TRANSPORT OF OTA AND FRY. 83 



both fish and spawn might render their numbers, to 

 an extent, harmless. 



The larger fish are, the more difficult it becomes 

 to transport them. Fish so tenacious of life as eels, 

 tench, carp, and even jack, may be transported with 

 tolerable ease. The salmonidae require more care 

 and attention. In Holland, tench and carp are con- 

 veyed to market in wet moss, are put into tanks, and 

 if not sold are re-consigned to the wet moss, and taken

 best apparatus for moving the larger fish is Mr. Eyre's,

 pimip attached, by means of which air can be driven 

 through the water. ^ Thus the water is kept aerated 

 and wholesome. When this apparatus is put in 

 action, fish that have previously appeared sickly, and

 of the cylinder. A ring-net, to bring the fish up for inspection, 

 and a loose concave rim, to prevent splashing over, completes it. " 



The reader can extemporize a fish-carrier from a nme-gallon or 

 smaller cask ; this must be thoroughly sweetened in the first place.
