The following are the constraints of fish feed production using maggot
i)
Water logging of
substrate during rains hinders the production of maggot.
ii)
Harmattan or dry
air dries the substrate faster.
iii)
Direct sunlight
on substrate hinders the production of maggot.
iv)
Ants (soldier
ants) most times take over the substrates.
SOLUTION
i)
Cover the open
sided walls with bamboo mats or dark colored plastic sheets well arranged
for
ventilation.
ii)
Maintain water
regularly in the canal to prevent ants from having access to the substrate.
iii)
During harmattan,
water the substrates frequently. Turn substrates after every harvest.
iv)
Inspect and
repair cracks inside the building.
v)
Set traps to
prevent birds from having access to the substrates.
The
operator must be vigilance enough to harvest the maggots earlier before they
could pass to the next stage.
