Comparison of some traits of economic importance in tilapias (Orechromis niloticus and Sarotherodon galilaeus) with particular reference to their culture in Ghana
Type: Journal Article
This study was conducted to determine which of the two major tilapia species in freshwater capture fisheries in Ghana, Oreochromis niloticus or Sarotherodon galilaeus, is more suitable for breed improvement and pond culture. ...
Heritability of cold tolerance in Nile tilapia, Oreochromis niloticus juveniles
Type: Journal Article
The inability of tilapia to tolerate low temperatures is of major economic concern as it reduces their growing season and leads to over winter mortality. In this study, cold tolerance of juvenile Nile tilapia, Oreochromis ...
Factors affecting early growth of Nile tilapia fry in hapa-in-pond environments
Type: Report
Hapas, usually suspended in fertilized ponds, have long been used for tilapia fry production (Santiago et al., 1985; Bhujel, 1997) and recently for fry rearing. In fish breeding programs, members of a full-sib family usually ...
Fitting growth with the von Bertalanffy growth function : a comparison of three approaches of multivariate analysis of fish growth in aquaculture experiments
Type: Journal Article
Three approaches for multivariate analysis of fish growth in aquaculture experiments with Nile tilapia (Oreochromis niloticus niloticus L.) based on the von Bertalan¡y growth curve are presented and compared. The approaches ...
Genetic parameters and response to selection for live weight in the GIFT strain of Nile Tilapia (Oreochromis niloticus)
Type: Journal Article
Genetic improvement programs can increase the productivity of cultured aquatic species. Their rigorous design requires knowledge about parameters such as herit-ability and correlations among the traits under selection. ...
