Cynoscion reticulatus, commonly known as Corvina or Reticulated Weakfish, is a species of marine fish belonging to the family Sciaenidae (drums and croakers). It is a commercially important species, particularly in its native range, known for its palatable flesh. This species is characterized by its elongated body, silvery coloration, and distinctive reticulated pattern on its upper flanks.
Physical Characteristics
- Body shape
- elongated
- Coloration
- Silvery overall, darker dorsally, fading to white ventrally. The upper flanks and back are marked with a distinctive pattern of dark, wavy lines or reticulations, which are more prominent in fresh specimens. Fins are typically dusky or yellowish.
- Scale type
- ctenoid
- Mouth position
- terminal
- Distinctive features
- Reticulated pattern on upper flanks, Two prominent canine-like teeth at the tip of the upper jaw, Large mouth extending to or beyond the posterior margin of the eye, Absence of barbels on the chin
- Dorsal fin
- Two dorsal fins; the first is spiny with 9-11 spines, and the second is soft-rayed with 1 spine and 20-24 soft rays. The two fins are distinctly separated.
- Tail fin
- Truncate to slightly emarginate caudal fin.
- Pectoral fin
- Relatively short, typically not reaching the anus.
- Distinctive fins
- Anal fin with 2 spines and 8-10 soft rays. Pelvic fins thoracic.
Identification Tips
Reticulated Pattern
Look for the characteristic dark, wavy lines forming a net-like pattern on the upper sides and back. This is the most reliable visual identifier.
Teeth
Examine the mouth for two prominent, canine-like teeth at the front of the upper jaw. This is a key feature of the genus Cynoscion.
Dorsal Fins
Note the two distinctly separated dorsal fins, with the first being spiny and the second soft-rayed.
Body Shape
Its elongated, somewhat compressed body shape is typical of weakfishes.
Habitat
- Water type
- saltwater
- Depth
- Typically found in shallow coastal waters, estuaries, and bays, ranging from the surf zone to depths of about 50 meters (164 feet).
- Environment
- Prefers sandy or muddy bottoms, often associated with seagrass beds, mangroves, and rocky reefs. Tolerant of varying salinities, frequently entering brackish waters.
- Geographic range
- Eastern Pacific Ocean, from the Gulf of California (Mexico) south along the coast of Central America to Peru.
Aquarium Information

- Temperament: semi-aggressive
- Diet: carnivore
- Minimum tank size: 500 gallons
- Temperature: 22-26°C (72-79°F)

- Hardness: 8-12 dKH
- Compatibility: Generally not suitable for home aquaria due to size and specialized needs. If attempted, only with very large, robust tankmates of similar size and temperament.
- Special requirements: Requires a very large tank with ample swimming space, excellent filtration, and a diet of fresh, high-quality marine proteins. Not typically kept in home aquariums.
Wild Information
- Conservation status: least concern
- Seasonality: Spawning typically occurs during warmer months, leading to increased catches. Availability can vary seasonally based on migratory patterns and fishing regulations.
- Market price: Varies significantly by region and season, often considered a premium whitefish.
- Commercial importance: high
- Taste: Mild, sweet, and delicate
- Texture: Flaky, firm, and moist
- Cooking methods: Baking, Grilling, Frying, Steaming, Sautéing
- Nutritional value: Excellent source of lean protein, omega-3 fatty acids, and various vitamins and minerals.
Key Facts
Drumming Soundsbehavior
Like many members of the Sciaenidae family, Corvina (Cynoscion reticulatus) can produce drumming or croaking sounds using specialized muscles vibrating against their swim bladder. These sounds are often associated with spawning or territorial displays.
Top Predatorbehavior
Cynoscion reticulatus is an active piscivore, meaning it primarily preys on other fish. It plays an important role as a top predator in its coastal ecosystems.
Rapid Growthinteresting
This species exhibits relatively rapid growth, reaching marketable size within a few years, which contributes to its commercial importance.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: edible
- Handling notes: No specific handling precautions beyond standard fish handling to avoid fin spines. The teeth, while prominent, are not venomous but can cause minor cuts if not handled carefully.
Similar Species
Orange Mouth Corvina
Cynoscion xanthulus
C. xanthulus typically has a more yellowish or orange coloration inside the mouth and gill covers, and generally lacks the distinct reticulated pattern of C. reticulatus. Its geographic range overlaps but C. xanthulus is more prevalent in the northern Gulf of California.
White Seabass
Atractoscion nobilis
While also a large sciaenid, A. nobilis has a more robust body, lacks the prominent reticulated pattern, and has a more uniform silvery-gray coloration. Its geographic range is primarily California to Baja California.
Shortfin Corvina
Cynoscion parvipinnis
C. parvipinnis has shorter pectoral fins and a less pronounced reticulated pattern, often appearing as faint spots or blotches rather than distinct lines. Its range is also more restricted to the northern Pacific coast of Mexico and California.
