The tunny moves in large shoals in the Kuro-Shiwo but never 
enters bays or inland seas. It is carnivorous and feeds on small 
fishes and squids, being often seen dancing around shoals of small 
fish and eating them. It is very quick in its movements and is a 
good swimmer. Specimens 5 feet long and weighing more than 
one hundred and twenty-four pounds are quite common. The 
tunny is caught throughout the year, but summer is the best fish-

top of which some easily observable signals are placed. The 
principal cord does not reach the bottom of the sea, but is kept 
suspended at some intermediate depth. For bait squids and horse- 
mackerel are used.
