Aquatic Animal Health

The primary role of the AAHP is to provide outreach and training so these aquatic animal stakeholders can strive to maintain the highest quality of animal health, husbandry and welfare.

The Wet Pet Vet

Dr. Tim Miller-Morgan wiggles his fingers into surgical gloves. They snap against his wrists like rubber bands. On the operating table in front of him, a sedated patient lies on her back. She was diagnosed with a parasitic infection a week ago, so she has been undergoing treatments. Today, she’s in for a checkup.

Helping Aquarium Industry Maintain Fish Health

This video includes Project Piaba, an effort by AAH and Miller-Morgan to help ensure that wild fish imported from Brazil for the aquarium industry are healthy. As part of this work, Dr. Miller-Morgan travels to the Brazilian rainforest every year to train exporters and others to properly care for the fish. He's interviewed in this new documentary about the industry. Part 1 and Part 2 of this video is now available for free on YouTube.
