Mugil cephalus, commonly known as the Flathead Grey Mullet or Kefal, is a euryhaline and catadromous fish species found in coastal tropical and subtropical waters worldwide. It is characterized by its robust, cylindrical body, flattened head, and distinctive adipose eyelid. This species is highly adaptable, inhabiting a wide range of environments from marine to freshwater, and is of significant commercial importance globally.

Tanımlama İpuçları
Adipose Eyelid
The most distinguishing feature is the prominent, fatty eyelid that covers much of the eye, leaving only a vertical slit for the pupil. This is a key differentiator from many other fish species.
Dorsal Fins
Two distinctly separate dorsal fins. The first is short and spiny (4 spines), while the second is longer and soft-rayed. This separation is characteristic of mullets.
Head Shape
The head is noticeably broad and flattened on top, giving it the 'flathead' moniker.
Coloration and Stripes
Silvery body with a darker back and often faint, horizontal dark stripes along the sides, especially visible in fresh specimens.
Yaşam Alanı
- Su tipi
- brackish
- Derinlik
- Typically found in shallow coastal waters, estuaries, lagoons, and even penetrates far into freshwater rivers. Usually found from the surface down to about 120 meters (400 feet), but most commonly in the upper 20 meters.
- Ortam
- Highly adaptable, inhabiting marine, brackish, and freshwater environments. Prefers sandy or muddy bottoms where it can feed on detritus and algae. Often found in schools, especially during migrations.
- Coğrafi dağılım
- Circumglobal in tropical and subtropical waters. Found in the Atlantic, Pacific, and Indian Oceans, including the Mediterranean Sea, Black Sea, Gulf of Mexico, and Indo-Pacific region. Its range extends from temperate zones to the tropics.
Akvaryum Bilgileri
- Bakım seviyesi: advanced
- Mizaç: peaceful
- Beslenme: filter_feeder
- Minimum tank boyutu: 500 gallons (for adults)
- Sıcaklık: 18-28°C (64-82°F)
- pH seviyesi: 7.0-8.5
- Sertlik: 10-25 dGH
- Uyumluluk: Generally peaceful with other large, non-aggressive fish. Best kept in species-specific tanks or very large community tanks with similar sized, robust species. Avoid small or delicate tank mates.
- Özel gereksinimler: Requires very large tanks with excellent filtration due to their size and feeding habits. A sandy or silty substrate is preferred as they are bottom feeders. Good water circulation and oxygenation are crucial. Not typically suited for home aquaria due to their size and specific dietary needs; more common in public aquariums or aquaculture settings.
Doğal Yaşam Bilgileri
- Koruma durumu: least concern
- Mevsimsellik: Spawning typically occurs offshore in cooler months (autumn to winter in temperate regions, year-round in tropical areas). Availability in markets can vary seasonally, with peak catches often coinciding with spawning migrations.
- Piyasa fiyatı: Varies significantly by region and market demand, often moderate to high due to its culinary versatility and roe (bottarga).
- Ticari önem: high
- Tat: Mild, slightly oily, and distinctively 'fishy' flavor, which can be polarizing. The flavor is influenced by its diet and habitat.
- Doku: Firm, flaky, and somewhat coarse flesh. Contains small bones.
- Pişirme yöntemleri: Grilling, Baking, Frying, Smoking, Steaming, Used for roe (bottarga)
- Besin değeri: Good source of protein, Omega-3 fatty acids, and various vitamins and minerals (e.g., B vitamins, selenium).
Temel Bilgiler
Global Distributionamazing
Mugil cephalus is one of the most widely distributed fish species in the world, found in tropical and subtropical coastal waters across all major oceans.
Euryhaline Naturebehavior
This species is highly euryhaline, meaning it can tolerate a wide range of salinities, allowing it to move freely between marine, brackish, and even freshwater environments.
Detritivore Dietbehavior
Kefal are primarily detritivores and herbivores, feeding on detritus, algae, diatoms, and small invertebrates found in the substrate. They use their gizzard-like stomach to grind food.
Bottarga Sourceinteresting
The roe (eggs) of Mugil cephalus is highly prized in many cultures, particularly in the Mediterranean and Asia, where it is cured and pressed to produce a delicacy known as 'bottarga' or 'karasumi'.
Leaping Behaviorbehavior
Mullets are known for their characteristic leaping behavior, often jumping clear out of the water. The exact reason is debated but may be related to avoiding predators, dislodging parasites, or obtaining oxygen.
Catadromous Migrationsbehavior
While not as pronounced as eels, Mugil cephalus exhibits catadromous tendencies, migrating from freshwater or brackish feeding grounds to offshore marine waters to spawn.
Güvenlik Bilgileri
Güvenli- Güvenlik seviyesi: safe
- Zehirli: Hayır
- Yenilebilirlik: edible
- Tutma notları: Mugil cephalus is not venomous and poses no significant handling risks. Its scales can be somewhat abrasive, so standard fish handling precautions (e.g., gloves) are advisable to prevent minor scrapes. They can be quite slippery and active when caught.
Benzer Türler
Thinlip Mullet
Liza ramada
Liza ramada has thinner lips and lacks the prominent adipose eyelid of Mugil cephalus. Its pectoral fin is also longer, reaching past the eye when folded forward.
Thicklip Mullet
Chelon labrosus
Chelon labrosus has noticeably thicker lips, especially the upper lip, and a less developed adipose eyelid compared to Mugil cephalus. It also typically has fewer lateral stripes.
Golden Grey Mullet
Liza aurata
Liza aurata is distinguished by a prominent golden spot on the operculum (gill cover) and a less developed adipose eyelid. Its body is generally more slender.
