Provo — As a part of an ongoing research launched two years in the past, the Utah Division of Wildlife Sources continues to be asking anglers to report and launch any tagged northern pike they catch in Utah Lake. And, as a result of the invasive fish had been positioned in Utah Lake illegally, anglers should kill any northern pike they catch that do not have a tag.
DWR biologists began tagging among the northern pike in Utah Lake and its tributaries in February 2020 as a part of a research to be taught extra in regards to the seasonal areas and actions of juvenile and grownup pike in Utah Lake, the Provo River, Hobble Creek and the Spanish Fork River. The research is anticipated to run for at the very least 5 years (till 2025).
Since northern pike sometimes spawn when the ice begins to soften, anglers could catch extra of the invasive fish at Utah Lake this time of yr.
The tagged northern pike have skinny, purple items of plastic hooked up to them. Tagged fish have been implanted with transmitters so biologists can observe them utilizing GPS expertise. Surgical scars must be seen on their underside within the unlikely occasion that the exterior tag is dislodged.
“We’re asking anglers to launch pike which have these tags as a result of the transmitters which can be within the fish allow us to trace their actions,” DWR Central Area Native Aquatics Biologist Keith Lawrence mentioned. “Monitoring their actions will assist us develop a monitoring and management program for northern pike sooner or later, which is able to assist threatened June suckers.”
Should you catch a tagged northern pike in Utah Lake or one in every of its tributaries, you must do the next:
- Name DWR native fish biologist Dale Fonken at 503-730-9424
- Report the date and precise location the place you caught the fish
- Report the tag quantity
- Launch the fish unhurt
As previously, when you catch a pike that does not have a tag, you could take away the fish from the water and kill it.
“In that case, we all the time like to listen to exactly the place and when these fish had been caught. The scale of the fish is all the time good info as nicely,” Lawrence mentioned. “If a tagged pike inadvertently dies, we’d nonetheless prefer to recuperate the fish in case the transmitter could be reused, so we ask of us to tell us if that occurs. We would like to have the fish or tag dropped at our workplace in Springville, however we are going to gladly make preparations to select it up from the angler.”
Northern pike had been first detected by the DWR in Utah Lake in 2011. As a result of pike are predatory and reproduce quickly, biologists are frightened in regards to the impact they are going to have on among the different fish species within the lake. June suckers are of explicit concern resulting from their precarious standing, however pike have the potential to impression sportfish within the lake akin to walleye, white bass and yellow perch.
June suckers, that are discovered solely in Utah Lake, had been downlisted from endangered to threatened in December 2020, an enormous accomplishment and main milestone of their restoration. Their continued restoration and eventual delisting from the Endangered Species Act might be jeopardized if the variety of pike within the lake expands to unrestricted ranges.
