Envco – Environmental Equipment

Introducing the suggested Wildco® net for collecting Zebra and Quagga Mussels, often used by the USGS and other government agencies. This 63 micron net is designed to collect veligers, the free-swimming larval form of Zebra and Quagga mussels (Dreissena spp.) These fast-spreading invasive species have been taking over our lakes and streams for a number of years. Because they reproduce so quickly and in such dense configurations, they are interfering with the food chain of our native species and can be easily and inadvertently transferred from lake to lake on boats, nets and clothing.

Keeping track of - and curtailing the spread of - veligers has just become easier. Because a large volume of water is needed to calculate the veliger density using microscopic methods in the lab, our net is extra long with a hefty 1000mL collection bucket. Its impeccable construction can withstand the constant decontamination involved with sampling these organisms.

Veliger Net includes:
• Plankton Net, 1:4 ratio (20” mouth, ~80” long), 63μm mesh
• 7-E50 Ring and Bridle, 20” (500mm)
• 48-D80 Dolphin™ Adaptor, 3.5”
• 47-F28 Dolphin™ Bucket, 1000mL, 61μm stainless steel mesh
• 47-F99 Guard Rails
