everything about the brazilian lizardfish
how to recognize it
Lizardfish of the family Synodontidae, with an elongated body, large mouth and pointed teeth, like the other lizardfish in the family. It lives deeper than Synodus synodus, which usually stays in shallow waters, 2 to 35 m. This species generally stays between 50 and 194 m. To tell them apart, look at depth and where it is found, not only at body shape.
Also called: peixe-lagarto-brasileiro, lagarto brasileño, lagarto, brazilian lizardfish
don't confuse with:
We don't have tips on season, bait or technique for this species yet.
where found
open on the large mapWhere to look: Outer continental shelf bottom, usually between 50 and 194 m deep.
In Latin America it occurs along the Brazilian coast, up to Santa Catarina, and also in Argentina, Uruguay, the Guianas, Venezuela, Trinidad and Tobago, Cuba, Mexico and Nicaragua, on shelf bottoms.

rules for the brazilian lizardfish
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 = 0.00537, b = 3.1; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.
more about the brazilian lizardfish
Fish of the family Synodontidae, with an elongated body and a large mouth with teeth. Reaches 25 cm. It lives on the bottom of the outer continental shelf, usually between 50 and 194 m, and can range from 18 to 410 m. It occurs in the western Atlantic, from North Carolina to Santa Catarina, Brazil, including the Gulf of Mexico and the Caribbean. It is mostly seen in commercial fisheries and is not a fish often seen in sport fishing.

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:
