LaMotte KICK-NET 3-0021-P - Manual

KICK-NET IN STRUC TIONS
3-0021-P
This 1 X 1 meter square 500 micron white mesh net is designed to meet the
requirements of groups performing USEPA Rapid Bioassessment Protocols
for benthic invertebrate sampling. However, any group interested in
sampling their streams for benthic invertebrates can easily use this net.
If you purchased the kick-net only, the pole sleeves will fit poles no larger
than 1 1/4 inch in diameter. Poles can be purchased at most hardware stores
that sell closet rods or pvc pipe and should be 4 feet long.
The bottom seam has been constructed to allow for the attachment of a
chain to the bottom of the poles. The chain will provide the weight needed
for the net to lie on the stream bottom. The chain should be galvanized and
this suggested size: 2/0 twist-link, machine chain with a 520 pound working
load limit. Chain length should be 43 to 43 1/2 inches. It can be attached to
poles using a washer and a stainless steel wood screw or swivel hook.
STOR AGE AND CARE
Keep sharp-edged objects, such as sticks, stones, etc. away from the mesh
net to avoid damaging it.
After use, completely air dry the net before storing.
NET USE
The following are general directions for use of the kick net. Contact local or
state natural resource departments, or other monitoring groups, for their
recommendations on site selection and location, net use, collection of and
guides for identification of local species and assessment. Obtain any permits
that may be required for collecting aquatic organisms from your state
agency.
Besides the net, suggested additional equipment should be used with the
kick net, including: rubber gloves and boots or waders to keep hands and
feet protected, white collecting pans, forceps or tweezers, magnifying lenses
or boxes, buckets, preservative and sample jars (labeled with date, site #,etc.
before going into the field).
The sampling site and sampling area in the stream should be selected prior
to sampling. Sampling should take place in a riffle area where the stream
flows swiftly and the substrate (stream bed) consists of rocks and stones.
Sampling in riffles can ensure a good diverse sample of benthic
invertebrates as riffles provide good habitat, including plenty of oxygen (via
water turbulence) for these organisms.
