The fixed-dose procedure , proposed in 1984, estimates a level of toxicity by feeding at defined doses and looking for signs of toxicity (without requiring death). [ 109 ]

Fish preservation is the method of increasing the shelf life of fish and other fish products by applying the principles of different branches of science in order to keep the fish, after it has landed, in a condition wholesome and fit for human consumption. [1][2] Ancient methods of preserving fish included drying, salting, pickling and smoking.
t. e.
