How to Catch a Sweetlip Emperor

The sweetlip emperor is also referred to as a sweetlip swoose and a tricky snapper. This fish can get up to 35 inches in length and weigh over 11 pounds. It is a light grey fish with small black scale centers that are dotted around their body. On the top or back of the fish, is its first dorsal fin, which is red and as the fin moves toward the tail it becomes darker. Around the base of its pectoral fin it is either orange or red and is located behind the head on its chest. On parts of the bottom fin, around the eyes, or on the corner of the mouth it can also be orange or red. They can also be olive green on top with an olive-brown body. They are identifiable by their bright red dorsal fin and its large mouth is also bright red inside.

Sweetlip emperors are considered a carnivorous predator in the reef but they mainly eat sand dollars, small fish, and small crustaceans like crabs. A sweetlip emperor will also eat other organisms that live near the reef bottom. They are a threatened species because both recreational fishermen and commercial fishing operations like to catch them because of their taste and lovely colors.

Where to Find a Sweetlip Emperor

The sweetlip emperor is a fish that you can find in moderately warm waters and coral reefs in the Western Pacific Ocean. Its primary habitat is the Great Barrier Reef. You can also find it in the center of Western Australia around the coastal regions. Although they live at the bottom of the reef, they will only be found where the bottom is light and sandy, which is on the continental shelf. They choose to live near a reef for protection from predators.

How to Catch a Sweetlip Emperor

They respond well to burley, which is when you release small amounts of fish into the water in order to attract the sweetlip emperor to your location where you have your baited hook. Sometimes they will get brazen in their eating, making it easier for you to catch them. They are a bottom fish so you have to catch them by using bottom fishing methods. 

When you hook a sweetlip emperor, it will fight hard to get away. It will quickly swim to the bottom to try and break the line. This can happen if you are not quick to reel it in. Remember that when you are fishing in deep waters, cast with the current and not against it. You also have to make sure that you get the lure as close to the bottom as possible.

Best Bait for Sweetlip Emperor

Although the sweetlip emperor will take most bottom bouncing baits, the most successful bait is fresh fish flesh bait. They like bait such as cut-up squid, pilchard, prawn, mackerel, and crab. If frozen, wait for the bait to thaw out before placing on your hook.

Best Lures & Tackle for Sweetlip Emperor

A sweetlip emperor does respond well to a soft plastic lure. If you are using a jig, it had better be healthy or it will not survive the onslaught of the sweetlip emperor. For jigs, use the small 2/0 or 3/0 circle hooks rather than a sinker when fishing in the shallows.

Tips and Tactics

  • They will bite down on most bouncing bait but the fish loves fresh raw, cut-up fish.
  • When you handle this spiny fish, be very careful because it has sharp anal spines and dorsal fins. 
  • Before you put it in a cooler that is filled with ice, make sure that you kill it humanely with a firm knock to the head.
  • When fishing in shallow water, use fresh bait to attract the sweetlip emperor to where your boat is anchored.

  • 1 cup of fish sauce
  • 1 cup of soy sauce
  • 1 tablespoon of sugar

Sweetlip Emperor Reproduction

These fish have a strange breeding and development pattern. They spawn all the time off the coast of Cairns but they only mate in June and August off the coast of Townsville. In the more southern waters, spawning time is in October and November off the coast. The difference in water temperatures is the cause of these different breeding times. They can only spa in warmer water.

The young sweetlip emperor lives near the shore in mangrove swamps and sea grass beds where the water is shallow. As they get older, they will start to move out towards the ocean.
