Agriculture and Environment: Salmon
Environmental Impacts of Production: Mort Disposal
Approximately 20% of salmon die during grow-out, some of them from diseases that could potentially be spread fro the improper disposal of morts.
A variety of disposal methods is used; the principal ones are landfilling, composting, and ensilage (a liquification of the morts that is then used in animal feed or fertiliser).
Some companies dump morts into the ocean, where the chemicals ingested by the salmon before death, as well as any diseases that may be present, are released into the environment.
