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.
1. Enter the stream upstream from where the net will be placed, and sample at the most upstream portion of the riffle so as to not to disturbed the substrate in areas downstream that may need to be sampled.
2. Hold the net perpendicular to the streamflow at a 45 % angle, letting the water flow into the net (see diagram). The bottom of net must be anchored slightly below the substrate to prevent insects from escaping beneath the net.
Contact your US EPA Regional Office or State Agency in charge of water quality sampling.

3. While one person holds the net, a second person picks up each stone (at least several inches in diameter)in the sampling area and “cleans it”. Holding the rock below the water’s surface in front of the net, scrub the entire rock surface with your fingers to dislodge all insects which will collect in the net. Check each rock to be sure the surface is free of all organisms and replace in its original position. Continue until all rocks have been scrub in the designated sample area usually a 3 foot square or 1 meter square section (same dimensions as the net).
NOTE: Avoid standing in the sampling area when scrubbing stones.
4. After all the stones have been scrubbed, kick, shift and stir the substrate with your feet. The entire sampling area must be done. This action should take no less than 1 minute but could take longer, if needed.
5. Remove net from the stream. The person who scrubbed the stones should grab the bottom of each pole, and in coordination with the person holding the net, lift the net from the water with a scooping motion toward the streamflow. Do not allow the top of the net to go below the surface of the water, otherwise, you may loose part of your sample. Carry the net to a pre-selected streambank or streamside area for insect removal, identification and sample collection.
6. Wash the net in the stream to remove any remaining insects or debris. Completely air dry net before storing.
