Hen Cannot Rival the Fish.
Information concerning the number of eggs produced by various species of .fish has been limited mainly to rather rough estimates. According to the Allgemeine Fischerei-Zeitung, some careful counts were made last year at the Bavarian trout hatchery. The first investigations were in connection with common tr6ut and rainbow trout; 58 specimens of the former and 54 of the latter were stripped and the spawn counted. The and heavier fish were found to have the most eggs (ranging up to about 3,000), but the younger fish yielded a decidedly larger number of eggs in proportion to the weight of the fish. The experiments were repeated with perch (Perea fluviatilis), in this case the females just about to spawn being killed and the ovaries being removed and dissected. The number of eggs in perch ranged from 3,710 for a fish four inches long up to 30,480 for one 10.2 inches long; but in this species, also, the number of eggs per unit weight of fish is much larger in small than In large fish. —Scientific American.
