LIMNOCORRALS

The Facts About Limnocorrals

What are Limnocorrals?

Created by Winnipeg-based Curry Industries Ltd., Limnocorrals present a practical and cost-effective method with which to test fresh water for pollutants.

Limnocorrals are fabricated from a variety of plastic materials best-suited for the specific purpose of testing fresh bodies of water pollutants. The Limnocorrals is fabricated into a plastic tube that extends down to the bottom of a body of water. Once in place, it is anchored and sealed to prevent seepage. Kept afloat by a specially-designed flotation system, Limnocorrals are ideally-suited to the lake environment, allowing researchers to completely isolate their water sample. Today tests are being conducted on waters across Canada and the United States for such pollutants as acid rain, mercury, radiation and others so prevalent in our ecological system.

Lake Divider Systems

A lake divider curtain is used for the same purpose as a Limnocorral . However, this system can isolate a large body of water allowing large-scale testing with a wide range of testing procedures on an ongoing basis. The Lake Divider Curtain enables environmentalists to determine long-term effects of polluted waters on the complete ecological system including its impact on animal and plant life, water quality and the long-term effect on humans.

Fish Hatcheries

More recently a new use was found for the Limnocorral . The Limnocorral is now being used by fish hatcheries and wildlife associations in Canada as the most economical means of stocking lakes with a variety of fish species. The Limnocorral is first deployed in a designated lake best-suited for this method, then stocked with fertilized fish eggs in early May where they will remain contained until approximately the end of August. When the fish reach a length of approximately two inches, they are then released by dismantling the Limnocorral . The survival rate of the fish can reach 40% to 50%, compared to the 2% rate for fish released using conventional methods. The Limnocorral is the most cost-effective means of achieving a better result.
