Mullet conservation efforts are under way in Pittsburgh — the hairstyle, not the fish.

The Pittsburgh Zoo and PPG Aquarium gave reduced admission Monday to those sporting the business-in-front, party-in-back look.

The tongue-in-cheek promotion kicked off a week of discount gimmicks at the zoo.

Stuck in the ’60s? A tie-dye shirt will get you in the gates for $5 on Thursday. On Friday, the zoo’s Facebook friends can get the lower price.

On Monday, the person with the best mullet won a behind-the-scenes zoo tour.

And the prize for the runners-up? A chance for a free haircut.
