of Oconomowoc) there are state fish hatcheries, the former for black bass.
There are Federal hatcheries at Swanton (for pike perch and yellow perch) and at Holden (for trout).
New York was in 1904 more extensively engaged in oyster culture than any other state, and was making more rapid progress in the cultivation of hard clams. In 1909 there were distributed from state fish hatcheries 1 531,293,721 fishes (mostly smelt, pike-perch, and winter flatfish); a large number of fish and eggs were also placed in New York waters by the United States Bureau of Fisheries.
The catch of herring was twice as much in 1908 as in 1907 and that of whitefish nearly four times as much in 1908 as in 1907; this increase was attributed to the work of the state hatcheries.
There were eight hatcheries in 1910 and the number of fish distributed from these during 1908 was about 662,000,000; they consisted chiefly of pickerel, yellow perch, walleyed pike, white fish, herring, blue pike, trout and shad.
