Heavy metal and faecal bacterial contamination of urban lakes in Yaounde, Cameroon
(2003)Type: Journal ArticleThe objective of this study was to measure the concentration of indicator bacteria and heavy metals in fish, mud and water of the two largest urban inland valleys in Yaounde. -
Heavy metal contamination in surface water and sediment of the Meghna River, Bangladesh
(2017)Type: Journal ArticleThe present study was designed to evaluate the temporal variation of ten metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn) in the surface water and sediments of the Meghna River, Bangladesh during rainy, winter and pre-monsoon ... -
Heavy metals concentrations in water and fish of some Egyptian lakes and fish ponds
(2005)Type: Journal ArticleFive heavy metals namely, cadmium, copper, iron, lead, and zinc were determined in water and fish samples obtained from three different lakes and fishponds in Egypt over nine months to assess pollution with those toxic ... -

Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
(2006)Type: Journal ArticleThis study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ... -
Heritability of cold tolerance in Nile tilapia, Oreochromis niloticus juveniles
(2005)Type: Journal ArticleThe inability of tilapia to tolerate low temperatures is of major economic concern as it reduces their growing season and leads to over winter mortality. In this study, cold tolerance of juvenile Nile tilapia, Oreochromis ... -
Heritable variation in swimming performance in Nile tilapia (Oreochromis niloticus) and negative genetic correlations with growth and harvest weight
Type: Journal ArticleNile tilapia is predominantly produced in smallholder ponds without aeration. We hypothesize that Nile tilapia with high oxygen uptake efficiency (O2UE) may perform better under these conditions than Nile tilapia with low ... -
