Salmon and trout producer Cermaq has released its quarterly sustainability results on key indicators related to fish health for the first quarter of 2018.
The company said the key takeaway on sustainability performance from the quarter includes survival rates spanning from 92.5 - 97.3 percent on a 12 month rolling basis, with the highest level achieved for trout in Chile.
In fish health performance, use of antibiotics in Q1 was reduced by 70 percent in Chile compared to the same quarter last year. In Canada, the use was “further reduced” to 9 grams of antibiotics per tonne of salmon harvested within the quarter. The fish harvested by Cermaq Norway in the quarter did not receive any antibiotics, it added.
Average sea lice levels at Cermaq sites worldwide were within regulatory limits, “with the exception of a few sites in Canada where the levels exceeded the regulatory limit and have continued doing so,” said the company. It added that the situation “is being addressed by all available means, including early harvesting and by treatment with hydrogen peroxide.”
Cermaq also reported one incident of escapes in Chile, where 6,284 fish, weighing 2.9 kg each on average, escaped its operations due to ripped nets.
The company started publishing quarterly sustainability results in early 2016.
