NOTES ON THE FISHES OF JAPAN.

the Salmon in the North-east. It spawns in May and June, 

 when it seeks the proximity of a wooded coast, and the young, 

 which differ in their elongated form and in other respects from 

 the adult, are stated to be seven or eight inches long in six 

 months after they are hatched. It would be important, how- 

 ever, to follow their development from the egg. It is captured 

 by hook and line, but also by an ingenious method with a decoy- 

 bush and raft constructed of bamboo. When the fishes congre- 

 gate under the raft they are caught by hooks baited with Squids. 

 Another method is to encircle by means of two boats the decoy- 

 bush and bamboos by a loop of a seine-net, whilst a third boat 

 by and by enters the circle and drives the Dolphins into the fish- 

 pocket by beating the surface of the water with sticks, and then 

 the circle is closed. The plan of using strong bare hooks beneath 

 the fishes and jerking them out of the water would seem to be 

 adapted for this fish when congregated under the decoy-bush and 

 raft of bamboos. 



The Plates in this fascicle are four in number and represent 

 eight species. Their execution would do credit to any country. 

 The artist, K. Ito, is to be congratulated on his work, and similar 

 commendation is merited by the lithographer, E. Koshiba.
