the upper six ikthoms of water as the gear cnly fished to that depth. 



Uc A very high percentage of the salmon caught were traveling in 

 an easterly direction, regardless of wind or tide or distance off shore. 



5. Salmon were as abundant, if not more so, in the vicinity of the 

 Pribilof Islands as in any other locality along the Cape Kordvinof-Pribilof 

 Islands -Nunivak Island section line. 



6. It seems probable that some of the Bristol Bay salmon never mi- 

 grate south of the Aleutian Islands but remain in Bering Sea during their 

 entire ocean residence. 



7. While many of the salmon that have migrated south of the Aleutians 

 pass by the Shumagin Islands and Ikatan Bay on their return migration and 

 go through Unimak Pass enroute to Bristol Bay rivers and other rivers enter- 

 ing Bering Sea, it seems highly probable that many fish also enter Bering 

 Sea through other passes to the westward such as Akatan, Umnak, Araukta,etc. 



8. Most of the salmon caught in the offshore waters were actively 

 feeding at the time of capture. (A report on the food habits of the salmon 

 of this region has not yet been released, however the most common food 

 found in the stomachs was euphasiids and small fish). 



Operations in 19Ul 



In I9UI, only one vessel was engaged in experimental offshore fishing; 

 the American Star of 98 gross tons, 70.7 feet registered length, 20.5 feet 

 breadth and 9»2 feet depth (see figure 6). 



The gear used en this vessel was as follows: 700 fathoms of linen 

 gill net, 5 ply (2 green strans), 5-1/2 inches stretched measure, 91 

 meshes deep; 225 fathoms cotton gill net, 20/9 cable fine yarn, h inches 

 stretched measure, 125 meshes deep;- and 125 fathoms cotton gill net, 20/6 

 cable fine yam, 2-1/2 inches stretched measure, 200 meshes deep, making 

 one net 1175 fathoms long, 500 inches deep stretched measure. This net 

 "hung" about six fathoms deep. 



The reason for using three sizes of gill nets was to determine if 

 immature fish could be taken in the waters fished. Cotton webbing was 

 used in the smaller sizes of webbing owing to certain difficulties in- 

 volved in obtaining linen webbing of those sizes. The cotton webbing 

 was treated with a copper preservative to dye the webbing green and to 

 prolong its useful life. 



As fish had been caught in all areas fished in previous years it 

 was decided to run a section as far viest of Bristol Bay as fish could 

 be caught. Consequently, starting at Unimak Pass fishing operations were 

 carried on 300, U95, 650^ 755 a^d 87O miles ^ est of the B,];:i;stol Bay rivers.
