Humphead Wraasse,被称为拿破仑鱼(Cheilinus Undulatulatulatulatul),是Labridae的最大生活成员。它缓慢增长,但可以增长到超过2米和190公斤的最大尺寸。该物种是第一批商业重要的珊瑚礁食品,该鱼类是在2004年濒危野生动物群和植物群(CITES)附录二的国际贸易公约中所列的珊瑚礁食品,因为其脆弱的地位和持续的国际贸易持续威胁。就像许多珊瑚礁鱼一样,汉普朗克拉斯,Cheefus undulatus,在礁石地区聚集在礁石地区,这种产卵行为使它们变得非常容易受到过度捕捞。评估本物种的产卵聚合在菲律宾塔瓦塔维省的锡伯特和西洋凯的市内进行。作出了与渔民,养殖家和其他利益攸关方和焦点集团讨论(FGD)的主要线人访谈(KII)进行了当地政府领导,渔业和水生管理(农场),养殖师,养殖师和出口商。由这些KII和FGDS的结果为指导,Mameng的水下视觉人口普查(拿破仑濑鱼的当地公共名称)群体(少年和成熟)进行了文献产卵聚合网站。由于珊瑚礁地区Mameng的实际产卵聚集没有照片文件,因此使用了间接措施。KII和FGD的结果表明,SIPANGKOT和TANDO OWAK的Baligtang Reef是产卵的主要来源。Bajau渔民的轶事账户表明,Dungun Dungon,Baligtang Runef,Baligtang Runef,Tando Owak和Tugalan是Mameng产卵聚集的传统渔场。 From the length-frequency analysis of mameng caught by hook and line and fish pot in the Baligtang Reef in Sipangkot, the estimated length at maturity of this species was found to be 25-35 cm. There were 134 individuals caught within this size range so they are considered potential spawners. Another indirect proof used was the underwater documentation of juvenile humphead wrasse which were regularly observed and photographed in association with seagrass beds and branching coral reefs in Baligtang Reef in Sipangkot, Sitangkai. Gonadal study also indicated that the mameng caught in this area had mature and ripe gonads but the number of mature fish depends on the season. These were the basis of declaring Spawning Aggregation Sites in Tando Owak and Dungun Dungun in Sibutu and Baligtang Reef, Sipangkot and Tugalan in Sitangkai. These were declared as marine protected areas by ordinance of the municipal Sangguniang Bayan of the two municipalities. Management and enforcement plans have been developed and Bantay Dagat have been trained to protect the spawning aggregations and this strategy aims to protect the wild stocks of humphead wrasse. Protecting the spawners would ensure that there would be enough recruits, prevent recruitment overfishing and enhance the wild stocks.
