Diet and dietary habits of African Butter Catfish Schilbe mystus (Linne, 1766), an economically important fish in Oyan and Asejire lakes (southwest Nigeria) were examined between July 2000 and December 2001. Stomach contents were analysed using the numerical, frequency of occurrence and points methods. The fish is predatory but the diet differs among lakes and seasons. Insects were more importa...

Concentrations of metals were determined in four species of anchovy (Coilia sp.) from the Yangtze River, Taihu Lake, and Hongze Lake in Jiangsu Province, China. Concentrations of Cr in anchovy fish muscle ranged from 2.6 × 10(-2) to 5.0 mg/kg ww, and Coilia nasus taihuensis in Jiaoshan, Taihu Lake contained the highest concentrations of Cr, which was almost 111-fold higher than the mean value a...

The Department of Rural Health, University of Melbourne, has developed a framework for conducting research in partnership with Indigenous communities. The framework addresses past inappropriate research practices, incorporates cultural understandings, and outlines culturally appropriate protocols. The four parts of the framework are a committee to initiate, direct and oversee all research proje...

From the last decade the pond has been suffering from the resource of water due to decline rain fall, variable climate, and geologic conditions. Thus, so many of areas of the India suffer from severe water shortage like Chhatarpur. Ichthyodiversity increases the economic success of the fisheries pond and implies that the area has become more efficient. A fish are not only useful as source of fo...

The fossil record of centrosaurine ceratopsids is largely restricted to the northern region of western North America (Alberta, Montana and Alaska). Exceptions consist of single taxa from Utah (Diabloceratops) and China (Sinoceratops), plus otherwise fragmentary remains from the southern Western Interior of North America. Here, we describe a remarkable new taxon, Nasutoceratops titusi n. gen. et...

A systematic investigation was conducted in Lake Taihu in autumn of 2013 and 2014, in order to understand the environmental fate of microcystins (MCs) and evaluate the health risk from MCs. Samples of water, algal cells, macrophytes, shrimps and fish were taken to detect MCs by HPLC-MS/MS after solid phase extraction. Widespread MC contamination in water, algal cells, macrophytes, shrimps and f...

Secondary succession is impacted by both biotic and abiotic forces, but their relative importance varies due to environmental drivers. Across estuarine salinity gradients, physical stress increases with salinity, and biotic stresses are greater at lower salinities. In southern New England tidal marshes spanning a landscape-scale salinity gradient, we experimentally examined the effects of physi...

The present work focused on role of the immune organ in the thymus of Mystus gulio. Haemopoietic tissue was found mainly in the spleen, head kidney, thymus and a small amount occurred in the mesonephros. The clearance of the intraperitoneally injected colloidal carbon was carried out. The phagocyte uptake of carbon, after its intraperitoneal injection. It was first detected in the thymus at 30 ...
