World aquaculture is increasingly diversified and intensive, due to the use of new technologies, having grown a lot in recent decades contributed significantly improving food security reducing poverty world, with fish farming being promising activity for production protein high nutritional value. The large companies that recognize potential this important modality have invested study various pr...

Although increased disease severity driven by intensive farming practices is problematic in food production, the role of evolutionary change in disease is not well understood in these environments. Experiments on parasite evolution are traditionally conducted using laboratory models, often unrelated to economically important systems. We compared how the virulence, growth and competitive ability...

The salmon farming production chain is structured in four consecutive phases: freshwater, seawater, plant processing, and distribution and marketing. The phases interact in a pull manner, freshwater stocks fish to meet seawater’s demand, seawater produces to meet plant processing biomass demand, and the processing plant produces to satisfy consumers’ demand. Freshwater planning decisions are in...

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...
