Harvest, protection and eating safety

Can it be hunted or harvested?

Pomacentridae damselfish; listed marine-life family. Where collection is lawful, land and maintain alive using adequate life support. Daily limit: five of a species within 20 organisms; two-day possession: ten of a species within 40 organisms. Recreational sale prohibited; license and allowed nonlethal gear rules apply.

Florida seasons and areas

No affirmative year-round food-harvest or seasonal clearance assigned. FWC marine-life requirements also apply in federal waters. Check mapped boundaries before any take. Blue Heron Bridge prohibits marine-life collection within the designated dive-site area, not all county fishing. Biscayne prohibits ornamental collection without a superintendent permit and has a mapped March 1–May 31 fishing/possession closure, effective March 2026, with properly stowed continuous transit excepted. Pennekamp prohibits tropical-fish collection and spearfishing. Key Largo Management Area prohibits taking tropical fish and marine invertebrates; the latter exceptions are commercial spiny-lobster/stone-crab trapping and recreational spiny-lobster hand/hand-gear take under applicable rules, not recreational crab collection. It separately prohibits spearfishing. Sanctuary Preservation Areas prohibit fishing and collection subject only to expressly stated exceptions. These are site restrictions, not a corridor-wide fishing ban.

Can it be speared?

Do not spear a live-only collection species. FWC allows specified nonlethal methods; no quinaldine. FWC restricts spearfishing near public swimming beaches, fishing piers/bridges, jetties and in state parks. The Long Key-north Monroe restriction concerns state waters; Key Largo Management Area has a separate prohibition. Federal location alone is not clearance.

Is it safe to eat?

Live-only collection is not recreational food harvest. No species/site-specific food-safety clearance or meal frequency was established. Legal harvest does not mean safe to eat; some marine toxins survive cooking and freezing. Consult current Florida Health guidance and local advisories. No dated, species-matched local menu evidence was verified; recipes remain disabled.

Pomacentridae damselfish; listed marine-life family.

This review covers the Vero Beach–Key Largo Atlantic corridor: Indian River, St. Lucie, Martin, Palm Beach, Broward, Miami-Dade and Monroe counties. Florida Atlantic state waters and South Atlantic federal waters are distinct jurisdictions. Do not extend a state-water season tag to federal waters or transfer Atlantic rules to Gulf-side Keys waters. Park and sanctuary boundaries can override a species allowance.

Before you act: Confirm the species, date, exact management area, state or federal waters, gear, licenses and current local closures. A local occurrence record never grants permission to take an animal.

Identification and source cautions

• Historical cumulative citizen-science occurrence is not an independently reidentified voucher or a current encounter probability.
• Regional depths and range do not establish presence at every corridor site.
• Reported maximum is source-specific, not a typical local sighting size.
• Database lists both no pelagic phase and pelagic larvae; do not reproduce these as compatible established facts.
