everything about the grey tilefish
who is the grey tilefish
A tilefish of the family Latilidae, living on mud and gravel bottoms between 30 and 162 m, mostly caught between 75 and 200 m. It reaches 90 cm and up to 7 kg. It ranges from North Carolina to southern Florida, in the United States, and into Mexico, and also in the northern and probably eastern Gulf of Mexico. It mainly feeds on bottom invertebrates, such as crustaceans, mollusks, polychaetes and brittle stars (serpent stars), as well as fish. It is sold fresh and appears in both commercial and sport 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 grey tilefish; in the meantime, see the similar species.
identification
Spindle-shaped fish of normal body shape, from the family Latilidae, with the gray color that gives the species its name. It reaches 90 cm. It lives on mud and gravel bottoms, from 30 to 162 m, and is mostly caught between 75 and 200 m, a bit shallower than Caulolatilus cyanops, which is common between 150 and 250 m. This helps tell them apart on the bottom.
where found
In Latin America it occurs in Mexico and the Gulf of Mexico, on mud and gravel bottoms. Outside the region it ranges from North Carolina to southern Florida, in the United States.
Habitat: Mud and gravel bottoms, 30 to 162 m deep.
rules for the grey tilefish
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.
It has no dangerous spines, but it lives in deep water and bringing it up causes barotrauma. If released, do it carefully.
in the kitchen
It is sold fresh.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00646, b = 3.1; 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:
