“…No study was found addressing the size of specimens landed as 'miunça' and 'pescadinha' in coastal waters of Sergipe in general. Nevertheless, one study, dealing only with P. brasiliensis originating from 'miunça' and 'pescadinha', found out that despite the small size of the specimens of this species, they were almost entirely above the maturity size in 'miunça' and entirely in 'pescadinha' (Freire et al 2020b). In our study, some of the species had specimens below the estimated maturity size, such as P. virginicus, L. breviceps, and others not, as P. brasiliensis and S. brasiliensis.…”

The present study aimed at identifying fish species from the bycatch constituting the categories 'miunça' and 'pescadinha' landed by the shrimp fleet in the state of Sergipe, comparing with information from statistical bulletins, and assessing the occurrence of seasonal changes in this species composition. Samples were obtained each month directly from the shrimp boats fishing along the coast of Sergipe, when their catch was landed between August 2018 and July 2019. All fishes were identified, measured (total length; cm), and weighed (total weight; g). A total of 60 kg of fishes was analyzed, encompassing 1412 individuals of 35 species, belonging to 16 families. Sciaenidae, Polynemidae, and Haemulidae were the most representative families. The most abundant species in 'miunça' were Polydactylus virginicus, Larimus breviceps, Paralonchurus brasiliensis, and Stellifer brasiliensis. In 'pescadinha', the species with the highest number were P. virginicus, L. breviceps, and Conodon nobilis. About 70% of all species were observed in both categories, with individuals from 'pescadinha' being larger than 'miunça', but the magnitude of this difference changed in different months. Only eight species analyzed here were individually reported in bulletins of fishery statistics for Sergipe, representing 56.7% of the total sampled biomass, and other 15 were reported in groups including two or more species.

Population structure of <i>Paralonchurus brasiliensis</i> (Steindachner, 1875) (Perciformes: Sciaenidae) in the coast of Sergipe, northeastern Brazil

Abstract: Paralonchurus brasiliensis is one of the most common fish species found in the bycatch of shrimp trawling in Sergipe. We analyzed its population structure through four sampling programs, two using hired shrimp
