The eggs,, when laid, float at the surface, where they are driven about by wind and tide. Doubtless a large percentage of the eggs do not hatch, through failure of fertilization and by being stranded. The eggs are very small, their diameter being only /g- to ^ of an inch. The artificial impregnation and hatching of Spanish mackerel eggs were first accomplished in 1880, since which time the propagation of the fish has been taken up on a number of occasions, although the work in any one season ha...s been comparatively limited. The serious diminution in the supply of this species in certain sec- tions seems to call for its artificial cultivation whenever it can be taken up without detriment to the propagation of other more or equally important fish. In the work of artificially propagating this fish recourse has been had to the nets of commercial fishermen for the supply of spawn and milt. Chesapeake Bay has been the seat of the principal operations, which have been conducted by the steamer Fish Hawlc.
