Talk overview l.jpg

Talk Overview

  • What would the ultimate management system be?

  • Where are we now?

  • What technologies are available to move us forward?


The ultimate fisheries management system l.jpg

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


Current fisheries management l.jpg

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
