everything about the carolines parrotfish
how to recognize it
Grayish-brown parrotfish when fresh, with scales that have fine whitish lines and a reddish-brown tone on the belly. The head is lighter underneath, with an indistinct orange-brown line from the eye to the upper lip and three short reddish lines behind the eye. The skin is black around the anus, and the pelvic fins are reddish-brown with spots. The tail is rounded in juveniles and has longer lobes in large males.

where found
open on the large mapWhere to look: Shallow reefs, lagoons and outer reefs, with coral, gravel, seagrass and algae, from 1 to 71 m.
In Latin America it is recorded in Mexico, in the Revillagigedo Islands, on shallow reefs, lagoons and areas of algae and seagrass. The species occurs throughout the Indo-Pacific.

how we calculate
Length-weight relationship W = a·Lb (a = 0.0138, b = 3.06; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.
more about the carolines parrotfish
The green-toothed parrotfish belongs to the family Labridae and reaches 54 cm. It is the species with the widest range in its genus, from East Africa to the eastern Pacific, and in Latin America it is recorded in Mexico, in the Revillagigedo Islands. It lives alone or in small groups on shallow reefs, lagoons and outer reefs, from 1 to 71 m, and is found at least down to 27 m, in areas of coral, gravel, seagrass and algae. It scrapes encrusting algae, such as Padina. It is protogynous: born female, it can change into a male. It is caught with nets and other artisanal gear and sold for the aquarium trade.

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.

how we calculatewhere 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:
