Glyphosate is a broad-spectrum, non-selective, systemic post-emergence herbicide/weedicide widely used to eradicate nuisance emergent and floating aquatic weeds (such as Eichhornia, Typha, and reeds) along pond margins and drainage canals.

Calcium Ammonium Nitrate (CAN), also called 'Kisan Khad', is a physiologically neutral fertilizer containing both ammoniacal and nitrate nitrogen alongside calcium carbonate. Unlike Ammonium sulphate and Urea (which exert acid-forming residual effects), CAN supplies calcium and neutralizes soil acidity, making it ideal for slightly acidic fish pond soils.

Mahua oil cake (Madhuca latifolia / Madhuca longifolia) contains 4% to 6% of the toxic triterpenoid saponin known as 'mowrin'. Applied at 2000–2500 kg/ha in nursery/rearing pond preparation, it acts as an effective botanical piscicide to eradicate predatory and weed fishes, degrading within 10–14 days to serve as rich organic manure.
