My husband once caught a 3 foot sand shark at the NJ shore. We made 1 inch slices along the spine, and breaded and fried the pieces. I left a batch of the fried pieces in the refrigerator, and my little (7 and 10) sons would grab a piece whenever they were hungry and go back out to play. It was a tasty shark.
Rat fish are nothing like any variety of common shark
Shark, by the way is like deer meat, an incomplete protein - you need another protein source, like beans, to make a whole digestible protein - else the meal for nothing for you.
I’ve tried shark, mostly for the irony, enjoyed it.
