everything about the pink cusk-eel
who is the pink cusk-eel
Cusk-eel of the family Ophidiidae, with an elongated, compressed body of yellowish-pink color, marbled on the back by irregular reddish blotches. It reaches 200 cm and up to 25 kg. It lives in deep waters, from 22 to 1000 m, and is most common between 300 and 550 m. Juveniles stay in shallower shelf waters. It mainly eats crustaceans, such as squat lobsters and langoustines, and also fish. It lays floating eggs. It is of great importance to commercial fishing.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the pink cusk-eel; in the meantime, see the similar species.
fun facts
- It lays floating eggs, grouped in a gelatinous mass.
identification
Yellowish-pink body, with irregular reddish-brown blotches marbling the back. It is elongated and compressed from the sides, with long dorsal and anal fins typical of the family. The pink color and marbled back are the main signs for identifying it, along with the long body and large size.
where found
It occurs in the southwestern Atlantic, in Brazil, Uruguay and Argentina, and also in the Pacific, in Chile, Australia and New Zealand.
Habitat: Deep waters, usually between 300 and 550 m, with juveniles in shallow shelf waters.

rules for the pink cusk-eel
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 Brazilian national list (Ministerial Ordinance GM/MMA No. 1.667/2026).
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.
It is not dangerous. As a bottom fish, the pressure change on ascent can cause barotrauma; if released, do it carefully.
in the kitchen
Sold fresh, frozen or smoked, and can be fried or baked.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00224, b = 3.16; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
Essential profile: size, length-weight, depth, countries and conservation come from FishBase and the cited regulations, and the texts were written from those sources. Season, time of day, sensitivities, technique and baits and lures are not included yet, because we did not find a good source for this species.

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:
