leervis in the cape area, can only think that you guys would vcatch them summer time. not up to date with the fish in your region. leervis move up north during winter time to durban and up to st lucia.
Zandvlei is a good place to start, then on occasion some are caught in the surf using poppers and big rapalas. Then another good place during summer is to the left of the wooden jetty in the strand spinning for them off the concrete blocks
