Saltwater · Year-round in deep water when seas allow; best late spring through fall
Snowy Grouper
Hyporthodus niveatus
A deep-drop favourite of the US South Atlantic, named for the white snowflake spots scattered over its dark body — markings that fade in the biggest adults. It lives far deeper than most groupers, so reaching it takes heavy tackle and calm weather, and strict quotas apply, so always check the current rules before a trip.
Seasons · Peak
Identifying features
- White snowflake-like spots in rows over a dark brown to grey body
- Spots fade with age — very large adults can look almost plain dark
- Deep, stout body with a steep head and large eyes suited to deep water
- Juveniles show a dark saddle blotch below the soft dorsal fin
- Spinous dorsal fin edged dark, with pale spotting continuing onto the fins
Habits
- A solitary deep-slope fish holding over rock, ridges and ledges
- Feeds on fish, squid, crabs and other deep-bottom prey
- Slow-growing and very long-lived, which makes large fish valuable breeders
- Females change sex to male with age, as in other groupers
- Juveniles live much shallower than adults and move deeper as they grow
Distribution
Where to find them
- Deep shelf-edge ledges off the Carolinas, its prime US ground
- Offshore humps and deep breaks off Florida's Atlantic coast
- Deep rocky slopes off the Florida Keys and in the northern Gulf off Louisiana
Where they live
How to catch them
Electric-reel deep dropping Boat
Rig: Electric reel on a stout deep-drop rod, multi-hook chicken rig with 12/0-14/0 circle hooks, 3-5 lb sinker and a light stick, fished in 600-1000+ ft (180-300+ m)
Bait/lure: Cut bait — mullet, bonito or squid
Key tip: Fish small humps and ledge edges, keep the rig on the bottom, and check the current quota before keeping any fish.
Manual deep-drop rigs on offshore humps Boat
Rig: Heavy hand-crank reel, stout rod and a two-hook deep-drop rig with whole squid over offshore humps and ridges
Bait/lure: Whole squid
Key tip: Work the up-current edge of the hump and wind steadily once hooked — stopping lets a grouper reach the rocks.
