Spiny Dogfish

Overview

The spiny dogfish is a small, abundant coastal shark that schools in enormous numbers along both coasts. Once dismissed as a bait-stealing nuisance, it is now recognized as fine table fare - sold as "rock salmon" in British fish-and-chip shops - and a fun, accessible light-tackle shark.

Identification

Spiny dogfish are slim gray sharks with white spots, no anal fin, and a sharp mild-venom spine in front of each dorsal fin - hence the name. They rarely exceed three to four feet.

Range & Habitat

They range along both US coasts over the continental shelf, schooling by season from nearshore shallows to deeper water, following cold water and bait.

Behavior & Diet

Dogfish travel in huge same-sex schools and feed voraciously on small fish, squid and crustaceans, often swarming a bait once one is hooked.

Best Seasons

Fishing is best when the schools move inshore - often spring and fall in the Northeast and cooler months elsewhere.

How to Catch Them

Bottom rigs with cut bait or squid over sand and structure; where dogfish school, catches come one after another.

Tackle & Rigs

Medium conventional or spinning gear, wire or heavy mono leader against their raspy skin and teeth, and simple bottom bait rigs.

Landing, Handling & Release

Handle carefully to avoid the two dorsal spines; use pliers and grip behind the head. Bleed and ice any fish you keep.

Table Quality

Properly bled and chilled, spiny dogfish is excellent - firm, mild and white - the traditional "rock salmon" of British fish-and-chips.

Common Mistakes

Getting jabbed by the dorsal spines and not bleeding the fish, which is essential for good flavor.

Regulations & Conservation

Dogfish are managed with commercial and recreational limits that vary by region. Always confirm the current state and federal regulations before keeping fish. We do not give legal advice.
