Fish Health

The GLFT’s primary interests are in priorities established by the Fish Health Committee of the Great Lakes Fishery Commission. In view of these priorities, this theme supports research that focuses on such issues as:

  • Diseases that affect the growth, survival, reproduction, or use of one or more Great Lakes fish species (e.g., factors influencing rates of infection and mortality, transmission mechanisms, disease ecology and epidemiology)
  • Nutritional aspects of fish health (e.g., role of lipids, issues related to thiamine and thiaminase-producing organisms)
  • Management and diseases (e.g., relationship between management practices and disease manifestation, effects of vaccinations, emergency response planning)
  • Efforts to build management capacity, or collaborative management capacity, related to any of the above (e.g., appropriate workshops and training, shared databases, common protocols)

The published research priorities of the Fish Health Committee will be updated in the future, and the GLFT will consult the most recent published list as it develops RFPs for fisheries research.


The GLFT has relatively greater interest in efforts that yield knowledge, protocols, or practices with application to demonstrated long-term issues of health and/or disease, or to issues of health and disease with relevance to numerous species. Conversely, the GLFT has relatively less interest in efforts limited to a single, specific pathogen or disease outbreak, particularly in circumstances where there is lack of consensus about the severity, persistence, or likelihood of impact of the pathogen or disease and where the timeline for management action is short.


The GLFT does not fund research related to the human health implications of environmental contaminants and Great Lakes fish consumption.
