Toxic effects of carbamate pesticide cartriz on the haematological characters in a facultative air breathing fish, Channa punctatus has been investigated in the present study. The intoxication of pesticide exhibited a significant decrease in RBC count, Haemoglobin concentration, packed cell volume (PCV) and oxygen carrying capacity of blood, whereas a progressive rise in total leucocyte count (TLC) and clotting time was observed in varying period of intoxication, revealing toxic nature of the agro chemical.

Indiscriminate use of pesticides including cartriz for getting better result in agriculture, has ultimately affected the aquatic biota in general and fishes in particular. The present investigation is aimed to study the adverse effects in the histological make up and gonado somatic index(GSI) of a fresh water fish, Channa punctatus (Bloch) exposed to sublethal concentration of carbamate pesticide, cartriz for different ovarian cycle. The pesticide produced deleterious changes in the ovarian structure and also caused significant changes in GSI, revealing its toxic nature. Parallelly a central set of experiment was kept for observation without any pesticide. Hence it is suggested to use cartriz within prescribed level, to save the environment

Activity of a few biomarkers have been investigated on fresh water fish, Channa punctatus exposed to three sub – lethal concentrations of dimethoate(1/5, 1/10 and 1/15 of 96hrs LC50 values). The alteration in protein contents of liver, gill and muscle were investigated. The protein levels were found to be depleted in all the tissues after exposure to dimethoate over the control.All the organs showed the significant difference between control and exposed groups in all the estimated parameters on long exposure. The present study considers biochemical parameters as important biomarkers in determining the level of toxicity caused by the pesticide Dimethoate. Therefore the detailed results and observations are summarized in the present investigations.

The present investigation deals with the prevalence of three cestode parasites viz. Lytocestus sp., Proteocephalus sp. and Gangesia sp. collected from the intestine of a freshwater fish Channa punctatus in different blocks of Meerut region (U.P.) India during June, 2014 to May, 2015. A total of 125 parasites were collected throughout theyear. The high incidence of infection of all these species Lytocestus sp., Proteocephalus sp., Gangesia sp. was recorded in summer season (70.83%, 77.27% abd 72 % respectively) followed by winter season (63.63%, 57.89% abd 52.38% respectively) whereas infection was low in monsoon season (36.84%, 27.78% abd 23.52% respectively). The present study clearly indicates that the intensity of infection throughout the year was found highest in summer season followed by winter and lowest in monsoon. Findings show that beginning of the breeding period, feeding habitat, presence of intermediate host and environmental factors are influencing the seasonality of cestode parasitic infection.
