For the Vietnamese government the growth of reservoir fisheries in the north mid highland area is a high priority. It is expected development of reservoir fisheries in highland areas will provide employment opportunities, improve living standards, and increase fish consumption in regions which are considered extremely poor and protein malnourished. The aim of this project is firstly, to determine the most suitable nursing method of fry to fingerling rearing of two species of carp, secondly, to evaluate the suitability of the two largest reservoirs in the region and thirdly, to develop suitable stocking and husbandry strategies to optimise fish yields.
