Abstract
The Cephalopod Gastrointestinal Simulation System (CGSS) was developed and validated as a novel in vitro model to study digestive physiology in Octopus maya. This system replicates physiological digestion using gastric juice from O. maya and offers an ethical, cost-effective alternative to traditional in vivo methods.
The CGSS demonstrated high concordance with in vivo trials, with no significant differences in protein digestion (p > 0.05). For instance, protein digestion values were 0.567 ± 0.012 mg/mL (in vitro) and 0.562 ± 0.035 mg/mL (in vivo), confirming the system’s reliability. The CGSS provides a practical tool for optimizing diet formulations, including the use of alternative, sustainable ingredients. By reducing reliance on live animals, the system aligns with ethical research practices and promotes sustainability in aquaculture. This innovative model supports advancements in cephalopod culture, offering reliable, scalable solutions for improving productivity and understanding digestive processes in O. maya and other species.
