🐟Pangassius (Striped Catfish) Culture — 1 Ha

NABARD model bankable project for Pangassius hypophthalamus monoculture in 1 hectare pond. Covers air-breathing fish biology, 20 tonnes/crop potential, capital cost of ₹8.97 lakh, and financial indicators for IBPS AFO and NABARD Grade A exams.

Pangassius hypophthalamus (Striped catfish / Swai / Siamese shark) is an exotic freshwater catfish from the Mekong basin, first introduced to India in 1997 from Thailand via West Bengal. By 2008 it was farmed across ~40,000 ha in India with production of 1.80–2.20 lakh tonnes.

  • An air-breathing fish — tolerates very low dissolved oxygen levels (DO as low as 0.1 mg/l)
  • Can be cultured in ponds, concrete tanks, cages, pens, and abandoned shrimp farms
  • No intramuscular bones — flesh is easily filleted, excellent for domestic and export processing

Pangassius (Basa fish) culture — high-density freshwater farming
Pangassius hypophthalmus (Basa): 1 kg in 6–8 months, FCR 1.5–2.0. Tolerates low DO via accessory breathing organ.

Key Advantages for Culture

FeatureDetail
Growth rateAttains 1.0–1.5 kg in 8–10 months
Air-breathingTolerates low DO; does not require aeration
High stocking densityUp to 20,000/ha (monoculture semi-intensive)
Omnivore → herbivoreFirst year omnivorous, subsequent years herbivorous
FCR2.35 : 1 (use floating pellets for better FCR)
Saline toleranceCan grow in low-salinity brackish water (abandoned shrimp ponds)

NOTE

Exam trap: Pangassius is an air-breathing fish (family Pangassidae). It can survive in oxygen-depleted water that would kill carps. This is frequently tested alongside the DO tolerance of < 0.1 mg/l.

NOTE

Pangassius has the highest capital cost (₹8.97 lakh) among NABARD freshwater pond fish models due to intensive pond construction (800 machine-hours). Its high feed cost (₹9 lakh/crop) reflects the FCR of 2.35:1 — higher than carps or tilapia.
