Environmental, nutritional, size and age conditions cause many direct and indirect changes in the blood and serum indices of fish in different species. The aim of this study was to determine and evaluate the changes in hematological indicators and some biochemical indicators of Cyprinus carpio blood serum in different weights. For this purpose, common carp farmed in the weight range of 500 to 2000 g were examined and analyzed in 5 weight groups of 500, 700, 1000, 1300 and 1600 g. The studied fish were bred and examined in a 2-hectare pool in one of the farms of Sari city under the same conditions. To perform blood tests, 5 fish were used in each weight group and blood sampling was performed by cutting the vein of the caudal stem vein. The results of the study of hematological indicators and some serum biochemical indicators showed that in different weights, significant changes in the amount of red blood cells, hemoglobin, hematocrit, mean red blood cell volume, mean hemoglobin concentration, mean red blood cell hemoglobin concentration, white blood cells, lymphocyte, monocyte, granulocytes, glucose, urea, triglycerides, cholesterol, phosphorus, calcium, sodium, potassium, albumin, and total protein were not observed (P> 0.05). The results of the present study showed that weight changes did not affect the hematological indicators and some biochemical indicators of common carp blood serum.

Abstract In this study, the effect of stocking density on some hematological (Red and white blood cells) and serum biochemical parameters (Glucose, triglycerides, cholesterol, total protein, inorganic phosphorus, calcium and magnesium, enzymes alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase and cortisol) of Carassius auratus was investigated. Fish with average weight 200±18 g were stocked randomly into 6 tank with triplicate in two treatments for a 30-day period and were submitted to different stocking densities: low density (T1, 10 kg/m3) and high density (T2, 45 kg/m3). At the end of the trial, Fish from each group were selected and their blood was collected and the following parameters were analyzed. Fish held at high density showed significant higher levels of cortisol, glucose and alkaline phosphatase (23±0.4 ng/dl, 52±3.2 mg/dl and 93.2±8.1U/L, respectively) compared with those held at low density (36±0.9 ng/dl, 83±5.2 mg/dl and 61.2±6.3U/L, respectively), while the levels of triglycerides significantly decreased with increasing density (PP

The present study was performed to investigate the effects of various levels of dietary lactobacillus acidophilus as feed supplement on the growth performance, survival rate, hematological parameters and intestinal microbiota of guppy (Poecilia reticulata). For this purpose one-thousand and eight hundred guppy larvae with 7 mg mean weight in a completely randomized design with 4 treatments and 3 replicates of L. acidophilus in the diet, including no bacteria (control), 1.5×107, 3×107, 6×107 CFU g-1(T2,T3,T4 respectively) were considered and fed for 16 weeks. The results showed that significant differences (P4 and control group. The highest amount of white blood cell count (9.70±0.1) was observed in 4 group and had significant different (P>0.05) with control (5.96±0.2). The highest amount of intestinal of Lactobacillus was observed in 4 group compared to other groups and control (PL. acidophilus (6×107 CFU g-1) have significant effect on growth and white blood cell count of guppy.

Abstract Evaluation of probiotic is not summarized on growth but included the other aspects, such as blood parameters. In this study, effects of two bifidobacter, Bifidobacterium animalis and Bifidobacterium lactis with three concentrations of 1× 109 (T1), 2× 109 (T2) and 3× 109 (T2) CFU/100g were studied on growth performance and hematological parameters of rainbow trout larvae with initial body weight of 0.538 ± 0.197 g. Thus 3 experimental treatments and a control, each with three replicates were prepared. Thirty rainbow trout larvae were stocked in each replicate. The larvae were fed 4 times a day according to 4-8% of body weight. After 8 weeks of feeding trail with supplemented diet with Bifidobacterium growth and hematological parameters were studied. The result of hemoglobin showed no significant difference between experimental treatments and the control (P>0.05). The use of Bifidobacter caused increase of red and white blood cells in T3 and T2 treatments (P0.05). The study of hematological parameters, final weight and specific growth rate in present study showed that the use of bifidobacter increased blood cell account and also the final weight growth in rainbow trout.

Abstract In respect to nano-technological studies and physiological and biochemical lesions of these materials on aquatic animals, in this study we examine the toxicity effects of nano-zinc oxide (ZnO NPs) on hematological indices of common carp (Cyprinus carpio). LC50 of nano zinc oxide was determined according to the mortality at 24, 48, 72 and 96 hours, respectively. During separate experiment based on the LC50 levels, hematological parameters were studied with induction of the sub-lethal concentrations of nano zinc oxide. In this study, lethal toxicity concentration of nano-ZnO (LC50) for common carp was 3.120 ± 0.23 ppm. when the fish were exposed to sub lethal concentrations (50% of LC50) for 7days, the results showed that the nano-particles causes various changes in the blood parameters of the fish that these changes was affected by the nano-particles in blood indices by reducing the level of red blood cells (RBC), Hemoglobin, Hematocrit and increase in white blood cells (WBC) (P0.05) in the exposed nano-ZnO. The results of this study showed that the sub-lethal toxicity of nano-particles could have a negative impact on hematological indices of Common carp, so we should prevent the entrance of such substances to the aquatic ecosystems.
