This week on your coast

Midsummer. Night and first-light tarpon. Mahi if the weed is in. Do not invent a bonefish morning in Condado.

Tarpon should be the day — Condado and the bay — urban tarpon, then the north drop if you switched to Offshore.

Midsummer. Night and first-light tarpon. Mahi if the weed is in. Do not invent a bonefish morning in Condado.

In peak this month

  • Tarpon

    Puerto Rico

    Keys migratory peak Apr–May. Boca Grande Pass is the spring stack. Jupiter inlet and beach. Texas beach/passes mid-summer. Venice south passes in the heat. Bahamas: resident fish in bights Apr–Oct.

  • Permit

    Puerto Rico

    None in Texas. Keys mecca — flats, banks, wrecks. Bahamas west sides May–Oct. Puerto Rico: east-island banks, not Condado. Seychelles 'permit' is often the Indo-Pacific fish (Trachinotus blochii) — same job, different ocean.

  • Hogfish

    Puerto Rico

    Keys and Caribbean patch reefs. Not a Texas bay fish. Not a bonefish headline. He lives on the hard bottom, not the grass.

  • Yellowtail snapper

    Puerto Rico

    Islamorada to Key West, then the Bahamas and the Spanish Virgins. Patch reefs and the first drop. Absent from Texas bays.

  • Mangrove / gray snapper

    Puerto Rico

    The snapper that will live in a Texas jetty and a Keys creek. Schoolies on structure. Bigger fish on the wrecks. Not a yellowtail.

  • Mutton snapper

    Puerto Rico

    Keys wrecks and Caribbean hard bottom. Not a Texas red. Not a yellowtail in a chum slick.

  • Lane snapper

    Puerto Rico

    Nearshore Gulf and Caribbean hard bottom. Texas jetties and the first reefs. Not the federal red-snapper story.

  • Black grouper

    Puerto Rico

    Keys, Bahamas, Yucatan, Puerto Rico wrecks. The heavy grouper. Do not print him on Galveston.

Noise, not the headline: Jack crevalle, Great barracuda.
