Aquaculture Malu
'Aina
makes
use
of
the
175-200
inches
of
annual
rainfall
in
east
Hawaii
for
homestead
aquaculture.
We
raise
Chinese
catfish
and
golden
and
green
tilapia
in
12
foot
diameter
3
feet
deep
tanks.
Water

are
constructed
using

2"X4"
galvanized
wire.
A
layer
of
heavy
roofing
paper
is
inserted
between
the
wire
and
fish
tank
food
grade
liner
as
a
cushion
for

used
to
remove
some
fish
waste,
the
tilapia
feed
on
the
hyacinth
roots
and
the
excess
hyacinths
are
used
as

.
Pest
fruit
flies
are
attracted
by
traps
on
the
tanks
for
supplemental
fish
food.
The
fish
waste
water
is
used
to
fertilize
various
field
crops
so
aquaculture
and
organic
farming
are
a
good
mix.
Creating
worm
boxes
near
the
tanks
for
fish
food
is
also
helpful
build
the
tanks
with
a
2
inch
drain
pipe
to
handle
heavy
rains
and
prevent
tank
overflow
and
loss
of
fish.
Water
level
should
be
kept
6
inches
below
the
tank
top.
It
is
recommended
to
place
several
pieces
of
3
or
4inch
PVC
pipe
lengths
of
3-4
feet
in
each
tank
for
catfish.
The
pipe
with
a
string
attached
to
each
end
can
also
serve
as
a
way
to
catch
the
catfish
when
a
net
is
placed
at
one
end
and
the
pipe
lifted.
