design. If fish abundance in this area is higher in late July at the end of the 2 month survey period, benefits gained on the northern border of the survey area might be lost if the survey is changed so that it proceeds from the northwest to the southeast. In any case, benefits expected from a change must be weighed against potential disruption of the time series Improvements in the methods used to locate trawl hauls and pool them objectively might result in greater efficiency and an associated reduction in the number of trawls needed to scale echo integration data. This could reduce the time needed for a survey. Reductions in the time needed for a survey should also improve precision, as problems with movements of fish into and out of the area would be reduced. Modifications to Protocols Changes to operational protocols will be at the discretion of the AFSC Science Director who may approve such changes directly or specify a peer review process to further evaluate the justification and impacts of the proposed changes.
