Caught jew with salmon baits before so no problems there.
I slab bait a fillet. I cut it into 3 or 4 pieces depending on the size of the salmon.
Any fish that is fresh will work off the beach, dont let people tell you otherwise.
Jew can be caught on trevally, dart, whiting, blackfish, sand crabs and tailor just to name a few. Basically if it swims around the beaches or beach headlands its good for bait as long as its fresh.
Now, Jew certainly have their preferences but if i had any of the above species as freshly caught bait (that is, i caught it that afternoon on the beach and will stay on fora jew session) i certainly would not be packing up and would be giving it a shot!
