The hematological parameters of the two-year-old carp (Cyprinus carpio) under combined stressed were studied. quantitative and qualitative deviations in blood composition found experimental group against control group. Neutrophilia, monocytosis lymphocytopenia identified as well an increased number young forms erythrocytes background stress factors.

Presently, aquatic pollution by ammonium compounds, due to their large scale production and the indiscriminate usage for the agriculture and aquaculture farms, has earned an important place among the environmental pollutants. Industrial effluents, bio degradation of waste products and food remains also contribute for the formation of considerable quantity of ammonia in the environment. Ammonia ...

determination of metal levels in muscle, liver and gill of common carp ( cyprinus carpio ) species caught from shirinsu wetland was done using icp-oes. the mean level of cu, pb and zn in muscle, liver and gill of fish were 0.01±0.002, 0.015±0.003, 0.007±0.001; 0.13±0.005, 0.006±0.001, 0.62±0.11 and 0.26±0.008, 0.009±0.002, 0.53±0.10 μg g −1 , respectively. metal levels in muscle were generally ...

in the present investigation a total of six parasite species, some eye-specific and others non-organ specific parasites were found in the eyes of 48 examined fish species, collected from fresh and brackish waters of iran during 2004-2006. ichthyophthirius multifiliis  was isolated from the external surface of the eyes of oncorhynchus mykiss, gyrodactylus stankovici from cyprinus carpio and lern...

A species not identifiable with any of the about 23 Myxobolus species recorded from the common carp so far, was detected in the gills of one- and two-summer-old specimens of the common carp ((Cyprinus carpio L.) cultured in pond farms in Hungary. The strictly tissue-specific plasmodia of the parasite were located, surrounded by hyaline cartilage cells, in the chondrous substance of the terminal...

In carp exposed to pH 5.2 in fresh water, the Ca2+ influx from the water is reduced by 31% when compared to fish in water of neutral pH. At pH 5.2, the Ca2+ influx but not Na+ uptake is decreased by aluminum (Al). Al reduces Ca2+ influx dose-dependently: a maximum 55% reduction was observed after 1-2 h exposure to 200 micrograms.1(-1) (7.4 microM) Al. Branchial Ca2+ efflux is less sensitive to ...

Any alteration in fish physiology indicates the deterioration of water quality parameters, since fish are one of the biological indicators of water quality. The recent development of biomarkers based on the study of the response of organisms to toxic chemicals has provided essential tools for the implementation of environment contamination monitoring programmes (Korami et al., 2000). Toxicants ...
