We're on the same page. Lake trout are certainly considered a predator, and we know they eat plenty of alewife. If you read any of the lake trout rehabilitation documents, they specifically state that one of the impediments to lake trout rehabilitation is that they eat alewife, which inhibits reproduction (thiamine deficiency syndrome). Hence, why I stated that building up alewife is in direct conflict with lake trout restoration. To what degree it conflicts is up for debate depending on who you ask.
However, lake trout have the most diverse in diet of all the salmonids, and are very opportunistic. They are probably the best link right now between the lower end of the food chain and the predators - the quagga mussels siphon energy out of the water column, the gobies eat the mussels, and the lakers are the biggest consumers of gobies. So that is a positive.
We realize lake trout are far less desired by sport anglers, we only hear it about 365 days of the year. By phone, in person, at meetings. And we see it on forums. And so forth.
The reason we cut chinooks first is for a few reasons. 1) because the states have full control over silver fish, whereas lake trout are more complicated: there is the 2020 consent decree with tribes, which mandates by law a certain level of lake trout stocking in some areas, and because the USFWS stocks 99% of lake trout, so states do not have direct control. We (the states) had a pre-set agreement amongst ourselves regarding salmon, which made implementation of stocking reductions much easier, compared to wrangling with feds and tribes over lake trout for potentially years, all while alewives continued to decline precipitously.
2) because of how few alewives, and just as alarmingly, how few yearclasses of alewives were out there, we wanted to pull the emergency brake on alewife consumption, to reduce predation pressure as quickly as possible, and give them a chance to pull off some spawns and survive to older ages to spawn again (btw it looks like that is starting to work). Given how quickly chinooks grow and how much alewife they consume, cutting them was the fastest and easiest way to avoid crashing the alewife populations like happened in Lake Huron. For example, cutting lake trout stocking today would not really have much of an effect for 3-5 years, because they are slow growing. A chinook can grow to 20+ pounds in the same amount of time that it takes a lake trout to grow to 5 pounds.
Having said all that, the time is now to start talking about lake trout reduction. The Lake Michigan Committee already got that ball rolling last year, and asked the USFWS for the elimination of 500,000 fall fingerling lake trout. It's not a big dent in the numbers, but it was a start. I expect more serious conversations about lake trout stocking reductions to take place this summer at a lakewide meeting of scientists and managers.
Another option to consider is increasing the bag limit from 2 to 3 - not sure how popular that would be or how many anglers would take advantage of that. Thoughts?
