everything about the smooth stargazer
who is the smooth stargazer
The family Uranoscopidae includes the stargazers, bottom fish with a broad head and eyes on top. This species reaches 32 cm and occurs in the eastern Pacific, from California to Peru, including the Galapagos and Central America; it is rare north of central Baja California. It lives on the bottom, between 13 and 384 m. It feeds mainly on other fish, and juveniles are pelagic and serve as food for tunas. It has no interest for sport fishing, but enters commercial fishing and the aquarium trade.
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 smooth stargazer.
fun facts
- Juveniles are pelagic and serve as food for large tunas.
identification
Broad head, with eyes on top facing upward, and a large mouth also turned up, traits typical of the family. The skin is smooth, as the common name says. It has a spine above the pectoral fin, probably with mild venom, which calls for care when handling. It lives on the bottom, from 13 to 384 m.
where found
Occurs in the eastern Pacific, from California to Peru, including the Galapagos, on sea bottoms from 13 to 384 m. It is rare north of central Baja California. There are no records on the Brazilian coast.
Habitat: Sea bottom, from 13 to 384 m.
rules for the smooth stargazer
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.
It has a spine above the pectoral fin, probably with mild venom. Handle it with care, hold it away from the spine and return it quickly.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01698, b = 3.08; 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:
