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.
