It has been a busy winter for the Ontario Animal Health Network, with many completed research projects, seasonal reports, and new resources for vets.  We also held our annual general meeting on February 6, which allowed everyone to get together (virtually) to hear about the activities other networks have been working on.  The invited speaker was Dr. Zvonimir Poljak who presented his exciting work on the Animal Health Dashboard project.  To view any of our network reports and research projects, go to OAHN.ca and navigate to the species in which you are interested.

OAHN Aquatics Network Spotlight

The OAHN Aquatics network has recently published two resources relating to the mysterious death of arctic char at the Ontario Aquaculture Research Centre. The producer-focused article is available here: Solving the Mystery: A Guide to Identifying and Treating a Recent Disease in Arctic Char; the vet-focused case study is available here: Arctic Char Case Study.

Additionally, the OAHN Aquatics network has created courses for aquaculture producers and recreational fishers on humane harvest:
