The purchase of this power plant will aid the Division of Wildlife Resources in keeping a disease-free operation at the Fountain Green Fish Hatchery by switching from an open-reservoir water source to a covered and piped-at-the-source system.
Many fish lose weight during the winter months and when ice off occurs, they’re hungry and eager to put the lost weight back on. What this means for anglers is that during ice off, fish are hungry, active, concentrated and willing to take almost anything you throw.
Last spring, annual netting revealed an 89 percent increase in the number of lake trout that measured less than 25 inches. Biologists also aged over a hundred lake trout of varying sizes, and it was immediately clear that they are growing much slower than they did back in the 1980s and 90s.
Many DWR biologists (including me!) started off as university students working on projects funded by the DWR, and that led them to a career with the agency. It’s a great path if you are truly serious about becoming a professional biologist.
The precautions and steps listed above, while helping to prevent the spread of invasive mussels, will also minimize waiting times for boaters ready to launch or exit the area, reduce confusion regarding both Utah and Wyoming AIS laws and aid boaters in complying with those laws.
The growing number of pelicans caught the attention of managers and anglers. “They’re eating all the trout,” was the concern. In response, we teamed up with and Utah State University and began tracking the eating habits of the birds.
Jessen and Tamarack lakes have numerous tiger trout larger than our 18-inch measuring board, yet these fish have two or three summers of lifespan left! The fat content on these fish is outstanding. These fish are flat-out impressive!
Wipers were introduced to Newcastle Reservoir in 2005, and by 2009 golden shiners had almost completely disappeared. Rainbow trout and smallmouth bass immediately started showing improvements and now they provide outstanding fishing opportunities.
We then place the eggs into a specially designed sieve that goes into a hydraulic pressure chamber. This chamber subjects the eggs to 9,500 PSI of pressure for ten minutes. This pressurization step is what makes the fish sterile.
As a biologist and angler who spends a lot of time on the reservoir, I have received reports and witnessed kokanee mortalities on the surface of the reservoir during the summer months. Sometimes there are so many dead fish, they look like bread crumbs trailing behind trolling boats.
The over-arching goal of the research is to restore native fish species, including Bonneville cutthroat trout, to fire-affected streams in the Tushar Mountains. However, the watersheds of these remote 12,000+ foot peaks do not provide data easily.
Keeping the fish you catch — up to your legal limit — is the key to providing fish with the food they need to grow. So keep your catch and cook it up for the fam!
