There has been an extraordinary evolution of the management program in Bristol Bay for natural sockeye salmon (Oncorhynchus nerka) stocks that has coincided with a roughly two-fold increase in sustainable harvest level. During this evolution there has been a continuous expansion of projects to assess the stocks and monitor fisheries. Escapement goals were continuously revised as warranted by the emerging data, and management has become more accurate and precise. Computer simulations showed how changes in harvest policy and reductions in management error can increase the sustainable yield of these fisheries. These benefits and costs were expressed as the ratio of present value of the incremental increases in sustainable harvests to the incremental cost of the program. The ratio of benefits to costs, resulting from investment in the program of management and research, was approximately 10 in 1984.
