I wondered that.Does restocking by plane work?
How many fish survive being dumped from that height and at speed?
Both. Over a few summers many years ago I got to participate in a number of alpine lake surveys for the specific purpose of identifying lakes to stock and what type of stocking to use. We surveyed the perimeters of the lakes, checked the input and output flows of the creeks in an out, if present (a number of alpine lake don't have either). We also measured the dissolved O2, depths, and water temperatures. We did not take pH readings but all our surveys were in the front ranges of the rockies where limestone and limey shales predominated the bedrock. When stocking time came some of us also did post stocking assessments, hiking into the lakes before the drop then using a small inflatable to check for mortalities. In all honesty there are always some mortalities but the mortalities from the airdrops did not seem statistically more numerous than by the other method and the mortalities were due to physical damage either by the loading of the fish or the release. The drop doesn't appear to hurt them. I cannot find the original work I was involved with but here is a paper from a similar study done south of the border at a similar time. https://collaboration.idfg.idaho.go...s of,planted in the littoral zone of the lake.Releases from aircraft, or from land-based vehicles?

I guess it gives a new meaning to flying fish....
Temporarily, anyway....I guess it gives a new meaning to flying fish....
Maybe there was a group of big predatory fish sitting under the chopper eating them as they hit the water.I participated in a number of releases and don't remember seeing any fish floating to the top.
Yeah it happens from time to time, and not just here. It happens in the US and Indonesia too. Fish get picked up by cyclones (hurricanes) and dropped off wherever. It's not commonly seen but is on the news every 10 years or so.
There was a character on a British comedy program (Lee & Herring? - I forget) called Shadwell.
