The common snook (Centropomus undecimalis) is a species of marine fish in the family Centropomidae of the order Perciformes. The common snook is also known as the sergeant fish or robalo.

One of the largest snooks grows to a maximum overall length of 140 cm (4.6 ft), but common length is 50 cm (1.6 ft). The IGFA world record is 24.32 kg (53 lb 10 oz) caught in Parismina Ranch, Costa Rica, by Rafael Montalvo. 

Of typical centropomid form, it possesses drab coloration except for a distinctive black lateral line. It can also have bright yellow pelvic and caudal fins, especially during spawn.



The common snook is an estuarine and freshwater-dependent fish species. Within estuaries, juvenile common snook are most often found inhabiting areas such as coastal wetland ponds, island networks, and creeks. Despite being a euryhaline species of fish, the common snook does show a tendency to gravitate towards lower-salinity conditions in the early stages of its life.

Occurring in shallow coastal waters, estuaries and lagoons, the fish often enter fresh water.


They are carnivorous, with a diet dominated by smaller fishes, and crustaceans such as shrimp, and occasionally crabs.


Gear and equipment

Live shrimp, live pilchards, live mullet, and live sardines can all work depending on where you are fishing.  As with most bait fishing it's usually best to catch some bait near the area you will be fishing.  Snooks have a hard time turning down a lively bait fished near their ambush points such as docks and mangroves.

How to catch a Snook? 

Use a light saltwater spinning or baitcasting setup, but make sure that the braid can withstand 30 lbs. The fluorocarbon leader you use should be able to pass a 15 lb for the smaller snook to a 40 lb test if you are fishing for giant snook. The best snook lures are bucktail jigs that come attached with plastic tails. You can also use soft plastic lures like DOA Shrimp and Jerk Shads as well as several types of topwater plugs. The plugs will come in handy if you are fishing in low light such as early morning or twilight.
