Prevent Fish Kill in the Spring
Pond Deicing Can Help Prevent Fish Kill Keeping the pond open will help keep oxygen in the water, attract water fowl and help prevent fish kills in the spring. The most common cause of fish kills is suffocation due to lack of dissolved oxygen. Most dissolved oxygen is produced by algae and aquatic plants through photosynthesis. A lesser but also important source of oxygen in water is diffusion from the atmosphere, which is enhanced by wind-induced surface water turbulence. (Sallenave NMSU.edu) During the...

What does climate change mean for America’s $73 billion angling industry?
Inland fish play critical roles in North American ecosystems and economics: In the U.S. alone in 2011, freshwater anglers spent more than $30 billion on their hobby, generating $73 billion in economic output. And fish help keep nature in balance as they feed on aquatic plants and animals and in turn provide sustenance to iconic species such as eagles, bears and osprey. It’s no surprise, then, that as climate changes, 30 experts gathered last year in Bozeman, Montana, to explore implications for the well-bein...
Columbia River Gets a Vertical Fish Screen - case study
The Columbia River is huge and runs past deserts, towns, major cities and numerous recreation areas. It is a major fishery, as well. So this screen had to protect and exclude fish, handle natural and urban debris, and operate in a constricted space. We designed and installed large vertical fish screens with hoods. Now the irrigation canal is clean and clear of river debris. The fish are protected and workers have a lot easier job keeping it that way.This project included: Traveling Screen(s) Elevator Pump Tra...
