“…The specimens were collected with the assistance of local shers, who captured the animals in sh weirs of varying sizes (young and adults, considering the tamanho de primeira maturação sexual estimado por Lima et al, 2019), which contributed to the minimization of any selective effects in terms of specimen size, with stress being reduced using the approach of Ishikawa et al (2010). The sh were placed immediately in a bucket containing water and 2% benzocaine (190mg/L) for approximately 3 minutes prior to biometry and the collection of blood samples.…”

Genotoxicity studies in coastal ecosystems have been a priority in Environmental Risk Assessment (ERA). This research aimed to study the genotoxicity by the micronucleus test and comet assay in two Brazilian Amazon estuaries (anthropized and control) using Plagioscion squamosissimus as a bioindicator. Blood samples were collected from 54 specimens. No significant genotoxic effects were detected in the cells analyzed, although the highest occurrence was observed in anthropized site. The percentage of genomic damage differed between the sites studied, being always higher in anthropizes site as well. Of the nucleoids analyzed in this site, on average 28±14.42% of the cells were classified in the highest damage class (4). The fish analyzed in the present study are direct influence of xenobiont agents capable of producing damage to the genetic material of aquatic organisms in both sites and, consequently, may bring consequences still little reported in studies of morphophysiological alterations in humans.
