Effects of relatedness and inbreeding on reproductive success of Nile tilapia (Oreochromis niloticus)

Fessehaye, Y.; Bovenhuis, H.; Rezk, M.A.; Crooijmans, R.; van Arendonk, J.A.M.; Komen, H. (2009)

Type: Journal Article

It is well established that progeny of inbred matings are less fit than those of outbred matings, and that inbred individuals suffer from reduced viability and fertility. Inbreeding can be avoided by dispersal of progeny ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds

Charo-Karisa, H.; Komen, H.; Rezk, M.A.; Ponzoni, R.W.; van Arendonk, J.A.M.; Bovenhuis, H. (2006)

Type: Journal Article

This study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ...
Phenotypic and genetic parameters for body measurements, reproductive traits and gut length of Nile tilapia (Oreochromis niloticus) selected for growth in low-input earthen ponds

Charo-Karisa, H.; Bovenhuis, H.; Rezk, M.A.; Ponzoni, R.W.; van Arendonk, J.A.M.; Komen, H. (2007)

Type: Journal Article

In this study we present estimates of phenotypic and genetic parameters for body size measurements, reproductive traits, and gut length for Nile tilapia (Oreochromis niloticus) selected for growth in fertilized earthen ...
