Such practice led to the invention of waradaia7ni which is a 

 kind cf pound net. It was about one hundred years ago that 

 improvements were introduced in these nets, by which, instead 

 of straw, hemp was used, and other arrangements were made 

 so as to retain the fish in the net. These nets existed side by 

 side with the zvaradaiami hut in 1889 with the invention of the 

 above mentioned pound net the jfishing proved so successful 

 and profitable that fishermen in various districts to a man followed 

 the example in adopting these nets. They are extensively used 

 in the sea of Japan. The Japanese coast fishing is chiefly done 

 in the autumn, winter, and spring. 



According to this method a net with an entrance 80 or 90 

 fathoms inside and 150 or 160 fathoms in depth is used. From

 •some 60 or 70 fishermen being employed in fishing. The nets 

 are hauled^up several times a day and the number of fishes 

 caught in one hauling is figured at some ten thousands.
