New Tools for Assessing Fish Stock Impacts - Bayesian Decision Networks (BDNs)

How many redfish must there be to sustain the Western Atlantic redfish fishery? Powerful computer tools are being developed to help answer that question. Due to poor recruitment (productivity), the Western Atlantic redfish fishery (unit 1+2) has not recovered since it was closed in 1995.

Fisheries and Oceans Canada (DFO) is providing the University of British Columbia Institute for the Oceans and Fisheries with $27,000 to use new computer tools (called Bayesian Decision Networks (BDNs)) to better assess the ecological factors impacting the productivity of the Western Atlantic redfish fishery.

The information obtained from this research may help inform how to best support the recovery of redfish populations.
