Selecting Nile tilapia (Oreochromis niloticus) for growth in low-input environments
Type: Book Chapter
This chapter presents the results from a selective breeding experiment with Nile tilapia in a low input pond environment. The environment was defined as low input as the pond only received chicken manure for fertilisation. ...
Barriers to aquaculture development as a pathway to poverty alleviation and food security
Type: Conference Paper
The importance of aquaculture production in developing countries is reviewed briefly. Two sets of barriers to realizing the potential of aquaculture to alleviate poverty and improve food security and nutrition are identified: ...
Small-scale aquaculture: Global and national perspectives
Type: Conference Paper
Fish has been a staple food for over a billion people. Its demand is increasing due to growing population and awareness about health benefits of aquatic animal food. Disappointingly, wild catch worldwide is on the decline ...
In the spotlight: Kelvin Mashisia Shikuku
Type: Blog
WorldFish scientist Kelvin Mashisia Shikuku sits down for a Q&A to discuss his research on scaling and disseminating aquaculture innovations to rural fish farmers.
Observations on intergeneric hybrids in tilapias
Type: Conference Proceedings
This study describes the hatchability, growth, sex ratios and reproductive behavior of intergeneric hybrids between Tilapia zillii (Linneus) and Sarotherodon galilaeus (Linneus), and between T. zillii and Oreochromis ...
Echinacea as immunostimulatory agent in Nile tilapia (Oreochromis niloticus) via earthen pond experiment
Type: Conference Paper
The study aimed to investigate the effect of Echinacea on survival and growth rates of Nile tilapia (Oreochromis niloticus), its immunostimulatory and disease control effects via changes in various hematological and ...
Progress towards providing Fijian farmers with a better tilapia strain: evaluation of the GIFT fish in Fiji
Type: Journal Article
The relative growth performance of the GIFT strain Nile Tilapia (Oreochromis niloticus) was compared under integrated and non-integrated conditions with the best performing ‘indigenous’ Fijian tilapia strain, O. niloticus ...
Estimation of genetic change in the GIFT strain by comparing contemporary progeny produced by males born in 1991 or 2003
Type: Conference Paper
During the development of the GIFT (Genetically Improved Farmed Tilapia) strain in Philippines sperm was frozen from a sample of males from founder stocks and subsequent generations. In this paper a comparison of progeny ...
Lake of flies, or lake of fish? A tropic model of Lake Malawi
Type: Journal Article
Ecosystem-focused models have, for the first time, become available for the combined demersal and pelagic components of a large tropical lake ecosystem, Lake Malawi. These provide the opportunity to explore continuing ...
Investigations on the use of on-farm resources as pond inputs to culture Tilapia rendalli and Oreochromis shiranus on smallholder farms in rural Malawi
Type: Journal Article
Resources available on the majority of smallholder fish farms in the Zomba District of Malawi were tested toincrease smallholder aquaculture production currently limited by a lack of inputs.
