ground associated with the Plaice during August. The 
catch was taken by a shrimp trawl] the length of the mouth 
of which was 25 feet and with a mesh of § inch side. It 
was dragged for one hour over two miles of ground in six 
fathoms of water. The bottom was a mixture of sand and 
mud; the contents of the net were— 
Soles, 257; 11 were over 8 inches long, 4 of the catch 
were 2-8”, the remainder 2”. 
Plaice, ae ; 6 were over 8”, remainder 2/-8’. 
Dabs, 896; 2 were over 8”, remainder 2”-4”. 
Skates, 18; 7” broad across pectoral fins. 
Whiting, 285; 5” long. 
Shrimps, 20 quarts (a quart contains from 200 to 400 
animals). 
In addition to these about 200 Solenettes were caught, 
many other fishes (Z'rachinus, Ammodytes, Clupea 
sprattus) and a great number of Crabs. 
On the Blackpool Closed Grounds in the central part 
of the Lancashire shores even larger catches of young 
Plaice have been made. Thus in 4 drags with a shrimp 
trawl on—

Over 10,000 young Plaice, of 2”-4” mostly, being caught in

In the various nurseries the fauna associated with the 
Plaice varies somewhat, but in all shrimps are always 
found where young Plaice and other Pleuronectids occur. 
With increasing size the immature Plaice move out 
from the nurseries into deeper water. ‘This off-shore 
migration has been studied in an ingenious way by
