These fishings includes five major fishies; tuna long line fishery, danish seine fishery, torch light net fishing, trawl net fishery and purse seine for mackarel fishery. Fishing data have been recorded from Taiwan fisheries year books on time series basis. The positions of fishing activities have been also recorded through VMS ( Vessel Monitoring System ). As a result, the resources exploitation are able to be fully evaluated. Analysis of the production value of each fishery in the overlapping area showed that the production value of tuna long line fishers are between $980 thousand and $12.3 million NT from 1998 to 2007. The production value of the danish seine fishery are between $10 million and $31.51 NT from 2003 to 2007. The production value of the torch lighe net fishery are between $5.02 million and $29.83 million NT in 1998 to 2007. The production value of trawl net fishery was $920 thousand NT in 2005. The production value of the purse seine for mackerel fishery was between $8.55 million and $235.91 million NT in 1982 to 2005.
