MARINE FOOD FISHES 129 



season it is not unusual to search for the eggs of these 

 fish with a well-greased sound, for where the herring 

 spawn is, there the haddock are gathered together. 



It is worthy of note that when an exceptional catch 

 of haddock is made, if the stomachs of these fish are 

 examined they will frequently be found to be full of 

 herring spawn. 



The long line is usually left down during the night, 

 and weather permitting is fished the following day. In 

 rough weather, however, it may be impossible to take 

 it up for several days, and then as already stated, dog- 

 fish play havoc with the catch. 



Halibut, cod, haddock, skates and rays are the more 

 important of the marketable food fishes taken on the 

 long line. 



Of the various nets the trammel, the seine, the drift- 

 net, and the trawl are the only ones that call for our 

 attention. The trammel is not a single net, but consists 

 of three perpendicular walls of netting set in the sea 

 alongside each other, and at right angles to the shore. 

 Each wall of netting is corked above and weighted below. 

 The two outer walls of netting have a large mesh, whereas 

 the mesh of the centre net is quite small. Further, the 

 central net is twice the length of the two outer nets, but 

 is gathered together and set slack so as to hang between 

 them. The trammel catches fish as they swim along 

 the shore and is mainly used to procure such fish as 

 mullet and bass. A mullet coming, say, from the right, 

 swims through the broad meshes of the outer wall on
