everything about the little gulper shark
who is the little gulper shark
The little gulper shark is a deep-water shark of the family Centrophoridae, small and slender, with a long, narrow snout. It reaches 110 cm and weighs up to 7.3 kg. It lives near the bottom of the outer shelf and upper slope, usually below 200 m, and goes down to 1,400 m. It feeds on bony fish and squid. It is ovoviviparous, usually with one pup per litter, born at 40 to 50 cm. It turns up in commercial fishing, in a minor way, and is also of interest to recreational fishing. There are no records in Brazil.
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 little gulper shark.
fun facts
- Males mature at around 80 cm.
identification
Small slender shark with a long, narrow snout. The first dorsal fin is short and the second is tall, and the tips of the pectoral fins are quite long. The back is brownish grey and the belly is light grey. It lives at depths greater than 200 m, on the outer shelf and slope.
where found
Western Atlantic, with records in Cuba, Mexico, Colombia and the Guianas. No records in Brazil.
Habitat: Bottom of the outer shelf and upper slope, usually below 200 meters deep.
rules for the little gulper shark
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.
Deep-bottom shark: release it with minimal handling and without keeping it out of water for long. The dorsal fins have spines, so hold it with care.
in the kitchen
Its flesh is sold dried and salted for human food.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00245, b = 3.18; 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:
