The environment has nothing to do with any of this,, there is nothing wrong with the environment regarding Steelhead survival or production... its likely slightly out of balance for the purpose of gaining control over it but not damaged or broken in any significant way...

The reason why there are not more steelhead is because of purposeful over harvest which continues in the terminal areas/feeding grounds on an already decimated stock that was over harvested even more in the past so that control over abundance could be gained...

The Indians did not do it initially,, they lived for thousands of years by the rule of subsistence,, "take only what you need",, it was a successful management model... Now the Indians are on the take/government/bank payroll so they are used as a tool of "management",, getting abundance under control by targeting stocks in terminal areas to manage the abundance into manufactured scarcity... The Indians are being used via giving them Greed for wealth and the unfair advantage of overharvest opportunity...
