Cyclone Arnab has reportedly created difficult conditions for aquaculture farmers in Andhra Pradesh’s Konaseema district, raising concerns over shrimp health, farm operations and the risk of financial losses.
Farmers are facing multiple challenges following the adverse weather, including power interruptions, damage to electrical equipment and difficulties in maintaining routine pond management. For farmers who have invested lakhs of rupees in a crop, prolonged disruptions can put their investment at risk.
Power Outages Disrupt Pond Management
Electricity is essential for operating aerators and other equipment that maintain dissolved oxygen levels in shrimp ponds. According to the concerns raised by farmers, power cuts during the adverse weather have affected motors and aerator systems, with some equipment reportedly damaged or burnt out.
When aeration is disrupted, dissolved oxygen can fall, particularly in heavily stocked ponds. Low oxygen levels can stress shrimp, reduce feeding activity and, in severe cases, cause mortality.
Equipment damage can also increase repair costs and leave farmers struggling to maintain normal pond operations during unstable weather conditions.
Shrimp Health and Water Quality Concerns
Farmers have also expressed concerns about possible Vibrio bacterial problems following the weather disturbance. Changes in pond conditions can increase stress on shrimp and create conditions that favour certain bacterial problems.
However, Vibrio-related disease cannot be confirmed from weather conditions or symptoms alone. Water-quality testing, shrimp health assessment and, where necessary, laboratory diagnosis are important to identify the actual cause.
Farmers should closely monitor dissolved oxygen, pH, temperature and other relevant water-quality parameters, while watching for changes in shrimp behaviour and feed consumption.
Feeding Becomes Difficult During Bad Weather
Adverse weather can disrupt regular feeding schedules. When shrimp show reduced feed consumption, continuing to feed at the usual quantity may increase uneaten feed and organic waste in the pond.
Farmers should assess feed-tray responses and shrimp behaviour before adjusting feed quantities. Maintaining water quality and restoring essential equipment should remain priorities when pond conditions become unstable.
Farmers Seek Government Support
The reported difficulties have renewed concerns about the financial vulnerability of aquaculture farmers during extreme weather events. Damage to equipment, interrupted farm operations and potential crop losses can add to the burden of an already costly production cycle.
Farmers facing these challenges need timely technical assistance and assessment of eligible losses. Calls have also been made for government support to help affected aquaculture farmers recover.
The extent of damage and the number of farms affected require further verification.
For farmers in cyclone-affected areas, prompt attention to aeration, water quality and shrimp health is critical to reducing further risks to their crops.
