Mangrove Jack

Mangrove Jack

Common Name: Mangrove Jack
Scientific Name: Lutjanus argentimaculatus
Maximum Size: 120cm
NSW Record: 11.68kg
Range: QLD, NSW, NT, WA.

The Mangrove Jack is often found in estuaries, particularly as a juvenile. Adult fish can be found on rocky and coral reefs, to depths of over 100m. Mangrove Jack will usually have a home cave within their territory, and a good cave system may hold multiple fish.

This species is generally of a greyish colour underwater, unless spotted in the shallows where the red colouration will show. The white-grey line underneath the eye is a prominent feature of smaller fish. Confusing species include the Moses Perch, which has a black spot on its side and the Black Cod (see protected species page) which inhabits similar habitat.

This species spawns in late spring to early summer and juveniles drift on the prevailing currents before settling in estuaries and on shallow rocky reefs.

The Mangrove Jack will respond to burley, but the main challenge is locating the fish in the first place. Looking for good cave systems close by to baitfish and near the sandline seems to be the best approach.
