for hunting. No particular class is predomi- 

 nant in the limited sample taken (table 4). 

 Four of the five seals collected were taken 

 in western Alaska waters, and one young male 

 was collected in Unimak Pass. Most of the 

 seals were seen 20 to 30 miles south of 

 Tigalda Island. 



In the period 1-10 June a concentration of 

 seals was found 10 to 30 miles southeast of 

 Tigalda Island. Seals of both sexes and various 

 ages were collected; females predominated. 

 A 9-year-old male was the oldest of this sex 

 taken. Seals were common in Unimak Pass 

 only in an area approximately 10 miles north- 

 east of Akun Island. Three males large enough 

 to be distinguished as bulls were seen. On 

 10 June the seals seen in Unimak Pass were 

 moving northeastward towards the Bering Sea. 



Sixty-three percent of the 205 collected 

 from 11 to 20 June were pregnant females. 

 Five bulls were seen within Unimak Pass. 

 On 11 and 12 June seals were plentiful south- 

 east of Tigalda Island. On 13 June they were 

 less plentiful and those seen in Unimak Pass 

 were moving northwestward. On 14, 15, and 

 16 June, seals in Unimak Pass were not feeding 

 and were very evasive when hunted. Late in 

 this period seals again became numerous in 

 the area southeast of Tigalda Island. 



More than 80 percent of the 37 seals col- 

 lected 21-30 June were pregnant females. 

 Much of Unimak Pass was examined, and 

 most of the seals seen were moving north- 

 westward. Very few were seen southeast of 

 Tigalda Island on 21 June. The sea was rough, 

 however, and seals were hard to see. They 

 appeared to be numerous between Unimak 

 Pass and the Pribilof Islands, but here also 

 rough seas hindered observations. Animals 

 were observed feeding and also moving stead- 

 ily. 



Seals were not plentiful from 1 to 10 July. 

 The first post partum female was collected 

 on 3 July near St. George Island and the first 

 in Unimak Pass on 7 July. A large 12-year- 

 old bull was collected approximately 60 miles 

 southeast of St. George Island on 4 July. Only 

 two trips were made into Unimak Pass during 

 this period. 



Pregnant and post partum females were 

 taken in nearly equal proportions in the period 

 11-20 July. Immature females became rela- 

 tively more abundant. One mature bull 12 

 years old was taken. Seals were numerous 

 in the north central part of Unimak Pass, 10 

 to 20 miles north-northeast of Billings Head, 

 and in an area 10 to 15 miles southeast of 

 Tigalda Island. Eleven of fourteen collected 

 were immature. No movements of seals 

 through Unimak Pass were observed during 

 this period. 



No collecting was done in Unimak Pass 

 from 21 to 31 July. Some hunting was done 

 in the vicinity of the Pribilof Islands. The 

 seals collected were either bulls or post 

 partum females. 



Of 72 seals collected 1-10 August, 32 were 

 post partum females, 8 were nonpregnant 

 mature females, 24 were immature females, 

 and 8 were males. Of the eight males col- 

 lected, three were bulls 10, 11, and 12 years 

 old. Observations on two trips through the 

 area 10 to 20 miles north of Akun Island 

 disclosed a concentration of feeding and rest- 

 ing seals. In the center of Unimak Pass, 35 

 seals of mixed ages and both sexes were 

 found. Seven large bulls were seen but not 

 collected during this period. 



Most of the 196 seals collected from 11 to 

 20 August were post partum and immature 

 females. One pregnant female was taken (see 

 Anomalies section). Three large bulls 10, 13, 

 and 14 years old were collected in Unimak 

 Pass. A large concentration of resting and 

 feeding seals was found in two visits to the 

 northwest corner of Unimak Pass. A complete 

 survey was not possible because of storms. 

 Numerous immature animals were located 

 southeast of Tigalda Island. Three large bulls 

 were seen north of Akun Island. 



About 50 percent of the seals taken in or 

 north of Unimak Pass from 21 to 31 August 

 were post partum females. South of Unimak 

 Pass 15 of 23 seals collected were immature 

 females. The Bering Sea side of Unimak Pass 

 held a concentration of feeding and resting 

 seals. They were scarce south of Tigalda 

 Island and in Unimak Pass except in the north- 

 ern approach.
