Spawning bed

Spawning bed

A spawning bed is an artificial bed constructed by wildlife professionals in order to improve the ability of desired game fish to reproduce. Increasing the spawning ability of a fish population may reduce pressure on a fishery and improve the productivity of supplemental stocking from fish hatcheries.

In the inland waters of North America, a typical spawning bed will consist of a series of concrete boxes filled with aggregate gravel. The concept is credited to the Kentucky Department of Fish and Wildlife. Joe McFarland, "Making Bass Beds", "Outdoor Illinois" XVI:5 (May 2008), pages 16-17.]

In some cases, especially in salt water, an artificial structure may significantly alter underwater morphology and create an artificial reef. Some vessels have been deliberately sunken, especially in salt water, in order to provide a destination for divers. In some of these cases the artificial reef also serves a supplemental purpose as a spawning bed.
