We're about six months from mullet, but as soon as the fingers show up feeding in the back I'll have them in the tanks. It's awful hard to keep big bunker, but I'll have Peanuts as soon as they are big enough to stay alive on a hook.
The HERRING should show any day and I'll have them alive. And as soon as the SPOT show they will be here too.
I don't know where your fishing, but I'm easily accessable from the Atlantic County area and I have everything you need to keep them allive.
