AB The brown comber (Serranus hepatus) is a small benthopelagic species with no commercialvalue, primarily caught by bottom trawls as a by-catch. In this work, we studied the feeding habitsof this species. For this purpose, samples were obtained from the trawl fleet within the differenteditions of the ECOFISH project carried out between 2019 and 2022. A total of 1534 individuals wereanalyzed. In the diet analysis, various factors were considered, such as the season, the depth, andthe time of day of the capture, as well as the size range of the individuals caught. For the feedinganalysis, different indexes were calculated, such as the vacuity index (%Vi) and index of relativeimportance (%IRI). The size range of the specimens was between 3.2–16.3 cm, and the weight wasbetween 1.02–39.73 g. Of the stomach content analyzed, 49.7% of the stomachs were found to beempty. The resources with the greatest importance in the diet of the brown comber were from thecrustacean group, especially mysidaceans and decapods. There were differences in the diet accordingto season, depth, and size; however, there was no variation in diet by the time of day.
