(5) The Winter Migrations. 
These other four lines of winter migration are :— 
IP 
2. 
Into Morecambe Bay. 
Into the Estuaries of the Mersey and Dee. 
3. Into “ Channel Course ” and the Red Wharf Bay Area. 
4. 
Towards the Isle of Man. 
About 70 fish were recaptured durimg the months of 
November-December. Considering the sizes of these plaice we 
arrive at some very interesting results. 
iF 
The majority of the smaller fish migrate in-shore 
into the shallow waters of the Ribble Estuary, 
and are caught as close to the land (in stake-nets, 
shank-nets, and trawl-nets) as fishing can be carried 
on. 
A smaller proportion of fish of the same 
range of sizes migrate into Morecambe Bay, round 
the north part of the Bay, and are caught in very 
shallow water. 
An equally small proportion migrate into the 
Dee and Mersey. | 
2. The larger plaice migrate in November-December 
to the west, along “Channel Course,” that is 
the track of vessels approaching Liverpool from 
Point Lynas. These fish are mostly caught off 
the coast of North Wales between Great Orme’s 
Head and Anglesey, and mostly between the 10- 
and 20-fathom lines. 
3. The largest plaice of all migrate to the north-west 
towards the North-east Coast of Isle of Man, 
and are caught mainly on the Great Bank to the 
east of Bahama Light Vessel where the water is less 
than ten fathoms in depth.
