I was in San Diego Bay (back bay to be specific) and a friend caught this fish.. I cant remember what he told me it was.. it does not look like the spotted bay bass we were catching..
I bet that fish started to bleed for no reason. haha
That is a Pacific Mackerel. Those will generally school up and can be caught anywhere from 2 feet below the surface up to 100 feet at times when they are active.
I usually save quite a few of those for Crabbing and Lobster season. They also make good bait for Ling Cod, Whitefish and can be chunked to use for Shark bait at night.
