During the summer, aquatic vegetation produces large amounts of oxygen through the process of photosynthesis. Daytime dissolved oxygen levels can be well above saturation, even in warm water which tends to hold less oxygen as water temperatures rise. The flip side to the problem is the other end of the spectrum – winter. A fish kill experienced as cold temperatures cause ponds and lakes to freeze over. Low dissolved oxygen levels result from a combination of factors. The air/water interface is capped by the formation of ice, limiting the exchange of oxygen at the surface. This icy cover also reduces or completely eliminates sunlight from reaching any aquatic plant life that would otherwise produce oxygen through the process of photosynthesis. With no light available, aquatic plant life will begin to respire (consume oxygen) along with fish and other aquatic life and further increase the oxygen demand. The bacterial decomposition of organic material and bottom sludge also depletes oxygen levels. Ponds and lakes with an abundance of excess nutrients and organic sludge build up (eutrophic) are most susceptible to fish kill. These water bodies have a much higher latent oxygen demand so oxygen levels can drop very quickly if something goes wrong. Shallow ponds and lakes also tend to have more trouble with fish kill. These water bodies hold less water, so there is not much volume for oxygen storage.
are some common clues that something might not be
right with your waters:
• Low Clarity
• Unpleasant Odor
• Fish Dying
• Fish Gulping Air at Surface
Note: Cloudy, calm summer days can actually trigger a fish kill. Less oxygen is produced during the day due to less light available for photosynthesis and little or no wave action. With less oxygen dissolved in the water heading into night, there may not be enough oxygen available to sustain aquatic life until morning.
Ice Eater is shipped complete with suspension lines or, for the .75-hp & 1-hp models, the dock mount is available for purchase. Our products are designed to be taken out of the box, hung in place and plugged in. Ice Eater may be hung from a pier or boat. Two to three feet is the average operating depth. Our venturi design shroud is unique to our product. Based on the concept of using a short pipe with flared ends and a smaller middle section, a large amount of water is taken in through the bottom, forced through a narrower middle which allows for bigger thrust out of the flared top.
The Ice Eater was designed with several key factors in mind:
Preventing winter fish kills
In the same way humans need oxygen to survive, so do fish. When a pond or lake freezes over, the fish start suffocating since no new air can get into the water. Photosynthesis is cut short during the winter if a layer of ice is present. Not only can you lose stocked fish by letting the waters freeze over, but come spring you will have created an abundance of fish carcasses to cleanup once everything thaws, along with an undesirable odor.
No matter if you are an avid bird watcher or enjoy the hunt, waterfowl can be wonderful to enjoy during the winter months when you have unfrozen waters for them to play in. Ducks and geese utilize this open water for feeding, nesting, and protection during migration. Fowl are even attracted to bobbing decoys in the water.
Prevent damage to docks, boat launches, and boats
When water freezes into ice, it expands. The solid pressure of ice can do harmful damage to pilings causing them to lift or tilt. Serious damage can happen to boats themselves when they are docked for the winter.
Water quality improvement
The foundation to any healthy aquatic environment is oxygen that can be supplied by surface aeration systems. Our equipment propels the stagnant, stale water into the air to create big air bubble thus circulating the oxygen back into the water. Movement mixes the different temperature within the water which allows the overall temperature of the water to stabilize.
Duck Hunters can have a tough time depending on how fast or slow the fall changes over to winter weather. The slower the change the longer the season, but if cold weather strikes fast it can cut short the hunt. That’s where Ice Eaters & Mallard View Outdoors comes in - we have combined resources to find a way to keep your blinds open longer. Birds will keep migrating when there is no open water to be found. To remedy this problem Ice Eaters can be placed in the waters, prior to the hunt, to keep open sections of water. The more open water you can create, the better the chance that the flock will congregate to your blind. Shallow water and energy source might feel like a problem, but Mallard View offers both generators and stands to keep the Ice Eater out of the muck and running at full speed. The movement in the water doesn’t seem to bother the ducks – in fact, most hunters find that the ducks are attracted to the movement and the decoys are more lifelike since they move with the water.
