Dogfish
Dogfish usually means small sharks such as spiny dogfish (Squalus acanthias) and related species sold as rock salmon, huss, or flake in some markets. The flesh is firm, mildly sweet, and holds together in batter and stews better than delicate white fish. It must be bled and iced promptly—urea can break down to ammonia if mishandled, giving a harsh smell. Classic British chip-shop rock salmon, Mediterranean stews, and smoked products use these economical sharks when stocks and regulations allow. Check local sustainability advice: some populations have been overfished. Skin is tough; fillets or steaks are the usual kitchen form. Cook through as for other firm fish, and reject any lot that smells of ammonia.

History
Coastal and river fishing for dogfish and related species supplied essential protein long before agriculture spread globally.
Salting, drying, smoking, and fermenting extended the shelf life of dogfish and enabled long-distance trade.
Ice preservation and railway transport brought fresh dogfish to inland cities beyond fishing ports.
Industrial freezing, aquaculture, and global logistics made dogfish widely available in international markets.
