In fish farming, stress parameters include environmental factors such as water temperature, oxygen concentration, ammonia levels, and stocking density, which can negatively impact fish health and productivity. High levels of noise, sudden handling, or overcrowding can also contribute to stress. Monitoring these parameters regularly helps identify stress before it leads to serious health issues. Stress responses in fish can include changes in behavior, reduced growth rates, and weakened immune systems. Effective management of stress factors is essential for maintaining the welfare of fish and optimizing the efficiency of aquaculture operations.
