Fish Culture in Inland Waters 303 



satisfactory fishing. His advice is, however, to refrain from plant- 

 ing them in any stream or pond suitable for brook trout, or in 

 waters from which they can gain access to brook trout waters, 

 although it is doubtful if brown trout would thrive in numbers in 

 the colder trout streams. But some might live, and those which do 

 survive become competitors for the food of the brook trout, even if 

 they do not harm the latter directly. Furthermore, there are certain 

 waters which are intermediate between the best environment of brook 

 trout and the best for brown trout. In such places brook trout can 

 be satisfactorily maintained but if brown trout are added the brook 

 trout may succumb. This advice is given with reservations, however, 

 and is subject to revision in the light of further knowledge. The 

 present writer may be sentimentally influenced but he believes that 

 there is no better trout than the brook trout and that we should 

 maintain it whenever possible. 



Bean said that the fry of the brown trout are shipped in March 

 or April, the fingerlings from May to July, and are planted as in 

 the case of the brook trout. 



Steelhead Trout. The steelhead was not included in Bean's 

 (1916) list of fish propagated and distributed, but the list in the 

 Eleventh Annual Report of the State of New York Conservation 

 Commission for the year 192 1 included it. A table is also given 

 showing the numbers of fish distributed each year from January i, 

 1917 to December 31, 1921. 



Of steelhead trout fingerlings there were 284,660 in 1917; 74,100 

 in 1918; 142,900 in 1919; 466 in 1920; and 118,000 in 1921. 



Although steelhead trout have been planted as rainbow trout, 

 wherever they have been placed under the name of steelhead, one 

 is fairly sure of the species. At least it is known that the eggs 

 have been derived from Washington and Oregon fish which were 

 ascending the streams from the sea and that the question is not 

 as complicated as is that of the rainbow trout. There have been 

 successful acclimatizations of steelhead trout in eastern waters, 

 the most notable of which is its establishment in Lake Superior. 

 It is known to have become established in some small lakes also, 

 but in them appears seldom to attain a considerable size. How- 

 ever, the steelhead is not regarded as a suitable fish for streams 

 in which a permanent resident is desired and it is advised to plant 

 them in the large lakes only, and then only provided the waters 

 are not already stocked with native salmonids. As a game or food 

 fish, it should be remembered that it spawns in the spring and is 

 likely to be in poor condition during the usual trout fishing season, 

 and that it is in its best condition only in late summer and fall. 



As the steelhead spawns in running water the same cautions and 

 rules apply to planting the fish as in the case of others of like habits. 



Landlocked Salmon. All that Bean said of the landlocked salmon 

 was that only a small number of eggs of this species were obtainable, 

 through the United States Bureau of Fisheries, and all the fry were 

 planted by the Commission in Lake George.
