ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1920. 48 
HATCHERY REBATES. 
Under the law of 1906 for the protection and regulation of the fish- 
eries of Alaska, the owners of privately operated hatcheries in 
Alaska are exempt from the payment of all taxes and license fees 
on their catch and pack of salmon at the rate of 40 cents per 1,000 
red or king salmon fry liberated, which is equivalent to the tax of 
4 cents per case on 10 cases of canned salmon. ‘This rebate is ob- 
tained by the operators filing with the clerk of the district court of 
the judicial division of Alaska in which the hatchery is located an 
affidavit showing the number of red and king salmon fry planted in 
the waters of Alaska in the year covered by the affidavit. The clerk 
of the court then issues certificates to the owners of the hatcheries 
for the number of fry liberated, and these in turn are accepted by the 
Government in payment of taxes and licenses as aforesaid. 
Rebates due private hatchery operators are shown in the following

HATCHERY OPERATIONS. 
M’DONALD LAKE. 
In 1919 a collection of 9,752,000 red-salmon eggs was made at the 
McDonald Lake station, from which 9,387,000 fry were hatched and 
planted in contiguous waters. There was a loss of 365,000 eggs and 
fry, or approximately 3.8 per cent. 
Yo eggs were collected at that station in 1920, owing to the fact 
that the water-supply pipe line had to be renewed, an entire comple- 
ment of new hatching troughs provided, and a new foundation put 
under the hatchery building. As this work could be done satisfac- 
torily only in the summer months, it was necessary to suspend fish- 
cultural work for the season. 
AFOGNAK, 
Out of the 79,178,000 red-salmon eggs taken at the Afognak station 
in 1919, a shipment of 7,000,000 eyed eggs was made to the Bureau’s 
station at Quinault, Wash., and another of 3,000,000 to the Oregon 
State hatchery at Bonneville. From the eggs remaining there were 
hatched and liberated in Afognak Lake 61,524,000 fry. The loss was 
7,654,000 eggs and fry, or approximately 9.6 per cent. 
In 1920 a total of 62,300,000 red-salmon eggs was collected by Sep- 
tember 24. Spawn taking was stopped at that time by high water, 
which damaged the retaining racks and allowed the escape of all un-
