Season fish to taste and marinate in milk for 30 minutes. Add seasonings to flour. Towards end of 30 minutes melt 1/2 lb butter in frying pan on medium fire. Take fish out of marinade and dredge in seasoned flour before putting in frying pan.
Fry four fillets at a time, browning them on each side. Before cooking last four fillets add and melt rest of butter. Put fish in covered dish and place in warm oven. Save butter and put in separate dish until bottom of frying pan has been cleaned. Put butter back into frying pan and heat to saute onions, green onions and parsley. Saute until onions are soft and pour entire mixture over fish.
