422 U. S. BUREAU OF FISHERIES 



last year, due to almost constant rains, which broke up the bass schools, 

 and to cool weather. 



Ichthyophthirius developed at Neosho and became epidemic for the 

 first time in 10 years. Selective breeding of rainbow trout has been 

 continued along the lines previously reported. The distribution of 

 trout was adequate to meet all requirements for that section. 



At the Bourbon, Mo., substation the production of eyed rainbow 

 eggs was approximately the same as that of last season and the hatch- 

 ing and rearing of the rainbow trout has been most successful. This 

 substation is operated upon a cooperative basis by this Bureau in 

 connection with the owners of the property. By agreement the 

 Bureau receives 90 percent of all rainbow spawn. 



Owing to a reduction in the brood stock the output of the Man- 

 chester, Iowa, station was considerably reduced from that of last 

 year. Tliree thousand brood rainbow trout yielded 2,496,000 eggs. 

 Consignments totaling 2,000,000 eyed eggs were shipped to appli- 

 cants, State or Government establishments. The smallmouth black 

 bass and rock bass produced a fair yield of eggs, and 10,860 large finger- 

 ling smallmouth bass, and 7,500 rock bass were distributed. 



The Leetown, W. Va., station was engaged in numerous experi- 

 mental activities which are discussed in the Report of the Division of 

 Scientific Inquiry. However, over 600,000 fry, fingerlings, and adults 

 were distributed. The hatch of trout eggs was poor due to carbon 

 dioxide in the water supply. Other diseases were noted during the 

 year and appropriate remedial measures applied. The station pro- 

 duced its first hatch of bass and has experimented with the rearing 

 of the fry in trout ponds. Construction performed included the clay- 

 ing of the bottoms of seven bass ponds and the construction of one new 

 pond. Concrete bottoms were placed in two long trout raceways. 

 A dwelling for the director was completed during the year, and work 

 was started on a fish culturist's cottage. 



The new Lamar, Pa., station was in active operation although no 

 fish were hatched. Trout fry transferred from other stations were 

 reared, producing over 50,000 good-sized fish for distribution. Eight 

 circular rearing ponds and four 50-foot raceways were constructed, 

 and property lines were fenced. Several hundred feet of road were 

 constructed. 



The Flintville, Tenn., station has reduced its rainbow brood stock 

 with consequent reduction in egg take. Surplus fish were turned 

 over to the State. Production of pond fish was limited due to the 

 fact that wild brood stock from Reelfoot Lake had not become fully 

 acclimated. 



Operations at the Erwin, Tenn., station were of a routine nature. 

 Cooperative arrangements for the rearing of trout were in effect mth 

 sportsmen's organizations and the State. 



At the White Sulphur Springs, W. Va., station painting of the 

 station buildings was completed. A smaller number of eggs was 

 secured from rainbow brood stock than was the case the previous 

 year, but the percentage of the hatch was higher. Almost 100,000 

 pond fish were produced, an increase of 36,000. The station hatched 

 trout eggs for the State of West Virginia, as has been done previously. 



The total distribution of all species from the Wytheville, Va., 

 station was slightly below the previous year, but as a whole the year's 

 work was satisfactory. Large numbers of eggs and fish were assigned 

 to the States of Virginia and North Carolina.
