I Suppose I can understand the Tiger Hate. They are hard to catch when you want to, tear up tackle when you are not fishing for them.
On occasion, they may eat a precious trout, especially if it is injured and on the end of your line, or stringer.
They look scary.
They are new.
It is true that Newman and Silver don't get trout plants, in part due to the number of competing warm water species. Still, in most lakes, the trout do fine with Tigers, and I expect that when the rough fish are thinned down the trout may be planted again in Silver and Newman.
In Silver, the perch are larger then in many many years, and growing, mostly due to the Tigers. In Newman, the Bass, Crappie, and Perch are all starting to get larger, and the Carp fewer.
What so many people do not understand it the bio-mass concept of fisheries biology. You can have only so many pounds of fish in a lake. You can have a few very large fish, a lot of very small fish, a moderate amount of moderate sized fish, or, if you are lucky, a good distribution of sizes. No where does this model discriminate against species? And the overall poundage or bio-mass of a fisheries depends on how fertile the water system is.
With that in mind, do you want your alloted "poundage" in rough fish or game fish? If you want your poundage in game fish, which ones, stunted Bass and Perch or a few large Tigers and a distribution of Bass and Perch sizes.
Rainbow trout (Bow River California is there home) are no more native to our waters then are Bass. Sure, in some waters, there was Steelhead (no migrating Steelhead are now considered Rainbows), but these were in rivers and streams, not lakes. You had Red Bands that look like Rainbows, but they too are river or stream fish, not lakes. You had some West Slope Cutts, but again............ Getting old.
So, what did we have? Squawfish (or is that Northern Pikeminnows?), suckers, sculpin, and that is it for our Lakes. The exception was the Lakes that had rivers with unobstructed access to the ocean, and they had transient populations of the ocean running fish.
So, the question is, how do we educate fishermen? Time, effort, teach the young, and realize that some are just too old, too dump, and too stubborn to learn.
