T doubling salmon catches on the Pacific coast An ambitious program involving Some of the basic premises on which the construction of hatcheries, artificial spawning Salmonid Enhancement Program was based channels and other enhancement works was have proven to be faulty. One was that salmon expected to generate significant economic production could not be restored through better benefits and the cost was to be recovered from management of wild stocks; improvements in those who catch the fish. managing fishing have since increased catches of wild salmon by more than the increase in Over the last 17 years some $526 million enhanced production. Another was that the has been spent. A substantial enhancement technology of enhancement was proven; it has capability, consisting of more than 300 since been revealed as uncertain and risky. A facilities, is now in place. They contribute about third was an assumption that government would 14,000 metric tonnes, or roughly 13 percent, of take steps to prevent further unnecessary the annual catch of salmon. In addition, the investment in commercial fishing capacity., but Salmonid Enhancement Program has established no new measures were taken. A fourth was an significant programs in education, public assumption that the costs would be recovered information, native development and research from those who catch the fish, but only token related to enhancement efforts were made to do so. Enhanced production has fallen signifi The analysis indicates that the economic cantly short of original expectations, mainly outlook for future enhancement is, potentially, for two reasons. One is funding at lower levels much brighter. With the facilities in'place, and than expected. The other is the shift in their capital costs already expended, the priorities, in the 1980s, from cost-efficient prospective benefits exceed the prospective production in large-scale spawning channels costs over the facilities' remaining life. More for sockeye and hatcheries for chum salmon over, the economic performance of facilities to costly attempts to restore depressed wild varies widely, and termination of those that fail stocks, especially coho and chinook. to meet minimal standards of cost-efficiency would significantly improve the overall results. The economic achievements have been There appears to be promising opportunities in disappointing as well. The estimated lifetime . additional salmon enhancement and habitat cost of constructing and operating the development projects also. enhancement facilities built under the Salmonid Enhancement Program exceeds the estimated To take advantage of these oPIX>rtunities, benefits by $592 million, indicating a benefit major changes are needed. Enhancement must cost ratio of .6 for the program as a whole. The be reconciled with the conservation of wild unquantified benefits of education, research and salmon; in particular, wild stocks must be other non-production activities are not likely to protected from potential damage from enhanced stocks. A much stronger base of scientific support and project assessment must be provided. The planning and operation of enhancement works must be subjected to more rigorous economic tests. And the beneficiaries must take more responsibility for organizing and financing the enhancement effort. These requirements call for a thorough overhaul of the enhancement program. A suggested new approach involves a gradual transfer of responsibilities for enhancement from the Department to an independent, non profit corporation, controlled and financed primarily by the beneficiaries in the fishing community. The proposed corporation would raise its revenues from those who catch the fish and manage existing and new enhancement facilities with a view to generating maximum benefits for the fishing interests it represents. It would also be empowered to enter into agreements with local fiShing and other organizations to take over enhancement facilities and develop new ones. These general proposals are intended to focus discussion between government and private interest groups, with a view toward identifying the most promising and acceptable approach for a renewed enhancement program. ii '---I CONTENTS Page Executive Summary........ ... .................... ........... ............ ...... .......... ........ .......... ... ........... .... i Contents ...................................................................................................... 0.G................... iii Pr'eface 0 ..................... , •••••••••••• I ••• I •••••••• e, •• o. t ••• t ••• f •••• 0 tf •••••••••• 0 •••••••• t ••••• f.
