Learn the facts
about live bait tanks wells systems Using live bait is an
expensive investment for most anglers. Why purchase or catch live bait, only to have them
perish before the fishing trip's
end.
There
are many misconceptions about aeration
systems.
Two
common fallacies are:
Large
live wells are required to sustain a
large quantity of fish.
Large
live well pumps are needed to move
large quantities of water through
the live well to keep live bait and
fish alive.
To
understand what is really needed for
proper aeration, it is best to take a
parallel look at ourselves and fish.
HUMANS
ILLUSTRATION
If
we were enclosed in a large airtight
room we would be able to breathe for
many hours before we would consume
all the oxygen.
If
we were in an airtight closet, the
oxygen would be consumed a lot
quicker.
If
we were swimming underwater without
a snorkel, the oxygen in our lungs
would be consumed very quickly.
In
all cases, without additional oxygen
we would eventually expire!
However,
we could stay alive indefinitely, if we
could use a breathing tube or snorkel
that was in contact with outside fresh
air or oxygen. It would not matter about
the size of the container or the quality
or air that surrounded us.
FISH
ILLUSTRATION
If
we enclosed a fish in a sealed,
1,000 gallon tank, it would survive
for a long time before consuming all
the oxygen.
If
we enclosed the same fish in a
sealed 10 gallon tank, the oxygen
would be consumed more quickly.
If
we removed the same fish from the
tank and placed it on a table, the
fish could live for an extremely
short time.
In
all cases, without additional oxygen
the fish would eventually die.
However,
our fish could stay alive indefinitely
if we could put oxygenated water through
its gills and keep it wet. It
would not matter about the size of the
tank.
AN
AERATOR IS TO A FISH, WHAT A SNORKEL IS
TO US!
SIZE
OF AERATORS AND SNORKELS
FACTS
It
is more difficult to breathe through
a straw than through a large
snorkel.
A
small or ineffective aerator cannot
provide as much oxygen in the water
as a larger or more effective one.
If
an aerator can provide enough oxygen
in the water for the fish to
breathe, it doesn't matter how much
water surrounds the fish! The only
reason that water must be changed
occasionally in live wells is to
remove ammonia. The smaller the
container of water, the more
frequent the changing.
BASIC
REQUIREMENTS OF AERATION
There
are two major considerations in
aeration.
1. The
gentleness and direction of water flow
2. The size and amount of the air
bubbles
3. The temperature of the water
GENTLENESS
AND DIRECTION OF WATER FLOW
FISH
THAT SWIM IN SCHOOLS
Delicate bait
such as shad, green-backs and croakers
will not survive a day of fishing unless
the water flow in the well is soft and
gentle. Turbulent water will damage the
bait and force them to work against the
current. Ideal water flow within the
well should be approximately 1 to 2 MPH,
and in a circular motion. This will
allow fish to school and provide a
smooth flow of water over and through
their gills. If the water flow is
excessive, bait tire quickly and will
not be lively. Keep water flow as low as
possible, with fish swimming in a
stationary position within the tank.
SHRIMP
AND FISH THAT DO NOT SCHOOL
Species that do not school do not need a
circular or oval container. Keep water
flow to a minimum for fish such as bass,
redfish, crappie, bream, and walleye.
For
shrimp, provide material in the well so
they can cling and not be swirling about
the well and become damaged. Leave a dip
net in the well, or tie a stone in a
piece of cloth such as burlap
SIZE
AND AMOUNT OF AIR BUBBLES
Take
a look at at the air bubbles produced by
an aquarium aerator. Watch how quickly
the bubbles rise to the surface. They
provide little aeration, but are
aesthetically pleasing to watch. Bubbles
must remain contacting the water, if
they are to do the job properly. A good
rule of thumb is: The smaller the
bubble, the longer it will remain
suspended in water to dissolve.
WATER
TEMPERATURES
The
warmer the water, the less oxygen it
will hold. Fish will deplete the oxygen
quicker as the water warms, and poor
aerators will maintain less fish.
Colder water will hold more
oxygen. Water frozen in a plastic bottle
will lower temperatures and keep the
chlorine out of the tank.
Use
an aquarium thermometer to compare
temperatures. Keep temperatures within
eight degrees Fahrenheit between water in
the well, and water outside the boat.
CAUTION:
Placing
fish in different temperatures quickly
will shock and kill them. It is best to
place fish in the same water and
temperatures where they were caught.
LIVEWELLS
Livewells
come in many shapes and sizes. Oval or
round tanks provide the best
circulation. However, rectangular or
square wells are satisfactory if there
is a directional discharge into the
well. The directional discharge will
induce the more desirable circular
motion.
Species
that do not school, do not need a
circular or oval container. Keep water
flow to a minimum for fish such as bass,
redfish, crappie, bream and walleye.
They do not need a water flow for
survival.
For
shrimp, provide material in the well so
they can cling and not be swirling about
the well and become damaged. Leave a dip
net in the well or tie a stone in a
piece of cloth such as burlap.
AIR
VERSUS OXYGEN
Oxygen
will maintain higher quantities of
fish, but extra care must be taken when
using pure oxygen. To understand the
fundamentals or air versus oxygen, each
should be individually discussed.
AIR
A
human breathes in oxygen and gives off
carbon dioxide (CO2). The CO2 is then
dissipated into the atmosphere.
A
fish breathes in oxygen from the water
and gives off CO2. The CO2 is absorbed
into the surrounding water. The CO2 is
then dissipated into the atmosphere
through the process of aeration.
An
air bubble as it passes through water
has the ability to put oxygen into the
water and also absorb CO2 as it passes
slowly to the surface. The bubble then
pops at the surface and the CO2 is
dissipated into the atmosphere. The
smaller the bubble, the longer it
remains in the water to exchange oxygen
and CO2.
OXYGEN
An
oxygen bubble will insert a higher
percentage of oxygen into water than a
normal air bubble. This allows for
higher quantities of fish in a given
size of container, or it will make bait
fish lively. However, an oxygen bubble
does not have the ability to absorb CO2.
As the fish eliminates CO2 in
it’s body, there will be a build-up of
CO2 in the livewell water. When the
percentage of CO2 equals that of the
fish, the fish will be unable to expel
the CO2 and absorb the enriched
oxygenated water. If a closed livewell
does not have the ability to aerate and
remove the CO2, the fish will suffocate.
CAUTION:
TOO MUCH OXYGEN WILL KILL YOUR FISH!
SPRAY
BAR AERATORS
Spray
bar aerators add oxygen to the water by
jetting small streams of water into the
surface. Some air is absorbed into the
spray as it passes from the spray bar to
the water surface, and when the spray
strikes the water surface, air bubbles
are injected into the water. For the
most part, these bubbles are rather
large.
Jets
of water from spray bars are generally
harsh to delicate bait. Their protective
coating and scales are easily removed,
and their survival is drastically
reduced.
Spray
bars are an inefficient aeration system,
and should be used only on the hardiest
bait.
AIR
STONE AERATORS
Air
stone aerators are an inexpensive way to
keep bait alive in small containers.
They are quiet and gentle, but because
their bubbles are typically larger, they
need a greater amount of bubbles for a
large amount of bait.
Air
stone aerators do provide gentle
aeration, but they sustain less bait per
unit of air than aerators that produce
smaller bubbles.
VENTURI
AERATORS
This
is the much copied, old aeration
technology. They can be purchased as a
floating aerator or a bottom aerator
with suction cups.
The
fast-moving water at the output of the
pump creates a vacuum, which suck air
into the pump output. This system
typically provides larger amounts of
smaller air bubbles than previously
discussed aerators.
Some
models damage bait due to the high speed
of water from the pump output.
THRU-HULL
PUMPS
Thru-hull
pumps provide a constant flow of new
water into the livewell and eliminate
the problems of heat and ammonia
build-up. As long as clean water is
available, more bait can be placed in a
given amount of water than with any of
the previously discussed systems.
However, when entering water that is
less than ideal for delicate bait, care
must be taken to secure the intake
water. By utilizing a combination of the
thru-hull pump with other aeration
methods, bait can remain healthy and
lively for longer periods of time.
KeepAlive®
Oxygen Infusion Systems
KeepAlive®
Infusors are new, revolutionary Oxygen
Infusion Systems.
GUARANTEED TO OUTPERFORM ALL OTHERS !
They
might look like the competition, but
their superior technology is completely
different. Air is infused with the water
at the pump impeller. The micro-fine
bubbles produced, are sent gently out of
the pump and into the livewell,
containing life giving oxygen.
KeepAlive®
Infusors
are specifically designed for delicate
shad, greenbacks and white bait.
The millions of micro-fine bubbles are
so small that they remain suspended in
the water longer thus providing more
oxygen for your bait and catch. Our
smallest model will aerate from a
5-gallon bucket up to a 55-gallon drum
or livewell, gently and efficiently. KeepAlive®
Infusors will virtually disappear in a
mass of micro-fine bubbles when used in
salt water.
The
water speed is controlled by it's Air
Control Center to allow fish to school
in a stationary position.
KeepAlive®
