Technical efficiency of freshwater pond polyculture production in selected asian countries : estimation and implication
Type: Journal Article
The research documented in this article estimates the levels and determinants of farm-level technical efficiencies (TE) in freshwater pond polyculture systems in China, India, Thailand, and Vietnam. The levels of ...
Population structure and genetic variability of six bar wrasse (Thallasoma hardwick) in Northern South China revealed by mitochondrial control region sequences
Type: Journal Article
The genetic relationships among northern South China Sea populations of the six bar wrasse (<i>Thallasoma hardwicki</i>) were investigated. Fish collected from the Solomon Islands were used for geographic comparison. In ...
Integration of aquaculture into crop-animal systems in Asia
Type: Journal Article
The status of integrated agriculture-aquaculture (IAA) in Asia is reviewed, with an emphasis on rural small-scale systems. Existing IAA systems within mixed farming systems are characterised and the economic and ecological ...
Farm-economics of genetically improved carp strains in major Asian countries and carp seed price policy model
Type: Journal Article
The study has conducted the micro level analysis of hatchery operators, fishseed-rearing farmers and carp farmers with respect to their socio-economic characteristics, infrastructural development, husbandry practices and ...
Status and economics of freshwater aquaculture in selected countries of Asia
Type: Journal Article
The paper discusses the status of freshwater aquaculture, and the productivity and cost effectiveness of alternative technologies in the major fish producing countries in Asia, such as Bangladesh, China, India, Indonesia, ...
Genetic diversity and selective breeding of red common carps in China
Type: Journal Article
China has a very rich genetic diversity in common carp (Cyprinus carpio) and the red common carp plays an important role in Chinese aquaculture and genetic studies. Selective breeding, particularly crossbreeding has been ...
Genetic improvement of the herbivorous blunt snout bream (Megalobrama amblycephala)
Type: Journal Article
Selection experiments with the herbivorous blunt snout bream or Wuchang bream (Megalobrama amblycephala) were started in 1985. Mass selection for size and length/depth ratio resulted in a significant increase in growth and ...
