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 ... -

(2013)Type: ReportOur Coast, Our Future: Western Region of Ghana was the first major product of the Hen Mpoano initiative, published in 2010. It made the case that a process is needed which is grounded in the belief that a fresh approach ... -
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 ... -
Heterogeneous individual growth of Macrobrachium rosenbergii male morphotypes
(2002)Type: Journal ArticleIn a single cohort of small freshwater prawn, Macrobrachium rosenbergii, the size range of females in the population is rather small. However, among the males, three major morphotypes are found and each has a distinct size ... -
Heterosis, direct and maternal genetic effects on body traits in a complete diallel cross involving four strains of red tilapia Oreochromis spp
(2009)Type: Conference PaperHeterosis, direct additive genetic and general reciprocal effects were estimated from a complete diallel cross involving four strains of red tilapia Oreochromis spp from Malaysia, Stirling, Taiwan and Thailand. The mating ... -
Heterotrophic marine bacteria as supplementary feed for larval Penaeus monodon
(1996)Type: Journal ArticleThe findings are presented of a study conducted to use autochthonously obtained, nonpathogenic heterotrophic marine bacteria as a substitute feed for microalgae in rearing larval Penaeus monodon. Eleven strains were isolated: ... -
Hidden benefits and risks of partial protection for coral reef fisheries
(2022)Type: Journal ArticlePartially protected areas are now the dominant global form of spatial management aimed at preserving ecosystem integrity and managing human use. However, most evaluations of their efficacy use only a narrow set of conservation ... -
Hidden harvest: The global contribution of capture fisheries
(2012)Type: ReportThe important contribution of fi sheries to human well-being is frequently underestimated. This report highlights that contribution. The report focuses on small-scale fi sheries and developing countries because the livelihoods ... -
High level of hybridisation in three species of Indian major carps
(2004)Type: Journal ArticleThirty individuals of each species of Indian major carps, i.e., Catla catla, Cirrhinus cirrhosus (C. mrigala) and Labeo rohita, obtained from a nursery near Mymensingh, Bangladesh were analysed by means of allozyme ... -
High yields but still questions: three years of animal-fish farming
(1980)Type: Journal ArticleThe CLSU/ICLARM Integrated Animal-Fish Farming Project at Central Luzon State University, Nueva Ecija, Philippines, is approaching the end of its third year. During this time, ponds and animal houses have been constructed ... -
A high-quality chromosome-level genome assembly of rohu carp, Labeo rohita, and its utilization in SNP-based exploration of gene flow and sex determination
(2023)Type: Journal ArticleLabeo rohita (rohu) is a carp important to aquaculture in South Asia, with a production volume close to Atlantic salmon. While genetic improvements to rohu are ongoing, the genomic methods commonly used in other aquaculture ... -
Higher fish but lower micronutrient intakes: Temporal changes in fish consumption from capture fisheries and aquaculture in Bangladesh
(2017)Type: Journal ArticleThis study shows people in Bangladesh are now eating 30% more fish than they did 20 years ago, but they are getting a smaller amount of important nutrients from it. The results challenge the conventional narrative that ... -
