Grey Snapper

• It gathers to spawn at particular points on the reef following the lunar cycle, which makes those aggregations easy to find and highly vulnerable to overfishing.
• It is one of the fish that best demonstrate the value of mangroves: reefs with mangrove nearby hold far larger snapper populations.
• It tolerates fresh water and can move tens of kilometres up rivers.
• Its life cycle depends on the mangrove. The juveniles grow up among the submerged roots, and isotope studies have shown that reefs neighbouring well-preserved mangroves hold much larger snapper populations.
• It is cautious and distrustful, which has given it a reputation among anglers for being hard to fool: it refuses baits and rigs that other snappers accept.
• It forms spawning aggregations at specific points in the lunar cycle, a behaviour that makes it very vulnerable if those aggregations are fished.
• It can live close to thirty years, a long time for a medium-sized snapper.
• Its colour varies from grey to reddish brown depending on the bottom and the state of the animal, and juveniles bear a dark band crossing the eye.
