Abstract
Investigations were carried out on Effect of Different Open Sun Drying Methods and
Packaging on the quality of dry salted Lizard fish (Saurida tumbil) during the year
2018-19 at College of Fisheries, Junagadh Agricultural University, Veraval. Result of
Six months analysis indicate that drying and packaging method had more effect on
quality and shelf life of dry salted lizard fish. Rack dried (R1) with their treatments
D1 gunny bag, D2 200 LDPE air packaging, D3 200 LDPE vacuum packaging
(R1D1, R1D2, R1D3) and mat dried (M1) with their treatments M1D1, M1D2, M1D3
salted dried fish value of moisture, protein ash and total lipid as (R1) 18.62 ± 0.05 %,
56.35 ± 0.05 %, 19.44 ± 0.02 % , 5.48 ± 0.01%, (M1) exhibited 25.16 ± 0.02%, 53.13

cfu/g, in R1 and M1 respectively. (R1D3) was good in all treatment. Rack dried
sample was superior to mat dried and vacuum packaging is best than air packaging
and gunny bag in terms of all parameter. Dry fish marketing is the only employment
opportunity for local fisher women and it is a good source of protein for people in the
rural areas.
