Abstract: A curtain of a boom for harvesting brine shrimp eggs includes mesh sections for directing a flow of water in a first direction such that an amount of the brine shrimp eggs swept under the curtain of the boom during a harvesting process is minimized and a bottom section located below the mesh sections for directing a flow of water in a second direction during the harvesting process such that debris in the water is swept under the curtain of the boom.

Abstract: A method, and associated apparatus, for drying harvested brine shrimp cysts for storage for subsequent hatching for fish food. The cysts are washed with fresh water, and strained through a sieve to remove foreign material, flotation separated to eliminate dead cysts, strained out of the water, dewatered centrifugally, and finally dried in a special apparatus which prevents any caking of the cysts together. The drying apparatus includes a drum with cyst-retaining porous walls, mounted on its side to rotate in a vented housing about its longitudinal axis. Drying air is blown into the rotating drum, exiting through the porous walls, drying the cysts without caking.
