ABSTRACT:
An offshore brine shrimp cyst harvesting device providing for the gravity flow of the cyst rich layer of brine into a collection vessel, followed by pumping therefrom and dewatering by a sluice and pressurized means before deposition into porous cyst storage bags. The collection vessel is characterized by an adjustable knife edge inlet dam or weir, allowing the ingestion of the top layer without mixing or roiling so that the cyst concentration is as high as possible. According to one aspect of the invention, the height of the inlet control edge may be automatically controlled with respect to the surface of the water, as by floats or other water depth sensing devices.
