everything about the swordspine rockfish
who is the swordspine rockfish
Rockfish of the family Sebastidae, genus Sebastes. It grows to 30 cm. It lives on soft bottoms, 70 to 433 m deep, from San Francisco, California, to central Baja California, Mexico. It is viviparous. It stays away from shallow reefs, in a depth band that sets it apart from shore rockfishes. It enters commercial fishing.
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 swordspine rockfish.
identification
Small rockfish, reaching 30 cm, with spines on the head and fins, a family trait. It lives on soft bottoms, between 70 and 433 m, and depth is the best clue for telling it apart from shore rockfishes. The common name suggests a long, sharp spine.
where found
Lives in the eastern Pacific, from San Francisco, California, to Baja California, Mexico. In Latin America, it occurs only in Mexico.
Habitat: Soft bottoms, 70 to 433 m.
rules for the swordspine rockfish
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.
Bottom fish: it suffers barotrauma when brought up from great depth. Release it carefully and quickly.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01, b = 3.09; 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%.

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:
