Answer 1

After catching the fishes, fish spoilage is prevented by different preservation methods like:

1. Chilling with ice: It is a method of refrigeration. Due to the lowering of temperature, putrefaction is prevented and the quality of fish is maintained.
2. Freezing: Freezing of fishes helps to retain the natural appearance of fishes.
3. Freeze drying: Fishes are frozen and dried.
4. Smoke drying: This removes the moisture and prevents the growth of bacteria.
5. Sun-drying: Fishes are dried in sun to remove moisture.
6. Salting: By adding salt, dehydration takes place by osmosis.
7. Canning: Fishes are preserved in cans with salt or other artificial preservatives.
