Fish Culture in Inland Waters 247 



Allegheny River, Great Valley Creek, Little Valley Creek, Quaker 

 Run system (figures 22, 23), Red House Creek and Wolf Run. 

 Twenty-six species of fish were collected, including three game fish, 

 — brook trout, rainbow trout and brown trout. 



Brook trout were recorded as abundant in the Quaker Run system 

 and a few were found in Wolf Run. A few rainbow trout were 

 found in Quaker Run, also a few brown trout, but the latter were 

 said to be common in Red House Creek. 



In August, 1922, a continuation of this Allegany State Park 

 survey was made more intensively by the examination of the Quaker 

 Run system by a party from the Roosevelt Wild Life Forest Experi- 

 ment Station, under the immediate direction of the present writer. 

 The aim of this survey, as in the case of that of the Palisades Inter- 

 state Park, was to work out upon a broad basis a general fish 

 cultural policy for the Park. Quaker Run was examined from near 

 its source down to the Park Headquarters. All of the tributaries 

 with the exception of Coon Run were explored, most of them from 

 their source to their junction with Quaker Run. The streams were 

 carefully examined in sections, each day a different section, and 

 detailed notes were made of the character of the streams and immedi- 

 ate banks. Collections were made of the fishes and aquatic inverte- 

 brates, with the aim of determining the abundance and distribution 

 of the various species of fishes, and the quantity of food for trout. 

 A rough survey was made of the dimensions of each section and 

 an effort was made to count the trout in each section, to which 

 census the clearness of the water and openness of a greater part 

 of the stream lent itself beautifully. In Quaker Run, brook trout 

 were found from the extreme upper limit of examination down to 

 the beginning of the open country just above " headquarters," and 

 in all the tributaries throughout. Only two adult brown trout and 

 one fingerling were seen, and only a few small rainbow trout were 

 observed in Quaker Run and these in the lower sections. 



This appears to be the first time that an actual census of trout of 

 an entire stream has been attempted. It is believed that a fairly 

 accurate count was made, and they were roughly classified by esti- 

 mated lengths as : fingerlings ; large fingerlings ; 4-5 inch, 6-'j inch. 

 8-9 inch, 10 inch trout; and up. Probably there are but few places 

 so admirably adapted to such work as in these brooks. It was hoped 

 that it would be possible to correlate the number of fish observed 

 with the numbers planted in different years, but the information con- 

 cerning the number planted was found to be unreliable. However, 

 if accurate records are kept of future fish plantings another census 

 would be of interest and value in relation to stocking and m.aintain- 

 ing the fish of the streams, and particularly as concerns the capacity 

 of the streams to support trout of any kind. This information would 

 serve as a guide for recommendations as to kinds and numbers of 

 trout to plant in the various waters.
