It sounds similar to here... Must have a licence to fish, and you cannot transport live fish, because their concerned about people moving fish/plants from lake to lake, and rightfully so. Except that here, you ARE allowed to collect as long as its for personal use in an aquarium (im not sure the rule on plants...)
Ive had tons of local fish spp. and I even posted the pictures in the fish section of the TPT site for most of the sunfish spp and a few hybrids. They destroyed my plants and I got rid of them eventually, so beware... I get to see alot of nice specimens at my job, too bad I dont keep them anymore!
