While not specifically about predator presence, it shows how repeated acute stress affects growth and endocrine parameters in salmon.

Increasing dietary levels of the omega-3 long-chain polyunsaturated fatty acids, EPA and DHA, improves the growth, welfare, robustness, and fillet quality of Atlantic salmon in sea cages
While focusing on dietary EPA and DHA, this study mentions improved robustness and welfare in salmon, which could be relevant to stress responses, including those induced by predators.
Handling stress and water quality during live transportation and slaughter of Atlantic salmon (Salmo salar)
While not directly about predator presence, this study demonstrates how handling stress affects salmon meat quality, including pH levels, rigor mortis onset, and fillet gaping. It’s relevant because it shows how stress can directly impact product quality in farmed fish.
Stress during slaughter increases lipid metabolites and decreases oxidative stability of farmed rainbow trout (Oncorhynchus mykiss) during frozen storage
This research is important as it links pre-slaughter stress to decreased oxidative stability and shelf life of fish products. It’s relevant because it demonstrates how stress can have long-lasting effects on product quality, which could potentially be applied to predator-induced stress scenarios.
Handling Stress and Storage Temperature Affect Meat Quality of Farmed-raised Atlantic Salmon (Salmo Salar)
This study demonstrates how handling stress affects meat quality in farmed Atlantic salmon, which is relevant to understanding how predator-induced stress might impact product quality.
Farmed fish welfare: stress, post-mortem muscle metabolism, and stress-related meat quality changes
This review directly addresses the relationship between ante-mortem stress in farmed fish and its effects on post-mortem muscle metabolism and meat quality. It’s highly relevant as it discusses how stress responses in fish can significantly impact meat quality parameters such as texture, color, water-holding capacity, and shelf life.
Recent understanding of stress response on muscle quality of fish: From the perspective of industrial chain
This comprehensive review examines how stress affects fish muscle quality throughout the industrial chain, from aquaculture to processing and storage. It highlights how stress can lead to increased lipid oxidation, protein denaturation, and water loss in fish muscle, affecting texture, color, and flavor.
Hypoxia does not change responses to dietary omega-3 long-chain polyunsaturated fatty acids, but rather reduces dietary energy demand by Atlantic salmon
Examines the effects of hypoxia on salmon responses to dietary omega-3 fatty acids. Demonstrates how environmental stressors can affect fish physiology, which could be similar to predator-induced stress.
Regulation of the Omega-3 Fatty Acid Biosynthetic Pathway in Atlantic Salmon Hepatocytes
Studies the regulation of omega-3 fatty acid biosynthesis in salmon hepatocytes. Provides background on fish metabolism, which could be affected by predator-induced stress.
Atlantic Salmon Skin and Fillet Color Changes Effected by Perimortem Handling Stress, Rigor Mortis, and Ice Storage
This paper provides valuable insights into how stress affects the color and quality of Atlantic salmon.
