Overview

Also known as sweetlips, red throat, Lipper, yellow mouthed perch, red-throated emperor, and sweetlip swoose, the sweetlip emperor is instantly recognizable by its large lips and snout. The area around the eyes of this unique looking fish is orange in color, and its body is light gray with a few black scales in between. The best way to determine whether the fish you caught is a sweetlip is by checking its mouth, which should be a brilliant red.

Sweetlips can be found around the Abrolhos Islands in Australia and around New South Wales. At most, it can grow up to 35 inches in length and can weigh over 11 lbs. It usually feeds on invertebrates, smaller fish and crustaceans along the seafloor.

A fascinating sweetlip emperor fish fact is that it fights well and fights hard when it is hooked. Once it is caught, it quickly swims to the bottom to try and break the line, which can happen if you are not quick enough to reel it in. The fish is easily lured with common bait such as cut-up pilchard, squid, crab, prawn, and mackerel. However, they respond particularly well to soft plastic lures.

If you are fishing in deep waters, make sure that you cast with the current rather than against it and make sure the lure is as close to the bottom as possible. If you use a jig, it has to be healthy, or it will not survive the emperor onslaught!

Sweetlip Emperor Fishing Tactics

 
  • Sweetlips can bite down on most bouncing bait, but it cannot resist fresh ones, especially raw, cut-up fish.
  • Be very careful when you are handling this spiny fish. It has sharp dorsal and anal spines, which can puncture skin and muscle quickly. Kill the fish humanely with a firm knock to the head before placing it in a cooler that is filled with ice.

Sweetlip Emperor Fishing Tips

  1. If you are fishing in the shallows, use fish bait to attract the fish to where you are anchored.
  2. Use small 2/0 or 3/0 circle hooks for jigs rather than a sinker when you are fishing for the emperor in the shallows.

Sweetlip Emperor Seasons

The sweetlip emperor fish has a strange breeding and development pattern. For example, it frequently spawns off the coast of Cairns, but, in Townsville, the fish spawns in June and August. Similarly, they spawn in October and November in southern waters.

This may have to do with different water temperatures, which have to be warm, or the fish refuses to spawn.

How to Clean Sweetlip Emperor

  1. Place the sweetlip emperor on a clean surface making sure that its stomach is towards you.
  2. Starting from the top of the head, start slicing down to the rib bone using a sharp fillet knife.
  3. When you reach the bottom, turn the fish around, so its spine is towards you and continues cutting by angling the knife towards the spine. Work the knife along the backbone and cut all the way down to the other side as you saw through the fish.
  4.  Keep cutting till the knife cuts out from just above the tale.
  5. At this point, the fillet is still attached to the fish. Make multiple passes with the knife along the incision you made and over the ribs till the fillet comes off.
  6. Flip over the fish and cook the other side to get the second fillet.

  • Make a mixture of a cup of soy sauce, a cup of fish sauce, and a tablespoon of sugar and pour it over the fish, which should be in a deep tray.
