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.

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.

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.
