Profitability and adoption of improved shrimp farming technologies in the aquatic agricultural systems of southwestern Bangladesh
Type: Journal Article
This paper assesses factors influencing adoption of new shrimp aquaculture technologies within aquatic-agricultural farming systems in southwestern Bangladesh. The impacts of three new technologies were assessed: two ...
Beyond net deficits: new priorities for an aquacultural geography
Type: Journal Article
Geographers first identified aquaculture as an important field of study during the 1990s, pointing to a 'net deficit' in geographical knowledge about the activity. This paper examines how far geographers have come in ...
Cage-pond integration of African catfish (Clarias gariepinus) and Nile tilapia (Oreochromis niloticus) with carps
Type: Journal Article
Cage-pond integration system is a new model for enhancing productivity of pond aquaculture system. A field trial was conducted using African catfish (Clarias gariepinus) and Nile tilapia (Oreochromis niloticus) in cages ...
Does aquaculture add resilience to the global food system?
Type: Journal Article
Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, the authors explore how current interconnections ...
Effects of stocking density on production and economics of all-male tilapia (Oreochromis niloticus) culture in a rain fed rice-fish ecosystem
Type: Journal Article
Effects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate ...
The socio-economic context for improving food security through land based aquaculture in Solomon Islands: A peri-urban case study
Type: Journal Article
Future fish demand-supply scenarios project that investment in aquaculture will be needed to ensure fish for food security in Solomon Islands. In 2010 a study of two peri-urban areas of Solomon Islands analysed the demand ...
Performance of the Genetically Improved Farmed Tilapia (GIFT) strain over ten generations of selection in Malaysia
Type: Journal Article
A selection programme using Best Linear Unbiased Prediction (BLUP) method for the estimation of genetic merit was implemented by the Department of Fisheries Malaysia (DOF) in collaboration with the WorldFish Centre. This ...
Response to selection for growth in an interspecific hybrid between Oreochromis mossambicus and O. niloticus in two distinct environments
Type: Journal Article
The development of a saline tolerant tilapia strain able to grow fast is of importance in the Philippines, where 240 000 ha of brackish water ponds are available. To this end, founder hybridization between Oreochromis ...
Indirect genetic effects and inbreeding: Consequences of BLUP selection for socially affected traits on rate of inbreeding
Type: Journal Article
Social interactions often occur among living organisms, including aquatic animals. There is empirical evidence showing that social interactions may genetically affect phenotypes of individuals and their group mates. In ...
Genetic improvement of Israeli blue (Jordan) tilapia, Oreochromis aureus (Steindachner), through selective breeding for harvest weight
Type: Journal Article
Genetic parameters and selection responses were obtained for harvest body weight of blue tilapia (Oreochromis aureus) from data collected over three generations in a selected population. A total of 18 194 records representing ...
