WETLAND COLLECTION TOOLS: Bottletrap design details

Collection bottles = These bottles are carefully cut so they

will latch together, with out any other

devices needed to hold them together.

Bottle holder = A plastic part which will hold the

bottle in a horizontal or vertical

position. Place the bottle so the

bottom is held securely. If the holder

is placed too far fore-ward it will

collapse the bottle and the funnel will

come loose.

Clamp = A squeeze on the ends of the clamp

will allow you to move it up or

down the stake easily.

Stake = A 1/2 pvc pipe with a tapered end to

help insert into the bottom and one flat

end with hole to accept the locating

flag.

Flag = An attention getter, as the stakes

tend to get visually lost in the tall

grass.

Artificial substrate = 3 inch dia. pipe 5 inches long, for long

term submergence to allow colonization.

Substrate holder = A special made pipe, clamp, tee, and

spring pin to keep the substrate in

place for extended time periods.

Microscope slide holder = A holder with holes drilled to keep two

slides, back to back, so tightly that

there will be little or no growth

between them. Inhabitants on the slides

can be observed as they grew, without

scraping them off another substrate.

Retriever = A PVC pipe, with a fine screen attached

to the bottom, to allow the artificial

substrate to be placed into them, or the

traps to be emptied into them, which

will allow the water to escape and

retain the contents, with the red

plastic cover. This unit will also make

a good transportation device.

It is a good idea to remove the bottles from the holders, and clamps from the stakes, when not in use to retain their spring.

Note to Users of this device:

At the time of writing this letter, I do not know who will receive them, so I wish to mention a few things which may assist in working with these items.Collection Bottles I find it easiest to put my hand into the funnel, one finger through the hole. Next put the rim of the main bottle in two of the slots and cam or pivot the other two slots into place.

Bottle Holder

The bottle holder should be placed more towards the

bottom of the main body of the bottle, the holder

tends to collapse the bottle if too far forward.

If the plastic screws are tightened correctly the

holder will hold the bottle horizontal, or vertical.

Clamp

A gentle squeeze on the ends will allow the clamp to

be easily moved up and down on the stake. Note that

the clamps are slightly different, between the

substrate holder and the others.

Stake

This stake is not quite as ridged as a wood dowel, but

it easier to clean, and is not affected by water like

wood. Note the hole in the flat end to insert the

locating flag. If you feel that the stake needs to be

stiffer, please let me know.

Substrate Holder

This is several pieces, which will hold the substrate

so it can not come off, however I am not satisfied with

the plastic cloths pin, even though it works.

Microscope Slide Holder

Putting my palm on the outside of the holder and two

fingers inside the clamp, on either side of the plastic

nut, allows me the best control to squeeze the holder

to elongate the holder to insert or remove the slides.

NOTE: HAVE CAUTION THIS IS GLASS. I am sending a couple

of the best slides that I know, but I have found a few

slides which break very easy if inserted improperly.

Hold the two slides together ( they can not be put in

one at a time) set one end into the holes, squeeze the

holder and position the other end into the opposite

holes. Do not release the holder until the slides are

lined up with the holes. This holder has not been used

yet but should provide good viewing of whatever attaches to it.

Retriever

Sized to remove the water and carry the contents of the

bottle traps or the entire artificial substrate. Use

the plastic caps, or some critters will leave. Many of

the bottle bodies will just fit inside the plastic

caps and can be used for small terrariums or whatever.

I would appreciate your comments on the use of these items, what would you like changed and what would you like added.
