Ruins your
day to get up at 3 in the morning to go Striper fishing, only to find that all those
Shad
that you caught the day before, are now spinning around belly up. Your fishing buddies are
on the way
and you have No live shad! Kind of gives you that "Why
did I get into this mess feeling".
Been there - wore that tee-shirt. I've killed shad every way known and
invented a few.

A shad has to be one of the most sensitive critters alive.
If you put them
in a container that has corners
without the perfect environment, they will swim to
the corners,
push their noses in it until they
use up the oxygen in that corner and die.
You need a round or oval tank with a pump to circulate the
water with an oxygen induction system.
Use a good water conditioner.
Swimming in a circular motion helps the shad pull oxygen through their
gills.Keep the water flow slow, In some cases, excess water flow will force the baits to
swim too hard and consume even more oxygen
Cool bait is better bait!
I had read that if you keep your bait cool in the summer it will
last longer because cool water holds more oxygen than warmer water so the bait will not
stress as much.
Seems like a bag of ice might do the trick!
With confidence in my new found information, in goes the ice.
Not a bad idea.
I added the
ice to the tank slow so that the temperature didn't drop too fast.
(( Caution: Don't change water
temperature over 5° at a time)) .
Now those shad would "have to last the night"
I thought.
Well the next morning, you guessed it, dead shad.
After all that ice, my new temperature
probe!
How could this be?
You know, that stuff in city water that they use to clean the bacteria from the water
before you drink it called Chlorine, Works real good to kill shad too! It's in the
ice!
I was chlorinating them! It never occurred to me. That's the same as bleach.
I'd never put bleach in the tank!!!
The answer to this problem is to add "chlorine remover" to the water before
you add the ice.
Also you can take your own treated water, freeze it in
containers and drop in your
bait tanks.
Another way to solve this is to forget the ice when your out on the lake.
Most lakes have
all the cool water you need right there for the taking.
It's about 15 to 35 feet below the
surface.
The
Thermocline.
In the summer if I need cooler water for my tank I take along a garden hose that I
attach to a
12v pump that brings the water up from the thermocline.
No chlorine! No
ice! Just cool water that is right out of the lake anytime I want it.
Using a bait tank
that is insulated helps retain the temperature.
Bad word: "Ammonia"! Ammonia is produced by the shad when they deposit their "waste" in you bait tank. Water changes will help prevent this build up. If you can't change the water, pet shops sell a product called "ammoniasorb". It helps the bait by absorbing some of the ammonia out of the water that would otherwise build up in your tank. It looks like little white gravel chips. I put a scoop of it in a cloth bag and rinse it in the lake a dip or two to remove the powder that covers it. The bag I use is made is made of mom's old panty hose.
Foam on the surface
If your tank is foaming it is a sign your bait water is
out of Balance.
The below methods are for short term help only.
Foam is normally caused by ammonia build up.You want the water in your tank to mix with the air above it.
If there is foam
floating on the top of the water it will prevent the air from transferring oxygen to the water.You
can use a powered dairy creamer if you must and there's also a product called "foam off". The best cure is changing about 1/2 of the water in you tank
and find out
the problem.
Adding salt to the water will help by hardening the scales on the
shad.
Don't go crazy with it. Add about a cup to 25 to 30 gallons.
I've been buying
water softener salt in 5# bags from a farmers co-op, its cheap. Make sure the salt is not ionized or contains an anti caking chemical.
These few little "tricks" will help you keep your bait frisky. You want the best bait that you can get hanging on that hook you put down. A half dead shad just will not do it. You want to have healthy, happy, shad in your tank which in turn will result in great fishing!
Stressed shad don't act normal.
Once you've gained experience with shad you'll learn how healthy shad act. Stress is a condition that causes physical or mental
discomfort that results in the release
of stress-related hormones or results in specific physiological responses.
For example, stressful events will cause an increase in heart rate,
blood pressure, increased blood sugar, and the release of cortisol.
Stress can be physical or environmental.
Stress can either be short and sudden, or long and chronic. long-term stress or severe, short-term stress contribute to death in
shad.
Red nose
Excessive lose of scales
Clamped fins
Visible spots, lesions, or white patches
Shad gasping at the surface of the water
Elevated ammonia, nitrite,
and nitrate all create deterioration in shad due to stress.
High levels can cause severe stress, whereas slightly elevated levels can
contribute to chronic stress.
pH levels that change abruptly cause acute stress and continually elevated or lowered pH levels can cause chronic stress. Chronic stress is often not visible. It can take weeks and months to develop. Shad can adapt to long-term changes, but there are limits. PH changes of more than 1.5 points below or above recommended levels are going to have a negative effect over time and should never be considered acceptable.
Temperature fluctuations are a much underappreciated stressor of fish. Shad do not tolerate temperature changes very well. You should never change water temperature by more than 10 degrees. Preferably 5 degrees. A 10 degree temperature rise roughly doubles the rate or speeds of many chemical reactions in the water environment. Cooling a system down by 10 degrees slows down the rates of such reactions by a similar factor.
Shad live within very specific salinity levels (levels of salt in the water). Their bodies work hard to maintain the absorption of Water and Electrolytes between themselves and their environment. If their environmental salinity is not specific to their needs and is not held at a steady level, they have to work harder to maintain their absorption of Water and Electrolytes, which generates chronic stress.
Oxygen levels that are below recommended levels can cause fish to 'breathe' faster than optimum and this can result in chronic stress. Obviously, very low oxygen levels can lead to severe short-term stress and death.
Overstocking of the tank
is a problem that contributes to a lot of stress, from water pollution to
oxygen depletion.
Do not overstock your tanks.
If you want to stress your fish, put too many in the tank and it will happen
every time.
A good number if your keeping shad in a storage tank is 1 shad to 3 gallons
of water.
With a good boat bait tank with proper environment a 1-1 ratio will work for
short periods of time.
If you add water condition or medications, make sure you know you are using the correct chemicals and the correct amount.
Nothing stresses shad more than transporting from the
wild.In just a few hours, the shad will be netted, sorted, netted, held,
transported, netted and so on
through the catch and final release to your holding tank.
Throughout this process they may be exposed to drastic changes in
temperature, ammonia, pH, salinity, medications etc.
If they are not handled carefully and are not placed in an optimum
environment, their stress is going to continue and they will die. The
majority of shad mortalities occur at or near the time of entering a new
tank and only through an appreciation of stress and its effect on them can
this problem be prevented.
While it is impossible to eliminate all stress,
fortunately we have the ability to limit or prevent many of the causes.
Acute stress is more obvious and needs to be addressed very quickly.
Chronic stress is often not visible, It can take days to develop.
If your shad appear to be doing fine, until one day they die there is probably a source of stress that needs to be identified and
remedied.
Stress is one of the most critical factors in shad keeping.
Only by understanding the effects that stress have on shad,
as well as being able to identify and prevent common stresses,
can we eliminate and treat the stress problem.
Temperature of natural waters is an important factor for
aquatic life.
Each creature is adapted to particular temperatures since fish and other
aquatic life have no control over their body temperatures. Water temperature
of 95F is considered the maximum for most aquatic life.
Trees and brush provide shade for natural waters such as creeks, ponds, and
lakes.
When these areas are cleared for construction, the temperature of the water
may be raised due to the increase in sunlight on the once shaded area. Changes in water temperature can affect aquatic habitats.
This may result in the death of many aquatic creatures.
An important gas in water is oxygen.It is referred to as dissolved oxygen or DO. Oxygen is necessary for aquatic life. DO is found in cold water at higher levels than warm waters because oxygen is more soluble in cold waters. Cold waters have a DO measurement of 5.0 mg/L or higher.Oxygen is found in warm water at not less than 4.0 mg/L. Different organisms require different water temperatures and DO amounts. Some examples include carp, which is a warm water fish and lives in water with as little as 3 ppm of oxygen, while largemouth bass require 5 to 8 ppm.
The pH indicates the amount of hydrogen ion concentration.
The acid, neutral, or alkaline nature of materials can be determined by
using a pH test.
Natural bodies of freshwater should have a pH of 5.0 to 8.5.
Seawater has a pH content of 8.1.
An acid level of less than 5.0 indicates that mine drainage or acid
industrial waste has polluted the water.
Industrial alkaline wastes are indicated when the pH is 8.5 to 9.0.
A neutral pH of 7.0 is considered best for human consumption.
Nitrogen (nitrates) are found naturally in bodies of water
at low levels. It is essential for plant growth.
Pollution is present when nitrates are found at excessive levels.
Nitrates are found in fertilizer, sewage, industrial, and livestock
wastes.
High levels of nitrates when paired with phosphates can stimulate the
growth of algae causing fish kills.
A nitrate reading of 0.1 ppm is considered normal; however, it is possible
that due to the water source, or sensitivity of the test, a reading of zero
may occur.
Phosphorus (phosphates) is found naturally in bodies of
water.
It is a nutrient for aquatic plants and is generally found 0.1 ppm in
natural waters.
When phosphorus levels increase, it is a sign that agricultural wastes or
wastewater has polluted the body of water.
Several detergents include phosphates (dishwashing and clothes washing
products).
The phosphorus increases algal growth which increases oxygen levels from
photosynthesis.
Several cloudy days in a row can result in the algae dying.
Oxygen is used in the decomposition of the algae resulting in fish kills due
to a lack of oxygen.
Copper salts enter natural waters from industrial waste.
These salts are used in electroplating, photography, textile manufacturing,
and pesticides.
A concentration of 0.015 to 3.0 ppm can be harmful to aquatic life.
Copper salts destroy growths of algae which can deplete oxygen supplies.
Feeding Shad
Shad feed primarily on zooplankton, Plankton feeders can be tricky to feed, the key thing being that they need multiple small meals per day to do well. Shad are the classic example of plankton-feeding fish. I have used PhytoPlex Phytoplankton from Kent Marine
