Insights from Journal of Aquaculture: Understanding Temperature Effects on Atlantic Salmon in Commercial Farms A recent publication in the Journal of Aquaculture titled "Influence of temperature on the behaviour and physiology of Atlantic salmon (Salmo Salar) on a commercial farm" sheds light on the critical role of temperature in shaping the physiology and behaviour of Atlantic salmon in commercial aquaculture settings. Authored by Jennie Korus, Ramón Filgueira, and Jon Grant, the study offers valuable insights into how rising sea temperatures and weather variability impact salmon health and production efficiency. As ectotherms, Atlantic salmon rely on environmental temperature to regulate metabolic rates, oxygen consumption, heart rate, activity levels, appetite, and growth. The manuscript explores the effects of thermal stress events on salmon physiology and behaviour, crucial for effective farm management under changing climatic conditions. Using biologgers measuring external acceleration, depth, heart rate, and temperature, the study monitored Atlantic salmon over 245 days to estimate the optimal temperature for growth and identify thermal stress limits. Results indicated an optimal temperature of 12.7°C, with apparent heart rate scope reduction observed below 2°C and above 19°C, indicating proximity to thermal stress thresholds. These findings bridge the gap between laboratory studies and real-world commercial operations, providing essential insights for aquaculture management. Understanding optimal temperature and thermal stress limits informs site selection, production cycle optimization, and regulatory decision-making in salmon aquaculture. The study's implications extend to informing government regulators about suitable farming locations and guiding husbandry decisions under challenging thermal conditions. By offering a baseline understanding of commercial fish responses to temperature challenges, the research paves the way for future studies on long-term monitoring and application of biologgers in aquaculture settings. This work was conducted in Nova Scotia, Canada and underscores the importance of continuous research and innovation in aquaculture to address climate-related challenges and optimize production practices. By leveraging biologgers and integrating scientific insights into farm management, the aquaculture industry can adapt to changing environmental conditions and enhance sustainability.

🐟 Exciting News in Aquaculture Research! 🌊 A new study published in "Aquaculture Reports" sheds light on enhancing the hypoxia tolerance of triploid rainbow trout. Researchers evaluated the impact of high protein-low carbohydrate (HPLC) and low protein-high carbohydrate (LPHC) diets on hypoxic tolerance. After an 80-day feeding trial, fish were subjected to acute hypoxic challenge. Results revealed that the HPLC diet significantly improved fish hypoxic tolerance compared to the LPHC diet. Fish fed the HPLC diet exhibited lower plasma levels of key enzymes associated with hypoxic stress and enhanced expression of genes related to anti-stress, antioxidant, and immune responses. Furthermore, the HPLC diet induced metabolic remodeling, regulating glucose, lipid, and protein metabolism genes. This study underscores the importance of diet composition in mitigating hypoxic stress and improving fish welfare.
