as in Luce Bay, for trawling by sailing vessels is permitted. 

 The shortest half -range is from 25 to 34 cms., and 65 per cent, 

 of all the fish caught were over 25 and under 39 cms. 



Beaumaris and Red Wharf Bays. 



This also is an inshore fishery, mostly inside the three- 

 miles' limit. The main season is in the late autumn — about 

 October to January. We shall show later that this autumn 

 fishery depends on a migration taking plaice from the regions 

 to the N.E. The fish are bigger than on the other grounds in 

 Liverpool Bay and off the Lancashire coasts, the half -range 

 being from 19 to 28 cms. 



Carnarvon Bay, Mersey Estuary, Liverpool Bar 

 to Blackpool, Morecambe Bay (inshore). 



All this area may be regarded as a single, natural one. 

 The fishery is carried on mainly by half-decked vessels, a few 

 smacks, and an occasional steam trawler. It is mostly inside 

 the three-miles' limit, though there is also a considerable area 

 of plaice-ground outside this contour. The main fishing season 

 is from about July to October. The whole ground may be 

 regarded as a typical small-plaice one. 



The characteristic lengths of the plaice caught in the 

 months August to October are : 



Carnarvon Bay 18 to 24 cms. 



Liverpool to Blackpool ... 18 to 22 cms. 



Mersey Estuary 20 to 24 cms. 



Morecambe Bay ... ... 20 to 25 cms. 



These are the shortest half-ranges, comprising 50 per cent, 

 of all the fish caught.
