Lock-ins to the dissemination of genetically improved fish seeds
Type: Journal Article
Well-functioning fish seed systems are crucial for human nutrition and improved livelihoods. Yet fish seed systems have received considerably little attention in the diffusion process for genetically improved strains. This ...
Economic performance characterization of intensive shrimp (Penaeus monodon) farming systems in Bangladesh
Type: Journal Article
Intensive shrimp (Penaeus monodon) production system is relatively new in Bangladesh, and has not yet been adequately described or its viability assessed. The aims of this study were to characterize, assess the economic ...
Sex determination in the GIFT strain of tilapia is controlled by a locus in linkage group 23
Type: Journal Article
Tilapias (Family Cichlidae) are the second most important group of aquaculture species in the world. They have been the subject of much research on sex determination due to problems caused by early maturation in culture ...
Heritable variation in swimming performance in Nile tilapia (Oreochromis niloticus) and negative genetic correlations with growth and harvest weight
Type: Journal Article
Nile 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 ...
Inland fisheries critical for the diet quality of young children in sub-Saharan Africa
Type: Journal Article
Animal-source foods (ASF), such as fish, provide a critical source of nutrients for dietary quality and optimal growth of children. In sub-Saharan Africa, children often consume monotonous cereal-based diets, a key determinate ...
Population genomics of an anadromous Hilsa Shad Tenualosa ilisha species across its diverse migratory habitats: Discrimination by fine-scale local adaptation
Type: Journal Article
The migration of anadromous fish in heterogenic environments unceasingly imposes a selective pressure that results in genetic variation for local adaptation. However, discrimination of anadromous fish populations by ...
Governance interactions in small-scale fisheries market chains: Examples from the Asia-Pacific
Type: Journal Article
Small-scale fisheries are subject to various governing institutions operating at different levels with different objectives. At the same time, small-scale fisheries increasingly form part of domestic and international ...
Assessing the Potential for Sustainable Aquaculture Development in Cambodia
Type: Journal Article
Inland capture fisheries are central to livelihoods and food security in Cambodia, but are under threat from growing anthropogenic pressures. Policy discourse in Cambodia increasingly frames aquaculture as a viable alternative ...
How do hunter-gatherers learn? The transmission of indigenous knowledge among the Agta of the Philippines
Type: Journal Article
The Agta of the Philippines depend on extensive knowledge of their natural environment for their livelihoods. However, little is known about the transmission of this indigenous ecological knowledge. This paper examines the ...
A Regional Review of Genetic Resource Access and Benefit Sharing: Key Issues and Research Gaps
Type: Journal Article
Countries are increasingly using access and benefit sharing (ABS) as a legal mechanism to support the conservation and sustainable use of the world’s biological diversity. ABS regulates collection and/or use of genetic ...
