Freshwater Mussel Pasta: Foraging the River for the Table

The Species and Where to Find Them

The freshwater mussel most commonly encountered in southern Australian rivers is Velesunio ambiguus and related species — large, dark-shelled bivalves found half-buried in sandy and gravelly river bottoms in clean, well-oxygenated water. They are typically 5–10cm long and found in clusters in riffles and runs, often visible from the bank in clear water.

Collection for personal consumption is legal in most states but check local regulations, as some species are protected in certain catchments. Do not collect from water with known pollution issues or agricultural runoff.

Preparation

Freshwater mussels require more preparation than their marine counterparts. Purge them for at least 24 hours in clean, cold, well-oxygenated water — change the water twice. They will expel significant quantities of grit and silt. After purging, scrub the shells under cold water. Discard any that are open and do not close when tapped.

Pasta Recipe (serves 2)

1. Heat 2 tablespoons of olive oil in a wide pan over high heat. Add 2 cloves of crushed garlic and cook for 30 seconds.
2. Add the mussels and 150ml dry white wine. Cover tightly and cook over high heat for 5–6 minutes until shells open. Shake the pan twice during cooking. Discard any that remain closed.
3. Remove mussels from pan. Reduce the cooking liquid by half — this is the sauce base. Add butter and swirl to emulsify. Season carefully (the mussels and their liquid are naturally salty).
4. Remove mussels from shells, reserving a few in-shell for presentation. Add mussels to the sauce with fresh parsley and cooked spaghetti or linguine. Toss to combine.

Serve immediately — mussels toughen if they sit in heat. The flavour is cleaner and more delicate than marine mussels with a distinct freshwater character that is worth experiencing. Gather them on your next river trip and browse our river fishing and wading range.
