REARING OF THE YOUNG FRY. 



211 



In the morning feed them again, and when it is time to 

 start, transfer them to the tank or can which is to carry 

 them. For small quantities, say 1,000 or 2,000, I use 

 a twelve-gallon tin can. For larger quantities, say 

 5,000 or more, I take a seventy-gallon tank, a drawing 

 of which may be seen in the Massachusetts Report of 

 the Fishery Commissioners for 1868, Plate III. Fig. 6. 

 The tank has a pump attached ; but this is not worked 

 when small fish are carried. I use also a hundred- 

 gallon tank for moving still larger quantities. 



The tank for carrying fish, when filled with water, 

 is very heavy, and should have four iron handles on 



Conical Tank for the Transportion of Young Fry.
