Response of cohort analysis to change in proportion of catch reported / David F. Gray. : Fs70-8/78-15E-PDF
"This short note investigates the effect on a cohort analysis of a change in the proportion of a catch that is reported. To do this, data was generated using the catch equation, a particular set of partial recruitments, a fixed M and randomized recruitment and fishing mortality.The catches were then adjusted to simulate an under-reported catch for several years followed by a varying number of years of fully reported catch. These new figures were then analyzed and compared to the originals to determine first, how fast cohort analysis adjusts and second, what, if anything showed that a change in reporting had taken place"--Introduction, page [1].
