132 KEPORT OF COMMISSIONER OF FISH AND FISHERIES. 



October, 1901, Prof. B. W. Evermann made an examination of the lake 

 with reference to its fish fauna. The maximum depth, as determined 

 by numerous soundings, was 14.5 feet. Although fish food is abun- 

 dant, the larger fishes are limited in both species and indinduals. 



The following fishes were found to inhabit the lake: Common bull- 

 head {Aiaeiurus 7iebulosus)^ white sucker {Catostomus cornmersoriii)^ 

 chub sucker {Erlmyzon sucetta)^ roach {Abramis crysoleucas)^ eel 

 {Anguilla chrysypa)^ banded pickerel {Esox americanus), common east- 

 ern pickerel {Esox retiGulatus)^ and blue-gill sun-fish {Lepomis pallidus). 

 A few large-mouthed black bass were recently planted in the lake, and 

 the conditions seem favorable for their rapid increase. 



FRESH-WATER FISHES OP MAINE. 



In ac(;ordance with a request from the Debsconeag Fish and Game 

 Club that the waters composing the fishing privilege of the club be 

 examined to ascertain why trout attain only a small size and if the lakes 

 were suitable for the introduction of trout and landlocked salmon, 

 Dr. W. C. Kendall devoted the month of August to the study of 

 these waters. 



Debsconeag lakes are a chain of five or six small lakes, which from 

 the westward debouch into the West Branch of the Penobscot not far 

 from Debsconeag Falls and about 20 miles from Norcross. Other 

 waters not connected with this chain of lakes, but comprised within 

 the Debsconeag privilege, are Hurd Pond and tributaries and Rain- 

 bow Lake, besides a number of smaller ponds and streams. These 

 waters are not exclusively controlled by the club, being public waters, 

 but the club has camp privileges on all of them within certain town- 

 ships. The water area was found to be so extensive that only super- 

 ficial examination of all of them could be made, so most of the time 

 was devoted to First Debsconeag Lake and Ilurd Pond. 



Brook trout are apparently uncommon in Debsconeag lakes and 

 Hurd Pond, but very abundant, though of small size, in Rainbow 

 Lake; in some of the small ponds they occur in fair numbers. Togue 

 {Crktivomer nmnaycusli) are doubtless common; some of large size 

 have been caught, but only small ones of 2 or 3 pounds were obtained 

 during the month of August, and these only in Hurd Pond. There 

 seems to be a scarcity of species of the minnow tribe in some of these 

 lakes, and the fish faunas of the several bodies of water seem to difl'er 

 somewhat in character; for instance, the chub {Semotilus corporalis)^ 

 common in the Debsconeag lakes, was not found in Plurd Pond, but 

 there its place is taken ])y the brook chul) {Semotikis atromaculatus)^ 

 which, so far as ascertained, did not occur in the Debsconeag waters. 

 If the conditions prevailing in August obtain throughout the year, the 

 scarcity and smallness of trout is probably due to paucity of food. 



In order to obtain important information regarding small salmon 

 occurring in the East Branch of the Penobscot, mention of which was
