Farmed salmon in Norway at peril: 11,600 tonnes already killed due to algae bloom

 


Algae bloom in northern Norway is putting more farmed salmon at risk after killing some 11,600 tonnes of the fish, the Norwegian Directorate of Fisheries said, according to a Xinhua report.

 

The loss accumulating from the death of the 11,600 tonnes of farmed salmon in the northern counties of Nordland and Troms is estimated at 720 million kroner (US$82.04 million).

 

The directorate could not determine the total number of dead fish mainly because the breeders did not have the "capacity and overview to say the numbers" and the weight of the fish varied from 700 grammes to 5.5 kilogrammes.

 

As per the Xinhua report, the algae could stick to the gills of the fish and choke them, and while wild salmon can swim away from the algae, the farmed salmon in the offshore pens are trapped.

 

The directorate warned that the algae bloom in northern Norway was not yet over, thus posing as a risk to the other fishes.

 

Breeders have been on alert, the report said.
