parassi mullet
Mugil incilis · Mugilidae · omnivore
Mullet of estuaries and brackish waters of the Caribbean and northern South America, down to southeastern Brazil. It is of more interest to small-scale commercial fishing than to rod fishing.

everything about the parassi mullet
who is the parassi mullet
Mullet of the family Mugilidae, with a fusiform body, living mostly in estuaries and brackish waters, but also entering the sea and hypersaline waters. It reaches 40 cm. To spawn, adults gather in small groups at the mouths of rivers and coastal streams early in the year. The female lays millions of large, yolk-rich eggs that are pelagic. Juveniles travel long distances up swamps and coastal rivers in search of food and shelter. It has little commercial use, is sold fresh or salted, and salted dried roe is considered a delicacy.
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 parassi mullet; in the meantime, see the similar species.
identification
Mullet with the typical spindle-shaped body of its group. The popular name tainha-olho-de-amarelho suggests its yellowish eye. Males reach 40 cm and females 35 cm. Habitat also sets this species apart: it lives mostly in estuaries and brackish waters, more than in the open sea.
where found
It occurs in the Caribbean and on the northern coast of South America, from the Guianas and Trinidad and Tobago to southeastern Brazil, in estuaries and brackish waters.
Habitat: Estuaries and brackish waters, sometimes in marine and hypersaline areas.

rules for the parassi mullet
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 Brazilian national list (Ministerial Ordinance GM/MMA No. 1.667/2026).
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. Hold it with wet hands and release it promptly.
in the kitchen
Sold fresh or salted, and the roe, salted and dried, is considered a delicacy.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00977, b = 2.91; 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:
