Overview

Blue Morwong — also known in some regions as Queen Snapper — are a deep-water South Australian reef fish with a slate-grey to blue body and long trailing pectoral fins. They live over deeper offshore reef and rough ground, fight hard on light tackle, and are an excellent table fish.

Identification

A deep-bodied, slate-grey to silvery-blue reef fish with a small mouth, long trailing pectoral fins and a forked tail. Larger fish carry a distinctly blue-grey hue over deep structure.

Slender trailing pectoral fins, deep body, small mouth and slate-blue to grey colouring over deep reef — unlike shallower-dwelling morwong species.

SIMILAR SPECIES

Jackass Morwong are shallower-dwelling with a dark band across the body; Blue Morwong are deeper-bodied, bluish-grey, and usually caught in deeper water over offshore reef.

How to Catch Them

Anchor or drift over deep reef, drop a lightly weighted baited rig to the bottom and lift it just off, then hold on. Berley draws fish; keep baits small and near the structure. A slow, steady fight follows hookup.

Small fresh baits of squid, prawn or fish fillet on strong but small hooks, presented just above the bottom on a light paternoster.

BITE BEHAVIOUR

A firm tap and steady weight — blue morwong bite confidently and load the rod quickly.

HOOK SETTING

Lift smoothly into the weight; blue morwong hook themselves against a light sinker once the bait is taken.

BEGINNER TIPS

Locate deep reef on your sounder and drop small baits over the edge with a light berley trail. Blue morwong are a consistent deep-water species once you find the right ground.

COMMON MISTAKES

Fishing too heavy, using hooks that are too large, and not keeping baits small — blue morwong have small mouths.

Keeping Your Catch

HANDLING

Support the body with wet hands; deep-water fish are delicate when brought up — hold gently and release unwanted fish quickly.

BLEEDING

If keeping, dispatch and bleed promptly before icing.

ICING

Slush ice promptly; blue morwong flesh firms and stays sweet when chilled.

Cleaning & Filleting

CLEANING

Gut, scale and rinse. Blue morwong scale easily and gut cleanly.

FILLETING

Fillets come off cleanly along the backbone; the body is solid enough for full fillets.

SKIN

Skin is thin and crisps well when pan-fried or grilled skin side down.

BONES

Few pin bones; feel the fillet and pull out any you find with pliers.

Cooking

Pan-frydeep-frygrilling whole

Sweet, white, firm flesh — pan-fry in butter, crumb and deep-fry, or grill whole. Blue morwong are superb table fare.
