Genetic quality of cultured tilapia stocks in Africa
Type: Journal Article
African aquaculture is poised for rapid expansion. However, one of the key constraints holding back growth of the sector is the poor quality of the fish stocks available for culture. The problems of declines in growth ...
Training Manual on improved carp/carp-shing poly culture in pond and dyke cropping
Type: Manual
Due to inadequate technical knowledge and training in advanced methods of gradually growing carp poly culture, framers are not getting expected yield. From the very beginning of the CSISA-BD project, WoldFish Center has ...
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 ...
Heterosis, direct and maternal genetic effects on body traits in a complete diallel cross involving four strains of red tilapia Oreochromis spp
Type: Conference Paper
Heterosis, direct additive genetic and general reciprocal effects were estimated from a complete diallel cross involving four strains of red tilapia Oreochromis spp from Malaysia, Stirling, Taiwan and Thailand. The mating ...
Influence of fertilizers' types and stocking density on water quality and growth performance on Nile tilapia African catfish in polyculture system
Type: Conference Paper
The effects of fertilizer types and stocking density were investigated on water quality parameters that expected to affect growth performance of the polyculture of Nile tilapia <i> (Oreochromis niloticus) </i>, African ...
Echinacea purpurea and Allium sativum as immunostimulants in fish culture using Nile tilapia (Oreochromis niloticus)
Type: Journal Article
This study aimed to evaluate and compare the efficiency of echinacea and garlic-supplemented diets as immunostimalants after different periods of application and after 4-month of withdrawal on some haematological and ...
Effect of garlic on the survival, growth, resistance and quality of Oreochromis niloticus
Type: Conference Paper
Study was conducted to evaluate the efficiency of the garlic in improving the immune response, survival, growth and disease resistance in Nile tilapia <i>(O. niloticus)</i>. The effects on quality and shelf life of fish ...
Concepts, alternatives, and environmental considerations in the development and use of improved strains of tilapia in African aquaculture
Type: Journal Article
The status of African populations of farmed tilapia is reviewed and discussed in light of the need for improved strains for commercial aquaculture. Many tilapia populations currently held on African fish farms have been ...
Value chain analysis: shrimp, prawn and tilapia from the southern region of Bangladesh & feasibility analysis: brackish water sea-bass in the southern region in Bangladesh
Type: Report
The WorldFish Center is implementing the FtF Aquaculture Project in 20 southern districts in Bangladesh. The project is implemented under USAID’s Feed the Future initiative in collaboration with the Government of Bangladesh. ...
Growth and survival rate of three genetic groups fed 28% and 34% protein diets
Type: Journal Article
The strain by nutrition interaction in body weight and survival rate was examined by testing three genetic groups (Selection and Control lines of the GIFT strain, and Red tilapia) at two levels of protein in the diet (28% ...
