Marine Harvest Atlantic Canada is reporting that higher than normal mortalities were observed among lumpfish being transported to a site called Steamers Head off the southern coast of Newfoundland on Tuesday.
“These were non-disease related mortalities that occurred at site during the transfer of the lumpfish. The abnormal mortalities were the result of rough sea conditions at the site immediately post transfer,” the company said in a news release.
“Two other sites were supplied with lumpfish during the same supply trip without issue.”
The company said approximately 12,300 lumpfish deaths occurred, which is about 19 per cent of the total 65,700 lumpfish transferred to the site.
Lumpfish are used by fish farm companies to eat sea lice off of farmed Atlantic salmon.

The company said removal and disposal of all dead fish is conducted “per standard operating procedures.”
“Marine Harvest Atlantic Canada has taken all responsible steps under the oversight of the Government of Newfoundland and Labrador’s Department of Fisheries and Land Resources, and is following government policies in this matter.”
