Salamander Infestation Clogging Irrigation Pond Pumps in Colorado

Salamander Infestation Clogging Irrigation Pond Pumps in Colorado

A 50x20 ft irrigation pond at 9,000 ft in Colorado has hundreds of salamanders plugging pump intakes annually. No fish present. Owner wants to stop the infestation.

Why They Thrive

No predators = population explosion. Salamanders eat insects and small organisms; abundant food and no predation allow unchecked breeding.

Biological Control

1. Introduce native fish that eat salamander eggs and larvae: trout, sunfish, or minnows (check CO Parks & Wildlife for legal species).
2. Feeder goldfish (from bait shops) are hardy and may survive winter; they consume eggs/tadpoles.
3. Koi also eat amphibian eggs but need larger ponds.

Mechanical/Physical

• Screen pump intakes with fine mesh (clean frequently).
• Modify habitat: reduce shallow, vegetated areas where they breed.

Fish introduction is the most sustainable long-term solution. Ensure the pond can support fish year-round (oxygen, depth).
