Biological Control of Lake Pests

Biological control of lake pests and unwanted vegetation is a viable choice that has many advantages over chemical extermination. First and foremost, the impact on the entire lake ecosystem is minimized and there is little to no chance of any beneficial species being destroyed unintentionally.
Second, the development of a lake ecosystem, maturing in its variety and diversity, could introduce myriad new ideas on lake usage.
Below are several types of fish highly recommended for biological control in a lake maintenance program.

KOI (Cyprinus Carpio)
KOI (Cyprinus Carpio)is a hardy fish, characterized by striking patterns and delicate coloration. These ornate carp consume a wide variety of foods (earthworms, snails, prawns, tadpoles, frogs and lettuce). Especially important in biological lake management, they can be used to control midge fly populations.

GOLDFISH (Carassius Auratus)
GOLDFISH (Carassius Auratus)is a peaceful, schooling fish that resembles carp. They are usually consumed rapidly by predator fish because of their smaller size and coloration. They are omnivorous, consuming both animal and vegetable material, live or dried food. In biological lake management, they are an effective agent in the control of midge fl y infestations, as they eat the burrowing midge fly larvae.

TILAPIA (African Cichlids)
TILAPIA (African Cichlids)is a robust, rapidly producing, tropical fish originally imported from east Africa. Presently, tilapia are grown for human consumption. In lake management, they are an excellent implement for controlling filamentous and chemical resistant, nuisance blue-green algae (lyngbya), as well as insect larvae and decaying organic material; they are also considered good forage for certain sport fishing populations, such as bass and catfish. Restocking tilapia annually is a necessity, since winter water temperatures drop well below their survival limits.

WHITE AMUR (Ctenopharyngodon Idella)
WHITE AMUR (Ctenopharyngodon Idella)is also known as grass carp, these fishwere originally imported from the great riversof China. White Amur are used extensively forbiological control of unwanted aquatic vegetation,thereby reducing the need for chemicalintervention. In Arizona, state regulations allowonly the certified triploid (sterile) variety.

OTHER fish options include:Fathead minnows, catfish, large and small mouth bass.  For information on stocking rates and prices, call Water Resource Management. We have the best prices in the Valley – guaranteed.
