everything about the deep-sea sole
how to recognize it
Flatfish with a short, deep body, with the dorsal fin starting above the rear edge of the upper eye's pupil. The tail is almost rounded and the pectoral fins are short. It lives on mud bottoms at great depth. It is of the same genus as the Dover sole (Microstomus pacificus), but smaller: it reaches 47 cm, against 76 cm.
Also called: linguado-de-águas-profundas, platija de profundidad, Deep-sea sole

We don't have tips on season, bait or technique for this species yet.
where found
open on the large mapWhere to look: Mud bottoms at great depth, from 41 to 1,800 m, usually 500 to 950 m.
In Latin America, the species occurs in Mexico, near the northern border. The rest of its range runs from Japan to the Gulf of Alaska.
rules for the deep-sea sole
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.

how we calculate
Length-weight relationship W = a·Lb (a = 0.00955, b = 3.15; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.
more about the deep-sea sole
The deepsea sole is a flatfish of the family Pleuronectidae that lives on mud bottoms at great depths. It occurs in the North Pacific, from Japan to the Gulf of Alaska, up to the border with Mexico. Records range from 41 to 1,800 m, but it is most common between 500 and 950 m. It reaches 47 cm. It is caught for subsistence and is considered of sport interest. Since it lives at great depths, fish brought to the surface may suffer barotrauma.

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.

how we calculatewhere 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:
