1854. The Duke of Atholl marked an 11 Jb. kelt on March 21. 
It was recaptured as a clean fish of 17 lb. near Montrose 
on August 24, 1854. 
1851 During those years a large number of fish were marked by 
to 
1872. 
the Experimental Committee of the Tweed Commis- 
sioners. The table which follows (pp. 152 to 156) is 
taken from the Tweed Salmon Reports, 1866. It is 
given in full, although it contains reference to a few 
marked smolts. I have added a column as to the 
nature of the mark used, so far as this can be determined 
from the Report. 
1857. On November 12, Mr. Buist, Stormontfield, river Tay, 
while netting for ova, marked 89 salmon and 78 grilse 
with copper wire (where on the fish is not stated). 
On September 6, 1858, one was caught in Largo Bay, 
134 Ib. in weight. No particulars of each fish seem to 
have been taken. 
1858. March 31, Young of Invershin reports that a grilse marked 
on that date was recaptured as a salmon of 8 lb. on 
August 2 in the same year. 
1859. The Duke of Atholl marked fish on the river Tay. A 
numbered copper disc, an inch in diameter, or] gutta- 
percha, ticket fastened by copper wire round the tail was 
used. The following fish were marked as kelts and re- 
captured as clean fish the same year :—

1860. Through the kindness of the present Duke of Atholl I am 
able to add particulars of another fish, the mark taken 
from which I have seen. I add also the lengths of 
the three fish above referred to.
