DWR News Release
Earlier this summer, Utah Division of Wildlife Resources fisheries biologists offered some tips to help minimize impacts to fish while fishing at lakes and reservoirs during a drought. If you are heading to a river or stream instead, here are some tips to decrease stress on a variety of fish species and increase their survival when releasing them:
-
Use single hooks on lures and bend down the barbs for easy release.
-
Minimize the time you spend “fighting” the fish while reeling it in. Tired and stressed fish have higher death rates.
-
Try to minimize handling of the fish. It can cause the loss of scales, which can result in infection to the fish. Always wet your hands before touching the fish.
-
Minimize the amount of time the fish is exposed to the air, especially when the weather is hot. If you are using a net, you can often keep the fish in the water while removing the hook.
-
Use rubber or coated nylon nets to protect a fish’s slime layer and fins.
-
Quickly remove the hook with forceps or needle-nosed pliers.
-
If the fish is deeply hooked, don’t pull on the line. Instead, cut the line as close as possible to where it is hooked and leave the hook.
-
Allow the fish to recover in the net before you release it.
“When you are fishing when it’s really hot, it’s important to use appropriate-sized equipment,” DWR Sportfish Coordinator Randy Oplinger said. “It is fun to fish with lighter equipment, but it takes longer to land the fish and that just adds to the stress. Once you land a fish, try to do everything you can to keep the fish in the water and get the fish released as quickly as possible. That’s why we recommend keeping the fish in the water when you remove the hook, and it is probably best to avoid taking pictures of the fish when the weather is hot.”
Strategic stocking to help fish during drought
Similar to last year, the DWR is again strategically determining where fish will be stocked this year in order to either reduce or eliminate fish from being stocked into waterbodies where biologists think that summer fish kills are possible due to low water. The fish that were scheduled to be stocked into drought-impacted lakes and reservoirs will be relocated and stocked into other waterbodies around the state that won’t have low water levels. The DWR is continuing to monitor conditions in Utah’s streams and rivers and will make adjustments, if necessary.
“We try, whenever possible, to continue to provide a good fishing experience for anglers, up until we think that water levels will be insufficient,” Oplinger said. “Then, we want to reduce the number of fish in that waterbody by decreasing the number of fish that are stocked there. We are hopeful that anglers will catch and harvest most, if not all, of these stocked fish by the time water levels become so low that fish survival is impacted.”
How drought impacts fish species
Drought impacts fish by reducing the amount of water available in lakes, reservoirs and streams throughout the state, which is the primary habitat for fish.
“This smaller amount of water heats more quickly and warms to higher temperatures than when there isn’t a drought,” Utah Division of Wildlife Resources Sportfish Coordinator Randy Oplinger said. “Warmer water also holds less oxygen than colder water. The combination of high temperatures and low oxygen can stress fish, causing poor growth, disease and sometimes death. Drought conditions can also sometimes impact streams by reducing water levels to the point where fish are stranded in small, isolated pools with little to no flowing water connecting the pools. These isolated pools often warm up quickly and have low oxygen, causing fish to die. Luckily, we have not seen this happen yet this summer, but we are continuing to monitor our fisheries and will make stocking or regulation changes if they become necessary.”
