Riassunto

Excerpt from Report of the Commissioner of Fisheries for the Fiscal Year 1910 and Special Papers

Taken as a whole, the work of the Oregon stations was satisfactory, although high water during the Spawning of the chinook salmon shortened the season and reduced the collections to slightly below those of the previous year.

At the Washington stations, where attention is devoted chiefly to the sockeye, humpback, and silver salmons and the steelhead trout, the work was augmented by the opening of two new field stations. In Alaska, where the sockeye salmon is propagated, the yield of the two hatcheries was. Highly satisfactory, especially the Afognak sta tion, operated for the first time this year.

The lake-trout, Whitefish, and pike-perch work of the Great Lakes stations, while not equal to that of some seasons, gave better results than had been anticipated in View of the obstacles encountered. Potent factors in the shortage at the Michigan stations were the unusually early spawning season, followed by unfavorable weather, and the necessity of complying with recently enacted state legislation, which stipulates that the operations of the Bureau must be supervised by the state fish and game warden's department and that all eggs must be taken and fertilized by fishermen licensed by that department, thus placing the work in the hands of inexperienced men. Compliance with the provisions of this law curtailed the output of Northville and its substations fully one-fourth. The law also prohibited pike-perch collections on the St. Clair River, one of the Bureau's most productive fields in past years.

At the Duluth station the weather and other conditions were favor able, permitting increased lake-trout work, but Whitefish and pike perch operations on Lake Erie were materially interfered with by storms, although the poor collections of the latter species were offset to a great extent by the superior quality of the eggs secured.

The lobster output from the three marine stations was about equal to that of 1909. The impounded stock at the Boothbay Harbor sta tion was stripped in April, and though the lobsters were in vigorous health the average yield of eggs was smaller than usual, due, it is believed, to their greater activity in the pound during the mild winter and the consequent shedding of many eggs. The construction of two substantial lobster pounds during the year places this station on a greatly improved basis. At the Gloucester and Woods Hole stations.
