everything about the pacific seahorse
how to recognize it
Rigid body, covered in plates, with the head bent at an angle to the trunk and a tube-shaped snout. The tail curls and is used to hold onto branches. Its color matches the surroundings, and the seahorse usually stays camouflaged among gorgonians and black corals. Pipefish, of the same family, have long, straight bodies, while the seahorse is curved and stays upright.
Also called: cavalo-marinho-do-pacífico, caballito de mar, Pacific seahorse
We don't have tips on season, bait or technique for this species yet.
where found
open on the large mapWhere to look: Reefs, among branches of gorgonians and black corals, generally from 3 to 18 m and down to 60 m.
Occurs in the eastern Pacific, from San Diego, California, to Peru, including the Galápagos. In Latin America, it ranges from Mexico to Peru, on shallow reefs. There are no records on the Brazilian coast.
when to fish
best time of day
Nighttime. Nocturnal species, camouflaged among the branches of gorgonians and black corals.
rules for the pacific seahorse
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.
IUCN global: VU · vulnerable.

how we calculate
Length-weight relationship W = a·Lb (a = 0.00447, b = 3.0; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.
more about the pacific seahorse
The family Syngnathidae brings together seahorses and pipefish, with a body covered in plates and a tube-shaped snout. This species reaches 30 cm and lives on reefs in the eastern Pacific, from San Diego, California, to Peru, including the Galápagos. It usually stays between 3 and 18 m, but goes down to 60 m, coiled around branches of gorgonians and black corals, where it camouflages itself. It is nocturnal. It has no interest for sport fishing: it is sold for aquariums and appears in commercial fishing, and the species is threatened.
Family: Syngnathidae · forage fish
fun facts
- The male carries the eggs in a pouch under the tail, and gestation lasts 14 to 15 days, depending on the temperature.
- It has already been found in the stomachs of tunas, which shows that it is food for large predators.

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:
