Spiny Dogfish: Facts, Records, and How to Catch Them | FishyAF
What is a Spiny Dogfish?
The Spiny Dogfish is a tough, schooling coastal shark with two sharp dorsal spines and endless cardio. Common across the North Atlantic, they mob bait balls, vacuum squid strips, and will test your patience and your leader. Small? Sure. Relentless? Absolutely.
The first FishyAF Dogfish was landed by Mike Valenzo — textbook tide, steady tap-tap, and a shark with an attitude bigger than its weight class.
