A STUDY ON TROUT AND YOUNG SALMON. 301 



ordinary kind are also employed. These seines, the dimension 

 and mesh of which are very varying in different parts of the 

 country, very rarely possess a mesh as small as the ordinary 

 mesh of herring seines, 15 — 20 knots pr. foot (Norvv.). When 

 a small mesh is used, the points of the seine as a rule are of 

 a large mesh, the small mesh only occupying a short stretch 

 in the middle of the seine. 



A description of the groundseines commonly used in the 

 Trondhjem fiord will be found in my paper on the fishing with 

 groudseines in the Beitstadfiord in „Aarsberehiing vedk. Norges 

 Fiskerier". 3. 1900. These seines must be regarded as t5^es 

 of the seine gear, commonly used in this part of the country, 

 and which may come into use in fishing for saltwater fish in 

 a river mouth. 



More cursory examination of the seine gear of other 

 districts has convinced me that the majority of such gear, which 

 might be used for such fishing as above mentioned, does not, 

 as regards the mesh, differ to any important extent from the 

 above mentioned seines. 



Finally, respecting the employment of finemeshed eeltraps, 

 I may remark that the use of such gear in river mouths is in 

 most parts of our country, unknown. As such fishing gear may 

 be employed with advantage only during autumn, when our 

 river mouths are devoid of emigrating young salmon, a prohi- 

 bition against their use will only put obstacles in the way of 

 the fishing indushy without furthering the object in view viz: 

 the protection of young salmon. 



That fishermen with the intention of fishing for young salmon, 

 would procure gear of such a fine mesh as those seines which 

 I have specially provided and employed for my fishing experi- 

 ments, is out of the question. And even with gear of such 

 small mesh and such fishing power, only a relatively small 

 number of young salmon are caught.
