海葵和它们的宿主海葵在珊瑚礁环境中形成了标志性的共生关系，在海洋水族馆贸易中受到高度追捧。这项研究考察了无性繁殖作为一种培养地理上广泛分布和常见交易的寄主海葵--四色海葵的方法。他们做了两个实验：第一个是确定切割成两半或四分之一后，大小或颜色的变化是否会影响存活；第二个是确定切割后是否需要喂食来最大化存活和生长。两个实验的存活率都很高，分别有89.3%和93.8%的海葵被砍成两半，62.5%和80.4%的海葵在实验1和实验2中存活。切成两半的海葵比切成四分的海葵体型更大，愈合和生长更快。然而，尽管当个体被切成四分时存活率较低，但这种处理产生了最多数量的海葵。喂食增加了口盘直径的增长，减少了湿重损失，但对脚盘直径没有显著影响。考虑到海葵需要56天才能形成偏离中心的嘴，如果实验进行得更长，喂食很可能会产生更大的效果。这种低技术的繁殖方法可以用来全年繁殖个体，然后海葵可以用来供应水族馆贸易或补充枯竭的栖息地，从而支持珊瑚礁地区的生物多样性保护。
Anemonefishes and their host sea anemones form an iconic symbiotic association in reef environments, and are highly sought after in the marine aquarium trade. This study examines asexual propagation as a method for culturing a geographically widespread and commonly traded species of host sea anemone, Entacmaea quadricolor. Two experiments were done: the first to establish whether size or colour morph influenced survival after cutting into halves or quarters; and the second to see whether feeding was needed to maximise survival and growth after cutting. Survival rates were high in both experiments, with 89.3 and 93.8% of the anemones cut in half, and 62.5 and 80.4% cut in quarters surviving in experiments 1 and 2, respectively. Anemones that were cut in half were larger in size, and healed and grew quicker than those cut in quarters. However, even though survival was lower when the individuals were cut in quarters, this treatment produced the greatest number of anemones. Feeding increased oral disc diameter growth and reduced wet weight loss, but did not significantly influence pedal disc diameter. Given that the anemones took up to 56 d to form an off-centre mouth, it is highly likely that feeding may have produced greater effect if the experiment was run for longer. This low technology method of propagation could be used to produce individuals throughout the year and the anemones could then be used to supply the aquarium trade or restock depleted habitats, thus supporting biodiversity conservation in coral reef areas.
