.HATCHERY REBATES. 



Under the la^v 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 pa3'ment 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 

 alHdavit showing the number of red and king salmon fr}^ 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 

 Crovernment in payment of taxes and licenses as aforesaid. 



Rebates due private hatchery operators are shown in the following

HATCHERY OPERATIONS. 



m'donai.d lake. 



In 1919 a collection of 9,752,000 red-salmon eggs was made at the 

 McDonald Lake station, from which 9,«i87,000 fry were hatched and 

 planted in contiguous waters. There was a loss of 365,000 eggs and 

 fry, or approximately 3.S per cent. 



>io eggs were collected at that station in 1920, owing to the fact 

 that the water-sup|)ly 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 tiiis work could be done sati.sfac- 

 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 liureau's 

 station at Quinault, Wash., and another of 3,000,000 to the Oregon 

 State hatchery at Bonneville. P>om 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- 

 tciriber 24. Spawn taking was stopped at that time by high w.-iter, 

 which damaged the retaining racks and allowed the escape of all un-
