About this presentation
  • This is Part III in a series of presentations on
    live foods from the wild.
  • Previous presentations in this series
  • Part I Nutritional value of wild foods. (Sept.
    19, 2010)
  • Part II Where to find wild foods. (Oct. 17, 2010)
  • (Previous presentations can be found at
    http//www.theangelfishsociety.org/PresentationsTA
    SNew.html)
  • The rest of this series will cover
  • Part IV Types of wild foods
  • Part V How to culture wild foods

3
In this presentation
  • Various equipment that can be used for collecting
    wild foods
  • Transporting collected organisms home alive
  • Some health and safety precautions

4
Recap of where to find wild foods
  • Recall from Part II of this series that most
    wild foods are found in aquatic habitats,
    primarily calm water bodies, including
  • Ponds
  • Puddles
  • Lakes
  • Sloughs
  • Rivers and streams in calmer areas along
    vegetated banks

Types of equipment
6
Containers


  • You will need wide mouth jars or other types of
    containers to hold live food that you harvest
    from the wild.
  • You can save up used jars, use wide mouth canning
    jars, round or rectangular glass or plastic
    containers, or just about any type of container
    with a lid.
  • Glass containers are easiest to clean and
    sanitize, but take care if you use glass
    containers because they can break if dropped.

7
Brushes
  • Small, soft artist or paint brushes can be used
    to collect small organisms, such as worms or
    masses of protozoa from the undersides of leaves
    and rocks.
  • Gently wipe the area to gather organisms, then
    dip the brush in a jar of water and swirl gently
    to shake them loose into the water.

8
Eyedroppers, basters, etc.
  • Various sizes of droppers can be used for many
    purposes
  • collecting organisms,
  • sorting them when you get home,
  • transferring them to other containers, and
  • for feeding fish.

9
Nets and sieves
  • Various nets and sieves can be used for
    collecting, as well as transferring to other
    containers when you return home.
  • You can buy nets with various mesh sizes.
  • You can also make your own by sewing cheesecloth
    or nylon hosiery around a loop of wire hangar.
  • For collecting it is best to make the net deep,
    and to make it balloon out to allow plenty of
    surface area to allow water to flow through.
  • A long enough net can be folded as it is removed
    from the water to keep captured critters from
    escaping.

10
Traps
  • Various types of traps can be devised. A simple
    type of trap is to position a net in the water,
    staked in place so the current flows through it.
    When you disturb vegetation or rocks just
    upstream, the organisms are swept by the current
    into the trap.

11
Protective clothing
  • You need to protect yourself while you are doing
    your collecting.
  • Wear a hat or cap for protection from the sun
  • Wear rubber boots if you expect to be wading in
    shallow water
  • Rubber gloves can help protect your hands from a
    variety of possible problems, including scrapes
    on rough rocks, insect bites, leeches, etc.
  • Mosquito repellant. If you are going to be
    collecting in a mosquito-ridden area, put on your
    mosquito repellant before you leave home. Take
    care not to introduce it into your collection
    water.

12
Transporting collected organisms home alive
13
Ice chest or tote
  • If you have filled a variety of containers on
    your collecting trip, you will need something to
    carry them in.
  • As you collect, you want to make sure you dont
    leave your containers in the direct sunlight.
  • A plastic tote or an ice chest can be used to
    hold your collection jars and to keep them out of
    the direct sunlight.
  • Bring something to wrap the containers in or to
    pad the spaces between them so they dont get
    damaged. Use bubble wrap, crumpled newspaper,
    clean rags, etc.

14
Avoid overcrowding
  • Dont try to put too many organisms in a single
    jar. Overcrowding will lead to using up the
    dissolved oxygen very quickly.

15
Keep it short
  • Try to work quickly and efficiently so you can
    get the organisms home as soon as possible after
    collecting them.

16
Keep it cool
  • Overheating will result in depletion of oxygen
    and death of collected organisms.
  • You can keep them cool and shaded in the ice
    chest.
  • You can also bring ice or blue ice along in the
    ice chest to cool your collected items. This
    will help preserve dissolved oxygen, will lower
    the metabolic rates of the collected organisms
    and make it more likely that you will get them
    home alive.

17
A few health precautions
18
Giardia lamblia
  • Giardiasis is an infection of the small intestine
    caused by a microscopic organism (protozoa),
    Giardia lamblia.
  • Be aware that many streams and ponds are now
    infected with Giardia, so you want to make sure
    you dont drink the water. Wash your hands well
    before you handle food or touch your face.
  • You will also want to take care with your
    collected items to avoid potential contamination
    of your aquariums.
  • Other microorganisms may be present in the water
    that can harm your health, such as E. coli.

19
Pollution
  • Be aware that many streams and ponds near urban
    areas may have pollutants that could harm your
    fish.
  • Irresponsible people dump assorted trash and
    other wastes into water bodies, including used
    oil, disposable diapers, old car batteries, and
    other items that may pollute the water.
  • If you have any doubts about a possible
    collection area, then dont risk yourself or your
    fish.

20
Use good safety precautions
  • Be careful about wading into a stream or pond.
    People may have disposed of sharp pieces of
    metal, broken glass, or other items that can
    injure you.
  • Watch out for algae-covered slippery rocks to
    avoid slipping and falling.
  • Depending on where you go, you may need to watch
    out for wildlife, such as moose protecting their
    young, or bears.

Final thoughts
  • I hope you enjoyed this presentation, and that it
    gave you some ideas for how to prepare for a trip
    to collect wild foods.
  • The next presentation in this series will talk
    about how to identify different organisms that
    you find during your collection trips.
