Simple Summary: This review paper aims to summarize, for the first time, the current state of knowledge on the potential value of the Integrated Multi-Trophic Aquaculture (IMTA) system to positively influence the zootechnical performance, animal welfare, and flesh nutritional quality of the co-cultivated species. The crucial role that the characteristic nutritional (i.e., greater availability of food and nutrients) and environmental factors (i.e., better water quality) of the IMTA system play in shaping the physiological responses of aquatic organisms produced at different trophic levels, i.e., growth, survival, stress responses, and welfare, is highlighted. Given the still-limited diffusion of this valuable fish farm system in many European areas, we believe that emphasizing the economic and market value of IMTA products could contribute to improve public perception and interest in the concrete adoption of IMTA on a commercial scale and constitute a basis to encourage further studies in order to explore new IMTA opportunities. IMTA is one of the most innovative and sustainable farming systems, exhibiting the best technique available in rearing aquatic organisms belonging to different positions along the trophic levels. In the literature and in legislation, the environmental benefits of IMTA protocols have been extensively recognized, mainly for its capability to reduce the ecological footprint of intensive aquaculture systems and concretely address the Sustainable Development Goal no. 14 (SDG 14). However, lesser attention is given to the assessments of its role in enhancing the zootechnical performance, animal welfare, and flesh quality of the species involved. To the best of our knowledge, this is the first review that aims to offer a systematic analysis of the existing literature on the main commercial motivations that could draw the attention of stakeholders, including consumers and fish farmers, towards a greater social acceptability and implementation of the IMTA system on a large scale. The findings suggest that, beyond its environmental advantages, IMTA systems can positively influence the productivity, growth, survival, feed efficiency, and animal health and welfare (AH&W), as well as the nutritional quality of the harvested species, thus offering significant economic and market value both in terms of Environmental, Societal and Governance (ESG) parameters and One Health.

This study aimed to improve postharvest management of flat oysters reared in a longline system in the mid Adriatic Sea, using short‐term storage and package in an innovative closed‐circuit system. For the trial, 870 oysters were employed, divided into three experimental groups (A, B, and C), N = 270 oysters each group, whereas the remaining 60 oysters were used for the 2 controls. Each group differed in relation to the time spent in the depuration tank and the time of packaging: group A was packed and immediately transferred to the cell; group B was depurated in a tank for 48 h, then packed and transferred to the cell; group C was depurated in a tank for 48 h and then packed, depurated for another 24 h and transferred to a cell. Samples of each group were sampled at different times of permanence in cell (t0) up until 12 days (t12) for biomorphometric, sensorial, nutritional, and microbiological analysis. Although the nutritional and sensorial quality of the oysters was more pronounced in group A, B and C groups also showed good results. In these two groups, thanks to the use of the modern water recirculation system the quality and safety of oysters was improved by reducing the presence of sludge and eliminating fecal contaminants completely than A treatment and seawater control. These results were also confirmed by the tank control, where a more extended depuration period positively influenced the same parameters emphasizing the importance of the adequate depuration processes in oyster production.

Simple Summary: In the rabbit species, the use of frozen semen could play a twofold role; on the one hand, it could bring many benefits to commercial breeding operations that rely on artificial insemination, and on the other hand, it would enable the conservation of biodiversity through the establishment of semen cryobanks. One of the less explored aspects of cryopreserving rabbit semen involves establishing the ideal sperm concentration in straws. Achieving this goal is crucial for minimizing the variability in outcomes and accurately determining the number of sperm delivered during artificial insemination procedures. This study sought to determine the ideal sperm concentration in straws for cryopreserving rabbit semen, with the broader goal of improving and standardizing the freezing protocol developed by our research group over the past decade. Our study provided a comprehensive analysis of how different sperm concentrations within straws (ranging from 15 to 75 million sperm) influenced the critical stages of the cryopreservation process, starting from initial dilution with the extender, through to cooling and equilibration, and culminating in the thawing phase. This investigation shed light on the role of the sperm concentration when determining the overall success of rabbit semen cryopreservation. This study aimed to investigate the impact of sperm concentrations on the in vitro quality of cryopreserved rabbit semen. The semen pools (n = 8, from 80 donors) were split into five aliquots with final sperm concentrations of 15, 25, 35, 55, and 75 × 106 per straw. The sperm motility parameters (CASA system) and membrane integrity (flow cytometric analysis) were both evaluated at various stages of the cryopreservation process: fresh semen dilution, cooling, equilibration, and immediately after and 30 min post-thawing. The results indicated the significant influence of the sperm concentration on the total motility (TM) and progressive motility (PM), with a consistent decline in all sperm variables over the time points. Notably, the semen with a final concentration of 15 × 106 exhibited a higher TM and PM after cooling and equilibration. The post-thawing quality (TM, PM) was higher (p < 0.05) in the mid-range sperm concentrations of 25 × 106 (49.9% and 19.7%) and 35 × 106 (46.2% and 19.7%) compared to the other concentrations. This study demonstrated that the sperm concentration per straw played a significant role in specific phases of the cryopreservation process. These findings contribute valuable insights for refining and standardizing the cryopreservation protocol for rabbit semen, emphasizing the importance of the sperm concentration. [ABSTRACT FROM AUTHOR]
