An unusually high upper thermal acclimation potential for rainbow trout

Olivia A. Adams et al.

Summary: The study explores the thermal acclimation potential of rainbow trout and finds that the Australian H-strain of rainbow trout has a remarkably high thermal acclimation potential. Growth and aerobic capacity decline significantly at high temperatures, along with an increase in the time and cost of digestion. The findings highlight the importance of considering intra-specific genetic variation in fish species when predicting the impact of global warming.

Dietary inclusion of a marine microalgae meal for Atlantic salmon (Salmo salar): Impact of Pavlova sp. 459 on growth performance and tissue lipid composition

Minmin Wei et al.

Summary: The study investigated the use of an intact-cell meal produced from the marine microalga Pavlova sp. CCMP459 as a protein and lipid source in the diets for post-smolt Atlantic salmon. The results showed that the inclusion of Pav459 meal in the salmon diets did not significantly affect the growth performance and tissue fatty acid profiles of the fish. Salmon fed diets containing Pav459 meal had a slightly higher condition factor compared to those fed the control diet.

Acute critical thermal maximum does not predict chronic incremental thermal maximum in Atlantic salmon (Salmo salar)

Charlotte B. Bartlett et al.

Summary: This study investigated the thermal tolerance of Atlantic salmon and found that critical thermal maximum (CTmax) cannot predict incremental thermal maximum (ITmax). Additionally, the relationship between body size, cardiac metrics, blood metrics and thermal tolerance was examined. The results highlight the need to be cautious when using acute thermal tolerance tests to predict real-world responses to rising temperatures.

Global gene expression responses of Atlantic salmon skin to Moritella viscosa

Khalil Eslamloo et al.

Summary: This study characterized the transcriptome responses of Atlantic salmon skin infected with the pathogen Moritella viscosa. The results revealed massive and strong dysregulations in the transcriptome at the infection site, while effects beyond the lesion site were comparably subtle. The transcripts induced by M. viscosa were mainly involved in immune response-related pathways.

Diet and temperature affect liver lipids and membrane properties in steelhead trout (Oncorhynchus mykiss)

Manjusri P. A. Wijekoon et al.

Summary: This study evaluated the effects of diet and temperature on liver membranes in steelhead trout, finding that fish fed H-n3 diet showed the best adaptability to temperature changes, while those fed L-n3 diet had increased membrane fluidity. Changes in sterol:phospholipid ratios were identified as key responses for membrane adaptability to environmental changes.

Summary: The study found that European seabass fed on diets supplemented with vitamins C, vitamin E, propolis, and phycocyanin showed improved growth performance and survival rate in extreme environments. Blood parameters, heat shock proteins, and antioxidant enzyme activities differed significantly among fish fed on different dietary supplements under heat stress conditions.

The transcriptomic responses of Atlantic salmon (Salmo salar) to high temperature stress alone, and in combination with moderate hypoxia

Anne Beemelmanns et al.

Summary: Increasing temperature to 20 degrees C alone, and in combination with hypoxia, resulted in differential expression of genes involved in similar pathways in Atlantic salmon. However, heat shock and immune-related genes in fish exposed to 20 degrees C and hypoxia were more affected, and strongly related to phenotypic characteristics such as growth. This study provides valuable information on how environmental challenges affect the expression of stress-, metabolic- and immune-related genes in fish, identifying potential biomarker genes for fish health and welfare improvement.

Thu Thi Minh Vo et al.

Summary: The reduction in flesh pigmentation of farmed Atlantic salmon was investigated using RNA sequencing. Differential gene expression analysis between different flesh color phenotypes revealed associations with metal ion transport, oxidation-reduction processes, immune responses, and lipid metabolism. The study compared two library preparation methods and found similarities in the trend of differentially expressed genes validated by qPCR.

Phenotypic stress response does not influence the upper thermal tolerance of male Atlantic salmon (Salmo salar)

Eric H. Ignatz et al.

Summary: The study concluded that the stress response characteristics of Atlantic salmon at low temperatures do not accurately predict their survival and stress response at high temperatures. Interestingly, the salmon showed increased feed intake at temperatures up to 22 degrees C, contrary to previous findings. The results also suggest that the thermal tolerance of this population of salmon is high, questioning the relevance of CTMax in real-world temperature changes.

Atlantic Salmon (Salmo salar) Cage-Site Distribution, Behavior, and Physiology During a Newfoundland Heat Wave

Anthony K. Gamperl et al.

Summary: The study investigates the impact of climate change on the Atlantic salmon aquaculture industry, highlighting the challenges posed by increased water temperatures and reduced oxygen levels. By utilizing data storage tags, researchers were able to monitor the effects of sea-cage conditions on the physiology and behavior of salmon. The results suggest that pathogen challenges combined with high temperatures, rather than just high temperatures and moderate hypoxia, present the biggest climate-related challenge for the industry.

The Atlantic salmon's stress- and immune-related transcriptional responses to moderate hypoxia, an incremental temperature increase, and these challenges combined

Anne Beemelmanns et al.

Summary: The study found that moderate hypoxia had an impact on the expression of stress genes at 12 degrees Celsius, while the effect of high temperature on these genes increased with rising temperatures. Long-term exposure to 20 degrees Celsius, with or without hypoxia, resulted in a limited acclimatory response in salmon. Additionally, immune-related genes were significantly affected at 20 degrees Celsius, especially when exposed to hypoxia challenge.

Climate Change Effects on Aquaculture Production: Sustainability Implications, Mitigation, and Adaptations

Sahya Maulu et al.

Summary: The aquaculture sector is rapidly expanding globally, but its sustainability is threatened by the effects of climate change. The potential impacts of climate change on aquaculture production, such as rising temperatures and sea-level rise, have been discussed. While there are both negative and positive effects, successful adaptation will depend on the adaptive capacity of producers worldwide.

Sudden increased mortality in large seemingly healthy farmed Atlantic salmon (Salmo salar L.) was associated with environmental and dietary changes

J-E. Dessen et al.

Summary: Mortality of seemingly healthy farmed Atlantic salmon is a significant issue in Norwegian aquaculture, with this study reporting a sudden death event during winter in northern Norway. The experimental fish fed test diets showed increased mortality, higher liver lipid content, altered fatty acid composition, and elevated enzyme levels compared to non-dying fish. Immediate reduction in mortality was observed when the fish were starved, indicating a potential link between dietary and environmental changes and the observed mortality.
