I have been catching a lot of small fish with my cast net that I have not been able to identify. The fish range from a half inch to an inch. The fish has a hard shell body and instead of having dorsal, pelvic and anal fins, the fish has two needle-like spines on top and on its sides.

I was wondering if anyone knows what kind of fish this is. Could the fish be an invasive species of some sort?

Im guessing a stickleback fish? google the name and look at the pics...

when i worked briefly at the benicia water treatment plant aeons ago, we used fish as birds in a cage to test the water. they were stickleback fish

Sticklebacks can tolerate brackish water. I just never heard of any living in the bay. That's pretty cool you caught some because a lot of stickleback populations aren't doing that well.

I used to catch sticklebacks when I was a kid in Stow Lake in Golden Gate Park. Just used a dip net and sat still and they used to swim right in.

Maybe the recent tides could have pulled some down out of the delta? Here's a clear pic & info on them.
