Yes they will prevail but now that the large fish are shown to be at an all time high body to weight ratio on his graph without any stocked fish they will surely lose weight over time.
Quote from Ewert.
A couple messages that I get on a regular basis from the lake trout angling community are an almost universal lack of support for kokanee in Colorado
, and and the assertion that we can have perfectly good trophy lake trout fisheries based on a sucker prey base alone. These two positions are totally misguided - and quite possibly tragic for the future of trophy lakers in this state - but we've seen over and over again that it doesn't matter how many times we try to communicate this. Here is our golden opportunity to test these theories.
At least this time he is letting us know about the test rather than doing it at Granby with 3 years of Rainbow shortages without anyone knowing, then blaming it all on budget cuts when I discovered what was going on.
Whats misguided is this whole experiment along with the assumption that there is almost universal anti support among Lake trout Anglers for Kokanee.
As an avid Lake Trout and Kokanee angler I spent a huge amount of time, effort and equipment trying to maintain Kokanee in the state. At times more than the managers themselves.
When the Kokanee crashed at Lake Granby in 99 and we were losing our Kokanee egg supplies the Dow was taking aim at the Lake Trout. It took huge effort to convince the biologists to start taking eggs from Williams Fork and other smaller Reservoirs.
Yes Large Lake Trout will survive without Kokanee or Rainbows as Fordo says they will as they already do eat Suckers and smaller Lakers but they will Not do as well as they would with the added benefits of Kokanee and Rainbows.
Without stocked fish the Large Lakers will forage even more on smaller Lakers reducing there populations. We may see a small downturn of smaller lakers at Green mtn due to this but due to the 8 fish open limit without any protection on larger fish there I doubt there are enough large lakers to make much of a difference.
Of course the large Lakers at Granby have a general lower weight to length ratio as other areas, Granby is not a productive Reservoir and Green mtn is.
Not stocking any Rainbows at Green mtn. due to Pike and Gill lice will only be detrimental to the many Anglers that fish there.
