Shad being aspring spawning fish the eggs hatch in from three to nine days, and the treatment isdifferent from that of trout and other heavy, non-adhesive eggs. Shad eggs areplaced in a hatching jar of glass which admits water from the bottom and the pressureor flow is regulated to hold the eggs in suspension as it were. Trout fry are bornwith a large umbilical sac on which the fish feeds by absorption for from twenty toforty days and which to all intents and purpose anchors the trout fry to the bottomuntil the sac is nearly absorbed. Shad are born with a very small umbilical sac andswim away with it as soon as the fish is hatched. Codfish eggs, one-eighteenth of aninch in diameter, are bouyant, non-adhesive, and are hatched in a tidal hatchersupposed to represent, in the action of water in the troughs
