Identification Tips

Bring an underwater fish ID card on every dive
Learn fish silhouettes, not just colors (colors change with depth)
Study size references before dives so you can estimate quickly
Ask Captain Dane—he can ID any reef fish instantly
Use an underwater camera to photograph and confirm ID later

Hunting Strategy by Depth

Shallow (15-30 ft): Permit, snapper schools, small grouper. Requires stealth and patience.

Mid-depth (30-50 ft): Red grouper, mutton snapper, mackerel. Best balance of visibility and target density.

Deep (50-80 ft): Large grouper, deep snappers. Requires excellent freediving skills and safety protocols.

Respect the Fish & Regulations

Know your limits before you hunt. Florida's FWC has strict size limits and bag limits for good reason—to protect reef ecosystems. Follow every rule, harvest only what you'll eat, and leave the reef healthier than you found it.
