Perch, Crimson Sea

(Lutjanus erythropterus)

Commonly referred to as small mouth nannygai!

A member of the lutjanid family the crimson sea perch has been referred to under many names over the years, small mouth nannygai, saddle tail sea perch, crimson tailed sea perch, red fish, crimson snapper and probably many more. They are a vibrantly bright red coloured, spectacular looking species that are exceptionally good on the table. Definitely one of the most prized and powerful reef fish our beloved country has to offer!


Crimson sea perch can be located from as far south as Carnarvon right up to the magnificent Kimberley region throughout W.A. and also from northern QLD up into the N.T.


Crimson sea perch can grow to around 85cm in length and weigh as much as 10kg although most fish encountered throughout Australia average around 4 – 6kg in weight.


Crimson sea perch prefer deeper, tropical waters from 50 – 250 meters in depth with healthy coral reef present. They can also be encountered around deep water wrecks and abandoned rig structures.


Crimson sea perch can be easily identified by their bright red to orange colouration which is similar in appearance to that of its closely related cousin the saddle tailed sea perch. With the only way of telling the two apart being the crimson has a much smaller head and mouth. The saddle tailed sea perch as its name suggests has a saddle like dip located towards the base of the tail.

Tackle requirements

Medium to heavy spin or overhead tackle is well suited to targeting crimson sea perch with medium to heavy strength braided, gel spun or nylon lines with a breaking strain of 30 – 80lb proving ideal. 80 – 150lb nylon leaders should be attached to bright braided or gel spun lines to prevent fish from seeing the line and also to help prevent chafe offs on rough structures. Medium to heavy bottom fishing or jigging outfits in either spin or overhead styles are more typically suited for fishing deeper water to 100 meters and electric reels will be needed for water depths of 400 meters plus.

Recommended baits, lures and rigs

Most standard bottom fishing baits such as cut fish strips, squid and octopus will suffice for most crimson sea perch situations with lures such as soft plastics and metal jigs also proving deadly on this species in northern waters. Paternoster or drift baiting rigs made from 80 – 120lb nylon are normally used to target crimson sea perch in deeper waters to 100 meters and paternoster rigs made from 200lb nylon with large swivels incorporated are necessary for deeper waters of 200 meters plus.

Handy hints and tips

Try to use as fresh a bait as possible and present it in a long strip styled fashion with two snelled hooks. Most importantly remember to let the fish eat it! Don’t pull it away at the first sign of interest.

Preferred fishing times and tides

High and low tide changes are best suited for targeting crimson sea perch in deeper waters and low light periods such as dawn and dusk with a rising tide are best for shallow areas. Neep tides are also necessary the further north you travel.
