Fisheries Bioengineering Symposium PDF Download

The 1988 Fisheries Bioengineering Symposium, held in Portland, Oregon, USA, was based on a theme of "Problems and Solutions in Developed River Systems." The emphasis was upon developed river systems both because development is more the norm than nondevelopment and because the seemingly worst problems-hence, the biggest challenges-for fish in rivers result from development. Further, one can reasonably predict that development will continue, so unless adequate solutions are found, river-based fisheries will experience progressiverly greater problems. Most of the symposium was deveoted to solutions in two main and widely divergent topics: habitat improvement and restoration, and mitigration via hatcheries. Although these topics may seem strange bedfewllows, they define the main alternatives available to fishery managers for correcting or mitigating fishery losses in developed rivers, and they are the professional concerns of bioengineering. In this regard, it was a primary goal of the sterring committee to bring together and facilitate information exchange between biologist and engineers so that each group could gain a better appreciation for the other's perspectives, constraints, and strengths.
