As pescarias de arrasto motorizado direcionadas às capturas do camarão sete-barbas Xiphopenaeus kroyeri (Heller, 1862), também atuam sobre as populações de espécies de peixes da fauna acompanhante. A pesca de arrasto gera elevada biomassa de pequenas espécies, utilizada como uma valiosa fonte de alimento. As amostragens dos peixes da fauna acompanhante foram efetuadas mensalmente, entre janeiro de 2003 e dezembro de 2004, nos desembarques de barcos da frota artesanal caravelense. Foram amostrados 22.300 indivíduos, pertencentes a 31 famílias, correspondendo a 63 espécies, tendo oito dessas participado com 70,7% do total de indivíduos identificados; desse total de espécies, 18 espécies foram consideradas frequentes, 17 pouco frequentes, 11 com frequência regular, 12 sazonais e 5 ocasionais. O comprimento total variou entre 1,0cm e 53,0cm, com média geral de 12,3cm

Quali-quantitative appraisal of the fish by-catch in the fishery for seabob shrimp, Xiphopenaeus kroyeri (Heller, 1862) in the Caravelas county, Bahia state, Brazil The motorized trawl fishery meant for the capture of seabob shrimp, Xiphopenaeus kroyeri (Heller, 1862), has an additional impact on the populations of many by-catch fish which share the same living grounds. However, this activity has the advantage of functioning as a valuable source of food represented by the landed small sized fish species. The sampling for the fish by-catch was performed monthly from January, 2003 through December, 2004, during landings from the Caravelas small-scale fleet. Overall, 22,300 individuals belonging to 63 species, distributed over 31 families, were sampled. The majority of the by-catch was comprised by eight species, whose catch in numbers amounted to 70.7% of the total catch. According with its frequency of occurrence the 63 species caught as by-catch were categorized as occasional (21 species), seasonal (13 species) and regular (29 species). Total length for all by-catch species ranged from 1.0 cm to 53.0cm, with
