Abstract: A floatable boom for concentrating brine shrimp eggs which are floating at or near the surface of a body of water. The floatable boom comprises a rigid, floatable tube, a skirt affixed to the lower portion of the tube and extending downward into the body of water, and a remotely controlled drive device for propelling the floatable boom through the body of water. The invention discloses two of the novel, floatable booms extending outwardly from a harvesting boat in a divergent manner, such that a wedge-shaped concentrating angle is formed between the booms. The invention further comprises a means of support for maintaining the wedge-shaped concentrating angle formed by the booms.

Abstract: A brine shrimp egg harvesting device is shown. The harvesting device includes wedge-oriented booms designed to concentrate the brine shrimp eggs which float at the surface of a body of water. The brine shrimp egg harvesting device also has a collector for removing the concentrated slurry of brine shrimp eggs from the water and depositing it in a collection tank. The collector comprises of scoops which may be attached to drive chains which rotate the scoops into and out of the water. As the scoop enter the water, they trap a portion of the concentrated brine shrimp eggs and water and convey the captured slurry to a collection tank for deposit. The brine shrimp egg harvesting device has a pumping system for transporting the slurry of brine shrimp eggs and water from the collection tank to one or more porous storage containers which filter out the water in the slurry.

Abstract: A method and device for harvesting brine shrimp eggs, wherein the method comprises the steps of positioning a concentrating funnel slightly below the layer of brine shrimp eggs at the surface level of a body of salt water; moving the concentrating funnel forward with respect to the eggs to collect a portion of the layer and pumping the slurry mixture of eggs and salt water to a porous receiving container which passes the salt water and retains the collected brine shrimp eggs. A device for implementing this method includes a platform and attached channeling structure with a receiving end and a smaller, rearward feeding end. This channeling structure includes a height adjustment mechanism for selectively raising and lowering a forward leading edge of the channeling device to a depth just below the egg layer. Plumbing hardware is provided to transport the egg and salt water slurry to a container for receiving the eggs.
