Apri l'appDescrizione
Liza ramada, commonly known as the Thinlip Mullet, is a euryhaline fish belonging to the family Mugilidae. It is characterized by its elongated, fusiform body and relatively small mouth. This species is an important component of coastal and estuarine ecosystems, exhibiting an anadromous or catadromous migratory pattern depending on the specific population and environmental conditions. It is a schooling fish, often found in large aggregations.
Caratteristiche fisiche
- Forma del corpo
- elongated
- Colorazione
- Dorsal side is typically dark grey to greenish-brown, fading to silvery-white on the flanks and belly. Fins are generally dusky. No distinct dark spots or stripes on the body, which helps differentiate it from some other mullet species.
- Tipo di squame
- cycloid
- Posizione della bocca
- terminal
- Caratteristiche distintive
- Relatively small, thin lips, especially the upper lip, which is not thickened or fleshy., No adipose eyelid or only a very rudimentary one, not covering the pupil., Pectoral fin is relatively long, reaching or extending beyond the origin of the first dorsal fin., Scales on the head extend forward to the anterior nostrils., Typically 40-48 scales in the lateral line series.
- Pinna dorsale
- Two separate dorsal fins. The first dorsal fin has 4 strong spines. The second dorsal fin has 1 spine and 8-9 soft rays.
- Pinna caudale
- Moderately forked caudal fin.
- Pinna pettorale
- Long, reaching or extending beyond the origin of the first dorsal fin. Typically 15-17 rays.
- Pinne distintive
- Anal fin with 3 spines and 8-9 soft rays. Pelvic fins are subabdominal.
Consigli per l'identificazione
Lips
The most distinguishing feature is its thin upper lip, lacking the fleshy thickness seen in species like the Thicklip Mullet (Chelon labrosus).
Pectoral Fin Length
The pectoral fin is notably long, reaching or extending past the origin of the first dorsal fin.
Adipose Eyelid
Absence of a well-developed adipose eyelid, unlike the Flathead Grey Mullet (Mugil cephalus) which has a prominent one.
Coloration
Absence of distinct dark spots or stripes on the body, which can be present in other mullet species.
Habitat
- Tipo di acqua
- brackish
- Profondità
- Typically found in shallow coastal waters, estuaries, lagoons, and lower reaches of rivers, from surface to about 30 meters.
- Ambiente
- Euryhaline and diadromous, inhabiting marine, brackish, and freshwater environments. Prefers muddy or sandy bottoms where it can forage for detritus and small invertebrates. Often found in areas with seagrass beds or submerged vegetation.
- Areale geografico
- Eastern Atlantic Ocean, from the British Isles south to Senegal, including the Mediterranean Sea and the Black Sea. Also found in the Canary Islands and Madeira. Introduced to some other regions.
Informazioni sull'acquario
- Livello di cura: advanced
- Temperamento: peaceful
- Dieta: omnivore
- Dimensione minima della vasca: 500 gallons
- Temperatura: 10-24°C (50-75°F)
- Livello di pH: 7.0-8.5
- Durezza: 10-30 dGH
- Compatibilità: Generally compatible with other large, peaceful, euryhaline fish species. Avoid aggressive or overly territorial tank mates.
- Requisiti speciali: Requires a very large tank with ample swimming space and excellent filtration due to its size and schooling nature. A brackish to marine setup is often preferred, though they can adapt to freshwater. Live sand substrate and detritus for foraging are beneficial. Not typically kept in home aquaria due to size and specific environmental needs.
Informazioni in natura
- Stato di conservazione: least concern
- Stagionalità: Spawning typically occurs in marine waters during autumn and winter (October to February in the Mediterranean). Juveniles migrate to estuaries and coastal lagoons in spring and summer.
- Prezzo di mercato: Varies regionally, generally moderate.
- Importanza commerciale: medium
- Sapore: Mild, slightly earthy flavor.
- Consistenza: Firm, flaky white flesh.
- Metodi di cottura: Baked, Grilled, Fried, Smoked, Steamed
- Valore nutrizionale: Good source of protein, omega-3 fatty acids, and various vitamins and minerals.
Fatti chiave
Euryhaline Adaptabilitybehavior
Liza ramada is highly euryhaline, meaning it can tolerate a wide range of salinities, allowing it to move freely between marine, brackish, and freshwater environments.
Migratory Patternsbehavior
This species exhibits complex migratory patterns, often moving from freshwater or brackish feeding grounds to marine waters for spawning, and then juveniles returning to estuaries.
Detritivore Dietbehavior
Its diet primarily consists of detritus, algae, and small benthic invertebrates, playing an important role in nutrient cycling in its ecosystems.
Schooling Behaviorbehavior
Thinlip Mullets are typically found in large schools, especially during migrations, which provides protection from predators.
Taxonomic Reclassificationevolution
Historically, many mullet species were placed in the genus Mugil. Recent molecular studies have led to reclassification, with Liza ramada now firmly placed in the genus Liza.
