SEA-FISHERIES LABORATORY. 259 



which inhabit this area migrate round Anglesey to the 

 southern part of St. George's Channel, while others go to 

 the North towards the Bahama Bank area. What is the 

 proportion of fish taking part in these movements has 

 still to be ascertained by further experiments and the 

 collating of all the results. 



In the tables which follow we have arranged the data 

 just as in former years. In addition to the particulars 

 published, the sex, weight, age, and phase of maturity 

 of the fishes returned have been determined, and are 

 recorded on the cards giving the history of each particular 

 fish. These data have hardly at all been considered so 

 far : obviously some general ideas as to the possible use 

 of the material must be attained before the labour of a 

 detailed analysis of all the data is undertaken. 



The methods of recapture of the fishes are given in 

 the last column : — -" 8N ;; means stake-net, " IT," first-class 

 trawler, " 2T," second-class trawler, " ST," steam 

 trawler, " GrN " and " FN," mean gill-net and flounder- 

 net, methods of fishing practised in Luce Bay. A few 

 recaptures denoted by "PC" were made by the Fleet- 

 wood Police Cutter trawling in Barrow Channel. This 

 year, for the first time, the S.S. "James Fletcher" 

 recaptured a plaice which had originally been liberated 

 from that vessel.
