“…However, Ghodratizadeh et al (2011) observed an increase in the Ht, RBC and Hb in Cyprinus carpio, which could have been a result of the hemopoietic stimulation due to probiotic feed. The values of the MCHC in the present paper are similar to those reported for the same species by Affonso et al (2007) and Tavares -Dias et al (2008).…”

“…The values for monocytes found in all treatment groups are in agreement with those of Tavares- Dias et al (2008). Variation in blood parameters occur not only between different species, but also between individuals of the same species that inhabit different ecological niches and have therefore undergone physiological adaptations (Campbell and Murru, 1990).…”

“…In the present study an increase in the neutrophil count was observed between treated fish (both sexes) and timezero group fish. In a previous study, Tavares -Dias et al (2008) observed lower total leukocyte counts, resulting in a low neutrophil count in the same species. Basophils were found only in the fish fed with probiotic.…”

Summary The aim of the present study was to evaluate the influence of probiotics prepared from Bacillus subtilis (strain C‐3102‐Calsporin®; Calpis, Tokyo, Japan) as a dietary supplement on several reproductive aspects of female ‘matrinxã’(Brycon amazonicus), including hematological parameters, immunological characteristics and total lipid concentrations in muscle and liver tissue. The broodstock were kept in two ponds of 600 m2, at a density of 50 fish per pond, from March to November 2008. The fish were divided into two treatment groups: untreated control fish (T1), and fish fed with 10 g of probiotics per kg of ration (T2). Fish were fed a diet containing 32% crude protein (CP), 7% crude fat (CF), and 6.5% ether extract (EE) twice daily at a rate of 1% of the total biomass per day during the coldest months (May through August) and 3% during the warm season (March, April and September through November). During the reproductive period, 20 individuals from each treatment group were selected for the experiments; two doses of crude carp pituitary extract were given to females in 10‐h intervals, and one dose was given to the males at the same time the females were given the second dose. A total of 20 fish were used for the hematological analyses. After anesthetization, blood samples were withdrawn by caudal puncture to determine the total number of cells, differential and total leukocyte counts, thrombocyte count, hematocrit, hemoglobin rate and plasma cortisol and glucose levels. The hematimetric index mean corpuscular volume (VCM) and mean corpuscular hemoglobin concentration (MHCM) were calculated. Ten other ‘matrinxãs’ from the same groups were used to assess macrophage phagocytic activity and lipid levels. The results showed that females fed a probiotics‐supplemented diet exhibited an increase in numbers of oocytes and, consequently, had higher rates of fertilization and hatching of larvae. Probiotic‐treated fish also exhibited a significant increase in the phagocytic activity of macrophages, indicating an improvement in the immune system of breeders. Hematologic parameters were different in comparison to the time‐zero group, and plasma cortisol and glucose levels were higher in the females. The total lipids levels in muscle and liver tissue were lower in B. amazonicus that received feed supplemented with probiotics.

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.
