidae son las de mayor aporte numerico, biomasa, importancia comercial, y valor alimentario para las comunidades humanas asentadas en la zona de estudio. Las diez especies mas capturadas durante el muestreo fueron la patiseca (Euthynnus lineatus), sierra (Scomberomorus sierra), cherna (Epinephelus acanthistius), merluza (Brotula clarkae), pargo lunarejo (Lutjanus guttatus), pargo amarillo (Lutjanus argentiventris), bravo (Seriola rivoliana), jurel (Caranx caninus), burique (Caranx caballus), y ojote (Selar crumenophthalmus). Se reporta por primera vez para el Pacifico norte colombiano Schedophilus haedrichi (familia Centrolophidae). Palabras clave: composicion, comunidad icticas, artes de pesca artesanal, Schedophilus haedrichi, golfo de Tribuga, Pacifico oriental tropical.
