Provo — As a part of an ongoing research launched two years in the past, the Utah Division of Wildlife Sources remains 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 have been positioned in Utah Lake illegally, anglers should kill any northern pike they catch that do not have a tag.
DWR biologists began tagging a few of the northern pike in Utah Lake and its tributaries in February 2020 as a part of a research to be taught extra concerning the seasonal places and actions of juvenile and grownup pike in Utah Lake, the Provo River, Hobble Creek and the Spanish Fork River. The research is predicted to run for a minimum of 5 years (till 2025).
Since northern pike usually spawn when the ice begins to soften, anglers might catch extra of the invasive fish at Utah Lake this time of yr.
The tagged northern pike have skinny, purple items of plastic connected to them. Tagged fish have been implanted with transmitters so biologists can monitor 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 might 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.”
For those who catch a tagged northern pike in Utah Lake or one in every of its tributaries, it is best to 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 prior to now, should you catch a pike that does not have a tag, it’s essential to take away the fish from the water and kill it.
“In that case, we at all times like to listen to exactly the place and when these fish have been caught. The dimensions of the fish is at all times good data as properly,” Lawrence mentioned. “If a tagged pike inadvertently dies, we’d nonetheless prefer to get well the fish in case the transmitter will be reused, so we ask people to tell us if that occurs. We might like to have the fish or tag dropped at our workplace in Springville, however we’ll gladly make preparations to choose it up from the angler.”
Northern pike have been first detected by the DWR in Utah Lake in 2011. As a result of pike are predatory and reproduce quickly, biologists are nervous concerning the impact they’ll have on a few of the different fish species within the lake. June suckers are of specific concern on account of their precarious standing, however pike have the potential to impression sportfish within the lake corresponding to walleye, white bass and yellow perch.
June suckers, that are discovered solely in Utah Lake, have 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.
