Mullet Fish: ID, Eating, Roe and Florida Bag Limits

A mullet is a silvery, torpedo-shaped fish of coastal and brackish water that feeds on detritus and is famous for leaping clear of the surface. The family, Mugilidae, has about 78 species in 26 genera, living in warm-temperate and tropical coastal waters worldwide, with a few in fresh water (Wikipedia).

In US waters the one most people mean is the striped mullet, Mugil cephalus, which the Florida Museum gives at up to 120 cm (47.2 in) and 8 kg (17.6 lb), ranging in the western Atlantic from Nova Scotia to Brazil, including the Gulf of Mexico.

How to recognise a mullet:

• Two separate dorsal fins (Wikipedia)
• Small, triangular mouth (Wikipedia)
• No lateral line along the side (Wikipedia)

Why do they jump? Wikipedia describes two kinds of leap: a fast escape jump, and a slower leap that ends in a splash and may help the fish take in oxygen through a special structure in its throat.

Florida anglers meet two common species, and the Florida Museum gives the one reliable check: the white mullet, Mugil curema, has scales running out onto its soft dorsal and anal fins, while the striped mullet does not.

Photograph the fish side-on with the fins spread so the fin bases are visible; that is the detail that settles it. FWC regulates striped, silver (white), fantail and redeye mullet under the same recreational rule, so the bag limit is the same either way.

Yes, especially fresh and in clean water. The Florida Museum says that along Florida's Gulf coast the striped mullet is regarded as an excellent food fish, and Wikipedia notes the flavour depends on the water it lived in: mullet from cleaner water taste better.

How it is eaten:

• Fried, smoked or baked, the common preparations Wikipedia lists
• Roe: salted, pressed and dried into bottarga in Italy, karasumi in Japan and avgotaraho in Greece (Wikipedia); the Florida Museum notes the roe sells at premium prices
• History: mullet has been food in the Mediterranean since Roman times, and ancient Egyptians ate a pickled, dried mullet called fesikh (Wikipedia)

Its reputation has swung. Wikipedia records that early American commercial fishers dismissed mullet, and that in the 1960s Florida officials tried to rebrand it as "lisa" to help sales.

Because mullet feed on bottom detritus, check your state's fish consumption advisory for the bay or river you fished before eating it often.

Because they rarely bite a baited hook. The Florida Museum describes striped mullet as daytime feeders on zooplankton, dead plant matter and detritus, so the worms, shrimp and lures that catch other inshore fish do not interest them.

That is why, as Wikipedia puts it, local fishermen usually catch mullet with a cast net. In Florida, FWC lists cast nets as legal gear along with hook and line, spears, gigs and seines, but spearfishing for mullet in fresh water is prohibited.

Mullet are also food for many other animals. The Florida Museum lists spotted seatrout, sharks, pelicans and other water birds, and dolphins among their predators.

FWC's recreational mullet rule, as checked on 25 September 2026, covers striped, silver or white, fantail and redeye mullet:

• Bag limit: 50 mullet per person per day
• Vessel limit: 50 per vessel from 1 September to 31 January; 100 per vessel from 1 February to 31 August
• Size limit: none
• Season: open all year
• Gear: cast net, hook and line, spear, gig or seine; no spearfishing for mullet in fresh water
• Local exceptions: stricter seasonal limits in parts of Pinellas County and night closures in parts of Charlotte County

The lower vessel limit from September to January overlaps the spawning season. The Florida Museum says adult striped mullet migrate far offshore in large schools to spawn in autumn and winter. Rules change, so check FWC before you go.

The flathead grey mullet is Mugil cephalus, the same species Americans call the striped mullet. Wikipedia lists its other names as black, bully, common, grey and sea mullet, and the 'flathead' refers to its flattened head. It is found in coastal tropical, subtropical and temperate waters of all seas, from about 62°N to 57°S (FishBase; Wikipedia), and it is euryhaline, able to live in fresh, brackish and salt water (Wikipedia).

Identification points beyond the ones above:

• Adipose eyelid: a well-developed clear fatty eyelid covers most of the pupil (FishBase)
• Stripes: dark lines along the upper sides formed by a dark spot at the centre of each scale (Florida Museum)
• Pectoral blotch: a large dark mark at the base of the pectoral fin (Florida Museum)
• Fins: first dorsal fin with 5 spines (FishBase); body stout and round in cross-section

Sources give different maximums:

• Florida Museum: 120 cm (47.2 in) and 8 kg (17.6 lb); lifespan 4 to 16 years
• Wikipedia: usually 30 to 75 cm, common around 50 cm, maximum 100 cm and 8 kg
• FishBase: 100 cm standard length, common 50 cm; a 12 kg maximum weight that it flags as needing confirmation; maximum age 16 years

Standard length stops at the base of the tail, so FishBase's 100 cm is a longer fish than a 100 cm total length. Most mullet caught are well under the maximum.

• Mercury: the FDA puts mullet in its Best Choices group, the lowest-mercury fish, 2 to 3 servings a week for adults (FDA, updated 5 March 2024). Local advisories still apply to fish from polluted bays
• Scale of the fishery: 125,000 tonnes reported worldwide in 2024, about 5% of it farmed (Wikipedia); FishBase lists it as highly commercial with a very high price category
• Status: Least Concern on the IUCN Red List, assessed May 2022, but FishBase rates its resilience as low, with a minimum population doubling time of 4.5 to 14 years
• Florida's fishery: FishSource profiles the Florida west coast cast-net fishery at about 3.5 thousand tonnes of catch, managed by Florida's Fish and Wildlife Research Institute; its most recent stock assessment, from 2014, treats the Atlantic and Gulf coasts as two separate units

Spawning, from the Florida Museum: in the Gulf of Mexico mullet have been seen spawning 65 to 80 km offshore over water deeper than 1,000 m; each female releases 0.5 to 2.0 million eggs, which hatch about 48 hours after fertilisation.

'Flathead' on its own, especially in Australia, means a different family: the Platycephalidae, bottom-dwelling fish with flattened, trowel-shaped heads and eyes on top (Wikipedia). Most are about 10 cm, but some Platycephalus species grow over 1 m. In Australia and Japan they are commonly caught on rod and line, the larger ones are treated as game fish, and there are active commercial fisheries for the family (Wikipedia). A flathead grey mullet is a mullet, not a flathead; check the head shape and the eyes, which sit on top of the head in true flatheads.
