Besides these there are still many other species of shrimps and 
lobsters in Japan. They are all used for food or bait, and are 
economically very important. Palinurus Japonicus, or the Spiny 
Lobster, lives on stony bottoms of the Pacific shores washed by 
warm currents; but the other species are mostly found in bays, 
and prefer sandy or muddy bottoms. They usually hide them- 
selves during the day, and go out in search of food at night.

APPARATUS FOR FISHING FOR SHRIMPS AND 
LOBSTERS. 
The Spiny Lobster is caught with gill-nets, while the other 
smaller forms are caught either with trawls or flat-nets, or with 
traps. 
No. 291. Lobster-trawl. 35. 
This is a hempen net extensively used in the Inland Sea, and 
~ closely resembles the trawl for catching soles already described. 
The only points of difference are the comparative lightness of the 
weight used, and the stem of bamboo used for keeping the mouth 
of the trawl open. The former circumstance is due to the fact that 
this trawl is used on muddy bottoms. The purse is about fourteen 
feet long, and the wings are about eighteen feet in length. The 
meshes are a little less than half an inch in the posterior part of the 
purse, and from half an inch to a little over five-eighths of an inch 
in the remaining portion. The drag rope is from three hundred to 
four hundred feet long. This trawl is worked under a good wind, 
and two or three are usually attached to a single boat containing 
two men. 
No. 292. Lobster Gill-net. One Netting. 
This is a hempen net sunk to the bottom for catching the Spiny 
Lobster. It is about thirty-five feet long and only about three feet 
wide, and is therefore band-shaped. The meshes are one or two 
inches. A single boat usually carries two men, and uses several 
dozens of nettings joined into a single net to one end of which is 
then tied a stone and a float. The whole is then sunk in the 
evening in rocky places ten to fifty feet deep, and taken out the 
next morning.
