Catfish Diets
Feed offers more opportunity for reducing production costs than any other single variable expense in catfish production. Although catfish rations are generally lower in protein than those of cold-water fish, protein still remains the most expensive nutrient group. Analysing the latest available nutritional data, we carefully scrutinized all possible areas for reducing feed costs without losing nutritional value. AQUANUTRO’s CATFISH GROWER is the result. We changed quantity and sources to produce an economically viable feed for the catfish industry. If fish are uniformly stocked, the grower diet will assist in rapid marketability of fish, decreasing the grow-out period. Due to the high densities at which catfish are reared, cannibalism is always a potential loss. When managed correctly, this grower diet will reduce that possibility to a minimum through minimised nutrient variability between feed pellets. It is uniform in composition and remains water stable for a much longer period, decreasing the leaching of expensive nutrients. Its floatability helps the
catfish producer to observe the condition of feeding fish, especially in murky water.

  • Crude Protein, not less than 450 g/kg
• Crude Fat, not less than 80 g/kg
• Crude Fibre, not more than 40 g/kg
• Calcium, not more than 30 g/kg
• Phosphorous, not less than 7 g/kg
 

Catfish pre-starter
Highly digestible hatchery crumbles that supports maximum growth rates of catfish fry during yolk sack absorption. Sieved to fit specific sizes of fry, allowing more feed to be consumed while maintaining water quality and reducing loss by dust fouling and leaching of expensive water-soluble nutrients.
 

  • Crude Protein, not less than 400 g/kg
• Crude Fat, not less than 80 g/kg
• Crude Fibre, not more than 40 g/kg
• Calcium, not more than 30 g/kg
• Phosphorous, not less than 7 g/kg
 

Catfish Starter
After weaning fry from the hatchery to a grow-out system, feed conversion efficiency determines the economic viability of catfish aquaculture – this continue with growing strong, healthy fingerlings on AQUANUTRO’s CATFISH STARTER diet.
