Combine the yoghurt, cayenne pepper, garlic, ginger, coriander, ground coriander, cumin, salt and turmeric in a resealable plastic bag. Close bag and mix everything together until evenly combined. Add the salmon and toss until well coated with the marinade; marinate overnight.
Preheat the grill. Lightly grease a baking tray.
Remove salmon from marinade and shake off excess; discard remaining marinade. Place onto prepared baking tray and grill until salmon flakes easily with a fork, 5 to 7 minutes per side.
