everything about the olive rockfish
who is the olive rockfish
Rockfish of the family Sebastidae, genus Sebastes. It grows to 61 cm and up to 1.6 kg. It lives in shallow water, mostly down to 30 m, on rocky reefs and near kelp forests, and there are records to 146 m. Sometimes it swims well off the bottom, in midwater. Juveniles are pelagic, and the species is viviparous, with planktonic larvae. It is considered a sport fish and is also kept in public aquariums.
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 olive rockfish; in the meantime, see the similar species.
fun facts
- Individuals up to 30 years old have been recorded.
identification
Rockfish with a fusiform, olive-toned body, as the common name suggests. It lives on shallow reefs and near kelp, sometimes well off the bottom, which sets it apart from deep-water rockfishes. Compare it with the kelp rockfish, which also lives in shallow kelp, but stays close to the bottom.
where found
Lives in the eastern Pacific, from northern California to Baja California, Mexico. In Latin America, it occurs only in Mexico.
Habitat: Shallow rocky reefs and kelp forests, usually down to 30 m.
rules for the olive 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.
Shallow-reef fish, no danger recorded. When hooked, remove the hook carefully and release the fish quickly.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00851, b = 3.05; 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:
