Pacific goliath grouper
|Pacific goliath grouper|
The Pacific goliath grouper is found primarily in shallow tropical waters among coral and artificial reefs at depths down to 165 ft (50 m). Their range includes the East Pacific from the Gulf of California to Peru.
Young groupers may live in brackish estuaries and canals.
They may reach extremely large sizes, growing to lengths of 8.2 ft (2.5 m) and can weigh as much as 800 lb (363 kg). They are usually around 400 lb when mature. Goliath groupers' inquisitive and generally fearless nature makes them relatively easy prey for spear fishermen. They also tend to spawn in large aggregations, returning consistently to the same locations, making them particularly vulnerable to mass harvesting.
Goliath groupers are believed to be protogynous hermaphrodites, with individuals first maturing as females, and only some large adults becoming males. Most groupers follow this pattern, but it has not yet been verified for the goliath. In fact, Bullock et al. found that males could be sexually mature at smaller sizes (around 1150 mm) and younger ages (4–6 years) than females ( around 1225 mm and 6–8 years).
