IF MY FISH IS 6 YRS OLD WOULD IT BE 19 INCH OR 33 INCHES OR COULD IT BE 13 YRS OLD ? THE ONLY WAY TO FIND OUT IS CHECK ITS SWIMING LICENSE. OR JUST ASK THE FISH IN PERSON , AND IF THE FISH WONT TELL YOU ARREST HIM OR HER.
Bobbythanks for the info. Now another question I understand the biologist can tell the age of a rainbow by the scales (at least I have heard that) but how can US as anglers tell, is there a fin clip for them and if not how can we tell?
