The formation of Penghu http://s1.djyimg.com/i6/602101048441539.jpg
The basalt based structure • Provide the best substratum for coral to settle.
Tropic of cancer South China Sea surface current
Category of coral reef environment Coral reefs Coral community 戴昌鳳台灣珊瑚礁地圖
The distribution of coral in Penghu • Northern sea: • Inner sea: • Southern sea:
Northern sea • Hard coral: 111 species, 36 genera • Soft coral: 14 species, 7 genera • Due to the low SST during winter, formed only coral community.
Inner sea • Massive and encrusting coral dominate, scatter distribution due to high turbidity.
Southern Sea • Coral community similar to southern Taiwan, well-develop coral reefs. Hard coral dominate reef habitat. 戴昌鳳台灣珊瑚礁地圖

Coral reef related studies in Penghu • General survey • Corals and reef fishes community study • Mass death of reef organisms in 2008 • The effects of cage farming on benthic community • Maine protected area in Chin-wan inner bay
General survey 1992-1993
Fish and coral community studies • Shao et al. 1999, Chen et al. 1999, Hsieh 2008 and Liu et al. 2010

Maine protected area in Chin-wan inner bay Coral coverage drop down from 80% (2001) to 16% (2008). The lost of fish and invertebrate functional group before 2001, out break of corallivorous and anthropogenic impact are the reason coral coverage keep declining, even the no-take zone established in 2005.
