At least 274,000 salmon were killed in the three breeding bases in Newfoundland and Labrador (NL) , and the mortality rate exceeded 10% of the total farming
.
It is said that the three affected farms, Little Bay (with a breeding capacity of 830,000 fish), Chaleur Bay (985,000 fish), and Friar Cove (929,000 fish), are located in the southern and western regions of NL, respectively.
The specific economic losses caused by salmon deaths are still there.

According to a statement from Mayway, “Farmed salmon on the east coast of Canada has been dying after receiving treatment for fish.
The increase in mortality did not occur in a single incident, but was discovered within a few weeks.
Most of the dead fish have been cleaned up in accordance with regulations

Roberts said that Maywell Canada has adopted the'thermolicer' technology to kill the fish.

Roberts said that usually in August, September, and October of each year, the sea temperature is higher, the dissolved oxygen drops, and the reproduction rate of fishes is also increasing, accompanied by algae problems

Dealing with fish disease also faces many environmental challenges.
Once fish are stressed, their demand for oxygen will increase

In September of this year, the number of salmon deaths at the NL farm in Mayway Canada continued to increase, from 100,000 at the beginning of the month to 485,000
.
These dead salmon weighed 3 kilograms and were originally planned to be caught before the end of the year
.
Meiwei said that at the end of summer, coastal aquaculture in NL faces environmental pressures, and the site conditions are the most tense and changeable.
The sudden drop in dissolved oxygen has become the main cause of salmon death
