Here is some highlights from a newspaper article back in June 1936.
Fisherman in the Egegik district (Just south of Katmai) of the Alaska Peninsula are reported to have made good pay at catching Dolly Varden trout and turning these predatory fish in for the bounty during the past winter. Some made as much as $2,000 at the rate of 2 1/2 cents for each tail turned in. The results, it is believed, will mean an eventual increase in the red salmon run in this area.
$2000, that’s 80,000 char taken in one winter. What history has told us now is that many of the tails turned in were found to be from salmon, the species they were intending to protect. Also depleting trout and char populations in effort to increase salmon populations in actuality has a detrimental effect on the salmon.
