Sea Bass (Centropristes striatus).
Squeteague (Cynoscion regalis).
Quinnat Salmon (Oncorhynchus tschawytscha).

Steelhead Trout (Salmo gairdneri).

Yellow Perch (Perca flavescens).
American Lobster (Homarus americanus).
Of the foregoing species only the cod, winter flounder,
quinnat salmon, blueback salmon, steelhead trout, Atlantic
salmon, shad, and lobster are regularly cultivated. In addition
to the species named, a number of others, some of minor
importance commercially, have from time to time been propa-
gated by this Commission,

With regard to the results of artificial propagation as
addressed to the foregoing species, the following statements
may be made :

1. The propagation and planting of cod in the inshore
waters of New England have been emphatically successful,
very lucrative fisheries having been established on grounds
that had been entirely depleted or that had never contained
cod in noteworthy numbers previous to the work of the Fish
Commission. It is reported by persons outside of the Com-
mission, and not especially interested in its work, that an
increase in the shore cod catch amounting to fully 50 per cent.
in ten years has attended the hatching operations of the Com-
mission at Gloucester and Woods Hole, Massachusetts.
2. The abundance of winter flounder in the vicinity of
Woods Hole, to which place the hatching is restricted, has
been materially increased, as would naturally be expected in
the case of a fish whose movements are so limited.
