made during the year were the addition of a bathroom to the cottage occupied 

 by the apprentice fish-culturist and the rebuilding r)f the woodshed attached to 

 the superintendent's residence. 



LOUISVILLE (KY.) STATION 

 [Herman O. Hesen, Superintendent] 



Electric fixtures were installed in the cottages occupied by the superin- 

 tendent and the fish-culturist ; and repairs were made on station buildings, 

 ponds, and grounds as needed. The L type of outlet was installed in six of 

 the ponds, and much time and labor were expended in mending leaks in the 

 ponds and the sewer lines. All work outlined above with the exception of 

 installing the electric fixtures was performed by the station personnel. The 

 output of 412,157 fry and fingerling smallniouth bass indicates a smaller output 

 than in the previous year, but if the 1030 production of 143,750 largemouth 

 bass fry and fingerlings is taken into consideration the combined total exceeds 

 the 1929 output of both species by a substantial margin. The records show 

 that in past years very small results have followed the attempts made to 

 propagate largemouth bass. The past year's output of the species was pro- 

 duced in one pond less than three-fourths of an acre in area, and the yield is 

 considered good. The Hesen bass trap was used in making the collections. It 

 seems very evident that the Louisville station is well located for the work in 

 whicli it is engaged, both the climatic and the water conditions being well 

 suited to pond cultural operations. 



The year's distributions also included 1,280 bream and 2,740 rock bass, all 

 fingerlings, in addition to 1,500 rainbow trout. The rainbow trout were 

 obtained from the White Sulphur Springs (W. Va.) station for a special 

 plant in Kentucky waters. 



Owing to limited pond acreage the rearing of fish to the fingerling stage 

 is not practicable at this station. Such fingerlings as were produced the 

 past year were fish that had escaped capture in the breeding ponds when the 

 fry distribution was made. The provision of additional pond facilities would 

 permit of a material increase in the output of fingerling fish from this field. 



MAMMOTH SPRING (ARK.) STATION 

 [Dell Brown, Superintendent] 



The usual work of keeping the station grounds in good condition was per- 

 formed by the station force. Concrete floors were put in the fuel house and 

 the workshop of the oflSce building. The ornamental fence was painted and 

 600 feet of new fencing was built. The 8-inch portion of the station water 

 main was replaced with a 10-inch pipe and valve, and made possible a con- 

 siderable addition to the water supply. Of a total of 52 nests of the small- 

 mouth black bass observed in the spring, only 36 were productive. The sea- 

 son's output of this species amounted to 58,000 fry and 35,139 fingerling fish. 

 The schools of young bass of the largemouth species were unusually good, and 

 a total of 205,500 fingerlings and 4,000 fry of that species was distributed. 

 There was also a satisfactory output of rock bass. In addition to the station 

 fish-cultural work over 650,000 pond fislies. principally blaclv bass, were pro- 

 duced at four cooperative units in whose work the station actively participated. 

 The most important of tliese establisliments was the Arkansas State hatchery 

 at Lonoke. 



ORANGEBURG (S. C) STATION 



[S. A. Scott, Superintendent] 



A 2-story frame building, 27 by 60 feet in dimensions, was constructed. 

 This building provides room for a garage, meat room, tool room, and work- 

 shop on the lower floor and the upper story is used for storage space. The 

 two small buildings formerly used as a garage, stable, and tool house were 

 torn down, and a foundation was completed for a new ofiice building, which 

 will include in addition sufficient room for sleeping quarters and storage space. 

 The superintendent's residence was painted inside and outside and the porches 

 screened. All brood ponds were thorouglily cleaned during the fall and winter, 

 the mud and vegetation in them removed, and tlie ponds sanded and graded
