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 fish is not satisfied, however, notwithstanding its 
wide dispersal, is shown by 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 by 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 by 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 cultivation 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 
being the sea mullet, the most valuable fish of the South Atlantic and 
Gulf States; the common blue crab; the diamond-back terrapin, and 
the green sea turtle.
