I would favor a larger slot, say 24 inch, barbless, single hook, no bait, for Strawberry. That’s probably not based in good science, just my opinion. That’s the other extreme. The compromise is what we have, and it is working.
Does anyone remember, after the last poisoning, and before the put the slots in place, what the average size of cuts was?
My first exposure to Strawberry was in 1961. Just after I arrived in Utah, in September I believe, Strawberry was poisoned for the first time. It was still a separate lake from Soldier Creek and was overrun with non-trout species…chubs, perch, carp, etc. I was told that it was difficult to catch a trout because of all the other competition.
A couple of newfound friends drove me up to help “harvest” the fish floating to the surface after the rotenone treatment. No harm to humans from eating them. The surface was covered with fish and few of them were trout of any size. A very few bigguns but mostly small “trash fish”.
When Strawberry was restocked with mostly rainbows and some cutts the fishing took off quickly and the fish grew fast…without the chubs to compete for available food resources. But that was mostly rainbows.
**Over the years the chubs found their way back into the system. Hard to ever kill all of them because some always survive in the tributaries. By the mid 70’s the ratio of chubs to trout caught was increasing. **
After the two lakes (Strawberry and Soldier Creek) were joined and the lake poisoned for the last time there was again a resurgence of trout action. And everybody was able to take home coolers full of bows and cuts. But it didn’t take long for the chubs to start multiplying again…along with redside shiners. By then it was far to expensive to consider a major poisoning program again so the cutts and slot program was put in place.
**I attended a slide presentation put on by Alan Ward, one of the DWR folks in charge of the new Strawberry. He posted some interesting stats on how the slot program was working…only a couple of years after implementation. One of the chart comparisons was related to the sizes of the fish captured during netting surveys. Prior to the slot program the average trout was in the 12 to 13 inch range…with very few exceeding 20 inches. After the slot program became operational the average jumped up to about 18", with many fish over 20 inches and a substantial number over 24". **
Sure, I remember some larger fish coming out of the Berry before the slot…but they were rare. In the past few years we have seen many anglers smiling over cutts in excess of 26 inches…and many more bows in the higher poundages too.
**Along with the size changes in the trout there was monitoring of the stomach contents and in the biomass of the chubs and shiners. It was proven that the larger cutts were switching to a minnow diet somewhere about 18" and that they had already made serious impacts on the shiners and were holding the chubs in check. **
In short. Overall conditions for fish and anglers are much better now. The numbers prove it. Big fish get big in two ways…lots of food and restricted harvest. But it doesn’t matter how much they have to eat if they are all removed before they can get big enough to eat the chubs…and grow bigger.
