everything about the ember parrotfish
who is the ember parrotfish
The violet parrotfish belongs to the family Labridae and reaches 70 cm. It lives alone or in pairs on reefs exposed to the sea, on stone or coral bottoms, from 1 to 36 m. On slopes with boulders, at the base of cliffs of high islands, it may form large schools. It occurs in the eastern Pacific, from the Gulf of California to the Galápagos, and also in the Indo-Pacific. It eats algae from the bottom and is protogynous: born female, it can change into a male. Males have two colors, brown to dark green on the head and front of the body, and lighter green toward the rear. It is an uncommon species, commercially caught and used in 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 ember parrotfish; in the meantime, see the similar species.
fun facts
- The change of sex, from female to male, occurs at about 37 cm and 13 years of age.
identification
Parrotfish with males in two sharply separated colors: the head and front of the body are dark, and the rear is lighter. The female is reddish to grayish, with small black spots and irregular dark lines on the body. Older males have the tail with elongated lobes, which helps identify them.
where found
Occurs in the eastern Pacific, from the Gulf of California to the Galápagos, on reefs and slopes, and also in the Indo-Pacific.
Habitat: Rocky or coral reefs and slopes, 1 to 36 m, sometimes in pairs.
rules for the ember parrotfish
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. As a large reef fish, hold it with both hands and release it carefully to avoid injuring its body.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01479, b = 3.05; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). 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:
