Resumen
Descripción
This manual, written for extension workers and aquaculturists, deals with methods for selective breeding programmes to improve cultured populations of food fish on medium-sized fish farms. The manual contains chapters on general principles, basic genetics, selection for qualitative phenotypes, selection for quantitative phenotypes, and how to conduct simple selective breeding programmes; a glossary and selected reading list are also included. The principles of quantitative and qualitative geneti cs are explained through examples of tilapia and carp breeding studies. The resources that are necessary for aquaculturists to possess in order to successfully implement selective breeding programmes are discussed and serve to help evaluate the prospects of success before starting a genetic improvement programme.
