Line Fish
抄録
Fishing is classified into net fishing, line fishing and miscellaneous fishing. Of the different types of net fishing, there are many which are operated on a large scale, such as trawl net fishing, purse seine fishing, gill net fishing for salmon, etc. Line fishing is mostly operated on a small scale in coastal waters; the exceptions are tuna longline and skipjack pole-and-line fishing. This may be one of the reasons for there being relatively few studies on line fisheries.
