qualitative and quantitative analyses of phyto- and zooplankton, and growth performance of cyprinus carpio linnaeus were done in earthen vats receiving compost, diammonium phosphate and vermicompost as direct application fertilizer were conducted. significant differences were observed in the diversity and abundance of plankton in response to fertilization. the highest production of fish was obt...

The aim of the study was to investigate effects of the triazine's herbicide terbuthylazine-2-hydroxy on early life stage of common carp (Cyprinus carpio L.) through antioxidant indices, mortality, growth, development, and histopathology. Based on accumulated mortality in the experimental groups, lethal concentrations of terbuthylazine-2-hydroxy were estimated at 35-day LC50 = 10.9 mg/L terbuthy...

common carp, cyprinus carpio (l.) were blood-sampled after 0, 2, 6, 12, 24, 48 and 72 h fasting to find serum baseline levels. there was a significant difference in serum glucose, lactate, triglyceride and total protein but not cholesterol, albumin and calcium levels among the treatments. glucose levels increased with fasting tine and reached to a peak after 6 h. then, the glucose level decreas...

Concentrations of Ag, Cu and Zn were studied in muscle and liver of Barbus plebejus, Cyprinus carpio and Leuciscus cephalus from Kilickaya Reservoir. The heavy metal analysis of samples were carried out by using a flame atomic absorption spectrophotometer. The mean heavy metal concentrations of Ag, Cu and Zn were obtained as 1.47±3.44, 1.65±3.31 and 2.89±4.52 μg/g in muscle and 1.78±4.19, 2.07±...

Freshwater fish, Cyprinus carpio were exposed to acute dose of cypermethrin at 7.5 μg/L for 1, 3, 5, 7 and 9 days and sub-lethal concentrations (1.5 μg/L) for 1,7, 14, 21 and 28 days to determine the change in enzyme activity in three functionally different tissues viz., gill, liver and muscle. Cypermethrin induced alterations that are both time dependent and tissue-specific, with glutamate deh...

DEET (N,N-diethyl-m-toluamide) is the most common active ingredient in the insect repellents commonly detected in European groundwater. The aim of this study was to investigate the effect of subchronic DEET exposure on biochemical and haematological parameters, antioxidant enzymes, including catalase, glutathione peroxidase, glutathione reductase, and glutathione S-transferase, and the amount o...
