The sea around Taiwan is a hot spot for shipwreck. Once the heavy oil contained in a ship has leaked due to accident, it often affects the ecology of surrounding sea and fishermen's livelihoods. However, due to the lack of information on fisheries in inter-coastal fishing, there is no clear evidence of loss of fishery and no reasonable follow-up compensation. Therefore, how to establish the data of the fishing and fishing resources and assess the damage of the fishing industry should be one of the important tasks in tackling the oil pollution accidents in the future. This study conducted a basic survey of the coastal ecology of Jinshan District, New Taipei City to understand the ecological status of the coastal area. On the other hand, the fishery resources survey is carried out for the important harvested species in this area, and the basic data of fishery resources are established. These results can be used as the basis for claims for similar events in the future. This study shows that the resources of the main shore-harvesting species,Cellana toreuma , in the Jinshan District of New Taipei City vary seasonally and vary from place to place, but all are in the summer.
