everything about the vermelho-profundo
who is the vermelho-profundo
The deepwater redfish belongs to the family Sebastidae, has a fusiform body, and reaches 33.9 cm. It lives in deep water, near the bottom, in the southeast Pacific from Peru to Chile, including the Juan Fernández Islands, and in the southwest Atlantic, off Argentina. It has little commercial value and is not dangerous to anglers. It is viviparous, that is, the females carry the young inside the body. Because it lives on deep bottoms, it suffers from the pressure change when brought to the surface.
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 vermelho-profundo; in the meantime, see the similar species.
identification
Fusiform body, with irregular dark marks on the dorsal fin and the upper part of the body. These marks are the main feature for recognizing it. It has firm fin spines, typical of the family. It differs from the Patagonian redfish (Sebastes oculatus), which has five well-marked dark blotches on the back and four or five spots on the sides.
where found
In Latin America, it occurs in Peru, Chile and Argentina, in deep waters of the southeast Pacific and southwest Atlantic.
Habitat: Bottom, in deep waters.
rules for the vermelho-profundo
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
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.
No danger to anglers. Because it lives on deep bottoms, it suffers from the pressure change on the way up (barotrauma): release it with care and, preferably, with the fish still in the water.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01047, b = 3.09; FishBase (relação peso-comprimento bayesiana, estimativa)). 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:
