Fish Farming in Winter: Protect Your Catch from Cold, Boost Profits

• Fish are cold-blooded; their body temperature depends on water temperature, slowing activities in cold.
• Warm-water fish like rohu, catla, and mrigal are sensitive to cold, unlike cold-water species such as trout and salmon.
• Maintain sufficient pond depth and change 10-15% of water daily with warmer borewell water (around 25°C) in winter.
• Avoid sudden temperature changes; adding 25°C water to a 15°C pond can cause temperature shock, especially in smaller ponds.
• Tank culture offers better temperature control, maintaining ideal conditions (25-27°C) for fish growth even when natural water temperatures drop.

Why It Matters: Proper winter care, including temperature management and pond depth, is crucial for profitable fish farming.
