چکیده
This study was carried out on fish channa punctatus to investigate the lethal concentration of cadmium nitrate at 24 hr. Experiment procedure repeated five times selected concentrations, noting number killed. The mean value taken. These values were taken determine LC50 for Toxicity heavy metals it may be depends upon dose and time exposure period.

Comparative study on the haematological effect of synthetic and plant origin pesticides on fish Channa punctatus
Application of synthetic pesticides is one of the methods used to increase agriculture production, animal husbandry and welfare of mankind. Due to their long-term persistence, slow degradability toxicity to other organisms and accumulation inside the fish body, synthetic pesticides adversely affect the environment. To solve this problem, studies have been carried out on the possibility of using...

Present study has been undertaken to assess the toxicity of cadmium in vitro for viability of hepatocytes, lactate dehydrogenase leakage, glutathione and lipid peroxidation in Channa punctatus (Bloch), a freshwater snake head fish. Three concentrations of cadmium as cadmium chloride (0.1μg/ml; 3.0μg/ml and 5.0μg/ml) besides one control has been selected. Observations reveal that except lowest c...
متن کاملEffect of Endosulphan and Dimethoate Pesticides on Haematological Parameters of Fresh Water Fish Channa punctatus
Fish hematology is one of the most recent branches of physiology to assess the status of general health. Blood is the transport medium, a defense system, and an acid/base buffer system. Circulating blood is the common denominator of health and illness and alteration in its chemical or cellular illness and composition can indicate hematological and nonhematological diseases. Erythrocytes occupy ...
