ARTIFICIAL PROPAGATION 199 



practical certainty have been expected to be seen. But even assuming 

 that there is some loss I cannot see that the hatchery bred stock should 

 suffer a greater loss than the wild stock, the whole conditions, so far as 

 one can judge, being in all essentials apparently identical. Where the 

 hatchery bred stock may suffer more is when hand feeding is resorted 

 to in the hatching box and subsequently in a rearing pond. I under- 

 stand that, until the little fish become accustomed to the food provided 

 many suffer from an inflammatory affection of the gills. 



As to the means of transport it will be found that the fry may be 

 conveyed safely and conveniently to their future home in large glass 

 wicker-covered carboys, such as are used in chemical works. The 

 carboys should be full of water to prevent jarring in transit, and not 

 crowded to excess with fish. Should there be risk of delay anywhere 

 en route, or the journey be long, fresh water should at intervals be 

 introduced. With ordinary luck the whole consignment will arrive at 

 and be transferred to the stream without mishap. We have found at 

 Luss that, if no great distance has to be covered, the fry can be quite 

 conveniently conveyed to neighbouring streams in ordinary galvanised 

 iron pails. 



I may conclude by saying that, while these notes are based upon 

 actual experience of hatching out sea-trout ova at Luss Hatchery 

 during some eleven seasons, Mr. Walter McDiarmid, the very intelligent 

 and competent manager of the hatchery, was at first indebted for much 

 of the success of his operations to "A Handy Guide to Fish Culture," 

 by Mr. J. J. Armistead, which was published in 1897, at the extremely 

 moderate price of one shilling by The Angler Limited, Scarborough. 

 Though dealing specially with trout this little Guide will be found to 

 be equally serviceable for the hatching of sea-trout, one more proof, 

 if any be required, of the close relationship, if not actual identity, of 

 the fish.
