KEPORT OF THE COUNCIL. 101 



112; and her employment on North Sea fishery researcli havmg now 

 terminated, the total number of hauls made from her decks in connection 

 with this work in the North Sea may be stated. It is as follows : — 



Commercial Gear: Otter trawl, 569; Beam trawl, 920. Total, 1489 



hauls. 

 Small Gear: Shrimp trawl, 134; Agassiz trawl, 173; Todd's trawl, 



47 ; Dredge, 177 ; Conical dredge, 599 ; D-net, 8 ; Oyster 



dredge, 3 ; Petersen's Young-fish trawl, 113. 



Hensen net, 65 ; Brood nets, 40 ; Garstang net, 34 ; other 



tow-nets, 120. Total, 1513 hauls. 



Tlie total number of stations at which small gear has been used is 

 1337, but as on many occasions more than one net was used at a 

 station, the number of hauls is higher, reaching, as shown above, 1513. 

 In addition to the operations of the Huxley in the open sea, data have 

 been collected from time to time, as has been stated in previous reports, 

 concerning the shallower coastal waters. With the co-operation of the 

 Eastern Sea Fisheries District Committee in the Wash, and by the 

 employment of the Association's steamer Oithona in Bridlington Bay, 

 in the Suffolk bays and estuaries, and in the Thames, it has been 

 possible to collect valuable information concerning all of the more 

 important English inshore areas, that concerning the Wash being the 

 most extensive. Sixty-four hauls of the small Otter trawl were made 

 from the Oithona, while the use of the Shrimp trawl, shore nets. Conical 

 dredge, and other gear brings the total number of hauls from this 

 vessel in the North Sea up to 102. 



Fish Measuked. — As in former years, the total catch of fish was 

 again measured this year on nearly all occasions : owing to the devotion 

 of a considerable time to the collection of fish eggs and larvi\3, the 

 number measured is, however, somewhat less than during 1908-9. 

 The details as to the number of plaice, haddock, and other species 

 dealt with are as follows : — 



179,763 50,658 379,718 610,139 



Marking Experiments. — During the investigations 16,104 plaice, 

 together with 713 soles and 552 other fish, have been marked and 

 liberated by the Association, Of these, 4605 plaice (28 per cent), 

 57 soles (8 per cent), and 113 (20 per cent) other fish have been 

 recovered.
