O peixe-zebra (Danio rerio) como modelo emergente na ecotoxicologia

Abstract: A libertação de poluentes tradicionais e emergentes nos ecossistemas aquáticos tem levado à contaminação da água e sedimentos, o que pode afetar a saúde dos animais selvagens, das suas populações e contaminar as cadeias alimentares com consequências na ecologia, mas também na saúde pública. Estes diversos compostos tóxicos (incluindo os lipossolúveis e persistentes) podem chegar aos ecossistemas através de diferentes vias e os seus efeitos da exposição aguda e/ou crónica nos organismos não-alvo ainda não são b… Show more

“…In the case of Danio rerio, also known as zebrafish, knowledge of the morphological, physiological, biochemical, and genetic parameters in all its stages of development, as well as in both sexes, makes this fish an ideal model system to be used in toxicology research to identify the adverse effects of xenobiotics (CANEDO and ROCHA, 2021). In addition, zebrafish are small (about 4-5 cm), have rapid development, high fecundity, high adaptability to the laboratory environment, and easy maintenance (RIBEIRO et al, 2022). Rapid development is an excellent feature in genotoxicity studies, as it allows monitoring of all toxic effects in a short period and even transgenerational implications (DAI et al, 2014).…”

“…However, zebrafish have no genetically discernible sex and only exhibit sexual dimorphism three weeks after fertilization. Despite the limitations, interest in this species has grown immensely in recent decades, which is easily verified by the number of published scientific articles, and the species is currently a reference in toxicology (RIBEIRO et al, 2022).…”

“…Early life impacts, especially during embryonic development, can shape the future performance of organisms at the molecular and population levels. Early exposure to contaminants may have extensive consequences, impacting the overall health, molecular processes, and population dynamics of fish species beyond immediate effects [ 16 ].…”

“…Fish serve as suitable organisms for research because they play vital roles in the aquatic food chain and are efficacious bioindicators. Their heightened sensitivity to aquatic pollutants further underscores their importance in ecotoxicological studies [ 16 ]. Zebrafish ( Danio rerio ), freshwater teleost cyprinid fish, have emerged as a pivotal predictive and high-throughput model in toxicological research [ 17 ].…”
