Everybody needs vitamin d, which can be found in foods like sockeye salmon, eggs, and milk.
Two groups of sockeye that spawn in lakes near Vancouver are also listed as endangered.
Many migrating Fraser sockeye (both outbound as young smolts and inbound as mature fish) pass some two-dozen salmon farms in the Broughton Archipelago.
Studies by local and Norwegian scientists have found that sea lice and other parasites from the fish farms can infect the passing sockeye, reducing their chance of survival.
