TRANSPORT OF OVA AND FRY. 85 



Fish are of course far more difficult to transport 

 when they are heavy in spawn, but by the above 

 means, within the last twelve months, the Thames 

 Angling Preservation Society have transported some 

 200 brace of fish, varying from half a pound to 

 two pounds' weight, for distances of from 100 to 200 

 miles at a time, the greater part of them in that con- 

 dition, with the loss of only four or five brace of 

 fish ; and these most probably were injured in the 

 net or in the taking from the net. 



The ova of salmon and trout may easily be hatched 

 even in a drawing-room, by means of very simple 

 apparatus, which need take up but little room and 

 a comparatively small supply of water. All that is 

 required is a small cistern, capable of holding a few 

 gallons of water, with a small stop-cock to regulate 

 the supply. Around this cistern may be coiled, as it 

 were, in lengths, a small permanent gutter, or way, 

 about an inch or two in width, and neatly gravelled. 

 On this the ova can be deposited. Each coil or 

 length, of course, must be lower than the other ; and 

 supposing the apparatus to be square, a little fall 

 could be contrived at each corner. This coil or 

 gutter, after passing two or three times round the 

 cistern, should end in a water tank ; and if the water 

 tank be surrounded with a cooler, and furnished wit!)
