COMMERCIAL FISHERIES OF ALASKA IN L905. 11 



Gravel Bank. — Fishermen sometimes visit this small bank, which 

 lies about 16 miles southwest from the southern end of Hagemeister 

 Island, and they state that large cod are abundant there. The depths 

 are from 16 to 20 fathoms. 



The Albatross investigations were not carried north of Cape Newen- 

 ham. According to Petroff, in the Tenth Census, codfish have been 

 reported at a few points along the Arctic coast, but no banks have been 

 located, very likely because no efFort has been made to find them. 



Unalaska Harbor, etc. -Fishermen have reported cod banks in the 

 neighborhood of Unalaska Harbor, but the investigations of the Alba- 

 tross do not seem to sustain the claim. The cod fishing directly off 

 Chernoffsky Bay is said to be excellent. 



On the southern side of the Alaskan peninsula are the following 

 banks : 



Davidson Bank. — This bank was discovered about 1870 by Prof. 

 George Davidson, of the United States Coast and Geodetic Survey, 

 after whom it is named. It lies south of Unimak Island, and ex- 

 tends westward from the neighborhood of the Sannak Islands to about 

 the longitude of the southern entrance to Unimak Pass (about longi- 

 tude 164° 40' W.). Its eastern end is continuous with the shoal 

 water surrounding the Sannak Islands; its area was estimated at 

 about 1,600 square miles. 



Sannak Bank. — To the east and southeast of the islands of the 

 same name lies Sannak Bank, somewhat elongate in shape and 

 trending in a general way northeast and southwest. It is estimated 

 to have an area of about 1,300 square miles. 



The region between Sannak Bank and the Shumagin Islands was 

 only partly surveyed, but about 1,800 square miles fairly well adapted 

 to fishing were covered. 



Shumagin Bank- Ikying to the south and southeast of the Shuma- 

 gin Islands, with its outer margin following approximately the trend 

 of the coast line formed by the adjacent islands, is Shumagin Bank, 

 which has been traced westward to about longitude 159° 52' W., but 

 probably extends farther in that direction; east of the Shumagin 

 Islands it reaches north to the latitude of Big Koniuji Island. Its 

 width inside of the 100-fathom curve varies from 15 to 35 miles, while 

 its area has been estimated at about 1,800 square miles. 



From the Shumagin Islands to Kadiak Island the area was only 

 partially surveyed, but the work done indicated the existence of sev- 

 eral fishing banks. 



Albatross Bank. — Oil the southeastern side of Kadiak Island is 

 Albatross Bank, extending the entire length of that island as well as 

 in front of the Trinity Islands. At the eastern end it is practically 

 continuous with Portlock Bank. Along some portions of the coast, 

 as in the neighborhood of Sitkalidak Island, the bank is separated
