为了探讨珊瑚人工养殖的基本条件和方法,分别在陆基水泥池中和海底珊瑚苗床上对3种鹿角珊瑚:粗野鹿角珊瑚(Acroporahumilis)、霜鹿角珊瑚(Acroporapruinosa)和松枝鹿角珊瑚(Acroporabrueggemanni)的人工养殖进行了实验。结果表明,这3种珊瑚可以在深圳市鹅公湾近岸海域的海底珊瑚苗床上常年生长;在水泥池中当水温低于14℃或高于28℃时珊瑚陆续死亡;这3种珊瑚的生长速度在适温范围内随着水温的升高而加快,最大月生长值是6.05mm;光照对这3种珊瑚的生长有影响,直接的阳光照射会引起水泥池中珊瑚的死亡。
With the aim of gaining a better understanding of the basic condition and useful techniques for the cul-ture of zooxanthellate scleractinian corals,especially Acroporidae,three species of corals,Acropora humilis,Acro-pora pruinosa and Acropora brueggemanni have been maintained and growth respectively in tanks and on the coral planting shelves which sited in seabed in Ergong Bay,Shenzhen,China.The corals grew well anniversarily on the planting shelves in the sea,but could not live unless the temperature was between 14℃ and 28℃ in the tanks.The growth rate was increased with increased water temperature between 14℃ and 28℃,and the peak value of growth was 6.05 mm per month.Light plays an important role in the growth of zooxanthellate corals,but direct insolation killed all of the corals in tanks.
