The Manta Microplastics Sampling Trawl Net is designed for sampling microplastics in calm inshore waters and on rivers and lakes. It features a post box shaped aperture and a pair of ‘wings’ bolted onto an inner frame which serve to lift the net frame so that samples are efficiently collected at the top of the water column.
The wings are constructed of 2mm thick marine grade aluminium plate and once bolted onto the main body they are further reinforced by aluminium stiffening bars and a 5mm marine grade stainless steel round bar inner frame. The net is constructed with a strong nylon collar with additional reinforcement along the length of the net, and it is supported within the collecting aperture by the inner frame. A detachable filter bag at the cod end (narrow end) of the net collects the sample and is easily unscrewed for rinsing and sample retrieval.
The net is towed using two stainless steel cables that are shackled to the frame and come together in a coupling ring for the attachment of your own tow rope or cable. The recommended towing speed is 2- 4 knots and sampling should only occur in calm inshore waters, lakes and rivers.
All of our plankton nets are manufactured onsite at our workshop in Devon so if you have a specific size of net or bespoke modification in mind, please contact us (firstname.lastname@example.org) to discuss your requirements.
