Presentation Synopsis:
The study of gill disease in marine salmon aquaculture has focused mostly on AGD primarily because it has been the easiest to culture and develop challenge models for. In reality there are numerous agents that can also affect gill disease, and not all of them may interact to give rise to a complex gill disease syndrome which is becoming more widely recognized. Although treatments focus on amoebic gill disease and are often effective at treating amoebae, the other agents seem largely unaffected and gill health management remains the only and limited tool for addressing these problems.
Presentation Learning Objectives:
- 1. What is AGD pathology and pathophysiology?
- 2. What multiple agents are commonly associated with complex gill disease syndrome?
- 3. Treatment and control options for gill disease in marine salmonid aquaculture.
Speaker Bio:
Dr. Powell has worked with aquaculture health and production biology specialising in gill health of fishes for the past 25 years. His focus on treatments and operational approaches to managing amoebic gill disease in sea cages has been applied across the industry. He has extensive experience with Recirculating Aquaculture Systems technology and the role gill health plays in fish production.
