DISTRIBUTION OF FOOD FISHES, FISCAL YEAR 1906. 



decided upon, and have been adopted in government, state, and private 

 fish culture: 



Fry=a, fish up to the time the yolk sac is absorbed and feeding begins. 



Advanced fry=ei fish from the end of the fry period until it has reached a length 

 of 1 inch. 



Fingerlijigs =&sh. between the length of 1 inch and the yearling stage, the various 

 sizes to be designated as follows: No. 1, a fish 1 inch in length and up to 2 inches; 

 No. 2, a fish 2 inches in length and up to 3 inches; No. 3, a fish 3 inches in length 

 and up to 4 inches, etc. 



Yearlings =^sh. that are 1 year old, but less than 2 years old from the date of hatch- 

 ing; these may be designated No. 1, No. 2, No. 3, etc., after the plan prescribed for 

 flngerlings. 



The difierence in methods of hatching the different species is a 

 determining factor in the supply of particular fishes available for dis- 

 tribution, and consequently of the number allotted to individual appli- 

 cants. The area and character of the water to be stocked must likewise 

 be considered; the water area that would receive a million pike perch 

 fry would perhaps be assigned no more than 200 or 300 black bass 3 

 or 4: inches long, or four to eight times that many if the bass were 

 planted as fry. The explanation is in the fact that pike perch can 

 be propagated by the hundred million, while black bass, hatched b}'^ 

 other methods or collected from overflowed lands, can be produced 

 only in comparatively small numbers. The Bureau does not attempt 

 to assign any applicant more than a liberal brood stock of the basses 

 or sunfishes. With brook trout, which are distributed both as fry and 

 flngerlings, assignments of fry are twenty-five to fifty times larger 

 than assignments of fingerlings 3 to 4 inches long.
