Abstract
In order to reduce sea lion capture, sea lion exclusion devices (or SLEDs) were introduced into the fishery in 2000. Since 2004 they have been used on most tows. The use of SLEDs has reduced the number of sea lions seen by observers, and consequently the estimation problem has become more difficult. The performance of the estimators is compared under assumed levels of SLED coverage, ranging from 10% to 90%.
