Neil Frazer L, Morton A, Krkosek M
Proc Biol Sci . 2012 Jan; 279(1735):1950-8. PMID: 22217721
Host density thresholds are a fundamental component of the population dynamics of pathogens, but empirical evidence and estimates are lacking. We studied host density thresholds in the dynamics of ectoparasitic...

Krkosek M, Connors B, Morton A, Lewis M, Dill L, Hilborn R
Proc Natl Acad Sci U S A . 2011 Aug; 108(35):14700-4. PMID: 21873246
The ecological risks of salmon aquaculture have motivated changes to management and policy designed to protect wild salmon populations and habitats in several countries. In Canada, much attention has focused...

Krkosek M, Connors B, Ford H, Peacock S, Mages P, Ford J, et al.
Ecol Appl . 2011 Jun; 21(3):897-914. PMID: 21639053
For some salmon populations, the individual and population effects of sea lice (Lepeophtheirus salmonis) transmission from sea cage salmon farms is probably mediated by predation, which is a primary natural...

Krkosek M, Morton A, Volpe J, Lewis M
Proc Biol Sci . 2009 May; 276(1668):2819-28. PMID: 19419983
The ecological impact of parasite transmission from fish farms is probably mediated by the migration of wild fishes, which determines the period of exposure to parasites. For Pacific salmon and...

Krkosek M, Ford J, Morton A, Lele S, Myers R, Lewis M
Science . 2007 Dec; 318(5857):1772-5. PMID: 18079401
Rather than benefiting wild fish, industrial aquaculture may contribute to declines in ocean fisheries and ecosystems. Farm salmon are commonly infected with salmon lice (Lepeophtheirus salmonis), which are native ectoparasitic...

Krkosek M, Lewis M, Morton A, Neil Frazer L, Volpe J
Proc Natl Acad Sci U S A . 2006 Oct; 103(42):15506-10. PMID: 17021017
The continuing decline of ocean fisheries and rise of global fish consumption has driven aquaculture growth by 10% annually over the last decade. The association of fish farms with disease...
