AMERICAN FISHES IN ARGENTINA.

The following table shows the number of each species on hand on March i , 

 1907, and again on October i, 1907, with losses and plants made during this 

 period (7 months) : 



Record of Santa Cruz Hatchery, March i to October i, 1907. 



The Santa Cruz hatchery is supplied with water from two springs, which 

 do not run more than 125 gallons of water per minute, at a temperature of 48° F. 

 When the shortage of this water supply is considered, it is little less than remark- 

 able that we were able to hold the large numbers of 6 months old fish (about 

 30,000, the greater number being Pacific coast salmon) which we had on hand 

 November i, 1906 (see first table), and have them in a perfect state of health 

 on this date. In fact they were as healthy as possible on October i, 1907, one 

 year and six months after they were hatched. The very low death rate from 

 November i, 1906, to October i, 1907, will be found by referring to the last two 

 tables. The water supply of the Santa Cruz hatchery decreased greatly during 

 the summer of 1907-8 (months of December, January, and February), and the 

 fish on hand showing signs of disease, a number of each species were planted 

 during these months. 



On January 18, 1908, the fifth lot of eggs brought from the United States 

 to Argentina left New York, numbering as follows: 300,000 quinnat salmon 

 (Oncorhynchus tschawytscha) , 104,000 sockeye salmon {Oncorhynchus nerka), 

 90,000 silver salmon (Oncorhynchus kisutch), 75,000 lake trout (Cristivomer 

 namaycush), 75,000 brook trout {Salvelinus fontinalis), 30,000 rainbow trout 

 {Salmo irideus), 15,000 landlocked salmon {Salmo salar scbago), and 3,000,000 

 cod {Gadus callarias). I personally had charge of this consignment of eggs to 

 Southampton, England, being accompanied by Mr. Frank Brophy. The loss of 

 the cod eggs was almost complete when we arrived in England, hence I deter- 

 mined not to attempt to take any of these farther. The loss of other eggs was 

 very small indeed, having been less than one-half of i per cent from the time 

 they were packed until put on board the steamship Thames on January 30, en 

 route to Buenos Aires. The eggs were given over to Mr. Brophy's charge when 

 this ship left her dock on January i , and in addition to those already mentioned
