Hi Mary,
Skate wings come from Skate!
a relitave of sharks, like sting rays...
Here's a picx of a skate... you only eat the "wings"...

I have always bought them fresh... I have never seen them frozen... or mostly caught them ourselves...
(Deb freaked when she caught her first one!)
The key is smell... if you ever find them in a supermarket or fish monger...
ask to smell them...
if you smell any scent of ammonia... DON'T BUY THEM!... they are OLD... they will taste like... well piss...
If they only have a "very slight" smell of ammonia, you can neutralize it with Lemon or Lime... (acid vs. alkaline)...
