The trout of thousands of salmon is flown into the lake by the aircraft

The aircraft was used to fish down many mountain lakes in Utah, USA, to serve fishermen.

This is the method used to supplement fish for many high mountain lakes in Utah, USA.

The Utah Wildlife Service (UDWR) shares a video that captures the sight of thousands of spotted salmon on the lake from an on-board tank, Sun reported on August 30. This is the method used to supplement fish for many high mountain lakes in Utah, USA.

"The fish are very small, only about 2.5-7.6 cm long. This helps more than 95% of fish survive the fall," said UDWR representative. This is the fastest and safest way to bring a large amount of fish into the lake, according to UDWR. This is to help those who come here to climb mountains to go fishing.

While many viewers were surprised and excited, some criticized this action for hurting the salmon and questioning the reason for not dropping fish from lower elevations or using the road."These lakes are very far apart and not near the road. Transporting fish by road will take days and it is difficult to maintain stable oxygen levels," explained UDWR representative.
