Resumo: | The aim of this study was to evaluate the chronic salinity tolerance of Carassius auratus and the effects on blood parameters, gill morphology, and survival. In the first test, nine different concentrations (0.0, 0.5, 1.0, 2.5, 5.0, 10, 15, 20, and 25 g L-1) of NaCl were used with nine repetitions for 96 h. The survival of fish subjected to 15 g L-1 NaCl was 4 h, and 5 min at a concentration of 25 g L-1. The mortality of fish with 15 g L-1 NaCl was 100%. Morphological analyses of the gills showed hyperplasia of the coated cells in the interlamellar space and hypersecretion of mucus in fish exposed to 10 g L-1 of NaCl. At concentrations of 20 and 25 g L-1, necrosis of the support collagen caused the cells to detach from the lamellar structure mucosa. In the chronic test, two concentrations were used, with four replications containing nine fish in each aquarium for a period of 21 days. Blood samples and gills from the fish were collected, and it was observed that the fish showed a decrease in the concentration of bicarbonate (NaHCO3) in the blood, indicating hypernatremia. Acute exposure of C. auratus to sodium chloride (NaCl) should be at a maximum of 10 g L-1 of NaCl, after which level there would be a loss in animal performance and/or mortality. Chronic exposure to 5 g L-1 of NaCl promotes acidemia, ionic imbalance, and pathological changes in the gills; therefore, it is not recommended. |

No primeiro teste, foram utilizadas nove concentrações de NaCl (0.0, 0.5, 1.0, 2.5, 5.0, 10, 15, 20, e 25 g L-1) e nove repetições por 96 h. A sobrevivência dos peixes submetidos a até 15 g L-1 de NaCl foi de 04h00, sendo 00h05 na concentração de 25 g L-1 de NaCl. A mortalidade dos peixes com 15 g foi de 100%. As análises morfológicas das brânquias mostraram hiperplasia das células revestidas no espaço interlamelar e hipersecreção de muco em peixes expostos a uma concentração de 10 g L-1 de NaCl. Nas concentrações de 20 e 25 g L-1, observou-se que a colágeno de suporte perdeu a estrutura das células da mucosa, alterando as lamelas secundárias. Em um segundo experimento, um delineamento inteiramente casualizado foi utilizado com dois tratamentos (0 e 5 g L-1 de NaCl) e quatro repetições com nove peixes por 30 L em 21 dias. Amostras de sangue e brânquias dos peixes foram coletadas e observou-se que os peixes apresentaram diminuição nas concentrações de bicarbonato (NaHCO3) no sangue, indicando hipernatremia. Conclui-se que a exposição aguda de C. auratus ao cloreto de sódio (NaCl) deve ser de no máximo 10 g L-1, levando à perda de desempenho e/ou mortalidade dos animais. A exposição crônica a 5 g L-1 de NaCl promove acidemia, desequilíbrio iônico e alterações patológicas nas brânquias, por isso não é recomendado.UEL2021-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Históricaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4194910.5433/1679-0359.2021v42n5p2993Semina: Ciências Agrárias; Vol. 42 No. 5 (2021); 2993-3006Semina: Ciências Agrárias; v. 42 n. 5 (2021); 2993-30061679-03591676-546Xreponame:Semina.
