It will te noticed that the nature of the fishing implement and the duration of 

 fishing operations are given in every case — facts which must he taken into considera- 

 tion when comparing the catches at different stations. The size of the beam chiefly 

 used on hoard the "Fingal" was 25 feet ; but the trawl nets used were of different 

 kinds. "When the kind of net is not specified, it is to be understood that a net of ordi- 

 nary construction and mesh was used. The net indicated as " Patent " was a " Comyn's 

 Patent discriminating trawl " net, supplied for a 25-foot beam, but towards the end of 

 the cruise fitted on one somewhat larger. An endeavour will he made in Part XXIX. 

 to compare the results obtained with this trawl with those obtained by the use of 

 an ordinary net. On board the " Harlequin" a beam of 48 feet, with a net of 

 ordinary construction and mesh, was almost invariably used, except in deep-sea 

 fishing. As regards the Long lines full explanation as to the number of hooks and 

 kind of bait employed will be found in the last section of this Report. 



In discriminating between mature and immature fish, the following limits of size 

 (in inches) have been used. The limit is intended to represent the minimum size of 

 mature fish, and is explained in Part XXIX. (p. 418) : —
