TRANSPORT OF LIVE SALMON. 



Page 197. 



Mr. Ashworth tells me, that on 20th Decem- 

 ber, 1862, he transported forty spa^vning salmon 

 twenty-three miles. He placed them in a large 

 tub, and then put the tub in an ordinary spring- 

 less cart, with wisps of straw between the tub and 

 the cart and the splashing about from the jolting 

 of the cart, caused the Y/ater to be well aerated, 

 &Q. Fresh was added at every opportunity. The 

 expense was very slight. The fish arrived at their 

 destination as lively as when they started, and have 

 deposited the spa^Ti, thus re-peopling a vast tract 

 of water. It should be recollected that fish carry 

 better in cold than hot weather. 



HOW TO TAKE THE OVA FROM THE FISH.

All fish hatching experiments will, of course, be 

 useless, unless the ova of the fish can be obtained 

 in a fit state to develop themselves in the hatching 

 boxes. I have already explained that the eggs of 

 the fish are commonly called the " hard roe '/' soft 

 roe, is the milt. It is by the contact of the milt 

 Avith the ova that life is imparted to what otherwise 

 would be simply a mass of inert albumen. The 

 object in view, therefore, is to place the milt and 

 the ova in such a position that the one shaU have 

 free access to and vivify the other. 



I have several times had an opportunity of per- 

 forming the operation, which, after all, is simple
