In this study, spiny dogfish fillets were soaked in 10% brine ( 1:2 w fillet/v solution) for 30 min. Then they were dipped in a solution containing 0. 1% ascorbic acid and 1.0% citric acid ( 1:2 w/v) for 5 min. All samples were covered with ice and stored at 3 IT for 12 days. Sensory, chemical, and bacteriological analyses were done in every 3 days. Sensory values were 3 and 5; pH values were 7.03 and 6.87; mesophilic aerobic bacteria counts were 5.77 and 5.56 for the control and treated samples, respectively, at the 12th day and these values were significantly (p < 0.05) different. Control samples were marketable on the 9th day and spoiled on the 12th day of storage while the treated samples were still marketable. It was seen that treatment of the spiny dogfish fillet with salt, ascorbic acid, citric acid increased the shelf life.
