FERTILIZING THE POND
There is no need to
fertilize ponds for catfish grow-out if the fish are fed on
nutritionally-complete pellets. This is because all their food requirements are
derived from the feed. Catfish grow-out monoculture pond fed nutritionally
complete pellets only need to be limed if:
a.
The pond soils are acidic, pH 5 and
below. In this case, lime with agricultural lime, preferably in the fine powder
form by spreading uniformly over the pond bottom or pond.
b.
The pond cannot drain completely. In
this case, lime the remaining puddles with builders lime (Ca (OH)2)
or quick lime (CaO) until the water pH increases to 11. The objective of attaining such a high pH in this case is to kill off
any fish frogs, potential diseases or parasites that might remain within the
pond. Spread the lime over the pond bottom while paying extra attention to
potential hiding places. This is necessary because any catfish left in a pond
from a previous cycle can easily literally predate on all the new stock. After
liming, the pond can be filled with water the following day but only stock it when the pH has
decreased.
