everything about the tropical pomfret
how to recognize it
A short, deep body, of the typical pomfret shape, with a large eye. Identification relies mainly on habitat: open sea and deep bottom, near large islands. It is told apart from the lira (Taractes rubescens), which lives from 0 to 600 m, by generally living deeper, between 384 and 1,317 m.
Also called: olho-de-ovo, brama clara, tropical pomfret

rules for the tropical pomfret
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.
Conservation: Not on the Brazilian national list (Ministerial Ordinance GM/MMA No. 1.667/2026).

how we calculate
Length-weight relationship W = a·Lb (a = 0.01778, b = 2.96; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.
more about the tropical pomfret
The egg-eye (olho-de-ovo) belongs to the family Bramidae (pomfrets) and reaches 61 cm and 3.1 kg. It lives in the open sea, at depths of 384 to 1,317 m, with a mesopelagic and bathypelagic habit. The known adults were caught near large islands. It feeds on fish, crustaceans, cephalopods and worms. In Latin America it occurs in Colombia, Cuba, the Bahamas and Brazil, at Fernando de Noronha and in Bahia, and it is of sport interest.

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:
