FRS - Reports

The following lists the reports we have produced for clients to date, most of which have been submitted and presented verbally to scientific working groups and management authorities in the respective countries. Note that in both New Zealand and Chile, our estimates of orange roughy biomass from commercial vessels have already been accepted for use in the stock assessments on which management of these fisheries is based
