Diving fishermen are demanding permission to use an inspirator that can efficiently catch Manila clam; however,
coastal fishermenargue that the use of inspirator devastates the seabed and depletes fishery resources. Therefore, the
aim of this study was to evaluate the fishing power of diving gears and its effect on coastal fishing grounds. The average
time taken to fish in the seabed (4 m2) with a rake, water gun, and an inspirator was 11.17 min, 13.33 min and
7.81 min, respectivelyThe values of catch per unit time with a rake, water gun , and an inspirator were 3.35 kg/min,
2.26 kg/min, and 3.83 kg/min, respectively. Suspended sediments were observed the most in the water gun fishing
area, and were observed more in April when fishing was not carried out than in February when fishing was carried
out. However, the difference in the amount of sediment deposited in the fishing area using the three-fishing gears was
very small. For an accurate analysis of the impact of the fishing gears on the seabed, supplementary tests such as grain
size analysis and changes in benthic organisms need to be conducted.
