Salmon trapped in Canada landslide to be airlifted to safety
https://www.bbc.com/news/world-us-canada-49066718Salmon trapped in Canada landslide to be airlifted to safety
22 July 2019
Thousands of Canadian salmon are going to be airlifted to safety after getting trapped by a landslide. In June, officials found the rocks had blocked off a section of Fraser River in British Columbia, s topping the salmon from swimming upstream to spawn.
Rescuers have spent weeks devising a plan to fly the fish by helicopter to a spot on the other side of the rockfall.
Conservationists warn the fish need to be able to lay their eggs, or the local salmon population will be at risk.

Crews are now constructing a holding pond for the salmon. The fish will then be transferred from the pond into 780-2,700 litre tanks, before a helicopter moves them away from the landslide. The water in the tanks will be oxygenated, to help keep the fish calm.
