everything about the bagre-de-valdivia
who is the bagre-de-valdivia
The bagre-de-Valdivia is a freshwater catfish of the family Diplomystidae, reaching 25 cm. It is endemic to Chile and lives on the bottom of rivers in the south of the country, in the Valdivia region, in a temperate climate. Diplomystidae are a small family of South American catfish, without scales. It has commercial fishing and appears in river sport fishing. The species is vulnerable, so the best option is to recognize the fish and release it.
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 bagre-de-valdivia; in the meantime, see the similar species.
fun facts
- It is endemic to Chile, meaning it does not occur outside the country.
identification
Elongated, bottom-dwelling catfish of the family Diplomystidae, without scales, up to 25 cm. It can be confused with the tollo (Diplomystes chilensis), which also lives in Chile and reaches 23 cm, and with the bagre-do-Bío-Bío (Diplomystes nahuelbutaensis), which reaches 26 cm. The difference is in size and range: this one is from the south of the country, while the tollo is from the center.
where found
Endemic to Chile, in the Valdivia region, in freshwater rivers of the south of the country.
Habitat: Bottom of freshwater rivers in southern Chile, in a temperate climate.
rules for the bagre-de-valdivia
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. As it is vulnerable, release it quickly, with a wet hand, and avoid keeping the fish out of the water.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00457, b = 3.12; 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:
