Greater Amberjack sea surface temperature guide.
Greater amberjack are the iconic deep-structure fight fish — wrecks, rigs, and ledges from the Carolinas through the Gulf. SST is less predictive for AJ than for pelagics; bottom structure is the key locator.
SST threshold gauge
The water temperature ranges that determine where greater amberjack hold and feed. Hard thresholds (dashed lines) are values outside which fish actively depart or become inactive.
Depth profile & SST reliability
Amberjack hold over deep structure and respond to current edges. Surface SST is a weaker signal than for pelagics.
Current systems & structure
Amberjack key on bait pushed onto wrecks and rigs by current. Spring and fall current breaks concentrate fish.

Conservation & regulations
Overfished (Gulf) — under recovery plan. Closed seasons during spawning periods. Tight bag and size limits. Verify current rule before harvest.
Stock assessment source →Drop big jigs and live blue runners to wrecks, rigs, and reefs. Amberjack are aggressive — they'll hit anything that looks alive. Target current-facing edges of structure.
