Summary: This review investigates the reasons behind fish heat failure at thermal extremes and the physiological mechanisms that determine acute upper thermal tolerance. The study proposes that rapid direct thermal impacts on fish are influenced by molecular mechanisms such as reaction rates, protein structure, and membrane fluidity. These molecular effects during acute warming lead to loss of equilibrium and death through different cellular, organ, and physiological pathways, including mitochondrial dysfunction, oxygen limitation, and impacted excitability of excitable cells. The study concludes that a single mechanism for acute upper thermal tolerance is not found across species and contexts, suggesting that the limiting mechanisms during acute warming differ between species, life stages, and recent thermal history. Future research is proposed to elucidate major patterns of physiological thermal limitations in fish.

Summary: In recent years, the large-scale cultivation and commercialization of microalgae/cyanobacteria biomasses have become a worldwide trend, mainly directed to the animal and human nutrition markets due to their outstanding nutritional value. Crocosphaera chwakensis CCY0110 is a marine unicellular cyanobacterium that produces a promising and versatile extracellular carbohydrate polymer (Cyanoflan). Therefore, envisaging a biorefinery approach with a multi-product stream (zero-waste), C. chwakensis biomass was cultivated at pilot-scale and its nutritional composition was evaluated.

Summary: Fish are influenced by their surrounding environment, including water temperature. In this study, the effects of water temperature ranging from 26 to 32 degrees Celsius on the growth performance and gastric emptying time of African catfish fingerlings were investigated. The experiment provided baseline data on the impact of water temperature on the culture of catfish, showing that temperatures between 26 to 32 degrees Celsius were suitable for the growth of African catfish fingerlings with gastric emptying times ranging between 10 and 16 hours. Further research on the physiological parameters of fish in different water temperatures is recommended for a better understanding of aquaculture practices.

Summary: This study investigated the effects of dietary selenium and oxidized fish oil on growth, nutritional composition, muscle development, antioxidant responses, and selenoprotein expression in yellow catfish. The results showed that oxidized fish oil had negative effects on growth and muscle development, but high dietary selenium levels alleviated these effects. Additionally, oxidized fish oil reduced the antioxidant capacity of fish muscle, while dietary selenium mitigated this effect. These findings are important for feed formulation and fish farming.

Summary: The fish processing industry generates solid biological waste that has serious environmental impacts. Fish waste can be valorized as fish protein hydrolysate (FPH) for cultivating Spirulina, leading to improved growth, biomass productivity, protein content, and pigment quality. Using fish waste as an organic nitrogen source is a potential sustainable and environmentally friendly solution for both fish waste valorization and Spirulina cultivation.

Summary: To determine the best strategy to produce phycocyanin in a cost-efficient way, the impact of light source and temperature on the growth of Spirulina subsalsa was examined. The results revealed that the highest growth rate was achieved at 35 degrees C, while the highest phycocyanin content was obtained under green light. Furthermore, a two-stage cultivation strategy combining biomass accumulation at 35 degrees C and phycocyanin synthesis under green light was proposed and implemented, resulting in significant phycocyanin production.

Summary: Changes in water temperature, particularly during winter months, due to wastewater treatment plants (WWTP) in the North American Great Plains can negatively affect reproductive cues and success of aquatic ectotherms, such as the johnny darter. Our study evaluated the effects of temperature and duration on reproductive success in the laboratory to inform water quality criteria for the South Platte River Basin.

Summary: Experiments in a novel pool & weir fishway showed that altering hydraulic conditions affected fish stress levels and physiological parameters. Increasing fishway slope and decreasing weir spacing led to changes in blood cell counts and stress indicators. Optimal conditions for fish included reduced cortisol levels with a weir spacing ratio of 6 and a fishway slope of 4%.

Summary: The rise in water temperature in the Amazon River has raised concerns about the impact on commercially important fish species like matrinxa. Research has shown that diets supplemented with nerolidol can prevent oxidative damage and maintain fatty acid profiles in fish exposed to heat stress. This study highlights the potential of nerolidol-supplemented diets as a strategy to mitigate heat stress-induced damage and maintain fish health.

Summary: An eight-week feeding trial was conducted to investigate the effects of oxidized fish oil and spoiled fish meal supplemented with different levels of vitamins E and C on rainbow trout. The study found that feeding fish with high levels of oxidized fish oil and vitamins resulted in decreased growth indices and increased hematological parameters and immune response. Additionally, vitamin supplementation effectively reduced intestinal tissue damage caused by the feed.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
