TABLES. 



Showing Results of some Hauls ivith Experimental Fish Trawl Nets having different sized 

 meshes ; also Result of some Experimental Hauls on Blackpool Closed Grounds, Heysham 

 Lake, and elsei&liere ; destruction to Undersized Sea Fish caused by Shrimp A 7 cts, and 

 other matters. 



I. Trials with 6 and 7-inch meshes in Trawl Nets, showing the result with regard 



to the takes of Flukes. 



(i.) Six-inch mesh took 205 flukes under jib. \ One drag of i^ hours' 



Seven-inch mesh took 82 flukes under jib. duration. 



Two boats used in the trial, nets down same time, beam same length. 



(2.) Six-inch mesh took 66=5 flukes, 332 under ilb. } 



In four drags. 

 Seven-inch mesh took 457 flukes, 148 under jib. ) 



Nets down same time. Two boats were used in three of the hauls. 



(3.) In one drag of an hour's duration. Mesh of over seven inches took 15 score Ibs. of 

 fish, including 819 plaice, 57 of which were under jib. Six-inch mesh took 248 plaice, 92 of 

 which were under jib. same time and place. There was no weed or debris in the nets to 

 prevent the escape of fish. Our experience shows that the seven-inch mesh will take nearly all 

 soles of fib., flukes of Jib., and codling and haddock of lib., and accidentally many under 

 these weights. 



(4.) The result of a number of hauls, a copy of which is appended, was as follows : In 

 nine hauls with the six-inch mesh, the total time the net was down being 14 hours 25 minutes, 

 the takes amounted to 1,997 flukes, 932 being over jib. in weight each, and 1,065 under. 

 In eight hauls with seven-inch mesh, the total time the net was down being 12 hours 27 

 minutes, the result was 1,557 flukes, 1,269 being over jib. each and 288 under. 



Although the seven-inch mesh trawl was down i hour 58 minutes less time than the 

 six-inch, it took 337 more fish over jib. in weight, and of undersized fish it took 777 less.
