DISTRIBUTION OF FISH AND FISH EGGS IN 1909. 
7 
fishes, catfishes, yellow perch, and others — are 2 to 6 inches in length 
when taken and distributed. 
Eggs are distributed only to state hatcheries and, occasionally, to 
applicants who have hatchery facilities. 
SIZE OF ALLOTMENTS. 
The Bureau does not attempt to furnish to any one applicant more 
than a brood stock of fish for a given private pond or stream, it being 
expected that these will be protected until they have had time to 
reproduce. The number of fish in an allotment is, however, a variable 
quantity, depending upon the species and the age at which distrib- 
uted. Brook trout, which are distributed both as fry and fingerlings, 
are allotted in much larger numbers as fry than as fingerlings 3 or 4 
inches long. Pike perch, which, owing to there excessive cannibal- 
ism, can not be reared and are consequently distributed as fry, may 
be supplied in lots of half a million, where an equal water area would 
receive only 200 or 300 young bass from 2 to 5 inches long. These 
latter larger fish have a much better chance of reaching maturity 
than have the fry, and the actual value for stocking purposes of a 
few hundred fingerling bass may therefore equal many thousand times 
this number of pike perch fry.
