Cheap can of cat food from big lots seems to work pretty well. No freezing needed and in single use size

As a former assistant scuba instructor we used to use sea urchins as mentioned above by a couple of us and we also used to use frozen peas. We'd take the students down and have them kneel in a circle then tear open the bag of peas in the center of the circle and watch as it was swarmed by dozens and dozens of fish

Always a crowd pleasure on their last certifying dive

The peas would mostly bring in perch, bass, sheepshead and especially garibaldi

They didn't really bring in any bait fish we would want

But it always made for a great show

You are talking about Uni Butter, which is a fish attractant you smear onto artificial lures. This is Uni Goop. This is a chum product. Tommy Gomes makes both products.

I use ground cat and dog food. Works great.
