“…Additionally, changes in toxicity were not observed during or after the road construction for any evaluated point, because the average number of dead/still organisms was statistically similar. Similar results were found by Vaz et al (2010), who studied the toxicity of Babitonga Bay (Santa Catarina, Brazil), also with the A. salina bioindicator. The data showed that the vast majority of the evaluated points was not toxic to the micro shellfish.…”

With the goal of assessing possible impacts of fish farming in great-volume cage systems on the water quality of a reservoir, the authors provided abiotic data from 72 samples obtained before and after farming site implementation. The figure shows the principal components analysis results for seven limnological variables. The highest dissolved oxygen (OD) concentrations were observed before the fish farm became operational. During the post-production period, the highest phosphorous (PT) and ammonium (NH4) concentrations were observed as well as high conductivity and turbidity values. Authors concluded that fish farming in cage systems located in Solteira Island Reservoir, Brazil, caused significant temporal and sudden spatial changes in water physical and chemical variables.

Environmental contamination in estuaries has been assessed by studying selected fish species such as M. curema as biological indicators, with reports of gonadal malformation and intersexuality of natural origin or attributable to anthropogenic influence (García-Gasca et al, 2016).…”

This study describes the occurrence of reproductive changes in a mullet (Mugil curema) from the Babibtonga Bay, Santa Catarina. Gross and microscopic findings indicated changes in the reproductive system that were characterized by the presence of both male and female gonads, nearing sexual maturity, which was compatible with the diagnosis of intersex. It was not possible to identify predisposing factors that may have contributed to the development of this condition. However, as this species of fish may have their reproductive development affected by anthropogenic influence, it is important to permanently monitor this kind of environment. Considering the number of fish belonging to this species that was examined (n=433), the estimated prevalence for intersexuality was 0.23% (confidence interval: 0.00 to 0.68%, with confidence level of 95%). The findings in this study support the diagnosis of intersexuality in M. curema from the Babitonga Bay, which is the first documented case of this condition in this species on the coast of Santa Catarina, Brazil.

“…A alta carga de poluentes na água do estuário da Babitonga causa redução de fertilidade no misídeo Mysidopsis juniae , bem como elevadas taxas de mortalidade em Artemia salina (Vaz et al, 2010a). Ainda que esses estudos sejam preliminares e restritos, tanto em termos taxonômicos quanto temporais, eles fornecem uma indicação geral dos efeitos na biota local e sugerem um ecossistema degradado.…”

O zooplâncton é um importante elo nas teias tróficas aquáticas, além de representar uma parcela considerável da biodiversidade. No presente estudo, revisamos o conhecimento sobre a comunidade zooplanctônica no estuário da Babitonga e áreas costeiras adjacentes visando fornecer subsídios para elaboração de planos de conservação e manejo locais. O estudo do zooplâncton na região é recente, desde 2002, com maior esforço amostral no canal principal do estuário. Um total de 261 espécies foram registrados até o momento, sendo 159 invertebrados e 102 larvas de peixes, incluindo sete espécies exóticas. A região ainda carece de estudos, principalmente nas áreas mais internas do estuário, bem como para diversos grupos taxonômicos (e.g. moluscos, quetognatos, apendiculárias) e aspectos como interações tróficas e simbióticas, reprodução, produção secundária, dinâmica populacional, padrões de flutuação em curto e longo-prazo, e a influência de eventos climáticos e mudanças climáticas na composição, distribuição e abundância das espécies.
