everything about the peruvian sea catfish
who is the peruvian sea catfish
Fish of the family Ariidae, a slender catfish that lives near the bottom in marine and coastal waters of Peru. Its head and body are slim and taper backward, with a long, narrow caudal peduncle, and the species reaches 35 cm total length. A silver or reddish band runs along the flank. Part of the catch goes to fresh markets and part is made into fishmeal. The fin spines wound anyone handling it, and for the sport angler it is an occasional catch.
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 peruvian sea catfish; in the meantime, see the similar species.
identification
Slender, elongated, scaleless catfish, with a slim head and a body tapering backward. The tail has pointed lobes, with the upper one longer, and a narrow peduncle. The most striking mark is the silver-to-reddish band running along the flank. Other sea catfish of Peru have a similar body, so telling them apart requires detailed examination.
where found
It occurs in the southeast Pacific, off the coast of Peru, in marine and coastal waters, near the bottom.
Habitat: Near the bottom, in marine and coastal waters of the Peruvian coast.
rules for the peruvian sea catfish
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.
The fin spines cause wounds: use a cloth or glove, remove the hook with pliers, and release the fish with care.
in the kitchen
The flesh is sold fresh, and part of the catch goes to fishmeal.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01072, b = 2.92; 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:
