Pond Fish Suffer Most from Cold: Exercise Crucial to Prevent Losses

• Fish are cold-blooded, meaning their body temperature is directly affected by the surrounding water temperature.
• Pond fish are more susceptible to cold than river or sea fish due to stagnant water cooling faster.
• As temperatures drop below 25 degrees Celsius, fish become stressed, impacting their growth and health.
• Farmers use methods like adding warm borewell water or 'exercising' fish with nets to maintain warmth and activity.
• Regular monitoring, water changes, and ensuring movement are vital for fish health and preventing losses in winter.

Why It Matters: Pond fish are highly vulnerable to cold; proper temperature management and exercise are essential for their survival.
