able eggs wei'e secured, tbe soasou's total amounted to only 3.250.000. Duriuic 

 the year needed repairs were made to the station boilers and pumps, and alt 

 batteries and steam and water pipes were repaired and painted. The jias 

 boat was overliauled, and painted inside and outside. New furnace lining 

 and boiler fronts were placed on the Shea neater boiler, and changes were made 

 on water pipes of deck pump. The hull of the boat was scraped and painted..

[J. P. SxYDER, Superintendent] 



A supply reservoir, 75 by 75 feet in dimensions and 7 feet deep with concrete 

 retaining walls, was completed during tlie year; and four bass ponds, each 

 exceeding an acre in size, were nearly completed. A new trout nur.sery con- 

 sisting of a hatchery, office, meat liouse. four ponds, and some open-air 

 trougiis was constructed during the year near Gracy. N. Y. This establish- 

 ment is being operated in conjunction with Cornell University management^ 

 and in addition to the production of several hundred thousand trout during 

 the year it was used as a base for the conduct of various feeding, rearing, 

 and other experiments under the supervision of Dr. G. C. Embody of the 

 university. In addition to the substations referred to below, the Gape Vincent 

 station supervised the work of cooperative nurseries located at Adams, Malone. 

 Arena, and Oneonta, all in New York State, and at Averill, Vt. The combined 

 output from these projects amounted to 108,120 fingerling and yearling trout, 

 and 228,000 trout of various sizes were in stock at the end of the year. 



The unusually small egg collections of commercial species secured for 

 stocking tlie Cape Vincent hatchery were made under very discouraging con- 

 ditions. By a decision of the Ontario fisheries authorities the prolific egg- 

 collecting fields along the north shore of Lake Ontario were no longer accessible 

 to the bureau, while unusually severe storms in New York waters of the lake 

 prevented the lifting of nets for a period of 10 days just at the height of the 

 spawning season. This storm period was followed imnietliately by intense 

 cold, causing all bays to freeze over and necessitating the discontinuance of 

 commercial fishing for the season. In the face of such an outlook whitefish 

 and Cisco egg collections were reduced to 1.23G.000 and 57.340.000, respectively, 

 while less than 2,000,000 lake trout eggs were taken. During the spring spawn- 

 ing season 6,300,000 pike-perch eggs and 3,000,000 yellow-perch eggs were 

 obtained and incubated. The station received from outside sources the usual 

 number of brook trout, rainbow trf)ut. and Lfich Leven trout eggs to cover 

 distribution requirements in New York and adjacent territory. 



Watertoini {N. Y.) cooperative suhstation. — The facilities at this substation 



were improved by the provision of additional hatching troughs and the t'on- 

 Btruction of a cottage. The output consisted of 449,750 trout fingerlings Nos. 



2 and 3, and 780.826 trout of different species were being carried in ponds and 



troughs at the close of the year. 



BarneveUl (N. Y.) cooperative substation. — As in past years the fish-cultural 



work at this substation was under the joint supervision of the bureau and the 



Utica chapter of the Izaak Walton League. Its output of fi.sh consisted of 



129,125 brook and rainbow trout of various ages, and 226,389 trout fingerlings 



and yearlings were on hand as the year closed. 

 Ithaca {N. Y.) substation. — This project was constructed in the course of the 



past fiscal year, but it has had no output as yet. On June 30, 1930, there were 



on hand 194.072 trout of various sizes. 



Swanion {Vt.) substation. — The run of pike perch was disappointing and only 



63,800,000 eggs of that species were taken. The collections also included 



94,380,000 yellow-perch eggs and 6,750,000 of the white sucker, the latter being 



obtained for the Pennsylvania Fish Commission. 



RESCUi: OPERATIONS 



Water conditions in the upper Mississippi River field were such 

 that the salvage of stranded fishes from the overflowed areas resumed 

 its role as one of the most important activities of the La Crosse 

 (Wis.) field headquarters. The work was started during the month
