  abstract = {{W}e used complementary stable isotope ({SIA}) and stomach content ({SCA}) analyses to investigate feeding relationships among species of the nektobenthic communities and the potential ecological effects of the bottom trawling of a coastal ecosystem in northeastern {B}razil. {C}arbon (delta {C}-13) and nitrogen (delta {N}-15) compositions were determined for five basal sources and 28 consumers, from zooplankton to shrimp and fish species. {F}ishes and basal sources showed a broad range of delta {N}-15 (fishes: 6.49-14.94 parts per thousand; sources: 2.58-6.79 parts per thousand) and delta {C}-13 values (fishes: -23.86 to -13.71 parts per thousand; sources: -24.32 to -13.53 parts per thousand), while shrimps and crabs exhibited similar nitrogen and carbon ratios. {S}ix trophic consumer groups were determined among zooplankton, crustaceans and fishes by {SIA}, with trophic pathways associated mostly with benthic sources. {SCA} results indicated a preference for benthic invertebrates, mainly worms, crabs and shrimps, as prey for the fish fauna, highlighting their importance in the food web. {I}n overall, differences between {SCA} and the {SIA} approaches were observed, except for groups composed mainly for shrimps and some species of high delta {N}-15 values, mostly piscivorous and zoobenthivores. {G}iven the absence of regulation for bottom trawling activities in the area, the cumulative effects of trawling on population parameters, species composition, potentially decreasing the abundance of benthic preys (e.g., shrimps, worms and crabs) may lead to changes in the trophic structure potentially affect the food web and the sustainability of the fishery.},
