On‐board Brazilian sardinella (Sardinella brasiliensis) conservation system based on cooling in ice, but in recent years, fishing boats have been applying immersion in chilled brine as a storage system on‐board. This study evaluated this system concerning physicochemical quality (total volatile bases, pH, histamine, moisture) of the fish and cation concentrations. Offshore (on‐board) data were collected (total storage time, over time temperature, fish mass captured by bid, load capacity in use and available) to assess the efficiency and viability. The results showed that this system is useful in maintaining the physicochemical quality of the fish since the samples met the quality standards required by law. Data showed high levels of sodium in fish muscle, which are strongly influenced by the immersion time, suggesting the need for standardization of the method considering the risks associated with consumption of foods with high levels of sodium.
