No matter where gilthead sea bream are farmed – whether in marine cages or earthen ponds – the nutritional profile consistently shows these fish are rich in essential fatty acids and amino acids, both vital components for human health.

A study led by researchers from Istanbul University and Bartin University, in Türkiye, has demonstrated the potential of both farming systems to produce high-quality fish.

The research focused on seasonal changes, analysing fish raised in summer and winter. Published in the scientific journal Aquaculture International, the findings reveal that marine cages outperform earthen ponds in terms of omega-3 fatty acids, particularly EPA and DHA, which support heart and brain health. Meanwhile, fish from earthen ponds displayed higher lipid content, offering a practical option for aquaculture in areas unsuitable for conventional agriculture.

With Turkey already recognised as the world’s leading producer of gilthead sea bream, the study highlights the nation’s potential to further expand and diversify its aquaculture industry. Over 1,800 enterprises in the region operate using earthen ponds, showcasing the feasibility of low-salinity systems for sustainable fish farming.

Fish are a vital source of protein, and with global seafood demand on the rise, sustainable aquaculture practices are becoming increasingly important. The study emphasises that gilthead sea bream cultivated in these systems not only meet but exceed nutritional expectations.

Moreover, the research identified seasonal differences: fish farmed in winter contained higher protein levels, attributed to their slower metabolism during colder months. This seasonal advantage presents an opportunity to refine farming strategies for optimised production.

While the study lays a robust groundwork, the researchers stress the importance of further investigation into the flavour and sensory qualities of gilthead sea bream. These characteristics, alongside nutritional value, are key to securing consumer appeal and commercial success.
