everything about the cascudo-graveto-reticulado
who is the cascudo-graveto-reticulado
The reticulated twig cascudo is a freshwater armored catfish of the family Loricariidae, reaching 15.3 cm. It occurs in the Essequibo, Marowijne and Oyapock river basins in the Guianas, in shallow, shaded streams with strong current and rocky bottoms. Its body is so thin it looks like a twig, and by day it hides in crevices in logs. It feeds on periphyton, the slime and organisms that grow on stones. The pair picks a narrow hole to spawn in, and the male guards the eggs. It has commercial fishing and is used in the aquarium trade.
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-graveto-reticulado; in the meantime, see the similar species.
fun facts
- Because it mimics a twig, it goes unnoticed among logs and stones.
identification
Very thin, long armored catfish that looks like a twig, hence the name. It can be confused with the rugose twig cascudo (Farlowella rugosa), which lives in the same Guianas. Both are slender stream armored catfish, and telling them apart requires a close look. This one reaches 15.3 cm, while the rugose one is larger, up to 21.4 cm.
where found
Essequibo, Marowijne and Oyapock river basins in the Guianas, in freshwater streams.
Habitat: Shallow, shaded streams with strong current and rocky bottoms in the Guianas.
rules for the cascudo-graveto-reticulado
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.
No known danger to anglers. Because it is very thin and long, hold it carefully so you don't hurt it.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00398, b = 3.11; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.

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:
