Sea lice dropped after salmon farms removed

A new study published in the Canadian Journal of Fisheries and Aquatic Sciences examined juvenile pink and chum salmon at sites in the Discovery Islands, British Columbia, over the years 2020-22. The study's findings show a 96% decline in the average number of parasitic sea lice observed on juvenile salmon during this period. This coincides with the removal of salmon farms from the region during this period. Read more about it in a Business in Vancouver story.
