“…Mugil hospes Jordan & Culver, 1895 was also recorded in the province but was later identified as M. brevirostris (Ribeiro, 1915) (Menezes et al., 2015). The presence of M. incilis Hancock, 1,830 in this region remains uncertain: a review of mullet species of South America indicated that this species does not reach the Tropical Southwestern Atlantic (Menezes et al., 2015), while some authors continue to record the species in the area (e.g., Barletta & Dantas, 2016; Freire & Araújo, 2016).…”

The biodiversity crisis has had particularly harsh impacts on marine environments. However, there is still considerable uncertainty about how many species have been seriously impacted and the effectiveness of protection measures (e.g., marine protected areas or MPAs) due to high levels of cryptic species in many taxa. Here, we employ an integrative taxonomy approach to mullet species in the genus Mugil. In addition to its high economic value, this genus is notable for having diversified ~29 million years ago without marked morphological and ecological divergence. We obtained 129 specimens of Mugil from the Coral Coast MPA, the largest of its kind in the Tropical Southwestern Atlantic marine province. Although morphometric and meristic traits revealed six taxonomically recognized species, only five mitochondrial lineages were observed. All individuals morphologically identified as M. incilis belonged to the mitochondrial lineage of Mugil curema, which is consistent with misidentification of morphologically similar species and an overestimation of species diversity. Remarkably, Mugil species in our sample that diverged up to ~23 million years ago are also the most morphologically similar (M. curema and M. rubrioculus), suggesting extreme morphological conservatism, possibly driven by similarities in habitat use and life-history traits. This study demonstrates the potential utility of integrative taxonomy (including DNA barcoding) for contributing to the conservation and sustainable use of natural resources.

“…According to Braga et al (2001) and Silva Jr. et al (2015), sciaenids suffer a strong impact of shrimp fisheries . Considering the total biomass landed in Sergipe in 1950-2010, the Sciaenidae family also composed most of the total catch of fishes, followed by Lujanidae, Ariidae, and Centropomidae (Freire & Araújo 2016). Sciaenidae was also the family mostly represented in the bycatch of shrimp fisheries in other regions in Brazil, namely: North (Maia et al 2016, Sedrez et al 2013, Northeast, particularly in Bahia and Sergipe (Alcântara & Siqueira 2018, Santos et al 2008, Southeast (Coelho et al 1986), and South (Branco & Verani 2006, Freitas et al 2011, Schwarz Jr et al 2006).…”

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.

“…Nomenclatural issues in catch statistics have been known for a long time (Freire and Pauly, 2005), but this has to be continuously monitored to allow for checking possible changes in the abundance of different shrimp species. The reconstruction process for catches off Sergipe performed by Freire and Araújo (2016), e.g., erroneously considered 'camarão-branco' (name used for the largest shrimps landed) as P. schmitti, as this was the only information available at that time. Nevertheless, these largest shrimps are mainly represented by P. subtilis in Sergipe.…”
