Samuel Blatchford, Manchester v. Commonwealth of Massachusetts…
“ If there be a liberty of fishing for swimming fish in the navigable waters of the United States common to the inhabitants or the citizens of the United States, (upon which we express no opinion,) the statute may well be considered as an impartial and reasonable regulation of this liberty; and the sujec t is one which a state may well be permitted to regulate within its territory, in the absence of any regulation by the United States. The preservation of fish, even although they are not used as food for human beings, but as food for other fish, which are so used, is for the common benefit ”
