420 Fortieth Annual Meeting 



Chilforo and its mouth was given to me verbally by the 

 late Mr. Moncreif. According to this gentleman, while 

 he was on expedition going down the river about the middle 

 of the year 1908, the fishermen who fish with nets in the 

 river told him at different times they had on various occa- 

 sions caught strange fish with spots on fins and tails. I 

 believe these fish to have been landlocked salmon, resulting 

 from plants in Lakes Nahuel Huapi, Traful, Gutierrez, 

 Correntosa, etc., early in 1904. 



I might mention here that except the whitefish every 

 species of fish hatched at the Nahuel Huapi hatchery early 

 in 1904, and planted in the lakes and rivers and streams 

 of that region, has been found and identified, and I am 

 not at all discouraged because the whitefish has not been 

 found, as I do not believe it has been fished for in the 

 proper localities and under proper circumstances. The 

 whitefish is rarely ever taken on a hook, and then only in 

 very swift waters through some portion of a lake which it 

 inhabits, and to catch it is the work of experienced fisher- 

 men with the proper kind of nets. The brook trout are 

 propagating naturally in the streams in the Nahuel Huapi 

 region, and large quantities of small fish from 5 to 8 centi- 

 meters long are annually taken from irrigating ditches and 

 transferred to suitable waters by the "ayudante" in charge 

 of the hatchery and his assistants, thus saving thousands 

 of trout which would otherwise be lost by the drying up 

 of these ditches later in the season when the water which 

 flows through them is turned into other channels. 



In a report written by the "ayudante" at the hatchery at 

 Nahuel Huapi on May 14th of this year, he states that to 

 date he had collected a total of 122,500 eggs during the 

 month and that all but 26,000 of these eggs were from wild 

 trout taken from the Rio Nirihuah, Arroyos, Cordoba, Cha- 

 cabuco, Taylor, etc. A telegram from this same source on 

 June 6th reported a total of 390,000 eggs collected to that 

 date. It did not state the number taken from wild trout, 

 but probably more than one-half were from this source,
