(1964) discussed the coexistence of lake trout 

 and anadromous parasitic Arctic lamprey in

Arctic grayling, Thymallus arcticus (Pal- 

 la^).-- Arctic grayling were collected only in 

 the Naknek River system.''"^ We collected them 

 in Brooks River; Bay of Islands, Headwater, 

 Hidden, and West Creeks; Brooks Lake; and 

 South Bay and North Arm of Naknek Lake. 

 Fish in the lakes were usually taken near one 

 of the streams. Although their distribution 

 was spotty, grayling were seasonally abundant 

 in certain streams, particularly Brooks River. 

 One grayling was seined from the morainal 

 cut between Iliuk Arm and South Bay in 1962, 

 about 4,8 km, from the mouth of Brooks River. 

 Grayling spawn in Brooks River in May and 

 early June; we collected fry (19-22 mm, long) 

 from the river on July 11, 1963. Sport fishing 

 for grayling is common in Brooks River (see 

 footnote 4). 



Osmeridae 



Pond smelt, Hypomesus olidus (Pallas). -- 

 Pond smelt were collected in Coville and Gros- 

 venor Lakes; North Arm, South Bay, and Iliuk 

 Arm of Naknek Lake; and Coville River, 

 Although we did not find them in Brooks Lake, 

 we collected them in West Creek and Brooks 

 River just below the outlet of Brooks Lake, so 

 they probably live in the lake. Pond smelt are 

 apparently more widely distributed and nnore 

 abundant in Coville Lake than in other parts of 

 the Naknek systenn. 



Umbridae 



Alaska blackfish. Pallia pectoralis Bean.-- 

 Blackfish were collected in Coville, Grosvenor, 

 and Brooks Lakes; Bay of Islands and North- 

 west Arm of Naknek Lake; and West Creek 

 and the ponds at the head of West Creek, 

 Blackfish usually inhabit shallow tundra lakes 

 and ponds (Walters, 1955) or sluggishmarshes 

 along streams (Blackett, 1962). Normally they 

 are not considered to inhabit large lakes or 

 deep water. In Brooks Lake, where they ap- 

 parently are more abundant than anywhere 

 else in the Naknek system, blackfish are com- 

 monly caught in water 15 to 20 m. deep; at 

 this depth they are still within the range of 

 submerged vegetation, particularly Chara and 

 Nitella . A trap net set 8 m, deep on the bottom 

 of Brooks Lake near the outlet from July 5 to 

 September 9, 1963, took 583 blackfish. In gen- 

 eral, the occurrence and distribution of black- 



We received an unconfirmed report from sport fisher- 

 men in 1966 that they had caught grayling In Contact 

 Creek In the headwaters of the King Salmon River system. 

 Grayling are known to be common In the Ugashik River 

 system farther out on the Alaska Peninsula (fig. 1), so It 

 Is likely they also live In the King Salmon River system. 



fish in large lakes of the Naknek system seem 

 to be associated with submerged aquatic vege- 

 tation. 



Esocidae 



Northern pike, Esox lucius Linnaeus. -- 



Northern pike were pronninent in many small 

 lakes and ponds in the Naknek portion of the 

 monument. They also live in the large lakes 

 and streams but usually in areas of relatively 

 shallow, quiet water with aquatic vegetation. 

 Four such areas were Northwest Arm and Bay 

 of Islands in Naknek Lake, the Grosvenor 

 River Lagoon just below the outlet of Gros- 

 venor Lake, and backwater lagoons along lower 

 American Creek. Northern pike were also 

 collected in Iliuk Arm, South Bay, and North 

 Arm of Naknek Lake; Coville, Grosvenor, and 

 Brooks Lakes; Coville, Grosvenor, and Brooks 

 Rivers; and West and Hidden Creeks. Sn-ialler 

 lakes known to have pike populations include 

 beaver ponds at the head of Hidden Creek, a 

 series of lakes and beaver ponds at the head of 

 West Creek (Greenbank [see footnote 4] re- 

 ferred to the larger of these as "Pike" Lake), 

 Jo-Jo Lake, and a lake in the Savonoski Valley 

 about 3 km. east of the Ukak River that Green- 

 bank called "Murial" Lake. We did not sample 

 Murial Lake, but Greenbank did. 



Although northern pike now occur only rarely 

 in the Brooks River area, they may have been 

 abundant there in recent historical times. 

 University of Oregon archaeologists have col- 

 lected considerable quantities of fish remains 

 in aboriginal occupation sites near Brooks 

 River Falls. Considerable numbers of pike 

 scales were found in the remains, most of 

 which were fronn adult salmon. Radiocarbon 

 dates and stratigraphic series of volcanic 

 ash deposits indicate that most of these fish 

 remains were deposited from A.D. 1500 to 

 1800,'''* Several swamp and marsh areas along 

 the lower 400 m. of Brooks River now have 

 water in them only for a brief period in late 

 summer and early fall when the water level at 

 Naknek Lake is highest. A few centuries ago 

 when the mean water levels of Naknek Lake 

 were high, the pike habitat in the present 

 marshes and swamps was probably more sta- 

 ble. Under such conditions pike were probably 

 abundant in the area.

Longnose sucker, Catostomus catostonnus

 South Bay, and North Arm of Naknek Lake;
