The Bureau long since discontinued the cultivation of carp, and does 

 not favor the further indiscriminate planting of this species; that 

 the demand for the lish is not satisfied, however, notwithstanding its 

 wide dispersal, is shown }iy the numerous applications received from 

 all parts of the country for supplies of carp for private and public 

 waters. It is the practice to satisfy these requests l)y the substitution 

 of better native species, among which the cat-fishes may be mentioned. 

 The fishes of this family are adapted to such different conditions, are 

 so hardy and prolific, and are so wholesome, that they are among the 

 best fishes available for the stocking of certain waters. The demand 

 is increasing, and the Bureau is endeavoring to meet it ])y taking up 

 cat-fish culture incidentally and on a necessarily small scale at several 

 hatcheries; but the time seems to have arrived when a special station 

 for the cidtivation of the cat-fishes is required. 



Various water animals are now under investigation that may eventu- 

 ally lead to their wholesale propagation by the Bureau, among such 

 l^eing the sea mullet, the most valuable fish of the South Atlantic and 

 Gulf States; the connnon blue crab; the diamond-back terrapin, and 

 the green sea turtle.
