Introduction to spread of aquatic diseases Pathways to spread of diseases (Peeler,
2011) Data from Fuentetaja’s article from 2006
about botulism outbreaks in Lake Erie. Conclusion of botulism outbreaks Possible solutions
Diseases can be spread through◦ Movement of fish, birds, and invertebrates
changing their location◦ Movement of aquatic organisms from one area to
another by humans◦ Destruction of habitats due to land alterations by
humans (stress on organisms)◦ Creation of habitats for organisms that carry
parasites, diseases, and vectors by humans
Lake Erie has increasingly often occurrences of anoxia
Settling of organic matter when nutrients run out during late summer
Both create an environment for C. botulinum growth
Toxin spreads from invertebrates to fish to birds and cause mass deaths
Lessen human impact on lake and river quality (ex: attempt to decrease nutrient loading)
Monitor movement of aquaculture organisms
Set fines for release of aquatic organisms (accidental or not)
