III.— MIGRATIONS OF INSHORE FLAT FISH. 
In the report for last year I gave an account of the results of 
the experiments which had been made in connexion with the trawling 
experiments to determine the migrations of the inshore flat fish of 
the Northumberland district. 
The visits of the Stanley to the various trawling stations in 
1905 gave the opportunity for marking a number, principally dubs, 
in the earlier part of the season with the remainder of the labels we 
had procured in the previous year, and latterly with labels kindly 
supplied by Mr. Garstang of the Lowestoft Laboratory.

The total number of fish which have thus been marked and 
liberated in the Northumberland district are shown in the following

In addition to those which were recaptured in 1901, referring 
to the experiments of that and the previous year (v. rep. for 1001), 
a number have since been obtained, and are included in the follow- 
ing table wiiich completes the returns to February, 1906. 
Plaice. — None of the plaice marked in 1904 has been recovered 
(unless the one recorded lust belongs to that group), but the 
records in Table XIV. bring the number recaptured of the 470 
plaice liberated in 1903 to 70 :— 7 in 1903, 55 in 1904, 
and 8 in 1905. The latter are interesting since the fish have been 
free for long periods, have made conspicuous increments in growth, 
and have in the majority of cases migrated to great distances.
