HATCHERY OPERATIONS. 



m'donald lake. 



In 1921 the collection of red-salmon eggs aggregated 51,000,000, 

 from which 47,6-10,000 fry and fingerlings were liberated. In addi- 

 tion 150,000 eyed eggs were planted in two lakes adjacent to the 

 hatchery. The loss of eggs and fry together was 6.6 per cent. In 

 1922, 210,000 humpback-salmon fingerlings were liberated. In the 

 season of 1922 egg taking began on September 7 and was completed 

 on September 22, between which dates 25,000,000 red-salmon eggs 

 and 499,200 humpback-salmon eggs were taken. 



AFOGNAK. 



From the collection of 53,835,000 red-salmon eggs taken at Afog- 

 nak in 1921 there were shipped to the State hatchery at Bonneville, 

 Oreg., 5,200,000 eggs. Out of the remaining 48,635.000 there were 

 lost 2,614,000 eggs, and 46,021,000 fry were hatched. The loss of fry 

 aggregated 13,441,000, the plantings of red-salmon fry being 32,580,- 

 000. An epidemic in May and June, 1921, occasioned a very heavy 

 loss of fry. Its cause is thought to have been due in part at least 

 to low vitality of the parent fish occasioned by exceedingly low Avater 

 that occurred the latter pavi of the previous August and early Sep- 

 tember when the take of eggs was heavy. No doubt such reduced 

 vitality might have been transmitted from the parent fish to the 

 eggs and fry. 



In the season of 1922, in the period from August 1 to September 

 14, the take of red-salmon eggs was 61,790,000. Of these 10.678,400 

 were shipped in September, ^5,098,936 going to the Alaska Terri- 

 torial Fish Commission at Juneau, 5,045,000 to the Oregon Fish 

 Commission at Bonneville, and 534,464 to the State Fish Commission 

 at Seattle, Wash. In addition, 600,000 humpback-salmon eggs Avere 

 taken, of which 278,616 were shipped to the bureau's hatcher>^ at 

 Birds view, Wash.
