On the background of the growing need for natural alternatives to fresh fish preservatives, the present study is focused on the assessment of Nigella sativa seed oil effect over the freshness and morphological structure of Carassius gibelio (Prussian carp) muscle tissue, during typical cold storage. The monitoring involved storage of fish samples at regular temperature conditions, recommended for the food industry (0 ± 1°C, on ice). The Carassius gibelio fish samples were divided into three groups: control group (C), without NSSO; test group 1, fortified with 0.1% v/w NSSO (T1) and test group 2, fortified with 0.6% v/w NSSO (T2). Histological and freshness monitoring reveal that treatment groups T1-T2 keep normal morphological structure of fish muscle throughout the monitoring period, while showing slightly improved freshness indicators (pH and TVB-N), compared to control samples. This study strengthens the proposal for NSSO as a natural enhancer of fresh fish quality and shelf life.
