profitable at the time* In addition to these commercial purposes the 
wireless was also used to keep every trawler at sea fully informed of 
weather changes* 
The trawlers were away 12 - 14 days each voyage; of these, 4-6 
days were required in going to and returning from the grounds, some of 
which were more than 800 miles distant. Thus 8-10 days on the average 
were spent in actual work each trip. Each trawler made about 35-40 
hauls during each voyage, one haul taking 5 - 5J- hours. Upon their 
return to port, the trawlers did not normally lay over more than 24 hours 
« ^ 
so that apart from the time necessary for periodic repair and overhaul¬ 
ing (about one month per year) each trawler made about 20 - 24 voyages 
per year, 
fish caught by the company's fleet was landed at Shimonoseki, 
Hakata and Nagasaki, but the largest amounts were brought to Shimono¬ 
seki 36/ which had the best facilities for the quick transportation to 
the large urban fish consuming centers. 
Bottom dragging. These operations carried on by 
smaller vessels of 20 to 100 tons had a more restricted cruising radius. 
They used hand-reel nets which in most cases were drawn by two vessels 
working together* 
There appears to have been 1,800 - 2,000 such vessels in operation 
in recent years although one source reports more than 3,000 in 1931* 
36/ According to one source 56 vessels made Shimonoseki their head¬ 
quarters in a recent year while 8 worked from Na ga s aki and 6 from 
Bakata.
