Influences of thermal stress on the growth biometrics, stress indicators, oxidative stress biomarkers, and histopathological alterations in European seabass, Dicentrarchus labrax, juveniles.

Summary: Imagine you are raising young seabass. What is the perfect water temperature for them to grow big and strong? Scientists tested these fish in water ranging from 20°C (68°F) up to 31°C (88°F). They found that the fish did best in warm water around 23°C to 26°C. But when the water got too hot (31°C), the fish got very sick. They stopped growing, their stress levels went way up, and their organs like the liver, kidneys, and gills were badly damaged. This is a big warning for fish farmers, as global warming continues to make ocean waters hotter.
