Intertidal zone is the area between low tide and high tide, and which is largely influenced by physical and chemical factors. In addition, becauses of the rise of coastal construction and the tourism industries, the influence of human interference becomes more and more serious. Therefore, the research of the human interference effects on intertidal zone becomes more important in recent years. In northern Taiwan, there are several different type of intertidal pools which are diverse in the dissimilar geographic substrate and biological habitat. It shows high biological diversity and great potential of ecotourism. However, the natural fish fauna record have not been clearly reported in the previous studies.
In this thesis, we tried to demonstrate the resilience of different intertidal fish communities after a series of disturbances by different time interval including 1-3 days, 1-2 weeks, and 1 month. It was based on different types of substrate and different seasons. The types of substrate were algal reef, algal reef-gravel mix type, and rocky reef. We sampled in the northern Taiwan coast in summer, autumn and winter in 2011. Finally, Compare tidepool fish community in the long-term changes with the researches of 30 years ago. We collected 17,364 fishes (inculding 18 families and 57 species). We seperated these fishes into different groups according to different searches by habitat and trophic level. These results showed that Blenniidae is rare in algal reef, but dominant in rocky area. And Clinidae and Tripterygiidae only found in rocky area. Asterropteryx semipunctata only found in algal reef. The resident species showed higher proportion of the total weight, the number of species and the number of individuals in every sample collections, which were similar to previous studies in the temperate intertidal zone. And the omnivores dominant in algal reef and mixed area were largely affected by seasonal change. In the part of resilience, the number of families and species, relative abundance and several diversity index showed the time interval of 2 weeks or a month are returned to the first sample (I), and the ANOSIM of the simple matching coefficient shows no clustering situation in every series of samples, which means the species composition have no difference. But the ANOSIM of the Bray-Curtis Similarity at mixed area, summer, and algal reef, summer and winter, has clustering with different time interval which following the sampling order. After the SIMPER analysis, we could found the relative abundance of the major different species changed with the date of sampling. These results may indicate that the intertidal fish community does not affected by sampling interference but by seasonal change.
Compared with the researches of 30 years ago in rocky pools from Taiwan. The number of family descend from nearly 40 to 15 families, and the number of species from over hundred to 32. The dominant from the semi-resident become the resident, and from the omnivores and omnivores become the omnivores. Thus, the conservation of intertidal zone really need to be paid attention in Taiwan.
