REARING FISH FOR DISTRIBUTION. 
By FRANK N. CLARK. 
At the twentieth annual meeting of the American 
Fisheries Society held in Washington, D. C., in May, 
1891, I read a short paper on the rearing and distribu- 
tion of trout from the Northville Station, giving the 
plan pursued, and some of the results attained. The 
members of the society present at that meeting will 
remember that the subject brought out quite a discussion 
concerning the practicability and feasibility of rearing 
fish for distribution. One of the arguments introduced 
against the work was the expense, some thinking the 
outlay would be so much greater than in the case of plant- 
ing fry; others that the trout accustomed to liver would 
not adapt themselves to other food. At that meeting I 
promised to give some figures and facts relating to the 
expense of rearing trout to the age of one year at the 
Northville Station. It must be borne in mind that the 
food used at this station for feeding fry is wholly beef’s 
liver, bought from the slaughter houses in Detroit and 
shipped by express to Northville. For the years 1890 
and 1891 we reared and distributed 250,000 yearlings; 
about one-half of them being lake trout and requiring at 
least one-half more food than brook, Von Behr, or Loch 
Leven trout. The cost of the food for this lot of fish 
was $740.00, making the cost for food per 1,000 $2.95. 
The cost for labor based on actual time was $600.00, or 
$2.40 per 1000. In addition to this amount. there 
should be added about $3.00 per 1,000 for expressage, 
draying and superintendence, making a total cost, when 
ready for distribution, of $8.35 per 1,000, or less than 
one cent each for yearling fish, and with facilities for 
rearing four times as many the cost as to labor would be 
much less per 1,000. 
Not only is the arguments from figures, strongly in 
favor of yearling plantings, but those drawn from well-
