RAS and Biofloc: Water-Saving Aquaculture Technologies Under PMMSY
Why in the news
A PIB feature explained how RAS and Biofloc are reshaping fish farming under PMMSY.
Key facts
| Feature | RAS | Biofloc |
|---|---|---|
| Core method | Mechanical and biological filtration plus recirculation | Beneficial microbes manage waste and water quality |
| Water | 90–95% recycled | Less exchange needed |
| Extra | Controlled environment | Biomass doubles as fish food |
India in global fisheries
- Second-largest fish producer, about 8% of the world total.
- Second in aquaculture and capture fisheries; largest shrimp producer and exporter.
- About three crore people depend on fishing and fish farming.
Exam angle
- Scheme linked: PMMSY.
- RAS equals filtration; Biofloc equals microbes.
