surveys typically account for a very high proportion of the cost associated
with fisheries data collection for assessment and advice. They also
provide potentially the most useful and unbiased information on stock
development, recruitment, exploitation, population characteristics and
distribution. It is important therefore to maximize the utilization of
this information in the assessment and advisory process. Survey data are often
imprecise, so it is essential to consider creative ways to improve survey
precision whenever possible.
role is to bridge any communication gaps that may
exist between survey planning and assessment working groups. WGISDAA’s aim is
to highlight best practice in the design, analysis, presentation,
communication, integration and interpretation of surveys and survey
information. Data-limited stocks, deteriorating fishery dependent data,
survey design changes and conflicting signals from overlapping surveys are
common challenges facing assessment expert groups. WGISDAA will
promote and review priority case studies that address these challenges.
