LOL...I know everytime I see fish jump it gets me excited too! The fish you saw are most likely mullet...Very hard to catch!
When mullet have been feeding like this, I've often been amused at the attempts of frustrated anglers, trying to hook one of these fish. Casting all types of baits toward them, bread, worms, flies, spinners, and sometimes finally resorting to large bare trebles, in a desperate attempt to foul hook one out of frustration.
Good luck chasing them but don't expect any hook ups!
