Special Issue Information

Dear Colleagues,

Scientific research was greatly challenged by the COVID-19 pandemic, which pressured research institutes to challenge themselves to give a quick answer to the worldwide humanitarian urgent situation. When it began to lighten, a conflict erupted in Europe, casting a shadow over future stability. This unpredictable situation triggered a global energy and food crisis, amplifiying the urgent need to invest in food systems to ensure that they can provide safe, affordable, nutritious and healthy food for an expanding global population. Aquatic products have gained recognition as vital components of these systems. In 2020, their contribution was more than 60 percent higher than the average in the 1990s, a rise primarily attributed to increased aquaculture production. However, despite considerable advances in marine aquaculture, significant challenges remain, including species diversification, disease management and biosecurity, enhancing growth efficiency, addressing climate change impacts, finding alternatives to fishmeal and oil, conserving natural resources, and reducing the environmental footprint. Consequently, research in marine aquaculture is vital and requires an integrated approach to develop and strengthen the sector to meet the growing global demand for aquatic products.

The swimbladder, when present, is the main contributor to the acoustical target strength (TS) of fish. Numerical modeling of target strength must include swimbladder dimensions, orientation, and shape for the proper estimation of target strength and its directivity. Several Atlantic Bluefin tuna (Thunnus thynnus, ABFT) specimens between 90 and 100 cm of fork length were studied by performing computed tomographic (CT) post-mortems in both fresh and frozen states. ABFT swimbladder 3D models were derived for the first time to be compared with experimental TS measurements through numerical simulation methods, using the Method of Fundamental Solutions (MFS). The numerical estimation (−23.3 dB) agreed with the experimental measurement of TS (−22.1 dB) performed in a tank with tuna with a mean fork length of 100 cm, showing the importance of considering realistic swimbladder shapes and swimming behavior in the numerical simulation of TS.
