The directorate of fisheries is reportedly in the process of installing a solar-powered fish dryer at Old Goa. Dry fish is a delicacy in Goa and is much sought after during the monsoon season when there is a ban on fishing activities in the state.
Drying method is used to preserve the fish by removing moisture from them thereby arresting the growth of bacteria. Traditionally fishermen dry the surplus fish that is caught, in the open under the blazing sun. Air carries away the evaporated water from the fish body. The fishermen stand waving away flies hovering initially around the fresh fish, and turning the fish over so that both sides dry properly and get sterilized by the sun. However this must be considered as an unhygienic way to dry fish as the fish is subject to dust, insects, pests and microorganisms.
Hence drying the fish by using solar power is a step in the right direction as the dryer runs on the power of the sun generated through a solar panel. Several types of mechanically powered dryers have been developed and used commercially across the globe.
Properly handled and dried fish can last without spoilage between 6 to 12 months. It would be desirable to set-up solar-powered dryers at fishing jetties in the state.
