dont know about yakkas and slimeys but the shallow banks @ boat passage often ends me up with a few poddys and some herring and sometimes a few gar and pike. hope this helps as i have usually got enough livies in these shallows to see me through a days flatty fishing. p.s. if you locate yakkas or slimeys give us a yell as sports fish currents are not that far away and it often pays to have them prior to heading out just incase they are not @ once out on the water.
