With appropriate treatment, any
water can be made suitable for use
in a catfish hatchery. Cost of treatment
is often not economically justifiable.
It is usually good practice
to use a source that provides, as
nearly as possible, water of correct
quality for optimum matchability
of eggs and survival and growth
of fry. Good water quality is maintained
in the hatchery by providing adequate water flow and aeration
to hatching and rearing
troughs. Frequent removal of uneaten
feed and other accumulated
organic debris will also aid in
maintaining proper rearing conditions
within troughs or tanks.
