SALMON AND TEOUT IN ALASKA. 53 



and their larvae, the larger on Crustacea, mainly an amphipod. In 

 several of each size were masses of intestinal worms. 



It is stated that small salmon are seen in the seines throughout 

 the canning season, but mainly in the earlier part. It will be noted 

 that the larger specimens were obtained in June, and that after Jul}^ 3 

 no collection of sockeyes was made from the cannery seines. It may 

 be that the continual hauling in time frightens them away; but it 

 seems more reasonable to believe that with increasing age they move 

 farther out from shore. The vast numbers observed in June must 

 be the yearling migrants from the lake. As to what becomes of 

 the fry of the same season after reaching salt water, there is no clue, 

 and can be none until search is made for them with small-meshed 

 nets. 



The oTily other specimens in the collection of interest in this con- 

 nection are 2 males of 91 mm. and 5 females 84 to 104 mm., average 

 92.4 mm., taken in Karta Bay June 26, 1897. These contained mainly 

 insects; some had also Crustacea, and one had a few young flatfish. 



THE KING SALMON. 



It is a significant fact that in the collections at hand there occurs 

 but one young king salmon taken in salt water. It would seem 

 there should have been some in the Karluk Beach collections if the 

 species is accustomed to tarry near its parent stream. They are 

 sometimes taken in San Francisco Bay and the region outside the 

 straits, but none of these examples have become part of the Bureau's 

 collection. They have been reported also from the i-egion of I{j1- 

 hsnoo, Alaska. The example mentioned is a 215 mm. male, which 

 was taken with the cohos (see below) at the Loring cannery wharf 

 August 2, 1904. As this was preserved for a colio, it is possible 

 that others of the 45 mentioned below were of this species. 



THE COHO. 



The young coho in salt water is more easily observed than the 

 other species. It readily takes the hook, and apparently is less 

 timid than the others in approaching surface and shore. In 1904 

 45 were taken at the Loring cannery wharf August 2. They aver- 

 aged 190 mm. (158-226). On July 10 at tlie same place about 30 

 were taken. No measurements were made except of the largest, 

 which was 138 mm. On August 2, 1905, a scattered school came 

 about the Albatross while anchored at the extreme head of Yes Bay; 

 26, averaging 202 mm. (152-237), were taken with a hook over the 

 ship's side. Only a few, 6 or 8, would appear at once, and they 

 took the hook baited with bits of meat, etc., very shyly in the per- 

 fectly clear water. Most of the stomachs contained ofl'al from the 

 ship's messes; 5 contained fishes up to 65 mm. in length, all that
