everything about the green sturgeon
how to recognize it
Elongated body, with a row of bony plates along the middle of the belly, between the anus and the anal fin. The dorsal fin begins in the last third of the body. Back olive green to dark green, with a whitish belly and an olive green longitudinal stripe on each side. The barbels are closer to the mouth than to the tip of the snout. The pectoral fins are large and rounded, and the other fins are grayish to pale green.
Also called: esturjão-verde, esturión verde, green sturgeon

where found
open on the large mapWhere to look: Estuaries, river mouths and brackish or salt water near the coast, down to 80 m.
It occurs in Mexico, on the North Pacific coast, as far as Ensenada, in Baja California.
rules for the green sturgeon
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.

how we calculate
Length-weight relationship W = a·Lb (a = 0.00295, b = 3.18; 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%.
more about the green sturgeon
A sturgeon of the family Acipenseridae, up to 2.7 m and 159 kg, with a recorded age of up to 60 years. It occurs on the North Pacific coast, from Alaska to Mexico, in estuaries, the lower reaches of large rivers, and in salt and brackish water near river mouths. It lives close to the bottom, from sea level down to 80 m, and can travel long distances in the ocean. Adults probably spawn in fresh water. In fishing it sometimes appears as a sport fish, and it has a small commercial fishery.
Family: Acipenseridae · omnivore

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.

how we calculatewhere 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:
