Boost your fish farming productivity with expert advice from Dr. Meera D. Ansal, Dean of the College of Fisheries at GADVASU. Learn how to maintain optimal water quality, oxygen levels, and disease prevention strategies for sustainable income growth.
In the hot summer months spanning from March/April to October/November in northern India, fish farming presents a lucrative opportunity for farmers to increase their earnings. However, maximising productivity in fish farming requires smart management techniques tailored to address the unique challenges posed by the region’s climate.
Dr. Ansal emphasises the importance of implementing strategic strategies to maximise output and safeguard fish stocks during the scorching summer months. Key tips include maintaining suitable water temperatures by ensuring a water depth of 5-6 feet to create a comfortable environment for fish growth.
Monitoring oxygen levels in ponds is crucial, especially during dawn when biological activity peaks. Farmers are advised to aerate ponds before sunrise to maintain optimal oxygen levels and prevent fish from suffocating at the water surface.
Regular water quality maintenance is essential for promoting fish growth. Dr. Ansal recommends periodic water exchange to enhance nutrient levels and promote plankton production, a vital food source for fish. Nutrient-rich Pond water can also be used for irrigating agricultural fields, reducing the need for external fertilisers.
Feeding routines significantly impact production targets. Dr. Ansal advocates for the use of farm-made pellet feeds to minimise wastage and improve feed conversion efficiency. However, farmers must remain vigilant for signs of water discoloration or algal blooms, which may require temporary suspension of feeding activities.
Maintaining optimal pH levels is crucial for fish health. Dr. Ansal suggests monitoring pH levels regularly and applying lime or alum/gypsum as needed to maintain the ideal pH range.
Proactive disease prevention measures, such as disinfection and biosecurity protocols, are essential. Consultation with experts is recommended for accurate diagnosis and treatment in cases of disease outbreaks.
By implementing sensible management strategies and following professional advice, farmers in North India can ensure a sustainable source of income and increase the productivity of their fish farming operations. Prioritising water quality, oxygen management, feeding regimes, and disease prevention measures are key to achieving optimal results.
