Worthington pioneered the physical fish guidance barrier. Worthington’s fish guidance systems have been highly effective guiding downward migrating fish such as salmonoid smolts away from dangerous water intakes and turbines. Our systems are physical barriers consisting of a floating element and an underwater guiding system that takes advantage of natural water flows to guide fish to a takeout point or bypass system.
Worthington Physical Fish Guidance Systems have achieved 92% guidance rates while minimizing bypass flows.

Worthington's fish-tight™ fish guidance systems are designed to achieve the highest guidance rates while minimizing bypass flows. Our staff fisheries biologists work closely with our clients to understand their needs. The results are common sense guidance systems at economical costs.
Worthington fish guidance systems are installed in Maine, Oregon, Washington State and California.
Maritime Security Barriers
A boat travelling 60mph covers 88 feet every second! If your barrier won't stop that boat in under 1-second, chances are the terrorist will be close enough to inflict serious damage. Talk to our experts to learn how a Worthington maritime security barrier can meet your force protection and port security needs.
