Hey I dont know the legality of it there but you can get a bait net and go out and catch your own natives. Here it is legal with a few stipulations. Its free plus its really rewarding. You can also look up fingerling suppliers/fish stocking companies near you. The ones here have some pretty remarkable variety. Good luck bro!
CA has some of the most strict laws in the country when it comes to collecting; it's basically illegal to take a fish from any body of water (alive). I don't know about buying from a farm though...not sure how that would work.
Thats nuts man. Even for the non-game fish you guys cant collect? Any idea of what you are looking for species wise? Sorry once again wtf? That is a crazy law.
