3 089 P 15 4646 CANADA FISH EGG SUPPORTING SYSTEM Abstract of the Disclosure A system for supporting fish eggs including a waffle- patterned surface providing individual fish egg supporting apertures, The apertures are in a noncircular form to permit the flow of fluids and gases around the egg supported in each aperture. The apertures are spaced from one another a distance to permit the eggs resting in adjacent apertures to have a gap therebetween to prevent the fungus that might form on a dead egg in one aperture from spreading to an adjacent viable egg resting in the next aperture. The system can include stackable trays which permit numerous eggs to be held in a small volume. The apertures are of sufficient similarity in surface configuration to natural gravel beds to support the alevin in comfort to encourage maximum conversion of the egg yolk to fish tissue rather than wasting such nourish- ment on notion. The trays can be stacked within a raceway with a porous membrane upstream of and adjacent to the stacked trays to distribute the flowing water evenly throughout the stack.
