“…In addition to C. acoupa being a highly appreciated species, mainly in the northern region of South America, due to the meat quality (Isaac et al 1998), it also presents other values with its by-product, for example the swimming bladder (popularly known as sticking) which has high economic value ranging from 7.50 to 8.40 USD/kg (Mourão et al 2009). This by-product is used for the glue, gelatin, and clarifiers' production in the wine industry and also as food in Asian countries (Cervigón 1993). Other works were also developed for the integrated used of C. acoupa, such as tanning the species skin that can be used to obtain leather, generating income and reducing environmental impacts (Eiras et al 2015).…”

The present study describes the fishery and biology of Acoupa Weakfish Cynoscion acoupa, an important fishery resource in South America. We found and analyzed 31 articles and 10 publications about the species. Cynoscion acoupa is an estuarine marine species, which has a feeding habit with preference for fish and crustaceans. Its spawning occurs during two periods of the year and the size at maturity of females is 40 to 50 cm, while males mature earlier, with 38–40 cm. Their growth is considered slow to moderate, with growth coefficient k ranging from 0.13 to 0.28, and the species can reach up to 15 years of age. C. acoupa is target of commercial and recreational fisheries in estuarine and marine coastal environments, mainly in the northern region of South America. The fisheries occur throughout the year, with different fishing gear, being more frequent with gillnets. In addition, fishing is more frequent on juveniles, which may compromise the stock. This species is categorized as of Least Concern by the International Union for Conservation of Nature, although it has a high degree of vulnerability to fishing, which, combined with overexploitation, shows that C. acoupa should be listed as under threat of extinction to some degree. The lack of studies on the species makes it difficult to establish management measures. Therefore, further studies should be prioritized, especially on reproductive biology, growth and fishing exploitation.

Carangid fishes are commercially important in fisheries and aquaculture. They are distributed worldwide in both tropical and subtropical marine ecosystems. Their role in food webs is often unclear since their diet cannot be easily identified by traditional gut content analysis. They are suspected to prey on pelagic and benthic species, with clupeiform fishes being important dietary items for some species, though it is unknown whether carangids share food resources or show trophic segregation. Here, we used metabarcoding to overcome traditional challenges of taxonomic approaches to analyze the diet of seven carangid species caught as bycatch in the Brazilian southwest Atlantic sardine fishery. Stomach contents were processed from the following species: Caranx crysos, Caranx latus, Chloroscombrus chrysurus, Hemicaranx amblyrhynchus, Oligoplites saliens, Selene setapinnis, and Trachinotus carolinus. Identified diets were dominated by teleost fishes. The C. latus diet was the most distinct among the seven species, preferentially consuming Engraulis anchoita, but H. amblyrhynchus, O. saliens, and S. setapinnis also showed a trend of predominantly consuming small pelagic fishes. Finally, we found evidence of inter‐predation in carangids, especially strong between S. setapinnis and C. crysos, suggesting that consumption of early life stages may result in indirect competition through reduced recruitment in these fishes. These findings provide unprecedented insights into the biodiversity in marine ecosystems, especially the poorly known diet of carangid fishes.
