This video from Australia says about itself:
Coral trout, Plectropomus leopardus, gather to spawn at dusk around the new moon in spring and early summer at Lizard Island on the northern Great Barrier Reef. Substantial research into the biology and ecology of this highly sought-after table fish has been conducted at the Australian Museum‘s Lizard Island Research Station.

No-fishing scheme in Great Barrier Reef succeeds with valuable fishes
Coral trout thrive but protection has less effect on other reef residents

An ambitious, hotly debated system of no-take reserves inside the Great Barrier Reef Marine Park has boosted the population of its most commercially valuable fishes, says the first 10-year progress report.
Coral trout (Plectropomus species) are now more common and bigger in protected spots than in comparable places still being fished, researchers say online March 26 in Current Biology. The no-take zones also gave these fish populations more resilience, with ample coral trout that had grown large enough to survive when severe tropical cyclone Hamish hit in 2009.
