Abstract: Bycatches were dried unhygenically and transported to other states for poultry feed from Tuticorin
coast. There are more than 25 species of bycatches are used for sun drying for poultry feed. Feed farmers
purchase low cost trash fishes discarded in the fish landing regions for poultry feed preparation and transfer
it through unhygienically in trucks to the local drying area. Fishes were dried on sandy floor without washing,
degutting, salting and implementing any hygienic measures to avoid the intact of natural contaminants like
insects or dust. The semi-dried fishes were packed in gunny packs and taken to dry fish wholesale market by
the dry fish farmers or other middlemen involved in dry fish marketing. The chemical composition and qualities
such as moisture, protein, lipid, ash, peroxide value, total volatile base nitrogen content and microbiological
properties were analyzed. Moisture content was above the acceptable limit in 18 species of fishes. Protein and
lipid content of dried fish samples was lower with the range of 4.85 to 11. 20% and 0.02 - 1.88%, respectively.
Ash content was found to be highest in all the fish samples (10.91 - 25.02%). Peroxide and Total Volatile Basic
Nitrogen (TVB-N)value of the fish samples were found above the acceptable limit of 10 - 20meq/kg of fat and
up to 30 mg/100g, respectively. Bacterial count was found higher, however Salmonella and Coliform was found
in most of the dried fish samples. Organoleptic quality of the dried fish samples was found very bad with
objectionable flavor, odor and insect infestations. Extension work are needed to develop hygienically dried
fishes with good nutritive value improve economic value in commercialized markets.

Fish is an extremely perishable food item and require consumption but also used in other commercial small
preservation. Several methods are followed over the world scale industries like aqua feed and poultry feed
for preserving fish to extend its shelf life including drying, preparations [4]. Sun drying of fishes for human
