everything about the dogteeth weakfish
who is the dogteeth weakfish
The toothy croaker is a fish of the family Sciaenidae, found in bays, estuaries and coastal waters of the eastern Pacific, from Panama to Ecuador, including the coast of Colombia. It reaches 50 cm. It feeds on crustaceans, fish and squid. It lives in bays and estuaries, where it finds its prey. It is considered a good fish to eat and appears in commercial fishing. It has an elongated body and a dorsal fin divided into two parts, like the other croakers.
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 dogteeth weakfish.
identification
Elongated body, typical of croakers, with large teeth, which give it its popular names of toothy croaker and biter. Like the other croakers, it has a dorsal fin divided into two parts. It reaches 50 cm and lives in bays, estuaries and coastal waters from Panama to Ecuador. Its strong teeth are the main feature for recognizing the species in the field.
where found
Eastern Pacific, from Panama to Ecuador, including the coast of Colombia, in bays, estuaries and coastal waters.
Habitat: Bays, estuaries and coastal waters of the eastern Pacific.
rules for the dogteeth weakfish
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.
Harmless to anglers. Its teeth are strong: hold it carefully and release it without squeezing its mouth.
in the kitchen
It is considered a good fish to eat.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00372, b = 3.21; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
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:
