博士 / 國立高雄科技大學 / 水圈學院水產科技產業博士班 / 107 / This study take the Hsinchu Mingfa set net for the eight operation years from 2000 to 2007. The data analysis before and after the installation of the bottom net was set up, and the key factors for the successful establishment of the network were added. The results of the study are summarized as follows:
1.The water depth of the sea is between 14 meters and 24 meters, the slope is gentle, and there is a "fishway".
2.The bottom of the seabed is black sand and muddy mixed substrate.
3.The tidal flow is mainly south-southwest (SSW) and north-north-east (NNE); the flow rate is between 10 and 30cm/s (0.2 to 0.6 knots), which is suitable for fishing operations.
4.During the fishing operation, the average water temperature is between 18 and 25 degrees Celsius, and the rapid rise and fall is small; the salinity is between 30 and 35 psu; the average temperature is between 15 and 28 degrees Celsius, and the rapid rise and fall is small; the average pressure is between 1004 To 1010 hectopascals (hPa), the pressure gradient is larger during the typhoon; the precipitation is between 38 and 232 mm, and the precipitation stability is acceptable.
5.The average wind speed during fishing operations is 2 to 3.8 m/sec, but the wind speed is increased in the northeast monsoon, low-pressure cyclone or typhoon; the average wave height is 0.6 to 1.30 m, although it has an impact on fishing operations, it is still allowed. range.
6.There will be typhoon passing through the sea area. If you do not pay attention to the typhoon news, it is easy to cause damage; the tidal range of the fishing place in Haishan Fishing Port is large, forming a waiting port, and the fishing time is limited.
7.Local fish species and production, after cost comparison and efficiency comparison, are in line with economic benefits.
