the species
everything about the cachara
overview
who is the cachara
A leather catfish of the Pantanal and the Paraná, a close relative of the pintado. It is more abundant than it in many Pantanal rivers and comes closer to the shore, into the camalote mats and corixo mouths. At night it hunts tuviras, muçuns and small fish, using its barbels. During falling water it concentrates at bay outlets, the classic spots. It fights with strong pulls and tries to tangle in water hyacinth and submerged timber. It has strict rules: transport banned in MT, keeping banned in PR and a size window in MS.
fun facts
- In older laws it appears as Pseudoplatystoma fasciatum; the current name for the Plata basin is P. reticulatum.
- Crossed with the pintado in captivity, it produces the "ponto e vírgula" hybrid.
how to recognize it
identification
Long, flat head like the pintado's, but a little shorter. The flank has broad, wavy dark bands that join into a net, with pale areas between them and few spots. The pintado has many round spots and fine pale bands. The jurupoca has a duck-bill-shaped snout, a longer lower jaw and few large spots.
distribution
open on the large map where found
Rivers and bays of the Pantanal (Paraguay, Cuiabá, São Lourenço, Piquiri, Taquari, Negro, Miranda, Aquidauana) and the Paraná main channel.
Habitat: Bay and corixo mouths, shorelines with camalote mats, banks, backwaters and beaches at night; pools by day.

best season
time of yearbest: May and Aug–Oct
JanFebSeaAprMayJunJulAugSepOctNovDec
Falling water (April to June) is already good, with water flowing out of the bays. The dry season (August to October) concentrates fish in the channels.
best time of day
Night and twilight. Active from dusk until dawn. At first light it still bites along the shore; by day, only on the bottom.
what affects the cachara
sensitivity The little bars show how much each factor affects this species. Five full: it feels it a lot.

cold and cold fronts
A cold snap (friagem) cuts activity; in the following days, fish deeper and slower.
atmospheric pressure
Best with muggy, stable weather.
moon
Dark nights favor the shoreline.
rain
Light rain doesn't bother it.
water level
Water draining from the bays into the river is the trigger: position the boat at the mouth.
noise
Anchor quietly and avoid knocking the hull.
wind
Little effect.
depth
Shoreline 1 to 3 m at night; pool 4 to 10 m by day.

Zero transport in MT: cachara on the banned list
transport, storage and trade banned until Dec 31, 2028MT
Art. 19-B bans for 5 years (since Jan 1, 2024) transporting, storing and trading cachara caught in rivers of MT. Recreational anglers may only keep up to 2 kg or 1 fish for consumption on site (within 500 m of the river), and art. 19-C excludes the species from art. 19-B: in practice, for this species, catch and release only. The law provides for an evaluation after 3 years (2027) that may revise the list. List checked in the consolidated text published by Sema-MT on May 29, 2026; Law 13.159/2025 did not change the list.

MTParaguay (Pantanal)AmazonTocantins-Araguaia
Transport, storage and sale are fully prohibited for 5 years from Jan 1, 2024 for: cachara, caparari, dorado, jaú, matrinchã (Brycon spp.), pintado/surubim (Pseudoplatystoma spp.), piraíba, piraputanga, pirarara, arapaima (pirarucu), trairão and peacock bass (tucunaré, Cichla spp.). For recreational anglers: catch and release only. These 12 species may not even be eaten on site, since the 2 kg or 1 fish limit excludes the art. 19-B list. The law cites jaú as Zungaro zungaro; we also include the Pantanal jaú (Z. jahu) out of caution. The list may still change: § 2 (exotic and predatory species), § 3 (review through study) and the 3-year assessment planned for 2027. A TJMT news report of Jun 2, 2026 confirms the 12 prohibited species. The STF denied a preliminary injunction in the ADIs against the law in 2024; we found no merits ruling.
Paraná: jaú, pintado, cachara, dorado and piracanjuba catch and release only

Possession, killing and transport of these species are prohibited in Paraná's inland waters (Paraná and Atlantic Southeast basins, except the Iguaçu River and the coast). Catch and release only, with immediate release at the same spot.

how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00589, b = 3.1; FishBase (estimativa bayesiana pela forma da subfamília)). It's an average: a fat or lean fish can vary by 10% to 20%.

how we calculate
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:
