Hey I am 14 and thats simply how I started in this hobbie, with little crabs and fish from the beach. I once even found a fair sized Rock Cod trapped in a tide pool and it was covered in sea lice. I do this just about every summer and then when stuff starts going bad out into the ocean they go. By far one of my favorite fish would have to be the Plainfin Midshipman (they make sounds like a duck
) they dont eat anything but prawns though.
