For sampling the plankton in static or slow-flowing water . 250mm and 300mm Plankton Nets can be hand thrown or towed but a full risk assesment should be undertaken prior to use. Plankton nets have a ring manufactured from 5mm marine stainless steel with a towing harness and 7m of line attached. The collar is sewn directly to the net and ring reducing the amount of sample loss and is made from industrial nylon. The bags are manufactured from precision mesh of your specification. The most common mesh ordered is 250micron for zooplankton and 53 micron for phytoplankton.
Our nets can be adapted to take a digital flow meter in the mouth. This meter and its software will give instant readout to most computer operating systems, provide a logging facility, an export facility to Excel, and a flow volume calculator.
All the nets are supplied with a filter. This may be easily unscrewed and the net bag fitted with a draw-string for use with your own bottle or rubber funnel. We can supply alternative cod ends including a tap assembly or clear extension tube if required. The tube can be manufactured to a specific volume if you require a fixed sample size for quantitative sampling. If the net is to be hand thrown we recomend asking for weight tapes to be fitted and if a required for vertical samples weight tapes are essential.
