452 U. S. BUREAU OP FISHERIES 



abundance of large-mouth bass, and the status of the supply of food 

 present for these fish. It had been alleged that the lake, which at 

 one time Avas drained and then reflooded during recent years, was 

 overpopulated, and that some of the fish should be removed. 



It was found that although bass were numerous, food, sucli as 

 minnows, young fish, and crustaceans, was scarce. It was found, 

 furtliermore, that tlie bass w^ere mostly in an emaciated condition 

 and were heavily parasitized, principally with the copepod of the 

 genus Lernaeocer^a. Although adults Avere numerous, there were 

 practically no young bass, indicating cannibalism. It was recom- 

 mended that, although adult bass were numerous, the fish be left in 

 the lake, partly because they were parasitized yncl partly because 

 virtually no young bass were present. Under the circumstances, it 

 seemed clear that with tlie limited amount of sport fishing permitted, 

 the population would soon be reduced naturally until a "biological 

 balance" wotild be reached, as has happened in other recently flooded 

 areas previously observed by the investigator. 



EASTERN TEXAS SURVEY 



Dr. Hildebrand identified a collection of fish for R. T. Richey of 

 College Station, Tex. The specimens were collected in eastern Texas, 

 in connection with a stirvey made by Mr. Richey for the Game, Fish 

 and Oyster Commission of Texas. The identifications are to be 

 used in a report on the stirvey. 



OTHER COLLECTIONS 



In connection with the stttdy of pollution of inland waters, Dr. 

 M. M. Ellis made collections of 452 specimens of small and young 

 fishes. The specimens were taken in many different sections of the 

 United States, from Maine to South Carolina and from Montana to 

 New Mexico. Dr. Hildebrand, assisted by Louella E. Cable, 

 identified 69 species in the collections.
