Apri l'appDescrizione
Mugil brasiliensis, commonly known as Parati or Brazilian Mullet, is a species of ray-finned fish in the family Mugilidae. It is a commercially important fish in its native range, known for its adaptability to various aquatic environments, including marine, brackish, and freshwater habitats. This species plays a significant ecological role as a detritivore and herbivore, contributing to nutrient cycling in coastal ecosystems. It is characterized by its robust, fusiform body and distinctive coloration.

Consigli per l'identificazione
Body Shape and Coloration
Look for a robust, torpedo-shaped body with a dark greenish-gray back, silvery sides, and a white belly. Faint longitudinal stripes may be visible.
Adipose Eyelid
A prominent adipose eyelid covering a significant portion of the eye is a key characteristic of mullets, including M. brasiliensis.
Dorsal Fins
Two distinctly separate dorsal fins, with the first being spiny and the second soft-rayed, are typical for this species.
Pectoral Fin Length
The pectoral fins are relatively short and do not extend to the origin of the first dorsal fin, which helps differentiate it from some other mullet species.
Mouth
The small, terminal mouth with thick lips is adapted for bottom feeding.
Habitat
- Tipo di acqua
- brackish
- Profondità
- Typically found in shallow coastal waters, estuaries, lagoons, and lower reaches of rivers, usually from surface to about 20 meters.
- Ambiente
- Coastal marine waters, estuaries, lagoons, and freshwater rivers. Highly euryhaline, tolerating a wide range of salinities. Prefers muddy or sandy bottoms where it can forage for detritus and algae. Often found in schools.
- Areale geografico
- Western Atlantic Ocean, from the Caribbean Sea (including the Greater and Lesser Antilles) south along the coast of South America to Argentina. Also found along the coast of Brazil, where it is particularly abundant.
Informazioni sull'acquario
- Livello di cura: expert
- Temperamento: peaceful
- Dieta: filter_feeder
- Dimensione minima della vasca: 500 gallons
- Temperatura: 20-28°C (68-82°F)
- Livello di pH: 7.0-8.5
- Durezza: 10-25 dGH
- Compatibilità: Generally peaceful with other large, non-aggressive fish. Not suitable for typical home aquariums due to size and specialized feeding.
- Requisiti speciali: Requires very large tanks with excellent filtration to handle their detritivorous feeding habits. A sand or fine gravel substrate is essential for their foraging. Mimicking natural brackish or marine environments with appropriate salinity fluctuations is crucial for long-term health. Not commonly kept in aquaria due to size and specific needs.
Informazioni in natura
- Stato di conservazione: least concern
- Stagionalità: Spawning migrations typically occur during cooler months, often from late autumn to early spring, varying by geographic location. This influences fishing seasons and availability.
- Prezzo di mercato: Varies significantly by region and season, often moderate to high due to demand for fresh consumption and roe.
- Importanza commerciale: high
- Sapore: Mild, slightly oily, with a distinct 'fishy' flavor that is appreciated by many.
- Consistenza: Firm, flaky, and moist.

Fatti chiave
Euryhaline Adaptabilitybehavior
Mugil brasiliensis is highly euryhaline, meaning it can tolerate a wide range of salinities, allowing it to inhabit marine, brackish, and even freshwater environments.
Detritivorous Dietbehavior
This species primarily feeds on detritus, algae, and small invertebrates found in the substrate, playing a crucial role in nutrient cycling in coastal ecosystems.
Commercial Importanceinteresting
Parati is a significant commercial fish in South America, particularly valued for its flesh and roe, which is often processed into bottarga.
Spawning Migrationsbehavior
Adults undertake extensive spawning migrations from estuaries and coastal waters to offshore marine areas during specific seasons, often forming large schools.
Taxonomic Clarificationevolution
Historically, there has been confusion and misidentification between Mugil brasiliensis and Mugil liza (formerly M. platanus). Recent genetic and morphological studies have helped to clarify their distinct identities.

Specie simili
White Mullet
Mugil curema
Mugil curema generally has a more silvery body, often lacking the distinct longitudinal stripes of M. brasiliensis. Its pectoral fin typically reaches or extends beyond the origin of the first dorsal fin, unlike M. brasiliensis. The adipose eyelid is also less developed in M. curema.
Striped Mullet
Mugil cephalus
Mugil cephalus has more pronounced dark longitudinal stripes along its sides. Its pectoral fin is also shorter, not reaching the first dorsal fin origin, similar to M. brasiliensis, but the overall body shape and head profile can differ subtly. Genetic analysis is often required for definitive identification in areas of sympatry.
Lebranche Mullet
Mugil liza
Mugil liza (often confused with M. brasiliensis in some regions) typically has a more elongated body and a slightly different head profile. The number of scales in the lateral line and fin ray counts can also differ, though these require closer examination. Recent taxonomic revisions have clarified the distinction between M. liza and M. brasiliensis, with M. liza being the valid name for the species previously known as Mugil platanus.
