7 28 EEPORT OF COMMISSIONER OF FISH AND FISHERIES. 



may be used. The receptacle, whatever it may be, should be suspended, 

 in order to avoid the disturbance of its contents by the incessant rolling 

 of the vessel ; such motion being prejudicial to the welfare of the fishes. 

 The fishes should also be fed, and a supply of suitable plants should 

 therefore accompany them. We append a translation of the specific 

 instructions of M. Coste, from whom, indeed, have been derived the 

 hints above offered. 



" 1. Very young fishes should be selected. 



"2. These fishes should be distributed among several receptacles. 



"3. Oare should be taken not to crowd too many together in one 

 receptacle. 



" 4. The water should be renewed partially or entirely whenever it 

 becomes necessary. 



" 5. It should also be aerated from time to time. 



" 6. The fishes should be fed whenever they shall seem to require it. 



" 7. The remains from the food which has been given to the fishes 

 should be carefully taken up from the bottom of the receptacle, and 

 removed within eight hours after feeding ; the dejections and other 

 impurities which would injure the water should be removed. 



" 8. Finally, the several receptacles should be kept in different places 

 and under various conditions.''
