everything about the peruvian hake
who is the peruvian hake
The Peruvian hake belongs to the family Merlucciidae and reaches 68 cm in males, and females are larger. It lives from the shallow shelf to the upper slope, between 50 and 500 m, in the southeastern Pacific, along the coasts of Ecuador and Peru, from Paita to Huarmey. Adults reach maturity at about 35 cm. Sometimes they stay away from the bottom, in midwater. It is sold fresh and frozen and also goes to fishmeal. It has very high commercial value.
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 hake; in the meantime, see the similar species.
identification
Hake with an elongated body, silvery on the back and silvery-whitish on the belly. The tail fin edge is usually concave, as in other hakes of the region. It lives between 50 and 500 m, near the bottom or in midwater. Telling it apart from the Chilean hake, which lives farther south, depends on details of the head and skeleton more than on color.
where found
Occurs in the southeastern Pacific, along the coasts of Ecuador and Peru, from Paita to Huarmey.
Habitat: From the shelf to the upper slope, from 50 to 500 m, near the bottom or sometimes in midwater.
rules for the peruvian hake
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 poses no danger to anglers. As a deep-water fish, rapid ascent causes barotrauma, so release it carefully.
in the kitchen
It is sold fresh and frozen, and also goes to fishmeal.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00513, b = 3.09; 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:
