§1What this business is
Fish and shrimp farmers lose whole crops to disease and bad water. The lab tests water for pH, oxygen, ammonia and similar measures, checks seed and feed quality, examines sick fish and advises treatment, for a fee per sample or per visit. PMMSY lists two beneficiary schemes: a disease diagnostic and quality testing lab at a unit cost of ₹25 lakh, and a mobile lab or clinic at ₹35 lakh.
§2Is it right for you?
Who it is for
A fisheries graduate or aquaculture consultant based in a district with many ponds or shrimp farms.
Who it is not for
Someone without technical training in fish health.
Advantages
- Aquaculture clusters have very few testing labs
- Farmers pay for advice that saves a crop
- A mobile lab can cover many villages
Drawbacks
- Needs a qualified fisheries or microbiology professional
- Test kits and reagents are a running cost
- Work is seasonal with the culture cycle
Skills you need
- Water and soil analysis
