everything about the curimatã-do-equador
who is the curimatã-do-equador
The Ecuadorian curimatã is a freshwater prochilodontid of the family Prochilodontidae, reaching 24 cm. It is native to Ecuador, in the Guayas and Santiago river basins, in the midwater and near the bottom, in tropical water. It has the elongated, robust body of curimatãs, with the mouth turned downward. It has commercial fishing and is raised in aquaculture systems. For rod-and-reel anglers it is not a featured species, but it is part of local commercial 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 curimatã-do-equador; in the meantime, see the similar species.
identification
Elongated, robust fish with a downturned mouth and thick lips, like curimatãs. Reaches 24 cm. Lives in the Guayas and Santiago river basins in Ecuador. The curimatã (Prochilodus nigricans) also occurs in Ecuador, but on the Amazonian side of the country, and is larger.
where found
Guayas and Santiago river basins in Ecuador, in tropical freshwater.
Habitat: Rivers of the Guayas and Santiago basins in Ecuador, in the midwater and on the bottom.
rules for the curimatã-do-equador
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 known danger to anglers. Hold it with both hands and release it right away.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.0166, b = 2.98; 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:
