26 FISH CULTURAL ASSOCIATION. 
For instance, striped-bass (Aoccus lineatus), although an ocean-fish, 
will not carry well when young in ocean water. They will also | 
soon die in fresh water, but in slightly brackish water they be- 
come nearly as manageable in confinement as their hardy cous- 
ins of fresh water, the black-bass (Grystes nigricans). The white- 
fish of the Great Lakes is an extremely delicate fish to handle in 
water simply, but in a thick slush, made of snow and water, he 
gives his attendant no trouble at all. Young eels, although a 
fresh water fish, are perfectly unmanageable when travelling in 
pure fresh water, and will die in four or five days, notwithstand- 
ing the utmost care and most diligent aeration of the water ; but 
put them into a tub with a few inches of muddy water, two or 
three grass-sods for them to crawl out on, they will prove the 
toughest travellers of all fishes, and require no care at all. They 
can, without doubt, in this way be sent anywhere over this coun- 
try with perfect safety. All of which goes to show that it is 
very essential to take the fish you travel with in the right kind 
of water. 
(6.) Keeping the water at a wrong temperature is a very 
fruitful source of disaster in carrying live fishes. If I were ask- 
ed to name what I thought was the most important of all con- 
siderations in travelling with fishes, I should say keeping the 
temperature of the water right. Air-breathing animals can sus- 
tain life through avery great change of temperature. Bears can 
live in a temperature ranging anywhere between 30 deg. below 
zero and 140 deg. above zero. Human beings can sustain a 
temperature in the sun of 130 deg.,.and when sufficiently clothed 
will endure the extreme cold of 50 deg. below zero; but I do 
not know of a fish that is not limited to a range of 50 deg. or 
less. Trout life is restricted to a range of temperature included 
between 30 deg. above zero and 75 deg. above zero. Shad do not 
possess a much greater range, and so with most if not all the 
fishes we are best acquainted with. Consequently the matter of 
temperature is a far more important consideration with water- 
animals than with land-animals. This is perhaps best exempli- 
fied in the carrying of the fish just mentioned, trout and young 
shad. The safe carriage of ‘either fismfor a week | or so:is tree
