Physiological Responses of Scallops and Mussels to Environmental Variability : Implications for Future Shellfish Aquaculture
Highlights• This study provides suggestions to the aquaculture industry to obtain different marketable attributes in shellfish like size, shell strength, lipid, and fatty acid content.• Cultured mussels and scallops can be placed at shallow depths to optimize growth.• Higher growth was associated with stronger shell integrity in mussels but not scallops, suggesting that scallops may be better adapted to acidic conditions.• Healthy and tasty polyunsaturated fatty acids can be optimized by placing mussels at deep depths in the spring for mussels, and winter for scallops.• Mussels and scallops had higher (more negative) δ 13 C levels in winter at 5 m indicating a more terrestrial based diet, and higher δ 15 N at 30 min in both winter and spring indicating sub-lethal stress or excess nutrient levels.• Our study highlights the importance of conducting field-based experiments to highlight spatiotemporal differences in physiology and provide the science community, aquaculture stakeholders, and policy makers with more robust and environmentally relevant results
