Fishes are very sensitive to a wide variety of toxicants in water, various species of fish show uptake and accumulation of many contaminants or toxicants such as pesticides. The fresh water fish, Cyprinus carpio was exposed to methoxychlor and the median lethal concentration was found to be 0.42 ppm. After sublethalexposure tissues such as gill, liver, kidney, muscle and brain were sacrificed and analysed for protein content.

Abstract Objective Fish and crustacean are important sources of animal proteins and other essential nutrients required in the human diet. They are widely accepted for their high palatability, high protein content and tender flesh. In this study, proximate analyses were done for flesh of brackish water shrimp species Penaeus monodon and fresh water fish species Oreochromis niloticus .Results Percentage of protein content was high values in Penaeus monodon (9.31±0.63) compared to Oreochromis niloticus (7.85±0.79). The highest lipid content was present in Penaeus monodon (0.23±0.22%) while the lowest value was shown by Oreochromis niloticus (0.07±0.16%). Comperativily, the percentage of total carbohydrate content is the highest in Brackish water shrimp than fresh water fish Nile tilapia. The study revealed high protein content and a high fat content in the meat of Penaeus monodon . Information on the nutrient composition of Penaeus monodon is needed to encourage the processing, utilization and marketing of this commonest species of Sri Lanka. It can then be inferred that the shrimps ( Penaeus monodon ) could be employed as a supplement of protein and minerals, so as to balance human nutrition. Hence the consumption of shrimps ( Penaeus monodon ) would help as a good source of nutrients.

The fresh water fish Puntius ticto were exposed to lethal concentration of water soluble fraction (WSF) of petrol (5%-PF1, 10%-PF2, 15%-PF3, 20%-PF4 and 25%-PF5) for 96 hours. The exposure of WSF produced some conspicuous histopathological changes in liver. The swelling of hepatocytes, degeneration, necrosis, hemolysis, dilation, congestion and fibrosis in blood sinusoids were the prominent changes observed. The histological analysis showed increasing damages dose-dependents and time-dependents.
