Recent studies show that local consumer demand for fish will continue to increase in Viet Nam. At the same time, the export-oriented fish processing industry will see a growing need for raw materials. These substantial future demands for safe and high-quality fish products can only be met if efficient marketing arrangements are established. This paper identifies a number of constraints in the current domestic fish market, which form the basis for recommendations to improve the present marketing arrangements in Viet Nam. The paper also explores how credit is widely used for financing marine capture fisheries, particularly offshore fishing and export-oriented fish culture, processing and marketing in Viet Nam. State-owned financial institutions play a major role in financing capital expenditure while working capital requirements are mainly met by informal sources of credit. However, future investment requirements and credit needs are greater than currently available.
