By permission of the Fishery Board for Scotland the 
Lancashire and Western Sea Fisheries Committee’s 
steamer was enabled to make a series of hauls with a 
trawl-net in the preserved waters of Luce Bay, on October 
26th, 1905. The primary object of these trawling opera- 
tions was to obtain a stock of mature living plaice for the 
Committee’s Sea-Fish Hatchery at Piel. Advantage was 
taken, however, of the opportunity thus afforded to com- 
pare the results usually obtained by fishing on the plaice 
grounds within*the Lancashire and Western Sea Fisheries 
area, Where trawling is permitted under certain restric- 
tions, with those obtainable by fishing in waters strictly 
preserved against all forms of trawling. In order 
to obtain the fish in as healthy a condition as possible a 
series of short hauls were made with a rather small trawl- 
net of 50 feet beam, and with 7 inch meshes throughout. 
By using such a net a very hmited number of inverte- 
brates were captured, and few small fish were obtained. 
\— 
The smallest plaice obtained in any of the hauls was 8:
