everything about the cascudo-babão
who is the cascudo-babão
The cascudo babão is a fish of the family Astroblepidae, the Andean climbing catfishes, relatives of the cascudos, reaching 10 cm. It lives in rivers and streams on the Pacific slope and in the Magdalena and Orinoco basins, near the bottom. Like other astroblepids, it clings to rocks with a suckered mouth. It spawns with eggs stuck one by one under large rocks. It has commercial fishing and poses no danger to anglers.
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 cascudo-babão; in the meantime, see the similar species.
fun facts
- Spawns with eggs stuck one by one under large rocks.
identification
Elongated fish with skin lacking thick bony plates and a suckered mouth for clinging to rocks. It can be confused with the cascudo capitán, from the same genus and from Colombia, but that one reaches 30 cm, while the cascudo babão stays at up to 10 cm.
where found
Rivers on the Pacific slope and in the Magdalena and Orinoco basins, in Colombia, Ecuador, Peru and Venezuela. Does not occur in Brazil.
Habitat: Current-swept rivers and streams, near the bottom, where the species clings to rocks.
rules for the cascudo-babão
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.
Small rock fish: if caught by mistake, release it without lifting it out of the water, with wet hands.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01047, b = 3.02; FishBase (relação peso-comprimento bayesiana, estimativa pelo gênero e formato do corpo)). 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:
