PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1935 417 



trout eggs were hatched, part of the fish being used in stocking rearing 

 ponds constructed by the United States Forest Service. The State 

 of Minnesota furnished a Hniitod number of pike-perch eggs during 

 the spring. 



At the Cape Vincent, N. Y., station eggs of whitefish, lake trout, 

 and hdvc herrmg, yielding slightly over 8,000,000 frj'-, were obtained 

 from local fishermen. The main activities here are now concerned 

 with the propagation of game fish, particularly smallmouth bass, 

 and the administration of the three substations where trout are 

 reared. This work has contmued to be of increasing importance. 

 The pilve-perch hatchery on Lake Champlain at Swanton, Vt., was 

 operated jointly by the States of Vermont and Connecticut. 



The work at the Put in Bay, Ohio, station was closelv tied in with 

 that of the State hatchery. The Bureau collected 51,000,000 white- 

 fish eggs, which were hatched and distributed from the State hatchery. 

 During the sprmg over 500,000,000 pike-perch eggs were collected 

 by the Bureau's force, with State facilities being used for hatching. 

 The dock at the Bureau's station has disintegrated to the point where 

 it is no longer safe for use. The Bureau's vessel Shearwater is now 

 operated by the State, serving both hatcheries. 



MARINE SPECIES 



At the Boothbay Harbor, Maine, station one of the steam pumps 

 and boilers was replaced by an electric pump, adding greatly to the 

 efficiency and economy of operations. A new hot-water system was 

 also required and installed as a result of this change. The flatfish 

 propagation was conducted in the usual manner. However, a larger 

 number of brood fish yielded a smaller number of eggs than during 

 the previous year. Opejations with the cod and haddock consisted 

 of fertilizing and planting on the spawning grounds eggs taken in 

 connection with commercial fisheries. The 729,000,000 cod eggs and 

 the 120,000,000 haddock eggs thus handled were really a bj^product 

 recovery. 



At Woods Hole, Mass., a new water-supply suction line was in- 

 stalled. Due to shortage of funds, no cod were propagated, but 

 144,000,000 floimder fry .were produced, together with a limited 

 number of mackerel. 



The Gloucester, Mass., station was reopened early in July after a 

 9-month closure. Considerable work was required in overhauling 

 boilers, pumps, fish-cultural equipment, and in renovating the build- 

 ings, all of which were deteriorated. Everything was placed in 

 readiness to permit propagation of pollock during the winter months. 

 Part of the one-half billion eggs secured were planted on the spa^\^l- 

 ing grounds directly from the fishing boats, the balance being incu- 

 bated at the hatcheiy. In the spring the work of planting fertilized 

 cod, haddock, and flounder eggs was taken up. Spawmtakers placed 

 aboard cormnercial fishing vessels encountered imusuaUy favorable 

 conditions, and large numbers of eggs were obtained. This station 

 is of chief value in maintaining a local inshore fishery. 



ANADROMOUS SPECIES OF THE ATLANTIC COAST 



The propagation of commercial species native to east coast rivers 

 was formerly much more extensive, but changing conditions accom- 

 panying development and industrialization have rendered such work
