Abstract

---

Climate change is already exerting significant pressure on marine ecosystems, primarily due to rising sea temperatures and decreasing ocean ph. levels. Projections indicate that over the next 50 years, ocean temperatures could increase by 2°C, while ph. levels may drop by 0.2 units. These shifts pose serious challenges, particularly for aquaculture and food quality. In this study, we investigated the effects of climate change on the queen scallop, Aequipecten opercula is (Linnaeus, 1758), under simulated future environmental conditions. Additionally, we evaluated the impact of a nutrient-enriched diet supplemented with the probiotic culture Lactiplantibacillus plant arum I on scallops in both native and climate-altered environments. To assess these influences, we measured the scallops’ morphometric parameters before and after one month of controlled exposure. Furthermore, we analysed commercial quality traits and somatic indices across all experimental conditions. Our findings suggest that queen scallops show promising resilience to changing environmental factors, particularly when their diet is supplemented with the probiotic Lpb. Plantarum I. This adaptation could offer a viable strategy for maintaining aquaculture productivity and food quality in the face of on-going climate change.
