Profitability Dependence on Use of Disinfectants in Aquafarming
Aquafarming (fish, shrimp, prawn, and mollusk cultivation) is highly sensitive to water quality, pathogen loads, and disease outbreaks. The use of disinfectants—such as chlorine compounds, ozone, hydrogen peroxide, potassium permanganate, and iodophors—plays a crucial role in maintaining biosecurity and ensuring healthy stock growth. Profitability is directly influenced by how effectively and economically these disinfectants are applied.

1. Disease Prevention and Mortality Reduction
Without disinfectants: Fish/shrimp are exposed to high pathogen loads (bacteria, viruses, fungi, parasites). Disease outbreaks can cause 30–80% stock mortality, leading to severe financial losses.
With proper disinfectant use: Biofilm, pathogens, and parasites are controlled, mortality is reduced to 5–10%, ensuring higher survival rates and greater harvest volumes.
Profit impact: Higher survival rates mean more biomass per production cycle, improving yield and revenue.
2. Feed Conversion Efficiency (FCR)
Poor water quality: Increases stress and lowers feed utilization efficiency (FCR can increase from 1.4 to 2.0).
With disinfectants: Cleaner water reduces pathogen stress, allowing animals to convert feed more efficiently (FCR 1.2–1.4).
Profit impact: Lower feed cost per kilogram of fish/shrimp produced, saving 10–20% of operating costs
3. Marketability and Product Quality
Fish/shrimp raised in pathogen-free environments show:
Better growth rates.
Lower incidence of deformities or lesions.
Longer shelf-life post-harvest.
Profit impact: Higher market price (premium product, fewer rejections).
4. Operational Continuity
Without disinfection: Disease outbreaks force farmers to halt or abandon cycles, disinfect ponds, and restart production.
With disinfection programs: Farms can run continuous cycles, reducing downtime.
Profit impact: More production cycles per year, increasing annual revenue.
5. Cost–Benefit Balance
Disinfectant cost share: Typically 3–7% of operational expenses in aquafarming.
Potential savings/benefits:
Avoiding massive stock losses.
Reducing antibiotic usage (lower regulatory risks and costs).
Ensuring predictable yields.
