everything about the congro-rosa
who is the congro-rosa
The pink cusk-eel is an ophidiid with an elongated body, lacking a clear division between the dorsal fin, tail, and anal fin, that lives on mud bottoms of the outer shelf, from Rio de Janeiro to northern Patagonia in Argentina, usually from 60 to 200 m. It lays eggs that float wrapped in a gelatinous mass. It is caught by trawl and bottom line fishing and appears in recreational fishing on deep trips over soft bottoms. It has white, firm flesh, prized in caldeirada and stews. Its taxonomic status is debated: some authors consider it an unspotted form of the southern cusk-eel (Genypterus blacodes).
fun facts
- The pelvic fins have become two filaments under the throat that look like barbels.
- The eggs float in a gelatinous mass.
identification
Elongated body tapering toward the tail, pink to orange, without marked spots. Long dorsal and anal fins, joined to the caudal fin. Pelvic fins reduced to two filaments under the throat, which look like barbels. Very small scales. Despite the name, it is not related to the true congers, which are eels.
where found
From Rio de Janeiro to Rio Grande do Sul, continuing to Uruguay and Argentina.
Habitat: Mud bottoms of the outer shelf and slope edge, usually 60 to 200 m.

when to fish
best season
Fished all year; the sea defines the fishing windows.
best time of day
Any time. At depth light matters little; it bites throughout the day.
what affects the congro-rosa
sensitivity The little bars show how much each factor affects this species. Five full: it feels it a lot.
cold and cold fronts
Lives in cold bottom water.
atmospheric pressure
A cold front brings rough seas.
moon
Small effect.
rain
No effect at depth.
water level
Does not depend on water level.
noise
Not very sensitive.
wind
Strong wind prevents keeping the line vertical.
tide
Prefer weak current.
depth
60 to 200 m.
how to fish

tip from an angler
Leave the bait still on the bottom; the cusk-eel bites slowly.
rules for the congro-rosa
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
Conservation: Not on the national list (Portaria GM/MMA 1.667/2026). We found no specific federal rule for this species.
We found no species-specific rule beyond the region's general rules.
catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.
Comes from great depth and rarely survives release; keep only what you will eat.
in the kitchen
White, firm, tasty flesh; classic in caldeirada, stew, and grilled steaks.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00209, b = 3.18; FishBase (estimativa bayesiana, comprimento total)). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
The season weights (months), the time of day and the sensitivities (cold, pressure, moon, wind, rain, tide, strong light, murky water and noise) are the app's editorial estimates, based on the literature below and on the field experience of anglers and guides. They are not official data nor a measurement made for this species, and they may vary by region and year. Closed seasons and legal rules appear in the rules section, with the norm and a link.

where each number comes from
The weather comes from three independent global models, cross-checked hour by hour: when they agree, confidence goes up; when they diverge, the band between them shows on the chart. Beyond 16 days, we use the GEFS ensemble of 31 simulations: if 20 of the 31 predict rain, the chance of rain is 65%. Sun and moon are calculated astronomically, with no uncertainty.
The index adds up, weighted for each species: time of day (species curve anchored to real sunrise and sunset), moon (transits, rise and set, phase), pressure (3 h trend and 24 h swing), water temperature (in rivers, estimated from air temperature; at sea, estimated by an ocean model), wind, rain, clouds, tide and the month in the species' cycle.

how accurate the forecast is
Accuracy measured in the reference project (4 regions, 93 days, forecast vs. observed): maximum temperature is off by 0.6 °C on average the next day and 1.7 °C at 7 days; rain of 5 mm or more is detected 76% of the time the next day and 57% at 7 days. Detection isn't everything: the false alarm rate isn't published here yet, and 93 days in 4 regions is still a small sample. We now also measure every day, at the app's destinations:
