I’m curious about a few adult fish (male and female) being so successful in such a short span of time. If that is the case then why don’t the DNR just stock a few adults. .
It has to do with species and manageability. When you are dealing with non-native species - whether that be jack rabbits in australia or walleye in utah - there are no natural systems in place to control populations. Ask yourself a question: what type of habitat does a walleye require to successfully reproduce? They require rocky bottom water to about 20 feet in depth. Most Utah reservoirs provide this in ample amounts! Now, contrast that with what a native cutthroat trout requires: cold, clear, moving water with the right size substrate - and isn’t de-watered for irrigation shortly after eggs are laid! That’s something most of our Utah reservoirs don’t have! Further, the real risk: how do you control the population? If you provide good spawning habitat for walleye, how do you limit their success to keep their population in check? In Utah, the only way to do that is to draw the water level down below where the fish spawned leaving the eggs high and dry. Otherwise, you end up with the typicall boom / bust cycle that we are all too familiar with.
So, when asking why “a few adult fish being so successful…”, it all has to do with species and manageability.
Because when I go to Powell I’m going to fish for species that I can’t fish for where I live.
Deer Creek is just a few miles down to road from where I live and it is much easier to get my walleye fix there instead of a five hour road trip to Powell to catch what is right in my back yard.
and this ^^^^ is EXACTLY why we have problems with our fisheries. Everyone wants to have their own special fishery with the species of their choice in their own backyard. How do you satisfy every angler when this mentality is the norm?!
So, for those who wanted Echo to be a pike fishery, what should they do? And for those who want Echo to be a catfish fishery, what should they do? And for those who want a burbot fishery at Echo, what do they do?
It’s all selfish to the detriment of everyone.
If walleye were as great as many make them out to be, then people would quit fishing Powell for stripers and target walleye. But people don’t. They continue, even with walleye contests going on right now, to fish for stripers. Why is that? 2 tagged walleye since July. That’s with biologists stating specific locations of where tagged walleye were released. Who’s fishing for those walleye? Nobody.
