Performance and nature of genetically improved carp strains in Asian countries
Type: Journal Article
The WorldFish Center and its research partners have recently made efforts to develop genetically improved carp strains. This paper analyses the comparative performance of the genetically improved carp strains on both average ...
Inclusive aquaculture: business at the bottom of the aquatic pyramid
Type: Journal Article
Through a SIDA -funded project on small-scale fisheries FAO and partners have been supporting WorldFish Center research into small-scale aquaculture investment. Studies of projects in Bangladesh, India and Indonesia suggest ...
Differences in sexual size dimorphism among farmed tilapia species and strains undergoing genetic improvement for body weight
Type: Journal Article
Many tilapia (Oreochromis spp.) farmers produce all-male populations because of the superior growth rate of males compared to females. To investigate differences in body weight at harvest of males and females among different ...
Identifying hotspots for antibiotic resistance emergence and selection, and elucidating pathways to human exposure: Application of a systems-thinking approach to aquaculture systems
Type: Journal Article
Aquaculture systems are highly complex, dynamic and interconnected systems influenced by environmental, biological, cultural, socio-economic and human behavioural factors. Intensification of aquaculture production is likely ...
Fish and the nutrition of rural Cambodians
Type: Journal Article
In Cambodia, fish is a central source of food for the rural poor due to its abundance and availability, and contributes greatly to national food security. In this paper, we review how fish is a staple food, provides quality ...
Quantitative genetic parameter estimates for body and carcass traits in a cultured stock of giant freshwater prawn (Macrobrachium rosenbergii) selected for harvest weight in Vietnam
Type: Journal Article
Benefits derived from selective breeding have been demonstrated in livestock and in some fish species, but by contrast, there have been few systematic selection programs reported for shrimps. Improving growth rate has been ...
Moving beyond the shrimp farm: Spaces of shared environmental risk?
Type: Journal Article
Key environmental challenges faced by the aquaculture sector demonstrate that aquaculture production is not isolated from the surrounding environment, and we see a policy shift towards area-based approaches. However, without ...
A comparison of communal and separate rearing of families in selective breeding of common carp (Cyprinus carpio): Responses to selection
Type: Journal Article
The genetic response in growth traits in a selection program for increased harvest weight in a common carp population in Vietnam is reported. A base population (G0) was established from six carp stocks using single pair ...
Measuring individual feed efficiency and its correlations with performance traits in Nile tilapia, Oreochromis niloticus
Type: Journal Article
Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets ...
Microbial biomass (Novacq™) stimulates feeding and improves the growth performance on extruded low to zero-fishmeal diets in tilapia (GIFT strain)
Type: Journal Article
Worldwide tilapia production is rapidly growing and becoming increasingly reliant on the provision of cost-effective sustainable formulated feeds. In the paper, the authors assessed the capacity for various inclusion rates ...
