everything about the c-o sole
who is the c-o sole
The C-O sole is a flatfish of the family Pleuronectidae that lives on flat bottoms and rocky areas of the North Pacific, from southeastern Alaska to San Quintín Bay, northern Baja California, Mexico. It occurs from 18 to 350 m deep. It reaches 36 cm. It has a short, deep body and a deep, rounded tail. It has little commercial importance, but it is caught with a rod and appears in public aquariums.
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 c-o sole; in the meantime, see the similar species.
fun facts
- Juveniles are common in shallow water in summer, and adults stay deeper.
identification
Flatfish with a short, deep body and a deep, rounded tail. The dorsal fin begins on the blind side, and the pectoral fins are moderately long with blunt tips. It lives on flat and rocky bottoms, from 18 to 350 m. On the same coast, the curlfin sole (Pleuronichthys decurrens) also has the dorsal fin starting on the blind side, but it runs farther forward, to the corner of the mouth.
where found
In Latin America, it occurs in northern Baja California, Mexico, as far as San Quintín Bay.
Habitat: Flat bottoms and rocky areas, from 18 to 350 m.
rules for the c-o 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.
Not dangerous. Release it carefully, since it lives in deep bottoms and can suffer barotrauma.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01622, b = 3.0; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.

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:
