The Department of Aquaculture, National Penghu University had investigated biology in 13 intertidal zones where are located in Magong City, Husi Hsiang and Bai Sha Hsiang during 2004. Under intensive sampling, we took down 5 orders, 28 families, 48 genus and 67 species of fishes, 11 division, 83 families 117 genus and 173 species of invertebrates, 4 division, 28 families, 41 genus and 65 species of algae. For the reason to get more and deeper understanding about species in the intertidal zone, our department continued to conduct the survey of biodiversity. We had conducted our 193 sampling in the intertidal zones of Si-Wei and Wu-Kan of Magong City, He-Jie, Chih-Ma and Nei-An of Siyu Hsiang in the Penghu county from January to September, 2005. The results showed that we get 8 orders, 35 families, 74 genus and 108 species of fishes and the dominate Family was Gobiidae followed by the Blenniidae, among them. Also the results showed that there were 9 division, 76 families and 173 species of invertebrates and the Mollusca and Arthropoda were dominate Phylum. Also, 64 species of algae were found within 33 families which Rhodophyta was dominate Phylum followed by Phaeophyta. Investigations of intertidal zones were made in Niao-yu of Bai Sha Hsiang and Jiang-jun of Wan-an Hsiang from March to September, 2006. Meanwhile Nei-An of Siyu Hsiang was added into the sampling area from July. There were 6 orders, 24 families, 40 genus, and 62 species of fishes. Blenniidae was second to Pomacentridae. For invertebrate, there were 8 phylums, 55 families, and 97 genuses. Mollusca and Arthropoda were often found. There were 4 phylum, 35 families, 52 genus, and 73 species of algae. Rhodophyta dominated the most, and followed by Chlorophyta. According to the findings made in the past three years, the organism of intertidal zone was closely related to geography and seabed. The similarity among the species found in these sampling area was not abvious, which indicated that the biodiversity of the intertidal zones in Penghu. It provided an excellent habitat to balance the ecosystem. |
