56 SALMON AND TROUT IN ALASKA. 



In Admiralty Inlet, A^Hiidby Island, on June 30, 1903, many young 

 dog salmon were taken in a shore seine on gravel bottom. Of these 

 13 of each sex were preserved, the males averaging 99 mm. (83-117), 

 females, 98 mm. (78-122). In none of the 9 examined were any fry 

 found. They were feeding wholly on plankton material, Crustacea, 

 principally amphipods, and Sagitta. They appear to have been 

 schooling alone. 



In Otter Bay, Pender Island, British Columbia, 11 dog salmon 

 were preserved from the collection of May 31, 1895. These averaged 

 a little over 70 mm. and contained Crustacea. 



June 29, 1897, 4 dog salmon, 2 of each sex, averaging about 56 mm., 

 were taken at Loring, it is believed in a seine haul on the seining 

 beach of Roosevelt Lagoon. They contained onl}^ insects. These 

 specimens, considered in connection with those obtained at station 2, 

 noted above, point toward a continuance of some of the young of 

 the dog salmon in brackish water for a period and suggest the desira- 

 bility of investigating such waters with suitable gear. A haid was 

 made in Roosevelt Lagoon on the night of October 1, 1905, but no 

 salmon were obtained. 



At Thome Bay, July 5, 1897, many dog-salmon j^oung were taken 

 in seine hauls on the beach just below the river; 64 of the specimens 

 pre males, averaging about 65 mm. (42-82), and 84 are females about 

 2 mm. longer (44-83). The food in those examined was Crustacea, 

 mainly ostracods. A few smaller ones taken in the river mouth were 

 feeding on insects. In Karta Bay, June 26, 1897, dog, coho, and 

 sockeye young were taken in the same hauls. Of the first, 19 males, 

 about 60 mm. average, and 10 females, about 53 mm., were preserved. 

 They were feeding mainly on insects and amphipods; a few contained 

 small flatfish, 1 being filled with them. 



In Dundas Bay, July 24, 1903, many young salmon — sockeye, 

 dog, and humpback — were seined on the tide flats. The specimens 

 of dog salmon are 4 males, about 75 mm., and 5 females, 82 nun. long. 

 They were feeding on Crustacea; a few had eaten insects and larvse 

 in addition. The 3 humpback, 2 males and 1 female, average about 

 80 mm.; food the same as the other species. The 3 species were 

 apparently schooling and feeding together. 



In Pavlof Harbor, July 25, 1903, the seine was hauled at the mouth 

 of a small stream in deep water, gravel beach. Many young dog 

 salmon, a few cohos, sand launces, and other small fish were taken. 

 The specimens of the first preserved are 4 males, about 100 mm. long, 

 and 7 females, slightly smaller. Their food was Crustacea, except, in 

 one instance, a few flies. 



At New Morzhovoi, July 17, 1894, 34 dog salmon young were pre- 

 served. These average about 80 mm. in length. The stomachs con- 

 tain Crustacea and gastropods; only 1 had insects. These specimens 

 show the peculiar segregation of food noted in some sockeyes at
