How and where it feeds
- Water temperature
- Feeds from 62°F to 91°F, best between 74°F and 86°F.
- Water depth
- 3 to 180 ft of water.
- Structure
- Mangrove, bridge, reef, jetty, ledge, channel, wreck and pier, in that order of preference.
- Tide and current
- Prefers moving water, with moderate current.Inshore fish feed along mangrove edges, bridge pilings and channel drop-offs while the tide runs, and the bite slows at slack. On offshore reefs a light current carries chum and pulls fish up off the bottom.
- Light
- Bites best around dawn and dusk; feeds at night too.
- Pressure
- Little response to pressure changes.
- Wind and sea limits
- 18 kt of wind and 4 ft of sea. The Waterlands engine scores hours down as conditions pass them.
Tackle and technique
Mangrove snapper hold tight to mangrove roots, bridge pilings, jetties and reef ledges, from a few feet deep inshore to 150 feet offshore. Chum to pull them out of cover, then freeline or lightly weight a live shrimp or pilchard on fluorocarbon leader, since they shy away from heavy line in clear water. The bite improves at dusk and after dark.
- Methods
- bottom fishing, chumming, freelining, light jigging
- Lures
- small bucktail jigs, jig heads tipped with shrimp
- Bait
- live shrimp, pilchards, cut ballyhoo, squid, pinfish, fiddler crabs
