Pi byen konprann dinamik yo epapiye nan lav pwason, Ostralyen Rechèch Konsèy la (ARC) ak konsèrvasyon a Nature (TNC) fè yon analiz jenetik ki mezire epapiye larva ki sòti nan yon sèl pwason reproduksion agrégation (FSA) nan squaretail coralgrouperPlectropomus areolatus) nan Manus, Papua New Guinea. Nan 2004, ranplir aksyon pwason lokal yo, pechè ki nan yon sèl zòn CMT etabli yon zòn marin pwoteje (MPA) pwoteje 13% nan lakou lapèch yo, ki gen ladan etid la FSA. Chèchè yo ak pechè lokal yo echantiyon sa a FSA sou 2 semèn nan mwa me 2010 ak kolekte echantiyon tisi ki soti nan, ak ekstèn atenn, 416 coralgroupers granmoun, ki reprezante yon 43% estime nan popilasyon an FSA.

To better understand the dispersal dynamics of fish larvae, The Australian Research Council (ARC) and The Nature Conservancy (TNC) conducted a genetic analysis to measure larval dispersal from a single fish spawning aggregation (FSA) of squaretail coralgrouper (Plectropomus areolatus) at Manus, Papua New Guinea. In 2004, to replenish local fish stocks, fishers within a single CMT area established a marine protected area (MPA) protecting 13% of their fishing grounds, including the studied FSA. Researchers and local fishers sampled this FSA over 2 weeks in May 2010 and collected tissue samples from, and externally tagged, 416 adult coralgroupers, which represented an estimated 43% of the FSA population.
