Why is the temperature discontinuous in the growth range of cold water fish? 


Best insight from top research papers

The temperature discontinuity in the growth range of cold-water fish can be attributed to the physiological limits and thermal preferences of these species. Cold-water fish populations are vulnerable to global warming due to their requirement for habitats with low temperatures . While small temperature increases can benefit the growth of cold-blooded animals, including fish, warming can eventually exceed their physiological limits, resulting in reduced growth . Different species of cold-water fish have discrete thermal windows and life histories, which influence their response to temperature changes . For example, in Lake Stechlin, the densities of two coexisting Coregonus species were correlated with metalimnetic June temperatures, but in opposite directions due to their discrete thermal windows . Additionally, temperature can interact with other factors such as individual size and social environment to affect the growth and behavior of cold-water fish . These findings highlight the importance of considering the interaction of temperature with other factors when evaluating the phenotypes, ecology, and evolution of cold-water fish .

Why aquatic animals are more comfortable in cold water than in warm water ?3 answersAquatic animals are more comfortable in cold water than in warm water due to several factors. Cold-water environments provide optimal conditions for the growth and survival of many aquatic species, as temperature plays a major role in their biological activity and metabolism. Cold water holds more dissolved oxygen, which is essential for the survival of aquatic life, while warm water holds less dissolved oxygen, making it less suitable for their respiration. Additionally, cold-water environments often have lower levels of toxic substances and germs, which can inhibit the health and well-being of aquatic organisms. Furthermore, many cold-water species have evolved to thrive in extreme and fluctuating environmental conditions, allowing them to adapt and survive in cold-water habitats. Overall, the preference for cold water is driven by the physiological and ecological adaptations of aquatic animals to these specific environmental conditions.
Why temperature level effected fish health?5 answersTemperature levels can affect fish health due to their impact on physiological responses and immune system function. Exposure to suboptimal temperatures can lead to negative effects on the immune system, impairing the fish's ability to defend against pathogens and compromising overall health. Changes in temperature can also influence the oxidative stress levels and antioxidant response in fish, potentially leading to increased oxidative damage and susceptibility to inflammation and infections. Additionally, temperature fluctuations can affect the development and tolerance of fish at different life stages, with later stages generally being more tolerant of temperature changes. Temperature also plays a role in fish energy homeostasis, affecting metabolic rate, feeding behavior, digestion, and nutrient absorption. Overall, temperature levels have complex and species-specific effects on fish physiology, immunity, and energy balance, highlighting the importance of understanding and managing temperature impacts for both wild and aquaculture species.
How does temperature affect fish respiration?5 answersTemperature has a significant impact on fish respiration. Fish exposed to cold water experience a decrease in metabolic rates due to the effects of temperature on biochemical reactions. The respiratory metabolism of fish, such as the snakehead (Channa argus), is positively correlated with temperature, with resting metabolic rate (RMR) increasing as temperature rises. The thermal metabolic sensitivity of fish can vary depending on the temperature range, as indicated by the V-shaped Q10 values change in RMR. Acclimation to chronic temperature changes can reduce the metabolic thermal sensitivity of fish. Additionally, the regulation of ventilation frequency (VF) alone may not be sufficient to meet the oxygen demand of fish as temperature increases. Cold acclimation can lead to compensation in VF to maintain oxygen supply. Overall, temperature plays a crucial role in fish respiration, affecting metabolic rates and oxygen demand.
