Lebrancho
Lebrancho (Mugil liza) is a coastal mullet native to Argentina's Atlantic seaboard, found from estuaries and brackish lagoons down to the Río de la Plata and beyond.
Commercially important and increasingly targeted by sport anglers, it's a bottom-grazer that tests light tackle with its stubborn, bulldogging runs in shallow coastal water.
Scientific Name: Mugil liza
Also known as Lisa, Lisa de agua dulce
- Elongated, torpedo-shaped body; dark bluish-grey on the back fading to silver on the flanks, with faint dark horizontal stripes along the sides.
- Flat-topped head, small terminal mouth with thin lips and a distinctive fleshy bump on the lower lip — a reliable ID feature that separates it from other mullets.
- Large, nearly opaque adipose eyelid covers most of the eye — visible in hand and unique to this family.
- Typical fish run 30–50 cm; larger individuals can reach 80–100 cm, with fish over 60 cm considered a solid catch on light gear.
What to know
Habitat Distribution
- Native to Argentina's Atlantic coast; ranges from the Río de la Plata estuary south along the Buenos Aires province coastline.
- Primarily a coastal marine and estuarine fish — lives in bays, tidal creeks, and brackish lagoons, but will push into freshwater reaches of coastal rivers.
- Depth range is mostly 0–10 m in tidal zones, though it can be found to 125 m offshore; anglers encounter it almost exclusively in the shallows.
- Listed as rare in Argentine freshwater assessments, so most encounters are in saltwater or brackish coastal systems rather than inland rivers.
Key Locations
- Río de la Plata estuary — the broad brackish zone where the river meets the Atlantic is the core of its Argentine range and the most accessible fishery.
- Buenos Aires province coastal bays and tidal lagoons — shallow estuarine systems along this coastline hold resident populations through the warmer months.
Specific Spots
- Tidal flats and shallow sandy or muddy bottoms near river mouths — lebrancho root through soft substrate for algae and detritus, so follow the tide onto the flats.
- Estuarine channels and creek mouths where freshwater meets salt; current breaks at these junctions concentrate feeding fish.
- Brackish lagoons and coastal bays with weed growth or soft-bottom structure — mullet graze these areas methodically, often visible as surface disturbances or tailing fish.
Lebrancho FAQ
Answers from onWater's species guide.
What are the best lures and bait for Lebrancho?
Bread paste, dough baits, and small pieces of mussel or prawn fished on the bottom are the most reliable; match the soft, plant-based diet rather than reaching for hard lures.
When is the best time to fish for Lebrancho?
Spring and summer (October–March) bring the best inshore fishing as warming water pushes fish onto shallow flats and into estuaries. Spawning occurs offshore during the warmer months; post-spawn fish return inshore and feed actively through late summer and autumn (February–April).
How do you catch Lebrancho?
Shore fishing with light spinning gear is the standard approach along the Buenos Aires coast and Río de la Plata estuary. Anglers locate feeding schools visually on shallow flats or in tidal creeks, then present small natural baits on a running sinker rig, often with a berley trail to hold the school in range.
What do Lebrancho eat?
Feeds mainly on filamentous algae, detritus, and organic material scraped from the bottom, not a predator chasing baitfish. This makes conventional lure fishing less effective; small dough baits, bread paste, or finely ground berley (chum) presented on the bottom are the standard approach.
Where do Lebrancho live?
Native to Argentina's Atlantic coast; ranges from the Río de la Plata estuary south along the Buenos Aires province coastline. Primarily a coastal marine and estuarine fish, lives in bays, tidal creeks, and brackish lagoons, but will push into freshwater reaches of coastal rivers.
