Mebaru Complex

Sebastes inermis complex

Mebaru is a complex of three very close species split in 2008: red mebaru Sebastes inermis, black mebaru S. ventricosus and white mebaru S. cheni, so similar that anglers fish them as one. Night light-tackle lure fishing at piers in winter and spring — 'mebaring' — is the signature scene. In Korea the fish is generally treated as the single species S. inermis.

Identifying features

Large, forward-facing eyes adapted to night feeding
Red, black or whitish-pale body tone depending on the member species
Stocky Sebastes body with spiny dorsal fin and rough scales
Faint dark bars or mottling, clearer in young fish
Pectoral fins large and rounded; tail slightly rounded to truncate

Habits

Nocturnal; rises and hunts around lights and structure at night
Feeds on small shrimp, worms, planktonic crustaceans and tiny fish
Holds in kelp and reef by day, moves out to feed after dark
Ovoviviparous; winter-spring is both the birthing and peak fishing season
Bites are delicate; fish often sip small lures rather than strike hard

How to catch them

Mebaring — night pier lure fishing Shore

Rig: Ultralight spinning rod, 0.5-2 g jig head with a 1.5-2 in (4-5 cm) soft plastic, cast around pier lights and retrieved very slowly

Bait/lure: Small worm- or shrimp-pattern soft plastics

Key tip: Fish after dark around light edges and keep the lure just off bottom with a slow, steady retrieve.

Light bait fishing over reef from shore rock Rock fishing

Rig: Light float or split-shot rig with a small hook over reef and kelp from rocky shore points

Bait/lure: Shrimp or worm pieces

Key tip: Fish dusk into night and strike at the slightest dip — bites are soft and easily missed.
