If you give a man a fish, he'll eat for a day. But if you teach a man to fish, you'd better tell him what to do if he reels in a world record.

Robert Ross was fishing in remote waters near Loreto, Mexico, when he landed a record-breaking 430-pound yellowfin tuna, according to GrindTV.

Ross's catch might have broken the current world record for yellowfin tuna -- set in 2012 with a fish that weighed in at 427 pounds -- but he made one big mistake. 

When Ross called local fishing charter business Pisces Sportfishing to report his colossal catch, he had already filleted it. Pisces Sportfishing manager Tracy Ehrenberg reportedly told him, "You just cut up your world record."

Pisces Sportfishing did not immediately return a request for comment from The Huffington Post.

For a fish to be considered for a world record, it must be weighed intact on a scale that is certified by the International Game Fish Association.

Unfortunately, Ross was in a remote location when he landed his catch and didn't have access to a certified scale, Pisces Sportfishing explained on its Facebook page. That's why he went ahead and chopped it up before he made the call.

Prior to 2010, it was widely believed that fishermen would never see a yellowfin tuna weighing over 400 pounds. That changed when two massive yellowfins were caught in 2010 and 2012 -- at 405 pounds and 427 pounds, respectively -- proving there are, in fact, more fish in the sea. 

So don't worry, Ross, next time you reel in a big one, you'll know what to do.
