SPAWNING IN TANKS
Fish
spawning can also be carried out in outdoor or indoor concrete or plastic
tanks. Breeding tanks can be in the form of small aquaria (glass or plastic) or
large fiberglass and concrete tanks. Broodstocks may be induce or just allowed
to freely spawn by mutual stimulation resulting from proximity of the male and
female parents. Outdoor spawning tanks are always covered with net mesh for
protection against predation by insects, birds and reptiles.
Most
commercial fish farms, which may not have a complete hatchery complex, always,
have one to four concrete tanks dedicated for breeding/spawning, where fry can
be harvested to earthen nursery ponds and ten percent of hatchling can
harvested as fry.
