Salmon lice – impact on wild salmonids and salmon aquaculture
Salmon lice, Lepeophtheirus salmonis, are naturally occurring parasites of salmon in sea water. Intensive salmon farming provides better conditions for parasite growth and transmission compared with natural conditions, creating problems for both the salmon farming industry and, under certain conditions, wild salmonids. Salmon lice originating from farms negatively impact wild stocks of salmonid...
متن کاملPopulation dynamics of salmon lice Lepeophtheirus salmonis on Atlantic salmon and sea trout
The salmon louse Lepeophtheirus salmonis is a common ectoparasite of both farmed and wild salmonids in the marine environment, and can have a significant negative effect on the survival and growth of its host. To facilitate development of models of salmon lice population dynamics, we review the available experimental information on its demographic rates and highlight areas where further researc...
متن کاملEffects of host migration, diversity and aquaculture on sea lice threats to Pacific salmon populations.
Animal migrations can affect disease dynamics. One consequence of migration common to marine fish and invertebrates is migratory allopatry-a period of spatial separation between adult and juvenile hosts, which is caused by host migration and which prevents parasite transmission from adult to juvenile hosts. We studied this characteristic for sea lice (Lepeophtheirus salmonis and Caligus clemens...
متن کاملRelationship of farm salmon, sea lice, and wild salmon populations.
Increased farm salmon production has heightened concerns about the association between disease on farm and wild fish. The controversy is particularly evident in the Broughton Archipelago of Western Canada, where a high prevalence of sea lice (ectoparasitic copepods) was first reported on juvenile wild pink salmon (Oncorhynchus gorbuscha) in 2001. Exposure to sea lice from farmed Atlantic salmon...
متن کاملAQUACULTURE: A Second Look at Sea Lice
global estimate of ShS Burden Call it what you will—passive smoking, environmental tobacco smoke, or secondhand smoke (SHS)—worldwide, exposure to the emissions from smokers’ cigarettes caused the premature death of an estimated 603,000 people in 2004, according to a team of academic and World Health Organization (WHO) researchers. This first global assessment of the burden of SHS was led by Ma...
