Florida and local context

REEF lists Alosa sapidissima in the cumulative diver-survey report for Blue Heron Bridge (WPB) Phil Foster Park. This is a cumulative volunteer report, not an independently reidentified voucher.

A documented past record does not establish present abundance or guarantee an encounter.

How to recognize this animal

A compressed silvery fish with a metallic blue-green back, a dark spot behind the gill cover and sometimes further spots along the side. The belly has a line of sharp-edged scales.

Size and life stages

The Smithsonian account reports 76 cm. It does not explicitly specify total, fork or standard length for this value; do not compare it directly with a length-labeled measurement.

Sources: Smithsonian STRI species account

Habitat and where to look

Coastal open water and freshwater or brackish spawning areas; reported at 0–100 m.

Sources: Smithsonian STRI species account

Range and local context

Canada to Florida. Historical corridor survey evidence is from Blue Heron Bridge (WPB) Phil Foster Park.

Feeding and diet

The species data report lists cephalopods, bottom-associated crustaceans, insects, bony fishes, animal plankton. These categories are not a local prey-frequency estimate.

Daily habits and behavior

During spawning, several males and a female swim close together and release eggs and sperm into open water, according to the U.S. Fish and Wildlife Service. Adults migrate into rivers to reproduce; a reef survey record does not document spawning there.

Mating and the next generation

The federal species account describes repeated broadcast-spawning events during the river migration. It distinguishes southern populations that die after their spawning season from northern populations that may return to sea and spawn again; this is not a site-specific survival forecast.

Look-alikes and identification traps

No species-level look-alike comparison has yet been verified for this draft. Use the diagnostic features above and retain uncertain photographs as unidentified rather than assigning a name from color alone.

Observe without disturbing

Maintain buoyancy and leave a clear retreat. Do not touch, chase, feed, uncover or move the animal, its shelter, or vegetation. Photographs are observations, not collection permission.

Rules unverified

Rule 68B-52.004 was amended effective November 4, 2026, confirmed by the official final-adoption notice. The associated proposal removes American Shad from the ten-fish aggregate and prohibits harvest, landing, possession, purchase, sale and exchange. The accessible official final-adoption page confirms the date but does not expose the adopted body; exact final text and adjacent federal treatment remain unverified.

This scoped status is not permission to collect or a guarantee of food safety.

Harvest, collection and food status

Checked 2026-11-11.

Harvest status

Rules unverified. Rule 68B-52.004 was amended effective November 4, 2026, confirmed by the official final-adoption notice. The associated proposal removes American Shad from the ten-fish aggregate and prohibits harvest, landing, possession, purchase, sale and exchange. The accessible official final-adoption page confirms the date but does not expose the adopted body; exact final text and adjacent federal treatment remain unverified. Do not rely on the older FWC freshwater ten-fish summary or retain this species on this profile’s authority. Obtain current FWC confirmation; the documented rulemaking is for catch-and-release only.

Jurisdiction and closed areas

Vero Beach–Key Largo Atlantic corridor. Florida state waters extend 3 nautical miles offshore; adjacent South Atlantic federal waters have separate rules. Park, sanctuary, method and landing restrictions remain applicable. No trip clearance. The mapped Blue Heron Bridge dive site is closed to marine-life collection, not automatically every form of fishing. Biscayne National Park prohibits ornamental collection without a superintendent collecting permit; mapped seasonal and permanent fishing closures also apply. John Pennekamp permits fishing only in designated areas, with additional collection prohibitions. Key Largo Management Area prohibits tropical-fish take and spearfishing, including equipment possession except uninterrupted passage. Sanctuary Preservation Areas, Ecological Reserves, Special-use Areas and posted access restrictions require exact boundary and exception checks. General species allowances do not override these restrictions.

Spearfishing

No spearfishing clearance. Florida’s shad gear framework is hook-and-line only, and the November 2026 amendment must be checked before any retention. No corridor-wide spearfishing clearance. FWC prohibits spearfishing in state-park waters, within specified distances of swimming beaches, fishing piers and fishing bridges, and in Upper Keys state waters from Long Key north to the Miami-Dade line. Key Largo Management Area has an independent federal spearfishing and equipment-possession restriction.

Food and menu status

Exact-species, capture-location food-safety advice was not verified. FDA market-group advice is not clearance for this individual local fish. Check current local fish-consumption advisories before eating any legally obtained fish. A dated exact-species local restaurant menu was not verified; menu status is unverified, not absent. Recipes are disabled.
