supply for a few brief moments is sufficient to wipe out the hatchery contents 

 and the sportsmen's investments and convert the hatchery into idleness until 

 the following year, with housing facilities for the assistants on the premises 

 this condition would be overcome as the plants would never be left unattended. 



Most of the hatcheries also are in need of increased facilities for rearing 

 trout to fingerling size. A majority of the plants have an ample supply of 

 water to take care of the necessary expansion and as soon as sufficient funds 

 are available these plants should be developed to the full limit of their 

 water supplies. 



Fisheries Management Course 



With the cooperation of the State College at Bozeman and under the 

 capable instruction and guidance of Dr. C. J. D. Brown of the Zoology Depart- 

 ment, a short course in fisheries management was given to the personnel of 

 the State fisheries, and interested members of the U. S. Forest Service and 

 U. S. Bureau of Fisheries. A class of fifteen was in attendance. This makes 

 the first attempt of this nature in Montana and which proved to be excep- 

 tionally successful, much of the course was given to the study of the many 

 plants and animals which live in the water and their relation to the fish 

 population. The use of the microscope as an aid in determining the diseases, 

 and also ages of fish and classifying the many microscopic plants and animals 

 that exist in any body of water proved to be a valuable part of the session. 

 However, equally important was the instruction given on the methods of 

 procedure in taking the gas analysis of water with relation to the water 

 being a suitable environment for fish life. This included tests for dissolved 

 oxygen, carbon dioxide, PH and total alkalinity, these being considered as 

 the most significant. As a result of this course the hatchery men will be 

 able to go into the field and determine with a much greater degree of accuracy 

 the suitability of the waters for fish life which they wish to stock. 



Butte Anglers Maiden Rock Hatchery 



One of the most outstanding projects designed to cooperate in the restora- 

 tion and maintenance of Montana's fishing is the fish hatchery operated by 

 the Butte Anglers Club of Butte, Montana, which is under the able leadership 

 of William Carpenter, president. 



Mr. Healea is in charge of operations at the hatchery. The State Fish 

 and Game Department cooperates by supplying the number and species of trout 

 eggs best suited for the waters to be stocked in that locality. The eggs are 

 hatched and the fry reared and distributed under the sponsorship of the Butte 

 Anglers Club. The degree of fishing to be found in the waters of that locality 

 is ample evidence of the effectiveness of this institution, and the Butte 

 anglers are deserving of much credit for their constructive activities. 



Rental of Private Hatcheries for State Use. 



As the spawning season of 1936 at Georgetown Lake progressed it became 

 apparent that the State hatcheries would not be capable of handling the 

 "take" of Native eggs and steps were immediately taken to acquire the use of 

 such private hatcheries, whose water supply was found to be satisfactory. Two 

 hatcheries with favorable water conditions were located, one near Kalispell 

 and the other near St. Ignatius. A total of 1,279,096 eggs were allotted to 

 these hatcheries, from which they were distributed after hatching. It is hoped 

 that additional funds can be acquired which will permit the State hatcheries
