REPORT OF COMMISSIONER OF FISH AND FISHERIES. LXXXIO 



Gnided by information from Mr. Blackford, Mr. Woodbury obtained, 

 at Ked Bank, X. J., on July 13, yearlings from 4 to 5 inches in length. 

 No fish of the year's spawning were obtained. Several hundreds of 

 these were successfully transported to California and placed in waters 

 there by Mr. Woodbury. 



It. The Black Bass (Micropterus). 



In accordance with the policy of the Fish Commission, no special ef- 

 forts have been made looking toward the introduction of the black bass 

 into new waters of the United States. All that has been done in this 

 respect has been performed either by State commissioners or by in- 

 dividuals. Without pretending to decide as to the expediency of such 

 introduction, the United States Fish Commission has surrendered this 

 department as stated. Its intervention, however, has been invoked by 

 various i)arties abroad, and on the 2d of July arrangements were made 

 to supply Count von Dem Borne, of Germany, with a quantity of these 

 fish. On September 30, Mr. William T. Silk reached Kew York to ob- 

 tain bass for Lord Exeter, of England, from whom he brought letters. 

 Mr. Silk was placed in communication with Mr. E. G. Blackford, who 

 assisted him in securing a supply from Greenwood Lake. These were 

 carried to England with but little loss, and divided between several 

 parties who had made preparations to take care of them. 



n. The White Perch {Morone americanas). 



The Quantico Station. — During the stay of the Fish Hawk at Quan- 

 tico there were taken in the shad seines 34 male perch and 39 female in 

 a ripe condition. These yielded 1,630,000 embryonized eggs. From 

 these eggs there were hatched 180,000 fry, which were deposited in 

 Quantico Creek. 



Record of perch-hatching operations conducted hy the United States Fish Commission steamer 

 Fish Haivlc, Lieut. Z. L. Tanner, United States J^avy, commanding, at Quantico Creek,
