Summary of information relating to impacts of sea lice from fish farms on Scottish sea trout and salmon
ثبت نشده
چکیده
Sea lice infest both farmed and wild salmonids to the potential detriment of aquaculture and angling interests. Several reviews have recently considered information concerning interactions between salmon farms and wild salmonids (e.g. Revie et al. 2009; Costello 2009; Whelan, 2010). Here, the evidence available to assess the likelihood and scale of impact of sea lice from salmon farms on Scottish wild salmonids is summarised. The aim is not to repeat extensive review but to focus on key issues relevant to locating fish farms in the Scottish coastal zone.

Temporal and spatial patterns of sea lice levels on sea trout in western Scotland in relation to fish farm production cycles.
The relationship between aquaculture and infestations of sea lice on wild sea trout (Salmo trutta) populations is controversial. Although some authors have concluded that there is a link between aquaculture and lice burdens on wild fish, others have questioned this interpretation. Lice levels have been shown to be generally higher on Atlantic salmon farms during the second years of two-year pro...
متن کاملThe use of prevalence as a measure of lice burden: a case study of Lepeophtheirus salmonis on Scottish Atlantic salmon, Salmo salar L., farms.
This study investigates the benefits of using prevalence as a summary measure of sea lice infestation on farmed Atlantic salmon, Salmo salar L. Aspects such as sampling effort, the relationship between abundance and prevalence arising from the negative binomial distribution, and how this relationship can be used to indicate the degree of aggregation of lice on a site at a given time point are d...
متن کاملSea Louse Infection of Juvenile Sockeye Salmon in Relation to Marine Salmon Farms on Canada's West Coast
BACKGROUND Pathogens are growing threats to wildlife. The rapid growth of marine salmon farms over the past two decades has increased host abundance for pathogenic sea lice in coastal waters, and wild juvenile salmon swimming past farms are frequently infected with lice. Here we report the first investigation of the potential role of salmon farms in transmitting sea lice to juvenile sockeye sal...
متن کاملSalmon-farming impacts on wild salmon.
C oncerns have been raised about the impact of farmed fish on wild fish through a range of mechanisms including disease and the impact of fish that escape from farms (1). Although Alaska has banned salmon farming and Washington has developed only a very small industry, British Columbia, with an extensive network of protected inlets, has developed a very large salmon-farming industry, now consid...
