Genetic parameter and genotype by environment interaction for body weight of Oreochromis shiranus
(2006)Type: Journal ArticleGenetic and phenotypic parameter estimates for tagging and harvest body weights were obtained from the F1 base (377 offspring of 59 full-sib families), F2 (1241 offspring of 52 full- and 33 half-sib families) and F3 (1052 ... -
Mating systems and male reproductive success in Nile tilapia (Oreochromis niloticus): a microsatelite analysis
(2006)Type: Journal ArticleFry production in Nile tilapia, Oreochromis niloticus is typically achieved by mass spawning of males and females stocked in large hapas suspended in ponds. In such spawning aggregations, territorial behavior and reproductive ... -
Fish supply and demand for food security in Sub-Saharan Africa: An analysis of the Zambian fish sector
(2018)Type: Journal ArticleThe demand for fish in Sub-Saharan Africa, as driven by the trend of diet-shift to fish, economic and demographic growth, outstrips supply. The resulting fish deficit is drawing attention of policy makers as it poses threats ... -
Enhancing social resilience of the coastal fishing communities: A case study of hilsa (Tenualosa ilisha H.) fishery in Bangladesh
(2018)Type: Journal ArticleSocial resilience is an essential aspect of sustainability in environmental management, especially in poor resource-dependent communities. To better understand the dynamics of social resilience, we have conducted a primarily ... -
Influence of phenol pollution on Nile tilapia (Oreochromis niloticus)
(2007)Type: ReportIn this study a field investigation was done by collection of water and Nile tilapia (Oreochromis niloticus) from Helwan (branch of Nile River), El- Abbassa earthen ponds and Bahr El-Baqar fish ponds every 4 months during ... -
Pioneering fish genetic resource management and seed dissemination programmes for Africa: adapting principles of selective breeding to the improvement of aquaculture in the Volta Basin and surrounding areas
(2007)Type: ReportThis document represents the report and contributed papers from a workshop of the same name. The workshop was comprised of a group of 30 international experts and representatives of the environmental, fisheries and policy ... -
Strategies to enhance the role of fishponds in farming systems
(2007)Type: Book ChapterThis book chapter discusses the identified problems at the level of the fish, the pond and the farm. Such areas as food safety, diversificaiton, development of IAA systems interdisciplinary research as a tool are elaborated, ... -
Effect of Echinacea on body gain, survival and some hematological and immunological parameters of Oreochrmis niloticus and their response to challenge infection
(2007)Type: Journal ArticleSix hundred and forty O. niloticus were equally distributed in 16 hapas (each of 1.5 m3) to be used for 4 treatments in 4 replicates. Fish of groups 1-3 were fed on basal diet mixed with Echnicacea (0.25 ppt) for 1 st, 2 ... -
Mass spawning of Oreochromis niloticus for fry production: threats and opportunities for small-scale aquaculture and selective breeding
(2007)Type: Book ChapterMass selection based on mass spawning can present a feasible and low-cost selective breeding scheme. In mass spawning, however, mating is not controlled and a small number of breeding individuals may account for a ... -
Decentralised Nile tilapia seed production
(2007)Type: Book ChapterLocal production of mixed sex Nile tilapia in irrigated rice fields has been introduced, established and then spread through farmer-to farmer contact in Northwest Bangladesh benefiting poor households in a number of ways. ... -
The role of species and systems in the development and growth of aquaculture in Asia: needs and prospects
(2007)Type: Book ChapterThis paper reviews the current practices in Asian aquaculture and emerging trends in species and systems against a backdrop of changing structure of demand, supply and trade. It examines key issues concerning the role of ... -
Indigenous species for African aquaculture development
(2007)Type: Book ChapterFrom the history of introductions and the development of successful aquaculture elsewhere, it appears that the use of exotic species to speed up the rate of aquaculture development in Africa is unlikely to be an efficacious ... -
Breeding program requirements in developing countries may differ depending on circumstances
(2007)Type: Book ChapterAquaculture in developing countries is largely based on unimproved fish strains. There is ample evidence indicating the potential of genetic improvement programs and a range of selection methods may be used. Examples of ... -
Effect of some immunostimulants as feed additives on the survival and growth performance of Nile tilapia, Oreochromis niloticus and their response to artificial infection
(2007)Type: Journal ArticleFour plant based immunostimulants (Echinacea purpurea 0.25 and 1.0 ppt, Allium sativum 3 %, Nigella sativa 3% and Origanum marjorana 2 and 3% and mixture of Allium sativum , Nigella sativa 3:1, 1:3 and 3:3%, respectively ... -
Roles of ponds in integrated agriculture-aquaculture systems
(2007)Type: Book ChapterThe effects of adding an aquaculture pond to existing farming operations on nutrient use efficiency and productivity were explored. Ponds can be used to cycle nutrients from agricultural by-products such as manures and ... -
Selecting Nile tilapia (Oreochromis niloticus) for growth in low-input environments
(2007)Type: Book ChapterThis chapter presents the results from a selective breeding experiment with Nile tilapia in a low input pond environment. The environment was defined as low input as the pond only received chicken manure for fertilisation. ... -
Fishponds in farming systems
(2007)Type: BookThis book is a collection of refereed papers on a controversial subject in agricultural development. Arguing that sustainability of fish culture in ponds needs a new paradigm - feed the pond to grow fish - two chapters ... -
Relevance of a rapid appraisal approach to identify locally available feed ingredients to small-scale Nile tilapia (Oreochromis niloticus L.) aquaculture
(2007)Type: Journal ArticleApplications of a rapid appraisal approach to identify locally available feed ingredients in feed formulation, production, and socio-economics of Nile tilapia aquaculture in Bangladesh are discussed. Three diets of 35%, ... -
