Hygenic Dry Fish Preparartion

Introduction:

Drying is one of the safest means of preservation of fish. Many tribal communities of Assam prepare dry fish for their own consumption and surplus quantities are sold in nearby markets. Dry fish is popular among Bengali people, tribal communities and tea garden labours residing in the state. Dry fish prepared by different groups is mostly unhygienic with limited self-life and has failed to attract urban people. Following scientific methodologies, good quality dry fish can be produced which will definitely attract urban people in the state. Further there is a huge scope of exporting value added hygienic dry fish to the neighboring North-Eastern states as well as to the South-East Asian countries.

Steps of Hygienic Dry Fish Preparation:

ECONOMICS:

Annual variable recurring cost: 21x2700=56700.00

C) Annual investment:

D) Gross Income:

Sale of dry fish = 10 kgx21batches (drying yield approx. 33%)

@ Rs. 500.00 kg-1

F) Net Income (D –C) : Rs. 42800.00

At least 7 drying operations can be done in one month and in 3 months (from September to November) 21 such operation can be carried out.
