Abstract:The economic viability of a Japanese flounder stock enhancement program initiated in 1983 was investigated in Hokkaido, Japan. Specific costs and benefits of the 20-year venture were calculated through 1989 and estimated for future years. Net present value (NPV) calculations, benefit-cost ratio (B/C) analysis, and corresponding sensitivity analyses were conducted to evaluate the project's net economic returns to Ishikari Bay flounder fishermen. Results suggest the program would generate a NPV over $2 million with a B/C of 3.15. Sensitivity analysis revealed the highest return on future project investment would come from research on improving fry survival after release. This investigation indicates economic viability need not be sacrificed to accomplish biologically successful stock enhancement programs.
