The New Hampshire State Fish Hatchery is in Laconia.
Evidence is still lacking as to whether the 20 to 30 million fry annually added from the hatchery have appreciably increased the quantities of young plaice on the surrounding shores.
Several kinds of fish, among which are trout, salmon, grayling and white fish, inhabit many of the lakes, rivers and mountain streams, and a government fish hatchery at Bozeman, Gallatin county, restocks waters in which the supply has been diminished.
Four fjords were selected in the south coast of Norway in proximity to the hatchery, and the usual number of fry (10-30 millions) were planted in the spring in alternate fjords, leaving the intermediate fjords unsupplied.
But their abundance was equally striking in other fjords in which no fry had been planted, while in 1905 all the fjords were deficient in young cod whether they had been planted with fry from the hatchery or not.
