Stocking density effects on growth and production of the threatened silurid catfish, Mystus cavasius (Hamilton) fingerlings in nursery ponds

The fingerling-rearing experiment of the threatened catfish, Mystus cavasius was carried out at different stocking densities in earthen nursery ponds. Twelve-day-old fry were stocked at 200 000 ha−1 in treatment-1 (T1), 250 000 ha−1 in treatment-2 (T2) and 300 000 ha−1 in treatment-3 (T3) respective...
