Age and growth of three species of Lake Victoria fish determined by means of otolith daily growth rings
Type: Journal Article
The sagittal otoliths of Lates niloticus, Haplochromis obesus, and Oreochromis niloticus from Lake Victoria were examined for daily growth rings using scanning electron microscopy. In the three species the increments were ...
Analysis of research for the development of tilapia farming: an interdisciplinary approach is lacking
Type: Journal Article
Tilapias, particularly Oreochromis spp., are farmed throughout the tropics and subtropics but most of the production comes from a few Asian countries. Global production increased by about 13%/yr from 1985 to 1989. A global ...
Polyculture of carps in integrated broiler-cum-fishfarming systems
Type: Book Chapter
A study was undertaken to determine fish species combinations that would result in optimum production levels in integrated broiler raising systems. Its objectives were: (i) to evaluate the production potential of fish in ...
The use of napier grass (Pennisetum purpureum) and maize (Zea mays) bran as low-cost tilapia aquaculture inputs
Type: Journal Article
The objective of this study was to determine the effect of napier grass presented in various forms either alone or combined with maize bran and/or lime on the growth of T. rendalli, 0. shirunus and 0. kurongue.
WESTERN blot analysis of plasma components of the three Tilapia species, Oreocbromis aureus, O. niloticus and Sarotherodon galilaeus
Type: Journal Article
In past studies erformed to differentiate among commercially important species of the Tilapia group, erythrocytes o the different species were successfully investigated in agglutination tests with lectins and Tilapia ...
The Genetic Improvement of Farmed Tilapias (GIFT) project: the story so far
Type: Journal Article
This issue of Naga features three articles about a project on the Genetic Improvement of Farmed Tilapias (GIFT) and a related article on the trend to genetic deterioration in some carp hatcheries. The first is on the genesis ...
Effect of transportation stress on hepatic glycogen of Oreochromis niloticus (L.)
Type: Journal Article
Oreochromis niloticus was subjected to transportation stress to investigate hepatic glycogen levels and mortality as indices of stress. Mortalities lasted up to three days after transportation, except in highly aerated ...
Breeding plan for Nile tilapia (Oreochromis niloticus) in Indonesia: individual selection
Type: Report
The International Network on Genetics in Aquaculture (INGA) was established in 1993 with the objective to contribute through collaborative research, to the domestication and sustainable performance of tropical finfish ...
Simulation of the effects of oxygen on food consumption and growth of Nile tilapia, Oreochromis niloticus (L.)
Type: Journal Article
Fish need oxygen for aerobic generation of energy for body maintenance, locomotion, feeding and biosynthesis. The rate of oxygen uptake of most fish is limited by diffusion through the gills, and gill surface area grows ...
Socioeconomic impact and farmers' assessment of Nile tilapia (Oreochromis niloticus) culture in Bangladesh
Type: Report
The book reports on the socioeconomic study made on tilapia culture in seasonal ponds/ditches in Bangladesh. Results show that the simple technology, requiring very low labor input, is economically viable and brings other ...
