everything about the smalleye flounder
who is the smalleye flounder
The small-eye flounder is a fish of the family Paralichthyidae that lives on the bottom in the southeastern Pacific. In Latin America, the species occurs only in Chile, between 18°S and 51°S. It reaches 41 cm and 798 g. It is a flatfish with a short, deep body. It is used in commercial fishing. In Chile it is called lenguado de ojo chico or de ojos chicos, names that mean small-eyed flounder.
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 smalleye flounder; in the meantime, see the similar species.
fun facts
- The published maximum weight is 798 g.
identification
Flatfish with a short, deep body, flattened like the other flatfish of the family, with both eyes on the same side of the head. The name suggests small eyes. It lives on the bottom off the coast of Chile. On the same coast also live the Pacific flounder (Paralichthys adspersus), of the same genus, and the bigeye flounder (Hippoglossina macrops), of a different genus.
where found
In Latin America, the species occurs in Chile, in the southeastern Pacific, between 18°S and 51°S.
Habitat: Sea bottom off the coast of Chile.
rules for the smalleye 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.
It has no spines or venom. Release it carefully and do not squeeze the body when removing the hook.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00676, b = 3.16; FishBase (relação peso-comprimento bayesiana, estimativa pelo gênero e formato do corpo)). 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:
