The common octopus () is a promising candidate for aquaculture diversification, particularly in Europe. As interest in octopus farming grows, animal welfare concerns arise. In bony vertebrates (teleosts and tetrapods), measurements of the levels of corticosterone or cortisol have been successfully used as indicators of stress and welfare.

- The study investigated the impact of mutation accumulation (MA) over 255 generations on the viability of Drosophila melanogaster, using distinct MA lines and control groups.
- After expanding an MA line to form new lines, the decline in viability in the new MA2 lines was found to be 2.5 times greater than in the original MA1 lines, indicating more severe mutational effects over time.
- Additionally, the inbreeding depression and additive variance for certain traits in the control group from MA2 were significantly higher than the original group, suggesting a much higher mutation rate leading to a risk of mutational collapse in the new lines.
