“…In Brazil, in recent decades there has been an increase in studies related to natural fish feeding, with a higher concentration for the species of major commercial interest, mainly of rivers and lakes in the North, South and Southeast regions of the country. Knowing the diet and food interaction of fish in natural or artificial environments with the environment provides important ecological information, such as the mechanisms that allow the coexistence and exploitation of resources by several species (Goulding 1980) to understand the behavior of these species in face of changes in environmental conditions and food availability (Silva et al 2008).…”

The knowledge of the fish trophic structure has been outstanding for providing relevant information on the functioning of the ecosystem in which they are inserted, mainly in dammed environments of semiarid regions that suffer constant changes in the level of water, resulting in alterations, especially in the feeding of the fish due to the variation of the food resources throughout the year, causing changes in the diet of the local ichthyofauna. Within this context, the objective was to describe the trophic categories of fish species in freshwater environments of the Rio Grande do Norte state. Seven trophic guilds were recorded: Detritivore/iliophagous, Insectivorous, Carcinophagous, Piscivorous, Herbivorous and Omnivorous. Through the results, it is observed that the fish species inserted in different environments of the state present the same food pattern, demonstrating flexibility on the diet, prevailing a generalist alimentary habit.

Objective. To assess the relationship between structure and diet of the fish community and the riparian vegetation cover (RVC), in two hydrological periods (HYPE) in streams of the La Vieja river basin. Materials and methods. Collections were done with electrofishing and rapiché in March and May 2010. Efficiency of sampling effort was assessed with the estimator Chao2. Structure was analyzed using the indices of richness, dominance, diversity and evenness which were compared with an ANOVA. Gastrointestinal contents were analysed with the indices of vacuity coefficient, frequency, volume and food importance. We examined the relationship among diet, HYPE and RVC using the multiple correlation coefficient (r), the coefficient of determination (r2) and a Canonical Correspondence Analysis (CCA). Results. According to the Chao2 estimator, in most streams the fish species richness values are representative. There were no significant differences (P>0.05) among the structural variables, the HYPE and the RVC. According to r and r2 the diet of most fish species did not vary as a function of RVC and HYPE; however, according to the CCA diet varies as a function of HYPE but not of RVC. Conclusions. The fish community structure did not show changes according to RVC and HYPE. Although most species showed no changes in their diet, the community did show changes in diet according to HYPE, due to a change in composition; however diet changes were not detected by RVC. Key words: coffee-growing region, diet, fish community, hydrological period, riparian vegetation cover, structure.
