Decision variables:

Variable:Recommendation for consumption of farmed salmon | Variable:Pollutant concentration limits for fish feed

Indicators:

Variable:Pollutant health risk due to the consumption of salmon | Variable:Net health effects due to the consumption of salmon

Other variables:

Variable:Persistent pollutant concentrations in fish feed | Variable:Persistent pollutant concentrations in salmon | Variable:Salmon intake in the population of the Western Europe | Variable:Exposure to persistent pollutants due to salmon in the population of the Western Europe | Variable:Dose-response function of persistent pollutants | Variable:Omega-3 content in salmon | Variable:Omega-3 intake due to salmon in the population of the Western Europe | Variable:Dose-response function of cardiovascular effects of omega-3 fatty acids | Variable:Total mortality in the Western Europe | Variable:Cardiovascular mortality in the Western Europe | Variable:Cardiovascular effects of omega-3 in salmon in the Western Europe

Scope

Pollutant concentration limits for fish feed describes a decision whether a stricter limits should be set for pollutants in fish feed or not.

Definition

Data

The motivation comes from the observation that the consumption recommendations actually do not bring health benefits. Therefore, the risks of pollutants in fish should be regulated another way. One possibility is to regulate the pollutant concentrations in fish feed, as they correlate well with the final concentrations in the fish meal. Two options are assumed for fish feed regulations: 1) business as usual (BAU) with current legislation, and 2) More restrictive regulations for fish feed, resulting in reduction of pollutant levels in feed and consequently in salmon. (This is irrespective of any trends unrelated to the decision).
