Inter-ship calibration is a comparison between integrator
output of two or more ships sailing over the same fish
aggregations. Although it is a relative measurement, it is
highly desireable whenever research vessels work together on
acoustic surveys. It is used to verify results of absolute
calibrations and may also elucidate possible ship effect on
abundance estimates.
An inter-ship calibration between two cooperative research
are presented and the results discussed with respect to difference in performance.
