Ever seen a "shrimp farm" in Hawaii? 
Tilapia are raised the same way...I don't eat 'em.
Like I said "septic tank raised"
We used to cast net for table shrimp when we lived in NE Florida. Once
you get the hang of tossing a cast net, it's pretty simple.
We used a long handle dip net and walked along the sea walls with a
flashlight. Look for the red eyes.
My place in Treasure Island (St Pete) was great for it. There was
about a half a mile of seawall and back when the Boca Ciega bay was in
good shape you could usually get dozens of shrimp in an hour or two.
It is really a 2 person job, one with the net, one with the light.
