I don’t know how slow that airplane can get and still fly without danger of hitting a mountain, but those fish look like they were released at Mach 1 and darned high.
My guess is the mortality rate is much higher than they claim in the video…
The Gulkana Hatchery up in interior Alaska stocks Crosswinds Lake with millions of sockeye fry every year. The pilot drops them from about 100' up at about 150mph out of a modified crop duster. When I was involved he was using the yellow plane, apparently his new one has about 250 more hp and can go faster..... The survival rates of the fry are well over 90% believe it or not. They tried dropped them closer to the water and most of them died. Dropping them from further up gives them a chance to get oriented correctly. Trust me it works.
