Fingerling seed sourcing and disease-free certification

Fingerling seed is the juvenile life stage of cultured fish and shrimp at which they are stocked into grow-out ponds. Sourcing fingerlings from registered, disease-free hatcheries is treated as a primary control point in Indian aquaculture, with the Department of Fisheries (Government of India) and ICAR institutes maintaining accreditation and seed-certification standards.

Principle

Survival and productivity in pond culture depend heavily on the genetic quality and health status of the stocked seed. Disease introduced through infected seed (notably white spot disease in shrimp, EHP and bacterial septicaemia in murrel and carp) can wipe out entire crops despite correct pond management. Sourcing from accredited hatcheries minimises this risk.

Implementation

The Department of Fisheries' hatchery accreditation framework involves assessment of at least three production batches at the spawn, fry and fingerling stages, with PCR and ELISA screening for notifiable pathogens. ICAR-CIBA (Central Institute of Brackishwater Aquaculture, Chennai, established 1987) is the nodal agency for brackishwater seed (including vannamei, see Vannamei Shrimp Farming), while ICAR-CIFA Bhubaneswar handles freshwater seed for carps (Carp Polyculture Pond) and murrel (Murrel Korameenu Farming). Domesticated, pellet-trained lines such as the Vietnamese strain of striped snakehead (Vietnamese Strain Korameenu) are sourced from feed-trained hatcheries rather than wild capture.

Adoption context

Mission Fingerling was launched under the Blue Revolution programme specifically to ensure supply of healthy, disease-free, fast-growing seed for inland and coastal aquaculture, with infrastructure support continued under PMMSY (Pmmsy). Seed certification has progressively shifted Indian shrimp and murrel farming away from wild-caught and uncertified seed.

Limitations

Poor-quality seed is recognised as a primary cause of crop failure in shrimp and murrel farming. Counterfeit certification, unregistered seed traders, and informal stocking remain challenges in the field; PCR screening at the farm gate is the recommended additional safeguard.
