... Still, the species A. longinaris, X. dincao, and X. kroyeri presented the highest suitability values closest to the coast. Some penaeid shrimps do not depend on estuaries to complete their life cycles, such as X. kroyeri, and are most abundant at shallower depths (< 30 m) (Holthuis, 1980;D'Incao et al., 2002;Costa et al., 2003;Andriguetto-Filho et al., 2016). However, for P. serrata, sites with the highest environmental suitability were observed near the river mouth and in regions further away from the coastline, since this species commonly inhabits great depths (from 200 to 1000 m) in temperate zones (D'Incao, 1995). ...

... In Brazil, fisheries involve juveniles in estuaries and coastal lagoons (artisanal fishing), and adult stocks in the ocean (industrial fishing) (Dias Neto, 2015). Industrial fishing started in the 1940 s with an increase in production from 1965 to 1972 (Valentini et al., 1991). However, due to the absence of assessment and management of shrimp stocks and fishing effort, there was a decline in catches before stabilization beginning in the mid-1990 s, when stocks decreased consistently (Valentini et al., 1991;Dias Neto, 2011). ...

... A espécie X. kroyeri não apresenta estratificação populacional, sendo comum a ocorrência de juvenis e adultos na mesma área (Branco, 2005). Pelas características do ciclo de vida das espécies e da pesca de Sergipe indicam que os indivíduos jovens e adultos de X. kroyeri são alvo das capturas e somente parte da população de Litopenaeus schmitti e o Penaeus subtilis são capturas, especialmente quando se encontram no processo de migração dos estuários para o mar (Valentini et al., 1991;Braga, 2000;Branco, 2005;Heckler et al., 2013). Estudo recente indicou que a área de proteção de duas milhas náuticas da costa, embora visando a proteção das tartarugas marinhas, desempenha um papel importante na proteção das espécies de camarão X. kroyeri e L. schmitti, apoiando a gestão e conservação dessas ações naturais. ...

... Therefore, what can we do? The zoning of fishing by fleet, further rules for trawling, further inspection, reduction of target stocks and bycatch species threatened with extinction or not, banning of trawling, and creation of marine protected areas are measures that scholars have claimed over the years (Haimovici and Mendonca, 1996;Perez et al., 2001;Haimovici et al., 2006;Hilborn et al., 2006;Lessa and Vooren, 2007;Rosso, 2015;Ricardo-Pezzuto and Mastella-Benincà, 2017;Dias et al., 2020). However, governments have done little. ...
