everything about the pluma porgy
who is the pluma porgy
The peixe-pena is a sparid of the family of the sargos and the red porgy, living in the western Atlantic from the Bahamas to Brazil, in the southern Gulf of Mexico and throughout the Caribbean, where it is the most common species of its genus. Adults are found over rock bottoms and reefs, but also on flat bottoms down to 85 m, usually from 5 to 30 m; juveniles stay in shallower water. With strong teeth, it eats crabs, hermit crabs, mollusks, worms and brittle stars. It is an important table fish in the Caribbean. In Brazil it has been recorded on deep reefs of the Northeast. In recreational fishing it is caught on natural bait on the bottom, on a small hook, and it fights well for its size.
fun facts
- It is the most common species of its genus in the Antilles.
- It eats even brittle stars, relatives of sea stars.
identification
Deep-bodied and compressed, silvery with a lilac sheen; the edges of the scales are yellowish brown and the center of each scale has a vertical blue or blue-green mark. Head profile moderately sloped. Other Calamus species in Brazil are very similar and require attention to color details. The sargo-de-dente has wide black bars; the red porgy is pink.
where found
From the Bahamas to Brazil, in the southern Gulf of Mexico and throughout the Caribbean. In Brazil there are records on deep reefs of the Northeast.
Habitat: Rock bottoms and reefs, as well as flat sandy bottoms; juveniles in shallower waters.

when to fish
best season
Found year-round; in the Caribbean it is caught in any month.
best time of day
Daytime. Feeds by day, rooting the bottom for crabs and shells.
what affects the pluma porgy
sensitivity The little bars show how much each factor affects this species. Five full: it feels it a lot.
cold and cold fronts
A warm-water fish; activity drops in cold water.
atmospheric pressure
A churned sea after a cold front shuts down bottom fishing.
moon
Small effect.
rain
Little effect.
water level
Not applicable at sea.
noise
Moderately wary.
wind
Strong wind makes it hard to keep the bait still on the bottom.
tide
Weak to moderate current makes bottom fishing easier.
depth
Usually 5 to 30 m.

tip from an angler
A small bait tied well to the hook: with its strong mouth and crushing teeth, it steals soft bait.
rules for the pluma porgy
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
Conservation: Not on the national list (Portaria GM/MMA 1.667/2026). We found no specific federal rule for this species.
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.
Remove the hook with pliers and release quickly; it is a tough fish and returns well to the bottom.
in the kitchen
White, tasty flesh, good fried or baked. Ciguatera has been recorded in the Caribbean.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.0195, b = 2.93; FishBase (estimativa bayesiana para o gênero e o formato do corpo, comprimento total)). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
The season weights (months), the time of day and the sensitivities (cold, pressure, moon, wind, rain, tide, strong light, murky water and noise) are the app's editorial estimates, based on the literature below and on the field experience of anglers and guides. They are not official data nor a measurement made for this species, and they may vary by region and year. Closed seasons and legal rules appear in the rules section, with the norm and a link.

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:
