The video above is one of the best for both duckweed and string algae.
String Algae may begin to grow in your system. It's not all bad because it can be useful as a fish food, but it tends to clog the system. If your fish don't keep it under control a small amount of salt in the water will kill the string algae.
There are many varieties of duckweed. I have two, but one or the other will tend to prevail depending on the time of year. Duckweed can be rinsed and used in salads and it provides good protein for your fish. Under ideal conditions duckweed will double it's volume in just a few days, but you will probably have to raise your duckweed separate from your fish because they will eat it faster than it reproduces.
Duckweed cleans the water, but it can also exclude oxygen if it grows too thick. It prefers warm water, and seems to grow out of control when the conditions are right. Creating the right conditions can be difficult, so I spread it around various areas and let it grow where it wants to grow.
I scooped up some of the living scuds and watched as they scurried
about in the diminishing puddle of water in my hand. They nuzzled
into the darkness between my fingers and I learned two important
lessons about scuds. First of all, swimming scuds, the kind fish
are likely to see, are as straight as a needle and only curl up
into the typical scud fly profile when they are crawling around
on something. The second lesson learned was that I liked these little
guys.
Typical greenish scud clambering over a rock
in a Truckee creek.
Since then I’ve spent an embarrassing number of hours underwater
watching scuds and watching fishermen try to trick fish into eating
scuds. For those moments I can’t be on the water, we have
an aquarium in our kitchen that has become home to countless generations
of scuds.
Like crayfish, shrimp, and sowbugs, scuds are Crustaceans. They
belong to the order Amphipoda which contains three families. Gammarus
and Hyalella are the families of greatest importance to flyfishers.
Like insects, scuds periodically shed their exoskeleton but unlike
insects, scuds don’t have nymph or pupal stages. Baby scuds
look like their adult counterpart, only cuter. Scuds require a relatively
large amount calcium to support their molts. Scuds are found almost
exclusively in alkaline waters and where ever they are found, trout
actively seek out these nutrient rich packets of energy. In scud-rich
waters such as Eagle Lake, I’ve seen trout bellies distended
by hundreds of scuds. To offset such intense predation, scuds are
remarkably prolific.
Scuds populations have been measured as dense as 10,000 creatures
per cubic meter of water. A single pair can spawn half a dozen times
in a year and produce 20,000 young. The single largest threat to
scud populations is the rapid drawdown of tailwaters below dams.
On one scud laden Truckee River tributary, it is common to find
windrows of dead and dying scuds when the river flow is abruptly
cut. These normally light olive scuds turn bright orange when they
die and trout in this creek are quite color selective when flow
patterns change.
This scud is nearly dead, stranded
in a puddle created by an abrupt dam shut down. When the dam
reopens, the trout in this Truckee River tributary feast on
the dead scuds that get swept downstream. At this time the fish
won't eat a green scud pattern.
Scuds are generally reported to be herbivores and scavengers. Our
pets are vicious predators. They will dart from cover to attack
tubefix worms and will even tackle small backswimmers who in themselves
are pretty lethal creatures. Scuds can easily overpower Siphlonurus
mayfly nymphs seven fold their weight and we have witnessed scuds,
sometimes in groups, attacking and killing tadpoles.
Though scuds live in the shallowest margins of lakes and streams,
they intensely dislike light. They typically hide in deep cover
while the sun is shining but quickly come out to forage when the
skies dim. I’ve watched fish boiling through masses of scuds
as they rose out of Elodea mats when afternoon cumulous clouds melted
shadows across the lake. As soon as the sun broke through the clouds,
the scuds would vanish and the melee would cease. Under overcast
skies, scud patterns will very often outfish "normal"
nymph and pupa patterns.
Scuds have seven pair of legs, the first two are used for grasping
and manipulation while the other five pair propel the bug with synchronous
ripples. When swimming they stretch out completely straight (curved
scud patterns not only look wrong when stripped through the water,
they have poor hooking ability) and the scud bends into its characteristic
curled position when it scuttles about along the streambed or among
the vegetation.
When scuds swim they become a blur of buzzing legs, whisking antennae
and fluttering gills; they travel upside down as often as not. There
is no such thing as a good scud imitation. Don’t even try
to fool an educated fish into believing your hunk of Visqueen and
feathers is the real thing. The occasional trout might eat it, but
only because he’s greedy.
This is my second bag of Gammarus shrimp AKA, Scuds. They are good for live freshwater fish food, eat debris and multiply quickly.
I'd highly recommend psilocyborg69 on e-bay. He does a good job of packaging, and when I had trouble with the first order he quickly sent this second bag.
by Roger R. Locandro (Weeds Today/Early Spring 1982)
Dr. Roger R. Locandro, is Professor of Agriculture and Natural Resources and Dean of Students at Cook College, Rutgers
University. He is a weed ecologist and teaches a unique course in interesting and edible plants. The course is followed by a
sequel "Interesting and Edible Meats." His experiences are an accumulation of a long,
traditional, ethnic heritage, fine tuned
by his weed science degrees and his continued interest in teaching.
Exquisite cuisine can be discovered in the wild world of weeds. Some of the finest tasting,
most succulent vegetables remain virtually untouched in fields and roadside areas. Americans
have generally abandoned the European/Oriental tradition of the utilization of edible and
medicinal wild plants. Standard of living appears to play an important role relative to direct
dependence or even interest in wild things. As the standard of living increases, people rely more
and more on specialized groups of people - farmers - to produce food.
Half of our family originated in a little town in the hills of Sicily and half from the
Netherlands. Sicilians are grand masters of plant and fungi taxonomy and "culinary" economic
botany. They know what's good, interesting and edible! Sicily is a mountainous, rocky island in
the semitropics off southern Italy. Steep-walled valleys, covered with a thin mantle of soil,
surrounded by a marine environment, are the basis of the Sicilian agrarian/fishing economy. The
soil and geology is such that much of the farming is only subsistence level. Families make every
inch and every plant count. While the Netherlands is a considerable contrast, the older European
wild plant traditions are still evident.
Teaching weeds with an "interesting and edible flavor" unlocks excitement, interest, and
motivation in all students, young and old. The opportunity to teach weed taxonomy, ecology,
biochemistry, etc., through the medium of interesting and edible plants, with an ethnic twist, has
proved to be very successful. From an infinite population of plant species, I have selected five
plants and will claim that they are unbeatable for table fare. Most of the species are easily located
and harvested.
1. Dandelion-Taraxacum officinale
2. Pokeweed-Phytolacca americana
3. Greenbrier-Similax rotundifolia
4. Lambsquarters-Chenopodium album
5. Burdock-Arctium minus
Dandelion
In New Jersey we start picking tender, succulent dandelions on southern slopes in early
March. Dandelions are ubiquitous and can be found almost anywhere in the world. The rest of
the world relishes this wild treat. In Italian we would say "chicoria," somewhat descriptive of the
chicory-like leaves of dandelions. An interesting note is the constant increase in the production of
domestic dandelions in vegetable growing areas of the United States.
What do you do with a dandelion? Eat it fresh in salad, use it as a vegetable, a main
course, or drink it! The youngest plants - those without flowers - are prime. They make the best
salad with a dressing of your choice. Dutch style provides a hot dressing of chopped bacon bits,
bacon drippings, sugar and vinegar to taste. The hot mix is simply poured over freshly cleaned
dandelions and blended together.
As we move from the fresh product, an important lesson is worth learning. Steam, do
not
boil, vegetables. Boiling effectively removes large quantities of water
soluble vitamins and
minerals. Steam helps to preserve the nutritional qualities, along with
the fine, delicate flavors
and textures. Steam the dandelion greens until tender and serve as you
would domestic greens -spinach, Swiss chard, etc. The difference here
is that the dandelions are fresh, free, and they don't
come in plastic bags!
Now for the Sicilian treatment. Take the drained, steamed dandelions or any other green
that you wish to use, and cut them into half -inch pieces. Mix them with just enough beaten egg
to hold the greens together. Add your favorite Italian grated cheese to taste and a touch of finely
chopped garlic. Form hamburger-like patties with a large spoon or with your hands. Fry the
patties in olive oil. Drain. Here is another good tip: always drain fried food on a cake rack for a
nice dry all-over texture. My only problem is not being able to cook enough dandelion cakes for
my family and students. This style, or cuisine, is reflective of Sicily. Limited quantities of wild or
garden vegetables, combined with small quantities of eggs and cheese, are artfully stretched to
provide a balanced meal for a family.
If you are planning to eat dandelion greens, fresh or raw, harvest only up to the flowering
stage. Plant chemistry changes considerably when the flowers are in bloom. But don't stop now.
Wait for full bloom, and begin the dandelion wine process. The wine is made from the golden
blossoms. The following recipe is from the Dutch side of the family. They settled in New Jersey
over two hundred years ago.
DANDELION WINE
10 quarts blossoms, no stems
15 quarts water
Boil water, add blossoms and remove from heat. Allow to stand overnight. Next day simmer for one hour. then
strain and retain only the liquid.
Add ten pounds of sugar, eight
sliced oranges, eight sliced lemons, two pounds of raisins. Place in
large crock or
plastic container. Ferment for nine days. Stir twice a day. Place in
bottles or jars until fermentation is complete. If the first
fermentation does not begin within one or two days, add a cake of
bakers' yeast or dry yeast.
Do not seal the jars at this point. After the second fermentation has stopped in the jar or bottle (the time interval
depends on the temperature of fermentation), remove sediments by siphoning off the liquid into clean bottles. Again, allow the
bottle cap to remain loose until no further fermentation takes place. Seal the bottles, store away, and
prepare for some old
"medication"!
Burdock
Burdock starts to grow in early May in New Jersey. The plant is characterized by large,
rhubarb-like leaves and edible stems and roots. This is another plant species enjoyed by the rest
of the world. in Africa it is known as "gobo." To Italians it is "cardone." The best part is the
young, succulent stem. Don't eat the leaves. Try the roots. . . they're okay as a steamed
vegetable but not as good as the stems. Cut the stems into half-inch pieces and steam until tender.
Proceed to use the Sicilian formula with the eggs, cheese, garlic and olive oil. You may also
enjoy burdock in stews, soups, or served as a cooked vegetable.
Pokeweed
I predict that pokeweed will be completely removed from the wild scene when discovered
as a good vegetable. Prepared and served as asparagus, and alongside of asparagus, people will
select pokeweed almost every time. The highly succulent, tender, sweet shoots are harvested in
the early spring. Pick the shoots up to eighteen inches in length. Strip off all the leaves beginning
at the base. Stripping downward removes some of the outside cuticle in the process. Retain the
leaves in the whorl at the tip. Cook them along with the stems. if you say pokeweed is poisonous,
you're right. The plant contains an alkaloid - phytolacin. Fortunately, the alkaloid is highly
soluble and can be easily extracted from the plant tissue. The alkaloid is generally concentrated in
the roots, fruits, and leaves and, to a lesser extent, in the stems and young shoots. Cut the
prepared shoots into two-inch segments and - break a rule - boil for thirty seconds. Pour off the
water and proceed to steam until tender. Serve as you would asparagus, as a vegetable, in soups,
or try the Sicilian treatment.
Lambsquarters
Lambsquarters is probably the closest relative to spinach only it's better! Taste tests
continue to indicate a high preference for lambsquarters over spinach. Steam and serve. In New
England, lambsquarters is canned for winter use. Pick out only the young shoots or allow a
couple of large plants to grow and continue to harvest the new side shoots. The more you pick,
the more lateral budding is induced.
Greenbrier
The best is saved for last - greenbrier, Rapidly growing vine tips are harvested in the
spring and summer. Snap them off the ends of the vine with your fingers. They will crack where
the tender shoot extends out from last year's woody tissue. Serve as a hot vegetable, add fresh to
a lettuce salad, or use the "treatment." This is another Italian delicacy, also known as "rauni." it's
hard to believe that such a fine, delicate treat as similax comes from a thorny, green bramble
tough enough to be used as a cattle fence.
Not all weeds taste good or are pleasant textured. And be very cautious to avoid plants or
plant parts that are poisonous. We spend little time foraging among the sticks and stones and
concentrate on the many good and edible plants.
An extended list of eating delicacies include the highly underutilized wild onion, Allium
vineale; chickweed, Stellaria media; yellow rocket, Barbarea vulgaris; watercress, Nasturtium
officinale; day lily, Hemerocallis fulva, and many others.
Your introduction to edible plants may serve as an entryway to an exciting, dynamic
career in plant sciences. From the fields and byways, the classroom and laboratory ... bon apetit!
Purslane contains more omega-3 fatty acids (alpha-linolenic acid in particular[4]) than any other leafy vegetable plant. Research published by Artemis P. Simopoulos states that Purslane has 0.01 mg/g of eicosapentaenoic acid (EPA).
This is an extraordinary amount of EPA for a land-based vegetable
source. EPA is an Omega-3 fatty acid found mostly in fish, some algae,
and flax seeds.[5] It also contains vitamins (mainly vitamin A, vitamin C, and some vitamin B and carotenoids), as well as dietary minerals, such as magnesium, calcium, potassium, and iron. Also present are two types of betalain alkaloid
pigments, the reddish betacyanins (visible in the coloration of the
stems) and the yellow betaxanthins (noticeable in the flowers and in the
slight yellowish cast of the leaves). Both of these pigment types are
potent antioxidants and have been found to have antimutagenic properties
in laboratory studies.[6]
100 Grams of fresh purslane leaves (about 1 cup) contain 300 to 400 mg of alpha-linolenic acid.[7] One
cup of cooked leaves contains 90 mg of calcium, 561 mg of potassium,
and more than 2,000 IUs of vitamin A. A half-cup of purslane leaves
contains as much as 910 mg of oxalate, a compound implicated in the formation of kidney stones, however, note that many common vegetables, such as spinach, also can contain high concentrations of oxalates.
When stressed by low availability of water, purslane, which has
evolved in hot and dry environments, switches to photosynthesis using Crassulacean acid metabolism (the
CAM pathway): At night its leaves trap carbon dioxide, which is
converted into malic acid (the souring principle of apples), and, in the
day, the malic acid is converted into glucose. When harvested in the
early morning, the leaves have ten times the malic acid content as when
harvested in the late afternoon, and thus have a significantly more
tangy taste.

Those nasty weeds, always
complicating our lives and making more work for us than what we desire.
Weeds are bad…..right? Well, not all of them. Simply put, the
definition of a weed is “a plant out of place.” It’s good to think of
them that way because some of those plants are edible and very healthy
for you! So, it’s really not a bad idea to learn about weeds and their
effects on your diet as well as their effect on your garden. Let’s take
a look at some common weeds that you probably have growing in your
garden.
DANDELIONS.
Believe it or not, these critters are beneficial weeds! They are
edible, and can be found usually in salads. They are beneficial because
they add good minerals to
the soil. They attract pollinating insects, and release ethylene gas,
which helps fruits to ripen. Dandelions also have been used as medicines
for such ailments as infections, liver problems, and cancers.
MORNING GLORY.
Does this plant have any uses? It is on the Federal Noxious Weed list,
and technically it is illegal to grow, import, sell, or even have in
your possession. It is edible, being known in southern states as water
spinach. The Morning Glory grows fast and tolerates poor, dry soils.
Some species vine, and are used for creating shades on building walls,
helping to reduce heating and cooling costs. The roots do have minerals
which can be returned to the soil when composted.
CHICKWEED.
If you have chickweed growing in your garden, it is a good indication
of some very good soil. This plant has a tendency to accumulate some
great minerals such as potassium and manganese, which return to the soil
upon decomposition. They are edible, commonly being used in salads.
CLOVER.
This plant indicates low fertility in your soil, especially low
nitrogen levels in the soil it grows in. It is used a lot as a cover
crop. Farmers will use clover to help control soil and water quality,
weeds, pests, and diseases.
DOCK.
This weed indicates a poorly drained soil that is becoming acidic. Some
species are nuisance weeds, but others are edible. There are not that
many known uses for this particular plant.
HORSETAIL.
This weed is widely known as a nuisance weed. It is difficult to get
rid of, even after pulling it out as it grows deeply into the ground. It
grows in poor, acidic soil. However the Horsetail does accumulate some
good minerals which go back into the ground when it decomposes.
Increasing the PH level in your soil will do a lot to get rid of this
pest.
VETCH
This plant also indicates a poor soil that is low in nitrogen. Like
some of the other weeds, it does accumulate some good minerals which go
back into the soil. It is a plant that is occasionally used as a cover
crop also. There are no other good uses for this particular weed.
QUACK GRASS.
Not much to say about this particular plant. It is hard to get rid of
because of the creeping rhizomes (underground root system) which allow
it to grow quickly. Quack Grass is usually considered an invasive weed. A
sick dog will dig it up and eat the roots to cure its ailments. It has
been used in herbal medicine since the time of the Greeks.
THISTLE.
This particular weed usually is found in compacted soil. Butterflies
like these plants. The Thistle is the national emblem of Scotland. It is
also the emblem of Encyclopedia Britannica, which originated in
Scotland. Other than that, no medicinal uses and you surely do not want
to eat it!
SORREL.
Yet another type of weed that exists in soil that is acidic and low in
lime. The leaves of this product can be found in soups, salads, and
sauces. In little quantities, it is harmless for human consumption.
However, if a person ingests too much of this weed, it can be fatal.
Oxalic acid, which is a poison, is found in Sorrel; thus, the reason why
a large quantity can be deadly to the person eating it.
PLANTAIN.
Here is another one of nature’s products that is found in acidic,
compacted, and low fertility soil. This plant has been used since
prehistoric times as an herbal remedy. Other than that, not an item you
want to find in your soil.
Make sure you are careful if you are
thinking about eating the plants that are listed as edible. There are
many species of each plant, and you want to make sure you are eating the
right one. Talk to a master gardener or well experienced produce person
to get the right answers. You know the saying “if you can’t beat ‘em,
join ‘em?” In this case it’s more like “if you can’t weed ‘em, eat
‘em.” Just section off a part of your garden and grow some of these
pesty weeds. Nurture them along with some water during the hot months
and you’re all set. Happy gardening!
My goal is to grow plants that will clean the water and provide food the fish will eat.
Even if I must grow these plants outside of the fish tank I believe it would be an asset to grow live food for the fish.
I think the fish will really appreciate this live source of food, but big fish may uproot,and destroy the plants so setting aside a special grow bed will probably be necessary.
The
vegetables will of course be the intention of my system, but putting
aside an area for eatable plants the fish will enjoy seems like a good
investment in their health, and an economic solution to fish food.
While watering my compost pile I noticed a lot of Black Soldier Flies.
These flies are prized for their larvae, and many people raise them for chicken and fish food.
They
are extremely beneficial and will help decompose compost very quickly.
They will also help to keep pesky House Flies away and will not bother
people like House Flies
Soon i will build a Black Soldier Fly barrel and begin to raise the larvae for my fish.
Along the same lines is this house fly composter. At first you might ask why would I want to attract house flies. But if the chickens are eating virtually every maggot they will not survive long enough to reproduce. In fact the chickens will also eat flies.
My neighbors dogs are responsible for the flies, this is another way to control the populations.
