FISHCULVERT is a manufactured stream bed that facilitates the passage of fish through culverts, over obstacles including perched outlets and small dams and up steep slopes.  Flow velocity is slowed down to critical levels for fish passage and a series of deep watertight resting pools are created. FISHCULVERT is available as a stand-alone flume (couloir) for perched outlets and small dams, an invert liner for over steep, smooth walled and deteriorated culverts or as the invert component of a new structural plate corrugated steel pipe culvert. Individual bolt in, watertight baffles are also available for all culvert pipe materials from 1200mm to 3000mm diameter. FISHCULVERT is fully welded steel that is co-polymer coated after fabrication. All CSP components and coating conform to CSA G401-14.

The standard FISHCULVERT is a stream-bed (invert only). Two sizes are available:               Small at 1393 x 3658mm (12′) sections (1600mm diameter) for 16% slope and Large at  1997 x 3658mm (12′) sections (2280mm diameter) for 12% slope.

Custom designs are available for 3% to 25% slopes in culverts from 1200 to 3000mm diameter.
