10 COMMISSIONERS OF INLAND FISHERIES. 



The brown trout may be readily distinguished from our common 

 brook trout by the presence of spots on, the back instead of wavy 

 markings. It has been known, under very favorable conditions, 

 to reach a length of thirty five inches and a weight of twelve pounds, 

 but five or six pounds is a very good average. 



It becomes mature when about two years of age and may live 

 to be over fifteen. The flesh is very digestible and nutritious and is 

 of varying degrees of red depending upon local conditions. 



In movements it is swift and will leap over obstructions like the 

 salmon. During the middle of the day it reposes quietly in deep 

 pools or shadow of overhanging bows and ventures out in the evening 

 and early morning. The best season for capture is from May to 

 September. 



"The species has long been known as one of the noblest of the 

 game fishes and its adaptability for capture with artificial flies, 

 because of its feeding habits, is well understood. " 



A consignment of 20,000 brown trout eggs were received by the 

 Commission this past year from the Pennsylvania State Fish Commis- 

 sioner, N. R. Buller. A very large proportion of these hatched and 

 about 15,000 fry, from 4 to 5 inches long, were recently distributed. 



It has sometimes been contended that it will drive out the speckeled 

 trout, but as the following instance indicates, both may thrive in the 

 same water. In this lake, in the early part of the season when the 

 water is chilly the common brook trout greatly predominates, but 

 when the water warms up the brown trout is caught almost exclusively. 

 It is not improbable that in those places where the brook trout seems 

 to have been driven out by the brown trout, changing conditions, such 

 as warmer water and absence of shade, have rendered the streams unfit 

 for the common form. 



Pennsylvania Bluegill (Lepomis pallidus Mitchill). 



Through the courtesy of the Pennsylvania Fish Commissioner, 

 N. R. Buller, the Commissioners obtained one hundred adult blue- 

 gills. Part of these are being held at Carolina in a small retaining
