Dry Fish Worker
Dried Fish edible fishes preserved through removal of moisture. Fish drying as a means of preservation has been practiced since time immemorial in this region, and dry fish is considered as a delicacy in the menu of many people of Bangladesh. The basic principle of fish drying is that the activity of the muscle enzyme and microorganism is reduced to a minimum through drawing out the water content of the fish by sun drying in a traditional way. Fish drying is carried out in some selected coastal areas and inland depressions of Bangladesh where modern preservation facilities and good infrastructure for transportation are absent. Some important spots are: Dublar Char of sundarbans, st martin's island, Rangabali, Sonadia Island, Moheshkhali, Cox's Bazar, Chittagong, lbrahimpur of Sunamganj, and Joshomantapur of Jamalganj. Estuarine and marine set bag nets (Behundi) are the main gears for supplying fishes for drying; harvested fishes are carried to the drying yards and then segregated species-wise by hired labourer.
The important marine and freshwater species that are dried are Loitya (Harpodon neherius), Chhuri (Lepturacanthus savala), Punti (Puntius sarana, P. stigma), chapila (Gadusia chapra), Lakhua (Polynemus indicus), Rupchanda (Pampus chinensis), and shrimps (Metapenaeus species and Penaeus species).
Two to eight days are required for drying depending on the size and species of the fishes. The segregated fishes are placed on mats, or hung from raised racks/poles. The dry fishes are often infested by blow fly (Chrysomya species) and their larvae (maggot) during the drying phase, especially in the cloudy and rainy days; and by beetle (Necrobia species) and mites in the store causing considerable amount of weight loss of the finished product every year. To protect the products from the infestation of insects, the merchants often use various harmful insecticides and fungicides. But the availability of sterilization of dried fishes by radiation can ensure pollution-free environment. Institute of Food and Radiation Biology of Bangladesh Atomic Energy Commission is currently engaged in research on storage technology of dried fishes using nuclear radiation.
