The reason I"m asking is, my father and I went out on friday(5-5-06)and tried dipping jigs around the docks but caught nothing until we gave up and started trolling 1/2 oz. rattle traps for stripers about 20" off the docks and instead of stripers, we ended up with 8 crappie, all over 2 lbs. Are these fish in a prespawn pattern, and if so what water temp. should Ilook for? Discovery Bay is in the West Delta regieon of the Bay Area.
