The International Network on Genetics in Aquaculture (INGA) was established in 1993 and is being coordinated by the International Center for Living Aquatic Resources Management (ICLARM), with the objective to contribute through collaborative research, to the domestication and sustainable performance of tropical finfish species farmed in developing countries and to strengthen national capabilities for genetic enhancement of farmed fish through exchange of germplasm, methodologies and through training and interactive forums. Studies undertaken in recent years for improving breeds of salmon in Norway and tilapia in Philippines by ICLARM and collaborating Philippine and Norwegian institutions, have led to increased awareness among researchers the need for undertaking programs for improvement of breeds of species that are of aquaculture importance in their countries. INGA has been assisting the member countries in developing national breeding programs. This report on Breeding Plan for Mrigal (Cirrhinus mrigala) in Vietnam: Individual (Mass) Selection to Improve Growth Rate is an outcome of such an effort.
