Thriving in the Cold: Essential Winter Crop Management Tips for Shrimp Culture

 

Winter season brings its own challenges in shrimp farming such as cold wave invasion and temperature differences making the water quality extremely unstable. This increases the pond pollution in shrimp ponds, making shrimp more susceptible to diseases. In the second episode of Skretting India’s Podcast series, Dr. G. Raghavendrudu, Product Manager Aqua Feed, explains all aspects of management and disease prevention measures in winter for the successful shrimp culture. Let’s go through some best practices for winter crop management in shrimp farming:

Water temperature management: Monitor and maintain optimal water temperatures for shrimp growth, which may vary depending on the specific species being cultivated. Use water heaters or insulation to prevent water temperature from dropping too low. Maintain a stable and suitable temperature range to promote shrimp activity and feed consumption.

Water quality monitoring: Regularly monitor water quality parameters such as dissolved oxygen levels, pH, salinity, and ammonia. Cold temperatures can affect water chemistry, so it's important to ensure appropriate levels to support shrimp health. Provide adequate aeration and circulation to maintain oxygen levels and prevent stratification.

Feeding adjustments: Shrimp metabolism may slow down during winter, leading to reduced appetite. Adjust feeding rates and frequencies accordingly to prevent overfeeding and water quality issues. Monitor shrimp feeding response and adjust feed formulation as needed.

Pond bottom management: During winter, organic matter decomposition may slow down, leading to the accumulation of sludge at the pond bottom. Regularly monitor and manage the pond bottom by occasional stirring to prevent anaerobic conditions and maintain good water quality.

Disease prevention: Lower water temperatures can increase the risk of certain diseases and infections in shrimp. Implement strict biosecurity measures to prevent the introduction and spread of pathogens. Regularly monitor shrimp health and promptly address any signs of disease with the guidance of a veterinarian.
