TLDR
TLC depicted significant increase in all fishes following exposure to Manganese, and DLC was observed to register an increase in number of lymphocytes, monocytes and eosinophils but a decrease in neutrophils, basophils and thrombocyte population.Abstract:
In the present study, an attempt has been made to study the effect of heavy metal Manganese (MnSO4) on the haematological parameters of fish Garra gotyla gotyla for 9 weeks experimental duration. 96 hours LC50 value of Manganese for G. gotyla gotyla was found to be 3.2 mg/l and three concentrations viz. 20%, 40% and 60% of LC50 were employed during experimental period. The parameters evaluated include total erythrocyte count (TEC), haemoglobin (Hb), haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), total leucocyte count (TLC) and differential leucocyte count (DLC). Compared to control groups, TEC, Hb and Hct were found to exhibit significant decline whereas MCV and MCH exhibited overall increase in all concentration groups while MCHC contrarily exhibited fluctuating pattern. TLC depicted significant increase in all fishes following exposure to Manganese. DLC was observed to register an increase in number of lymphocytes, monocytes and eosinophils but a decrease in neutrophils, basophils and thrombocyte population.read more

Antioxidant defense system, immune response and erythron profile modulation in gold fish, Carassius auratus, after acute manganese treatment
TL;DR: The data shown that manganese could trigger antioxidant response, modulate immune response and induce erythron profile modification leading to eryptosis, compromising the blood oxygen carrying capacity, and overall health status in fish.

Multidisciplinary haematology as prognostic device in environmental and xenobiotic stress-induced response in fish
TL;DR: This review shows how some environmental and xenobiotic factors are capable to modulating the haematic cells and points out the importance of the use of mitochondrial activities as part of haematological evaluations associated to environment or aquaculture stress.

TL;DR: High trace metal concentrations in estuarine sediments and trace metal bioaccumulation in fish was correlated with the biosynthesis of metallothionein and reduced glutathione in both, liver and muscle, tissues, suggesting active physiological responses to contamination sources.

TL;DR: Results suggest that 2.0 mgl(-1) is proposed as a biologically safe concentration which can be used for establishing tentative water quality criteria concerning of same size common carp and serum biochemical parameters as well as erythrocyte morphological changes are promising clinical diagnostic tools for assessing the effects of gallium compounds on common carp.

The effects of copper on blood and biochemical parameters of rainbow trout (Oncorhynchus mykiss).
TL;DR: The return of elevated hematological and biochemical parameters to control levels after 3 days and the stabilization of hepatic metallothionein mRNA expression and copper concentration over a similar time period suggested acclimation to dissolved copper at 26.9 μg/L.
