Immune Response In A Pollutent Stressed Fish
Dr. P. V. Kolkhede
Aquatic animals are constantly being exposed to an array of toxic substances which are leaching through industrial effluents and agriculture. To protect by these dreadful chemicals these animals are naturally endowed by an intrinsic self sustaining defense system. Fish are first group of organisms that possess an innate and adaptive immune system1.In fish immune system skin mucosa is very important part serving as an anatomical and physiological barrier against external hazards. Skin mucosa cells of fishes can be used to maintain stress in them .Stress hormones adrenocorticotrophins are produced by leucocytes to allow for bidirectional communication between neuroendocrine system and immune system2.Circulating leucocytes are the key cells of vertebrate innate immunity, namely eosinophils,macrophages, and neutrophils3. Hence the following study has been undertaken to evaluate stress in freshwater edible fish, Channa orientalis (Sch) exposed to cypermethrin on blood parameter leukocyte.
In the present investigation, Channa orientalis exposed to sub lethal concentration of cypermethrin showed marked behavioral changes, large secretion of mucous ,pale white in colour and became lethargic .A reduction in total leukocyte count within few hours but then steady increase in the count signify that secretion of mucus on body may be an adaptive response for protection against corrosive nature of pesticide to combat against toxicant stress4 which in turn reflects the gearing up of the defense mechanism against pollution stress.
Keywords- Leukocyte count, pollutant, lethality, mucous, stress
