We investigated how the taxonomic and functional structures of the fish fauna in estuaries along the Brazilian semiarid coast (BSC) vary between estuarine zones and seasons. Standardized collection methods sampled fish in five estuaries of the BSC. Each species was categorized by trophic guild and estuarine use guild, and fish–estuary association score (FEAS). Non-metric multidimensional scaling (nMDS) analyzed species and trophic guild compositions according to zone and season. PERMANOVA tested differences among groups. Similarity percentage (SIMPER) analysis and the relative preference index (RPi) identified the species and trophic guilds that contributed most to group distinction (lower zone versus upper zone, and dry season versus rainy season). In total, 113 fish species were recorded. The most representative estuarine use guilds were marine migrants and estuarine. Among the nine trophic guilds, the most representative were detritivores, omnivores, opportunists, macrocarnivores, and zoobenthivores. Taxonomic (species composition) and functional (trophic guilds) approaches revealed both spatial and temporal differences. The functional approach using FEAS detected spatial variation of small magnitude and indicated temporal homogeneity. Thus, there is substantial taxonomic and functional heterogeneity considering approaches from species, estuarine use guilds, and trophic guilds.

From two field campaigns, carried out in 2020 and 2022, the following environments were studied: interdune lagoons, lagoons located in the deflation zone, streams that flow into the sea,and the Botija stream. The 80 samples revealed the existence of 14 species, distributed in ten families and eight orders. Currently, no species is at risk of extinction. Biodiversity was considered low, considering the absolute number of species and the values of the ecological diversity indexes (between 0.97 and 1.43) and species richness (between 0.45 and 1.52). Consequently, equitability was also low, with numerical participation concentrated in four species: Poecilia vivipara, Cichlasoma orientale, Astyanax bimaculatus,and Oreochromis niloticus. In addition to being dominant, the last species was classified as an invasive exotic, therefore, with a high potential for environmental impact. The species Steindachnerina brevipinnaand Crenicichlasp. are also not part of the native faunabut offerlower risk potential. It is believed that the difference in fish assemblages is related to the level of connectivity and environmental characteristics of the different aquifers.

There are many challenges in balancing the various conflicting interests in this environmental area. The State Environmental Superintendence of Ceará developsthe Beach Suitability Monitoring Program, with the main objective of monitoring the quality of beach waters for primary use; with a greater scope of monitoring points on the coast of Fortaleza. The objective of this study was to analyze the efficiency of monitoring the coast of Fortaleza, and used the Data Envelopment Analysis (DEA) technique as an instrument for analyzing relative efficiency. DEA uses decision-making units (DMU) to analyze their performance in using their inputs to produce outputs. Five different analysis scenarios were used, taking as DMUs the three years of management of the Bathing Suitability Program (2019 to 2021). The results showed that the lowest efficiency result in all scenarios was 82.30% (most efficiencies were 100%) and that therefore the monitoring of the bathing suitability of the Fortaleza coast can be considered efficient given the chosen sample, but there is room for improvements to be implemented.
