everything about the north american naked sole
who is the north american naked sole
A flounder of the family Achiridae, up to 22 cm. It is a flat bottom fish that rests on the sediment in coastal waters, from the beach down to 73 m, with records down to 183 m. It occurs from Massachusetts to southern Florida, in the Bahamas, the Cayman Islands and the eastern Gulf of Mexico. In Latin America it is found in the Bahamas. The species has commercial fishing and no major use in rod 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 north american naked sole; in the meantime, see the similar species.
identification
A flat-bodied flounder with both eyes on the same side of the head and no spines in the dorsal and anal fins. It lives in coastal waters, from the beach to 73 m. Another flounder of the same genus, Gymnachirus texae, from the Gulf of Mexico, lives deeper, between 55 and 90 m.
where found
In Latin America it occurs in the Bahamas, in coastal waters, and extends along the eastern United States to southern Florida.
Habitat: Shallow coastal bottoms, 0 to 73 m deep.
rules for the north american naked sole
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.
Harmless to anglers, with no dangerous spines or teeth. When handling it, hold it carefully and avoid damaging the fins.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.0138, 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:
