AQUATIC VEGETATION MANAGEMENT
Aquatic vegetation is vital to healthy aquatic ecosystems however over abundance of such vegetation can be detrimental to fisheries, water quality, access, and overall aesthetics.
Aquatic vegetation assumes a natural cycle in that it blooms in the spring, grows throughout the summer and dies in the fall and winter. Periodic algae blooms are also common throughout the spring and summer.
Although this cycle is natural, often times it must be managed to maintain a quality resource.
Aquatic vegetation produces oxygen during sunlight periods, yet consumes oxygen at night or low light periods and also during decomposition when it dies off. The consumption of oxygen can significantly reduce dissolved oxygen levels resulting in low quality habitat and even fish kills.
As vegetation decomposes it becomes organic sediment (black mud) which contains high levels of nutrients that act as a fertilizer promoting further growth of aquatic vegetation. Sediment accrual over time will reduce water depth, impact water quality, promote further vegetation growth, inhibit aesthetics, and release gases resulting in a rotten egg odor.
Liley Fisheries and Aquatic Consulting provides onsite consulting services to collect and identify aquatic vegetation, evaluate environmental conditions promoting excessive vegetation growth, and provides a long term vegetation management plan to best suit your aquatic resource.
A combination of biological, mechanical, and chemical management tools have proven to be the most effective solution to aquatic vegetation and water quality issues.
Pond Freedom - pond bacteria and barley straw powder
Freedom Blue - super concentrated pond colorant to minimize sunlight penetration and photosynthesis
Grass Carp (Diploid and Triploid) - fish species that consumes many aquatic plant species
Installing an aeration system for your pond or lake can be a very effective management tool to keep vegetation problems in check and provide optimal dissolved oxygen levels to promote a healthy aquatic ecosystem.
Liley Fisheries, Inc . uses a variety of algaecides and herbicides to control aquatic vegetation issues unique to your resource. LFI contracts with a State of Colorado licensed aquatic pesticide applicator who is available to apply chemicals at your request.
Cutrine Plus Liquid - A 9% chelated copper algaecide effective in controlling a wide range of algae including Spirogyra, Chara, Vaucheria, Cladophora, Microcystis, Ulothrix and Oscillatoria. When treated properly, water may be used for fishing, drinking, swimming, livestock, or irrigation immediately after application.
Cutrine Granular - Same active ingredient as Cutrine Plus Liquid. Very effective on bottom growing algae. Most effective when distributed evenly over problem areas at first signs of growth. Easy to apply with hand scoop or spreader.
Reward - A liquid aquatic herbicide effective on floating, submersed, and emergent aquatic plants. Target plant species include cattails, duckweed, and naiads. Concentration decreases rapidly after treatment as it is absorbed by organic materials, minimizing environmental risks. The following restrictions on water usage apply when treated with Reward: Drinking- 1-3 days, livestock consumption- 1 day, food irrigation - 5 days, non-food irrigation - 1-3 days.
Aquathol K - A concentrated liquid herbicide that effectively controls aquatic weeds on contact including hydrilla, milfoil, and curly-leaf pond weed. When used properly, it will not harm fish, birds or other aquatic life. Aquathol K dissipates quickly, leaving no residue, and will not bioaccumulate in fish or hydrosoil. The following restrictions on water usage apply when treated with Aquathol K: Livestock, irrigation, and domestic use - 7 days; fish consumption- 3 days.
Sonar - A liquid herbicide used for season-long control of submerged weeds and floating duckweed. Concentrated formula performs widespread control and attacks the roots of aquatic plants. Best results when applied in early spring. Not to be used for spot treatment. No restrictions on fishing or swimming; 14-30 day restriction on irrigation use.
