Abstract
An adjustable apparatus for fish spawning that is suspended below a buoyant float system at a predetermined depth. The apparatus is resistant to vertical motion by surface waves, and may provide additional aeration for egg species that require a high level of dissolved oxygen in order to incubate successfully. The apparatus may be constructed so as to provide maximum or minimum sunlight exposure to spawning bed nests and to accommodate the spawning depth and/or preferred bed slopes of certain fish species.
