The Canadian Aquatic Biomonitoring Network (CABIN) is the national biomonitoring program developed by Environment Canada to provide standardized sampling protocols and a recommended assessment approach called the Reference Condition Approach (RCA) for assessing aquatic ecosystem condition.

CABIN is a collaborative program for the collection and assessment of biological data to determine the health status of aquatic ecosystems. Maintained by Environment Canada, CABIN provides participants with a nationally standardized protocol for the collection of benthic macroinvertebrate and stream information that is shared across the network using online tools. Collaborating with other agencies and organizations (both public and private) allows all participants to evaluate aquatic ecosystem health in a scientifically defensible manner at a fraction of the cost of doing so individually.

Benthic Invertebrate Sampling

What is a kick net?

CABIN uses a kick net sampling method standardized by sampling effort (i.e. time – 3 minutes). The kick net is a triangular metal frame holding a mesh bag of 400 micron size (Figure 16) with a collection cup at the end. One end of the metal frame is attached to a rake handle.

The part of the bag that attaches to the frame is made of canvas or ripstop-plastic tarpaulin to withstand abrasion. A detachable cup can be added to the end of the bag to facilitate removal of the sample. A 400 micron mesh net is recommended for general sampling.

Bythotrephes Net

Our nets are custom made with the finest materials available. In most situations, knotless nylon mesh is used to reduce abrasion on the fish. Let us know what your requirements are and we will build a net tailor made to your specific water or fish conditions. All nets may be treated with an UVB coating to prolong their life.

Seines are available in mesh sizes from 1/8″ to 1/2″, in 4′, 6′, 8′ and 10′ heights(some mesh will require horizontal seams to achieve 10′ height). Sienes are attached to 3/16″ braided poly rope and may be ordered with weights and floats as well. Trap (Fyke) nets are very effective at trapping fish alive and unharmed. As shown the basic design consists of 2 steel frames, 4 to 5 steel hoops, and 1 or 2 throats. Frame size can vary from 27″x39″ to 4′x6′. Mesh sizes range from 1/8″ to 1″.

Hoop nets normally come with 7 steel hoops, with throats in the 2nd and 4th hoop. Mouth diameters can range from 2′ to 5′, with mesh sizes up to 3″.

Dip Nets

D-FRAME AQUATIC DIP NET
Ideal for sweeping over vegetation or use in shallow ponds or streams. The ring is made of rust-resistant powder painted steel, and is securely and easily attached to the hardwood handle using a threaded socket connection. Available in a variety ofmesh sizes in either rot resistant NITEX mesh or polyester netting.

Maintenance Charger

Electrofisher Batteries must be used and kept at or near full charge to ensure longevity.  Our Maintenance Charger allows you to store and trickle charger up to 4 batteries for those long winter months when your equipment may not be in use.  Nothing shortens the life of a battery better than allowing it to discharge completely.  An investment in a maintenance charger will pay off in the long term.

Gloves

Various Gloves available upon request.
Minimum Order Required. Please Call for details

Eboat:   We are very pleased with the results of the testing of our EBoats which have exceeded our expectations! Please see a full explanation in the Press Release section of the website of how our technology works and the reasons why we went this route.

We have also adapted our popular HT2000 Backpack System to easily work in small vessels and tote barges to enable more versatility of operation.  No other system allows this kind of flexibility.  With today’s budget restraints, Halltech has paved the way for making your research and management dollars go further.

We are open and willing to configure our systems for almost any application.  Please call 866 425-5832 ext.24 for pricing.

Our TEB or Towable Electrofishing Boat is suitable for bodies of water that may be inaccessible to conventional boats and trailers.  Because the wheels are integrated in the hull of the boat, it can easily be launched in only 8” of water.  The wheels are then retracted into the hull for excellent maneuverability.  The flat bottom design and perfect balance over the axel also allows launching over pond embankments for private fish farm surveys.

All Electrofishing Components can be removed in minutes, easily converting this vessel into a Multi-Purpose Work Barge or Net Boat.

This dredge is useful for sampling benthic communities inhabiting soft bottomed aquatic environments. As the dredge is lowered, the hinged upper doors swing open, allowing water to pass through and minimize the shock wave. When the dredge reaches the bottom, a messenger is sent down the line which trips the spring-loaded jaws. The jaws snap shut, preventing washout of the sample. Our dredges are constructed of stainless steel with special Heliarc welding for extra strength and trouble-free life. A simple cable release system with convenient bar grip enables the operator to set the dredge with greater safety. The Ekman Dredge comes complete with a stainless steel messenger and 100ft (30.45m) of line and carrying case.
