Lionfish

Pterois volitans; Pterois miles · Also called: red lionfish, devil firefish, Pez león

Protection: Invasive. DRNA allows lionfish fishing day and night, but spearing it on scuba, or in reserves and no-take zones, needs DRNA's written volunteer authorization.[1]

Facts

  • Zebra-striped in red and white, with long fin spines and long pectoral fin rays it spreads when hunting.[2]
  • Native to the Indo-Pacific and now invasive in Caribbean waters. It eats reef fish like snapper and grouper, has no known predators here and breeds all year.[3]
  • Spines on the back, belly and anal fins are venomous. A sting is very painful and is a medical emergency: get medical care.[2]
  • On a day you spear with that authorization, lionfish must be your only catch.[1]
