Western Atlantic Sea Bream
Archosargus rhomboidalis
A small, tough little porgy of lagoons, mangrove swamps and grass flats — more an inshore fish than a reef fish. It tolerates brackish water and is a regular catch around docks and grass beds.

Where they live
How to catch them
Mangrove and lagoon fishing Shore
Rig: Light spinning rod, small split shot and a #1 hook under a small float or free-lined
Bait/lure: Live or dead shrimp
Key tip: Cast tight to mangrove roots and dock shade at moving tide; juveniles shelter there and adults patrol the edges.
Shore and pier bottom fishing Shore
Rig: Two-hook dropper rig with a pyramid sinker, #2-1/0 hooks
Bait/lure: Shrimp pieces or clam
Key tip: Cast to sandy holes beside rock, dock or mangrove structure and watch for light, nibbling bites.
Best baits & lures
Baseline setup
- Rod: Light to medium spinning rod 2.1-2.4 m
- Line: 10-20 lb braid or mono main line
- Terminal: 20-30 lb fluorocarbon leader, #2-1/0 circle hooks, egg or pyramid sinkers to hold bottom
Recommended gear for this species
Rod · Best value
7'6" medium-heavy jigging rod
≈ US$110-170
Works 2-6 oz jigs over rock and reef and still has the backbone to lift a halibut off the bottom.
Line · Budget
50 lb braid with 40 lb leader (200 yd)
≈ US$25-40
Thin braid cuts the current so jigs stay vertical; the leader shrugs off rock and teeth.
Terminal · Budget
Leadhead jigs, swimbaits and two-hook bottom rigs
≈ US$25-40
A leadhead with a swimbait tail is the universal bottom-fish catcher, from rockfish to cod to flounder.
