    BIOLOGISTS ANGLING FOR WALLEYE FISHERMEN



    Early spring walleye spawning attracts anglers, fisheries biologists

    PRATT — In late March and early April, walleye migrate to rocky shallows in Kansas reservoirs to spawn. At this time, anglers gather along rip-rapped dams hoping to catch large walleye by casting jigs, rattle traps, crank baits, and stick baits from shore. Some even wade to cast parallel with the shore. But anglers aren’t the only ones interested in this activity although their interests are at stake. Kansas Department of Wildlife and Parks (KDWP) fisheries biologists take advantage of the spawn to harvest walleye eggs, which are then taken to agency hatcheries where increased hatching success means more fish for anglers in years to come.

    This year, three reservoirs will provide KDWP with walleye eggs. Egg-taking will begin on March 21 at Cedar Bluff Reservoir, March 21 at Hillsdale Reservoir, and March 28 at Milford Reservoir. Nets will be placed to catch spawning females that provide eggs both walleye and saugeye hatching programs. Fall test netting revealed large populations of big walleye in these three lakes.

    Infestations of zebra mussels, white perch, and other aquatic nuisance species (ANS) in several Kansas reservoirs require special care during egg-taking to prevent the spread of these potentially-destructive species. All sperm and egg collection will take place on each lake and the fish returned to that lake immediately. Eggs will be fertilized at the lake, as well, so no fish will be moved.

    On March 14, KDWP biologists began catching male sauger and milking them for milt (sperm) for the saugeye hatching program. (The saugeye is a walleye/sauger hybrid.) Milt is preserved in vials that are taken to Milford Reservoir to fertilize walleye eggs.
    Biologists will work for the next few weeks collecting and fertilizing eggs, transporting them to KDWP's hatcheries at Farlington, Milford, and Pratt, and eventually stocking fish throughout the state. Some fry are stocked in hatchery ponds to be raised to fingerling size and stocked later in late May and early June. Others are stocked directly into lakes as fry.

    In addition to walleye, the Milford Hatchery will produce the saugeye. Saugeye grow faster and larger than sauger and are thought to be less prone to wash-out high flow-through reservoirs than the walleye. To prevent production of fertile saugeye that have the potential to breed with walleye already in a lake — and potentially diluting that walleye population's genetics — a "triploid induction" process is used on some of the saugeye produced. Triploid induction is a technique that allows genetic manipulation of a chromosome number to create a potentially faster-growing, but sterile, saugeye.

    KDWP's statewide harvest goal for 2011 is 77 million eggs, with a production goal of 37 million walleye, 8 million saugeye, and 1.2 million sauger. Because fewer than 5 percent of eggs hatch in the wild, artificial spawning and hatching is used to increase egg survival rates as much as 40-50 percent. When hatchery-bound eggs reach their destination, biologists monitor incubation closely. Water flows are checked to ensure constant but controlled movement. Water temperatures and oxygen content are also routinely checked. Dead eggs rise to the top of the jars and are siphoned off each day. With a water temperature of 60 degrees, hatching generally occurs on the eighth or ninth day of incubation. As the fry break out of their egg cases, they are carried upward by the water into large circular holding tanks where they are held for two to four days. Then they are ready for stocking.

    All this activity may not be high-profile, but it makes Kansas walleye fishing much more productive. And as waters warm and days grow longer in late March and early April, many anglers take their cue from fisheries biologists and enjoy the opportunity to take walleye from the shore.

    sah,

    Textbook temperature is 48F and usually during the third week of March. The spawn is triggered by both water temp and also photoperiod (length of day). Peak of the spawn usually occurs last few days of March and first few days of April. I have seen ripe, flowing females come from 42F water and as early as March 12th so there is deviation from the 'textbook' dates and temps.

    Default March 31 last day for park fee bargains

    If you haven't already bought your state park vehicle permits, you can save a few bucks if get them before March 31.
    ------------------------------------------------------------------------------------------------------


    MARCH 31 LAST DAY FOR PARK FEE BARGAINS


    Park users can save by purchasing permits before April 1
    PRATT —Visitors to Kansas state parks can save money by purchasing many permits before the prime park season begins on April 1. Permits purchased in the off-season — Oct. 1-March 31 — are valid for the remainder of the calendar year, and they are cheaper if purchased during this period.
    For 2011, state park vehicle entrance permit fees include the following:
    Off-Season (through March 31)

    • Annual camping permit — $202.50
    • 14-night camping permit —$87.50
    • Annual vehicle permit — $19.70 (senior/disabled: $11.10)
    • Additional annual vehicle permit — $12.20 (senior/disabled: $7.35)

    Prime Season (April 1-Sept. 30)

    • Annual camping permit — $252.50
    • 14-night camping permit —$101.50
    • Annual vehicle permit — $24.70 (senior/disabled: $13.60)
    • Additional annual vehicle permit — $14.70 (senior/disabled: $8.60)

    Costs listed include applicable service fees, except online purchase convenience fee. Annual permits are valid for the remainder of the calendar year whether purchased in the off-season or the prime season.
    KDWP's Parks Division operates a system of 25 parks and the Prairie Spirit Rail-Trail. Most state parks provide utility and primitive camping, as well as cabins, and are located adjacent to lakes or reservoirs. Most camping and utility fees remain unchanged, but daily and 14-day camping permits are cheaper if purchased in the off-season. In addition to camping facilities, parks offer boat ramps, courtesy docks, shelter houses, swimming beaches, trails, and a variety of other amenities. Parks also host numerous special events, such as concerts and festivals, throughout the year.
    More information on state parks is also available at the KDWP website, KDWP - KDWP. To reserve a cabin, click "Cabin Reservations" in the upper right-hand corner of the KDWP website.

    Default Two more kansas reservoirs infested with zebra mussels 6-30-2011

    TWO MORE KANSAS RESERVOIRS INFESTED WITH ZEBRA MUSSELS

    Boaters reminded of threat and prevention steps before holiday weekend
    EMPORIA – On Wednesday, June 29, 2011, officials with the Kansas Department of Wildlife, Parks and Tourism and the U.S. Army Corps of Engineers announced that zebra mussels have been found in Council Grove Reservoir in Morris County and Melvern Reservoir in Osage County. Adding the twelfth and thirteenth Kansas reservoirs to the infested list disappoints KDWPT aquatic nuisance species biologist Jason Goeckler because he knows the spread can be prevented.

    “We expected Council Grove Reservoir because zebra mussels naturally move downstream, and they were found in Council Grove City Lake last July,” Goeckler explained. “The Melvern infestation is a different story because it could have been prevented. I still think we can prevent further spread of aquatic nuisance species if lake users will follow a few basic precautions.”

    All un-infested Kansas waters are under continual zebra mussel surveillance by KDWPT staff. A lake user found a rock with a single adult zebra mussel attached at Council Grove, and the infestations were confirmed when staff found larval zebra mussels, called veligers, and adult zebra mussels at both lakes. Veligers are too small to see with the naked eye and suspend for several weeks in the water before sinking to the bottom and attaching to a hard surface. While they are suspended, zebra mussel larvae can be easily transported in flowing water or water moved in boats, bait buckets and through other recreational activities.

    Zebra mussels are native to the Black and Caspian seas in Europe. They are believed to have been transported to the Great Lakes in the ballasts of transoceanic ships. Since first being discovered in 1988, zebra mussels have spread quickly to other waters in the Midwest. Control is expensive and there is no way to eradicate them once they become established.

    While an adult zebra mussel is only about the size of a dime, the species poses a dire threat to our native fish and aquatic animals. One adult female can produce up to 1 million eggs per year, and zebra mussel colonies quickly become quite dense, attaching to any hard surface, including native mussels, crayfish, turtles, boats, docks, as well as water intake structures. They even attach to other zebra mussels, creating layered colonies up to 6 inches thick. Densities of more than 1 million zebra mussels per square meter have been documented in Lake Erie. In addition to the threat they pose to our environment, native species and water recreation, zebra mussels will cost water suppliers, power plants and other water-related businesses $1 billion each year -- costs we all help pay.

    Adult zebra mussels are filter feeders, and an infestation can dramatically disrupt a lake’s food chain by removing plankton native fish rely on. KDWPT biologists have documented decreases in body condition and abundance in several game fish species after zebra mussel infestations. Zebra mussel feeding habits may also increase the potential for blue-green algae blooms, which can be toxic to humans and animals. Dense colonies of zebra mussels make wading and swimming along shorelines dangerous because of their sharp shells. When zebra mussels die, the odor and shell fragments that wash up make any shoreline activities unpleasant.

    With this latest discovery, KDWPT will increase local outreach efforts through signage and information materials in an attempt to educate lake users about the dangers of spreading zebra mussels. All lake users are asked to help stop the spread of zebra mussels to another water body. Goeckler reminds all anglers and boaters to remember three simple rules: CLEAN, DRAIN, and DRY. Inspect your vessel for any zebra mussels before you leave the boat ramp area. (Zebra mussels are on the prohibited species list, which means they can’t be possessed alive. Having a live zebra mussel attached to your boat is a violation.). Drain all water from the boat’s livewell, baitwell and sump area (Drain any bait buckets, as well – never pour live bait into the lake, dispose of it on land.) Dry the boat and trailer for at least five days before putting them in another lake, or wash the boat and trailer with 140-degree water.

    “It’s important that lake users take the threat of aquatic nuisance species seriously,” Goeckler added. “If their spread is allowed to continue, our water-based recreation opportunities may be changed forever.”

    Zebra mussels are just one of several invasive species that threaten our waters. Prevent their spread by following the CLEAN, DRAIN, and DRY procedures and never move water or fish from one body of water to another. For more information about aquatic nuisance species, go to www.kdpwt.state.ks.us and click on the “STOP AQUATIC HITCHHIKERS” window on the lower left of the page.

    As much as I hate it CLEAN DRAIN and DRY didn't/wont work. Now theres talk that birds can spread the veligers. Its only a matter of time for Hillsdale if not infested already. Personally I hate the thought that I might be transporting them to somewhere else. The guards at Coffee County mist your livewells and motors with a 10% bleach solution. Wonder why that wasn't recremended? I mean if we wanted to slow the spread we should of applies a full court press.

    go dart,

    Clean Drain Dry CAN work in stopping the spread of ANS species but success relies on all lake users practicing the steps every lake, every time. Anything less than 100% compliance with Clean Drain Dry obviously compromises effectiveness of the ANS control program and increases the chance of infesting new waters.

    There's is a lot of TALK about birds or other animals spreading zebra mussels from lake to lake. Currently, there is nothing in the scientific literature indicating that birds can successfully transport zebra mussels. However, there are studies that show that birds/waterfowl CANNOT transport zebra mussels. If someone has some information on transport of zebra mussels by birds I would be very interested in seeing it!!

    KDWP has recommended a 10% chlorine wash for boats, trailers, bilges, livewells, and other equipment for years. Many anglers have expressed concern in putting bleach in livewells so emphasis has been put on hot water (140F) and drying equipment for at least 5 days.

    A 'full court press' is a great idea! Hopefully ALL team members will participate in the team objective of keeping ANS from spreading to additional lakes. It only takes one 'team member' to let the rest of us down.
