Effective removal of Acanthasterplanci at four islands in the south of Penghu

The removal of Acanthasterplanci in the sea areasurrounding Xiji Island has entered the 4th consecutive year, andthe number of Acanthasterplanci removed has increased sequentially each year. The removal operation in 2013 took place before the breeding period of Acanthasterplanci; after dissecting the Acanthasterplanci that were removed, their reproductive glands were all very full; the populationwas unevenly distributed because they began gathering to reproduce and somehave begun pairing. No Acanthasterplanci were found in the same sea area in 2014 and the cause is still being monitored. Yet, the local coral ecology has apparently recovered and ecological balance inthe sea area has improved, which is a gratifying result.
