GBR - Green zone contribution to the larval recruitment of three fish species in blue zones, 2007 - 2008 (MTSRF 4.8.1, JCU)

As part of MTSRF Project 4.8.1, this study aimed to assess the benefit of no-take (green) zones as a recruitment source. 1342 adult stripey snapper (Lutjanus carponotatus) from 3 green zones around the Keppel Islands were fin-clipped for genetic analysis and released. Microsatellite markers were used to assign juveniles to one or both parents. From the 483 juveniles collected from 16 sites in both green and blue zones, 140 (~30%) were assigned to one or both parents from the adult sample. Of the 140 juveniles, 16% had recruited into home green zones, 62% had dispersed into blue zones, and the remainder had dispersed among other green zones.

本研究作为MTSRF项目4.8.1的组成部分，旨在评估禁捕（绿色）保护区作为鱼类种群补充源的效益。研究人员通过剪鳍方式，从凯珀尔群岛周边3个绿色保护区内采集1342尾成年条纹笛鲷（Lutjanus carponotatus）的鳍组织用于遗传分析后，将其放归原生海域。本研究采用微卫星标记（Microsatellite markers）技术开展亲权鉴定，将采集到的幼鱼归属至单个亲本或双亲亲本。从绿色保护区与蓝色区域共16个采样点获取的483尾幼鱼中，有140尾（约占30%）可被归属至本次成年采样样本中的单个亲本或双亲亲本。在这140尾可归属的幼鱼中，16%补充至其原生绿色保护区，62%扩散至蓝色区域，剩余个体则扩散至其他绿色保护区。
