Nets-experiments 
Table I. General Table: 1904—1905 
Country ieee Apparatus employed Purpose of the Experiments 
Gill-nets with meshes To determine the relative abun- 
‘ 102 of different sizes, and | dance of the plaice (P. platessa) and 
Sweden ground-lines with | other species on different kinds of 
hooks of different sizes | bottom-soil, as mud, sand, stones etc. 
To investigate the results of fishing 
Holland 13 otter-trawl with and without extra weights on’ 
the ground-rope. 
To determine the relative quanti- 
ties of the different sizes of fishes 
Belgium 50 small beam-trawl which escape through the meshes of 
the cod-end in trawls with small 
meshes. 
To delermine the relative quanti- 
ties of the different sizes of fishes 
England 13 large beam-trawl which escape through the meshes 
of the different parts of the net; 
square, batings ete.
