  1. Technologies For More Efficient Fisheries Presented at the Fourth North Pacific RimFisheries Conference, Tokyo, Japan, April 23, 1997. Scientific Fishery Systems, Inc. Patrick K. Simpson President P.O. Box 242065 Anchorage AK 99524 907/345-7347 907/345-9769

  2. Talk Overview • What would the ultimate management system be? • Where are we now? • What technologies are available to move us forward?

  3. The Ultimate Fisheries Management System • On-Demand Reporting by all Fish • Selective Fish Harvesting • Accurate, On-Demand Vessel Report • Accurate, Immediate Habitat Assessment • Perfect Modeling of Fish Dynamics

  4. Current Fisheries Management • Sparse, Periodic Sampling of Fish Stocks • Semi-Selective Harvesting; Bycatch Remains a Problem • Periodic Vessel Reporting; Uneven Accuracy of Reports • Sparse, Aperiodic Habitat Assessment • Crude Models of Fish Dynamics

  5. Moving Forward • Improved Data Collection • On-Board • Remotely Sensed • Information Processing • Spatial Analysis • Automatic Model Generation • Communications

  6. Improved Data Collection:On-Board • Fish Species Identification • Long-Range School Detection • Automated On-Board Stock Categorization • Rapid Temperature Profiling • Bottom-Type Classification
