Diversity Of Coral Species Along The Yunlong Bay,Wenchang City And Artifical Breeding Of Amphiprion Ocellaris

The species diversity of corals in the Yunlong bay Coastal waters, Longlou town, Wenchang city, Hainan Province were surveyed by taking photos and making videos from may,2010. According to the results of the investigation,24scleractinian coral species in17genera among10families were recorded. The dominant genera were Acropora, Montipora and Favites and the most common species were Acropora digitifera, Montipora foliosa, and Pavona decussata. The number of scleractinian corals in Yunlong bay is less than that in Luhuitou of Sanya and Hong Kong, accord the trend that the distribution of scleractinian corals gradual elimination from south to north. The number is also less than that in Changjiang of Hainan Province, Weizhou Island of Guangxi Province and Xuwen of Guangdong Province. This may be caused by the resource destruction and survey omissions. It is predicted that more species will be identified in future investigations.The coral-reef fish plays an important rule of the coral-reef ecosystems. To develop artificial releasing of coral-reef fish has great significance in coral-reef protecting and repairing. In order to understand the condition in pairing, breading and growing of amphiprion ocellaris, using the method of experimental biology to keep the brood stocks, eggs and fry. Depends on research, the eggs of amphiprion ocellaris are tackiness, the clownfish lay500-1000eggs each time and they all stick to the net, the male protects the net. The fertilized eggs are oval and orange when spawned, after3nights, they will turn to green. The eggs take8days to hatch and the temperature of the water should at28℃. The fry can only eat Chlorella and rotifer when they incubation, While in7～14days, the fish start to grow stripes and able to eat copepods and powder feed.
