Seasonality, labor and integration of aquaculture into southern African smallhold farming systems
Type: Journal Article
Fish production on Malawian smallholdings is generally limited by the quantity and quality of inputs to the pond (Brummett and Noble 1995). The timing of labor availability and other farm activities limit the amount farmers ...
Evaluation of the carcass and commercial characteristics of carps
Type: Journal Article
The role of carcass evaluation techniques in aquaculture research programs, especially in genetics, breeding, production management, feeding and nutrition, cannot be overemphasized. Knowledge of production efficiencies and ...
The farming practices and economics of aquaculture in Thailand
Type: Journal Article
The paper reviews freshwater and coastal aquaculture practices in Thailand, and compares the productivity, costs, and benefits across various types of cultivation and various intensities of production. The paper is based ...
Aquaculture in Jamaica
Type: Journal Article
Jamaica, with its overfish marine resources, has become a major tilapia producer in Latin America led by a small number of large farms practicing tilapia culture with considerable commercial success. Across the country, ...
Fish farming through community partiicipation in Assam
Type: Journal Article
The community tanks and ponds in India are seldom used for fish culture. Fish culture as a community based activity has been shown to be economically viable in some parts of the country. This paper describes the success ...
Integration of aquaculture into smallholder farming systems for improved food security and household nutrition
Type: Journal Article
Aquaculture production techniques based on the culture of low-value herbivorous and/or omnivorous freshwater finfish in inland rural communities, within semi-intensive or extensive farming systems that use moderate to low ...
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 ...
Production of genetically improved organic Nile tilapia
Type: Journal Article

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 ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
Type: Journal Article
This 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 ...
