Typically, 70% of the fresh fish are taken for food - 20% of the fish are being sold in a dried form with or without salt - 5% of the fish which are damaged are used for cattle feed and a very negligible percentage of the fishes are goes for canning of export.
The most commonly used fish preserving techniques (traditional) are drying and salt curing. The open beach drying results in insects laying egg inside the fish that renders the product non-consumable.
This unhygienic drying cuts through the investment of the fishermen resulting in the loss of his meagre savings that drives him to absolute poverty.
Hygienic processing and value addition are two mantras for prosperity in the fish processing sector.
