“…Eosinophils, monocytes and basophils were not seenin fish, thus indicate decreased concentrationof these cells in fish. Romao et al (2006) also confirmed theabsence of eosinophils, basophils and granulocytes in Hoplias malabaricus captured from the wild. According to Ranzani-Paiva (1995), preservation of basophils are not easy, hence could be the reason for its scarcity in fish.…”

Effects of sub-acute exposure of pesticide aronil (propanil) on haematology and serum biochemistry of Oreochromis niloticus juvenile was investigated in the present study. Sub-acute doses (0.21 mg/l, 0.43 mg/l and 0.83 mg/l) were derived from 1/20, 1/10 and 1/5 of the 96h LC 50 (4.17 mg/l) of aronil, in which fish specimens were exposed for eight weeks. Control group was exposed to dechlorinated tap water. Haematology and serum biochemistry of fish were examined at week 2, 6 and 8 of aronil exposure. Significant and dose dependent decreases in red blood cell, haemoglobin and haematocrit were observed in aronil exposed fish compared to the control. White blood cell, mean cell haemoglobin and mean cell haemoglobin concentration of the control were significantly lower compared to the exposed fish groups. Neutrophil and lymphocyte percentages were elevated significantly in 0.83 mg/l exposed fish when compared to other exposed fish and the control at the eight week. Basophils, eosinophils and monocytes were not observed in aronil exposed fish. Significant and dose dependent increases in glucose, protein, aspartate aminotransferase, alanine aminotransferase and triglyceride were observed in aronil treated fish with reference to the control while insignificant changes in cholesterol level was observed in the exposed fish compared to the control. Aronil pesticide induced stress and had toxic effect on O. niloticus. Use of pesticide aronil should be regulated especially in farm lands along the coast and riversides to avoid the influx of pesticides into the aquatic ecosystems.

“…chemical pollutants found in the lake water that could be responsible for the increase in the number of leukocytes. These results are comparable with those obtained by Romã o et al (2006) and Ates et al (2007), which demonstrated that blood parameters can be used as indicators of aquatic environmental parameters. After a biochemical and blood survey of fish exposed to pollutants, these authors found variations including the increase in the number of total leukocytes in individuals exposed to polluted environments such as urban lakes.…”

In this study, we investigated the effects of contaminated water on the blood parameters of the fish Prochilodus lineatus exposed during 7 and 20 days. Blood was collected with heparinized syringes, and blood smears were prepared and stained with Leishman stain. Slides were examined and photographed using a Leica light microscope. Total white blood cell counts and differential counts of thrombocytes and leukocytes were obtained for statistical analysis. The group exposed to water samples from Lago Azul exhibited an increase in the number of leukocytes and in the total number of white blood cells, suggesting that the chemical contaminants in this environment were acting similarly to antigens in this fish species, causing the proliferation of defense cells. In the group exposed to detergent during 20 days, the number of thrombocytes decreased. These results suggest that the variations in the number of leukocytes were indicators of environmental pollution and that biodegradable detergents may, after a certain time of exposure, affect vital functions in fish, such as coagulation and prevention of infections, which directly involves thrombocytes.

“…O número de eritrócitos e hematócrito do acará disco diferem da média para os demais peixes (TA-BELA 3), apresentando menores valores, talvez por seu comportamento lêntico (TAVARES-DIAS;MORAIS, 2004), o que poderia indicar uma menor eficiência no transporte de oxigênio, porém ressalta-se a maior concentração de hemoglobina corpuscular (CHCM), indicando que apesar de possuir menor número de eritrócitos entre as espécies consultadas na literatura há uma maior concentração de hemoglobina nesse eritrócito, demonstrando uma compensação no transporte de oxigênio (HRUBEC et al, 2000;ROMÃO et al, 2006;ADHAMI et al, 2017).…”

The species Symphysodon aequifasciatus is an ornamental fish of great economic importance in national and international trade, however, physiological and sanitary aspects on captivity conditions is unknown. Thus, the aim of present study was to determine the basal hematological profile of discus fish maintained on captivity conditions. For this, 14 wild adult animals were acclimated to laboratory with similar conditions to their natural habitat. The fish blood was collected by puncture of the caudal vein for erythrogram, thrombocyte and leukogram analyses. There were higher frequency
