THE MIGEATIONS OP PLAICE. 
In accordance with an arrangement made with the Committee ^ 
early in the year, certain of the fislies -captured at the trawling ji 
excursions were labelled and returned to the water with a view to id 
determining their migrations, and also some facts about their rate d 
of growth. Altogether 483 fishes were carefully measured (the n 
majority were also weighed), labelled and returned to the sea. This i 
year the experiment was practically confined to plaice, and the uj 
marked fish were liberated at all the trawling stations from Goswick M 
Bay to Blyth Bay. I 
This part of our work during the past season thus forms an i. 
interesting, if small contribution to the migration experiments c 
carried out during the year in the North Sea by the various !' 
countries under the scheme of international investigations, and has : 
in this respect, we understand, been not unwelcome. It has its ; 
own importance, moreover, in that it deals entirely with the fishes !• 
of the in-shore waters. We arranged with Mr. Garstang, who is in i 
charge of the investigations relating to the southern part of the i; 
North Sea, to exchange the results with regard to the fishes we ) 
have labelled, and we have thus a much better chance of learning if 
any of our specimens migrate from the district. An instance of 
this (No. 804) will be seen in the accompanying table. We have i 
to thank Mr. Garstang also for tlie labels we used in the early part t 
of the season.
