Measuring individual feed efficiency and its correlations with performance traits in Nile tilapia, Oreochromis niloticus
Type: Journal Article
Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets ...
Species composition in the Molobicus hybrid tilapia strain
Type: Journal Article
The “Molobicus” hybrid breeding programme was initiated to improve tilapia growth performance in brackish water. The base population was created by backcrossing F1 Oreochromis niloticus GIFT strains × feral O. mossambicus ...
Genetic variation in wild populations and farmed stocks of Nile tilapia (Oreochromis niloticus) in Madagascar
Type: Journal Article
Four farmed stocks and four wild populations of Nile tilapia (Oreochromis niloticus), which was first introduced to Madagascar sixty years ago, were assayed for genetic variation at nine microsatellite loci to determine ...
Agonistic behaviour and feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
The main hypothesis of the present study was that an aggressive and dominant fish would eat more feed and would be more efficient. To test this hypothesis, estimations of the relationships between agonistic behaviour, ...
Quantifying the genetic parameters of feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
Improving feed efficiency in fish is crucial at the economic, social and environmental levels with respect to developing a more sustainable aquaculture. The important contribution of genetic improvement to achieve this ...
