Nurseries and Planting 



Some ten years ago the Commission prepared and distributed a 

 small pamphlet which was intended for the dual purpose of giving in- 

 structions to the uninitiated for planting fry and to encourage the for- 

 mation of anglers' clubs. The book was quite generally distributed with 

 the result that most of those interested became expert in the work of 

 transporting and planting fry. In the last biennial report of the Com- 

 mission this educational campaign was carried a step in advance by 

 advocating nurseries for the young fish, not necessarily extensive ones, 

 but sufficient in extent to form a resting place, a place where food 

 floating in the stream would move more slowly and where the fry 

 would not become a prey of larger fish. 



The plan of building a small dam of loose rocks to retard the flow 

 of the stream, of utilizing the small streams, the spring sloughs, the 

 shallow water at the sides of the larger streams can not be too forcibly 

 impressed upon the minds of those who plant fry. 



Every organized club should have a thorough examination made of 

 the streams in which it is interested and should construct the dams, 

 or have suitable designated places for planting so that the plantings 

 made may have the best obtainable results. The club should have a 

 permanent record, with maps and every year results of previous plant- 

 ing should be noted for future reference and as a guide to their suc- 

 cessors. It would be a great aid to the State Commission if good maps 

 of all the streams and rivers in the State could be had, and made a part 

 of the permanent records of the office. From these State maps, copies 

 could be sent to each hatchery covering the streams supplied with fry 

 from that particular hatchery. In the course of a very few years ac- 

 curate knowledge would be available as to results obtained if the
