When the fry begin to hatch, they burst the shells of the eggs and emerge tail first, wriggle themselves out and pass down through the wire meshes to the bottom of the trough. As soon as all the eggs have hatched, the trays can be removed. The egg shells must be feathered out to the lower end of the trough and finally brushed out over the tail screen, care being taken not to injure or l)rush out fry at the same time. Cripples, deformed ones and dead from unknown causes will be picked from the trough daily by use of the small scarf net and pickers. The eggs develop first into fry with an abnormally large stomach, called the umbiHcal sac, which is their "bread basket". This sac is gradually absorljed until the fry appear like the one illus- trated with almost no sac at all. At this period or soon after, it begins to rise to the surface of the water for food and snaps at floating particles. Unless you intend to feed the fry and rear 23.
