It's hard to get excited about a fish screen... unless you're a baby fish
We deliver fish screens:
- certified compliant
- robust design
- quality fabrication
- quick turn-around
Certificate of Build
All our fish screens come with a "Certificate of Build" which lists the specifics of the fish screen so that environmental inspectors can ensure compliance with Section 30 of the Fisheries Act. This includes a signed hard copy and e-copy to keep on file in the office as well as a laminated copy suitable for field inspections. In 1995, the Department of Fisheries and Oceans (DFO) passed a rule that all water intakes in fish bearing bodies of water in Canada be fitted with a protective screen. The purpose of this ruling is to protect fish from harm. As all levels of government in Canada are becoming increasingly aware of the importance of our marine ecosystem, they are enforcing the use of properly designed fish screens on all water pumps used in industry, construction, agriculture and by people with in-lake water pumps for domestic water use.
DFO “Fish Screen” Design For a fish screen to be effective, the screen mesh openings have to be small enough so that even baby fish do not get drawn into the water intake. As well, the screen’s total open area has to be large enough to allow adequate water flow to reduce the intake’s suction force - allowing an immature fish to be able to wriggle off the screen under its own power and not disturb organisms found in the bottom sediment. Keep in mind that these factors change based on the volume of the water pump's intake draw, the size of the screen area, the distance between the intake and the bottom sediment, and the species of fish likely to be affected. As a baseline, the DFO biologists agreed that the fish screen has to protect down to a 2.5 cm (1 inch) fish – which are called "fry" ... as well, the design has to account for fish species that are the weakest swimmers that may be found in the body of water containing the water intake. As a result, the Department of Fisheries and Oceans (DFO) developed a comprehensive guide outlining the standards to follow for every water intake fish screen. https://publications.gc.ca/site/eng/277803/publication.html |
Design and Fabrication Ultimately, your fish screen design is based on the pump intake velocity, species of fish to be protected, and the intended use. For a quote, we will need to know:
