Selective breeding for increased body weight in a synthetic breed of Egytian Nile tilapia, Oreochromis niloticus: response to selection and genetic parameters

Selection for harvest weight was performed in a fully pedigreed synthetic line of Nile tilapia (Oreochromis niloticus) in Egypt for two generations. Records were available over three spawning seasons (2002, 2003 and 2004) for weight at the beginning of ...
