dc.descriptionMacrobrachium amazonicum is a native freshwater shrimp from the northern region of Brazil, widely distributed throughout the Amazon basin, which supports an extensive regional fishery. Here, we assessed its dietary habits in the wild in a prime fishery area for this species in the lower Amazonas River (Pará state, Brazil) and evaluated the relative efficiency of three bait types (cooked rice, canned sardines, and babassu fruit meal) for both its quantitative and qualitative capture yield. Stomach contents were analyzed using occurrence frequency, the point method, and the food index. We identified four food categories: fine particulate organic matter (FPOM), coarse particulate organic matter (CPOM), particulate plant matter (PPM), and identified plant matter (INV) (leaves, root remains, and invertebrates). According to the frequency of occurrence and the point method, fine particulate organic matter (FPOM) was the most important food category (88%). In the bait attractiveness test, the average number of shrimps and total biomass captured varied significantly among treatments, with babassu flour being the most attractive. Our results indicate that M. amazonicum is omnivorous and an opportunistic generalist shrimp, and that among the three baits tested, babassu meal likely renders higher yields.
