everything about the god's flounder
who is the god's flounder
Flatfish of the family Cyclopsettidae, with a flat, oval body and both eyes on the left side, as in the whole family. It reaches 35 cm, and its common size is 25 cm. It lives on soft bottoms, from shallow estuaries down to 44 m, and the species is recorded down to 50 m, in the eastern Pacific, from the Gulf of California to Peru. Adults form defined pairs during spawning. It is used in subsistence fishing, and the flesh is eaten fresh.
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 god's flounder; in the meantime, see the similar species.
identification
Flat, oval body with both eyes on the left side, like the flatfish of the family Cyclopsettidae. It is recognized by its shape and habitat: soft bottom of shallow estuaries and areas down to 50 m. It lives on the same bottoms as other eastern Pacific flatfish, so location alone is not enough to tell them apart.
where found
Eastern Pacific of Latin America, from Mexico to Peru, on soft bottoms of estuaries and shallow water.
Habitat: Soft mud and sand bottom, from shallow estuaries down to 50 m.
rules for the god's flounder
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 is recorded. Hold the fish by the body, without squeezing, and release it carefully.
in the kitchen
Eaten fresh.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00977, b = 3.07; 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:
