if you are willing to set-up a separate tank just for the adults alongside the main culture tank. Keep the top of this isolation tank exactly even with the top of the culture tank, and position an air lift tube in a corner of the adult's tank so that it returns water to the main culture tank, while a siphon tube in the opposite corner maintains the water level (see diagram) between the tanks. The air-lift tube should be sheathed with plankton netting or nylon screen with a mesh size (800 microns) that will restrain the adults while allowing the larvae to pass through unimpeded. Likewise, the end of the siphon tube should be covered with 500 mM plankton netting that will allow newly-hatched brine shrimp to pass through but not the juvenile mysids. Adjusting the air lift so it produces a slow, gentle, steady flow of water will automatically deposit the juvenile shrimp in the main culture tank while keeping the adults isolated in the adjacent tank, thereby eliminating cannibalism.
