everything about the speckled squirrelfish
how to recognize it
Silvery-reddish body, bluish and shiny on the back, with scales finely dotted with black. The spiny dorsal fin is white-silver, with a broad red margin. The mouth is small and almost terminal, and the preopercle spine is short. Compare it with Myripristis berndti, which has a protruding lower jaw and a red lower half of the fins.
Also called: mariquita-pintalgada, speckled squirrelfish

where found
open on the large mapWhere to look: Crevices, tunnels and ledges of shallow reefs, spreading over sand at night.
Occurs in the Indo-Pacific, from the Red Sea to Hawaii, and in the eastern Pacific as far as Easter Island, Chile.
when to fish
best time of day
Nighttime. By day it stays in reef tunnels and crevices; at night it spreads over sand and open bottom to feed.
rules for the speckled squirrelfish
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.

how we calculate
Length-weight relationship W = a·Lb (a = 0.0138, b = 2.98; 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 speckled squirrelfish
The spotted squirrelfish belongs to the family Holocentridae, the squirrelfishes and soldierfishes. It reaches 23 cm and lives on shallow reefs, in crevices and ledges, from the Red Sea to Hawaii and Easter Island, Chile. It usually stays between 1 and 30 m deep. By day it stays in crevices and, at night, spreads over sand bottoms to feed on small crustaceans, crustacean larvae and polychaete worms. It has commercial use and is also sold for aquariums.

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:
