This five-day course offered by VIU’s Natural Resources Extension Program focuses on the key principles of fish health management for aquaculture (hatcheries and net pen) and aquarium fishes. The theoretical components emphasize recognition of what is ‘non-normal’ in fish husbandry settings, along with covering types of diseases (i.e., environmental, pathogenic, parasitic or genetic), prevention and mitigation, and proper techniques for fish sampling and biosecurity.
