How do you get rid at least one fish from a pond?
The answer is not by digging a deep hole, but by simply painting your lawn with paint, according to a new study.
The practice is a common, yet controversial, way to keep unwanted aquatic critters from being dumped into rivers.
The new study published in the journal Aquatic Conservation suggests that it’s not the most effective way to get fish out of a pond, either.
Instead, the study suggests that the practice can be more effective in controlling weeds, particularly the ones that feed on fish.
“The most effective method to control weeds is to have a variety of landscaping that contains native vegetation and vegetation that does not compete with fish for food,” said study author Dr. William Hockenberry, an ecologist at the University of New Hampshire, in a statement.
That could mean creating ponds, a natural landscape that offers an array of plant life, or using landscaping designed to reduce weed growth.
“This is really an adaptation for the new environment in the pond,” he said.
A canalith is a type of water-loving fish.
It lives in streams, rivers, and ponds.
The water-filled, slimy animals feed on the aquatic plant material that grows along the water’s surface, and also on the insects that live in the water.
This allows them to easily grow into ponds and canals, where they can be a nuisance to fish.
This new study suggests canalith treatment isn’t the most efficient way to control weed.
Instead of digging a shallow pit, researchers suggest painting the pond with paint.
The study found that the process led to the most favorable results, with a decrease in the amount of weeds that were found in the treatment area.
“There was no reduction in weeds found in treatment areas that contained no natural vegetation or shrubs,” the study said.
“The effect was not as great when the treatment was placed at the surface of the pond.”
The researchers said that this study was the first to demonstrate that canalith-related problems can be reduced by using natural vegetation.
“Although this study provides new evidence, it does not resolve the question of whether natural vegetation has a significant effect on canalith population dynamics in a pond,” they said.
Hockenberries said that his team is continuing its research to better understand how canalith management works.
“I’m hoping that this paper provides us with some additional information,” he added.
