Recent statements from the Brazilian federal government indicate that impacting economic activities, particularly commercial shrimp farming, are being encouraged in mangrove areas in the near future. Alterations of the National Action Plan and legal instruments that partially protected mangrove ecosystems have created an even weaker legal framework than previously existed. Such changes are leading Brazil far from the global call to conserve mangroves and from the Aichi targets and United Nations Sustainable Development Goals. Unfortunately, the loss of mangrove ecosystems and their ecosystem services will negatively impact living standards for Brazilians in coastal areas.

A pesca do camarão-sete-barbas, é eficaz na obtenção da espécie-alvo, mas pouco seletiva por capturar elevada quantidade de fauna acompanhante. Diante disso, o presente estudo buscou caracterizar as capturas camaroeiras no litoral catarinense, como também evidenciar padrões ambientais e a composição da carcinofauna registrada. Campanhas mensais (140) ocorreram em três pontos de estudo, totalizando 420 arrastos, os quais foram agrupados por estação do ano. A Análise Discriminante demonstrou oscilação na salinidade e temperatura entre as estações. A carcinofauna foi composta por espécies com abundí­¢ncias e frequências distintas, sendo que aparentemente as variações das condições ambientais estiveram associadas í­Â formação de comunidades sazonais na área, conforme os resultados obtidos pela análise ANOSIM (R = 0,247; p = 0,001). A Análise da Porcentagem compreensão sobre o funcionamento do ecossistema explorado de Similaridade evidenciou que as espécies que mais contribuí­­ram para as diferenças foram: X. kroyeri, A. longinaris, P. muelleri e C. ornatus. Tais variações resultaram em proporções de recursoalvo/carcinofauna diferentes (Qui-Quadrado: X2 = 31,01; GL = 6; p < 0,000001).

The differences between abundance and the relationship with aspects of population and reproductive Stellifer rastrifer, Stellifer stellifer and Stellifer brasiliensis were analysed. Data were collected monthly trawl directed for capture of seabob shrimp in Armação do Itapocoroy, an important fishing area on the southern Brazilian coast. The chi-square test showed that the population of S. rastrifer presented values of capture significantly higher than others in all evaluated periods. The frequency distribution of total length curves combined with records of the size at first maturity (L50) showed that S. rastrifer is a species with a majority of the adults effectively participating in the reproductive period. The frequency of occurrence of individuals in reproduction monthly examined together with changes in the gonadosomatic index (GSI) and the reproductive activity index indicated that spring was the main breeding season for the three species. However, it was observed that the reproductive period of S. rastrifer was more pronounced and more extensive than that of its congeners, apparently providing it with ecological advantages and enabling a more effective population balance given the pressure exerted by fishing in the study area.
