>>1520456here in Germany catch and release is actually illegal and you could get your fishing license revoked for doing so.
there is special list with size and time for every river
if your fish is to small or it has breeding season you must put it back, but if its big enough you must remove it.
German law says its illegal to cause any damage or pain to animals for fun so catch and release is illegal.
Fishing is for Food and not for the sake of getting the biggest fish and taking photograph and bragging.
