APPENDIX 
A RECORD OF SALMON-MARKING OBSERVATIONS 
IN SCOTLAND PREVIOUS TO THE OPERATIONS 
OF THE FISHERY BOARD IN 1896. 
Manrgine salmon for the purpose of gaining information as to 
their migratory movements and their increase in weight has been 
practised for a considerable time, Izaak Walton in his “ Compleat 
Angler” (1653) alludes to experiments of this kind in which 
ribbons were tied to the tails of young salmon, and by which it 
was ascertained that salmon return to the same locality after 
visiting the sea. Writers of a later date do not always specify 
the method of marking, although they state results which would 
be of great interest were the proofs of their infallibility absolute. 
A considerable amount of reliable information has, however, been 
obtained from time to time in Scotland—exclusively, I think, on 
migration and increase of weight—and I have attempted to collate 
this information in the form of a list with tables. I omit from 
the list references to smolt marking, as well as any records which 
are without such particulars as alone can render them of value.

1823. In March, Mackenzie of Ardross marked a grilse kelt of 
34 lb. The mark was of brass wire. 
In twelve months the fish was recaptured as a salmon 
of 7 lb., showing an addition of 34 1b. in weight. 
1824. Mackenzie of Ardross marked a salmon kelt. The mark 
was wire round the tail. 
In 1825 he reports it as having been recaptured 
* double the size.”
