RMT Net (Rectangle Mid-Water Trawl)

Scientific Research
Product type:
Plankton Net
Fresh Water Sampling, Salt Water Sampling, Vertical Water Sampling, Micro-Plastic Sampling, Horizontal Water Sampling
Lead time:
30 to 60 days
The main purpose of the RMT Net is to perform a double sampling of zooplankton and nekton on two superimposed strata
  • The RMT (Rectangle Mid-Water) net is a sophisticated sampler used to study the vertical distribution of plankton and nekton.
  • The large size of the gear and its features improve the catch efficiency of several species.
  • There are several models, with one or two nets of different dimensions.
  • The opening is usually vertically asymmetrical (the top being more advanced than the bottom).
3 standard models exist, including:
  1. RMT1: top net with an opening of 1m² with a
    size of 335 microns used to catch mesozooplankton 
  2. RMT8: top net with an opening of 8m² and a mesh size of 5 mm for the capture of macroplankton 
  3. RMT25: top net with an opening of 25m² and a mesh size of 5 mm, used to catch mesopelagic fish

Manufacture details: The net is made of ultra-strong and extremely precise Nitex filtration mesh. We have over 60 options of filtration mesh sizes varying from 1 to 5000 microns
The net mouth and tail are reinforced with non-treated Cordura
1000 Deniers on which
are added (net mouth) and a clamping device (net tail) to hold onto the
. Every seam is reinforced with 3/4in webbing to guarantee an ultra strong net
Ideal for capturing phytoplankton (smaller than 80 microns), zooplankton (60 to 600 microns) and other micro-organisms (500 to 5000 microns)
It is possible to add a chocking band on the net which is formed by passing a rope through small
stainless steel
rings sewn within the net, thus allowing the user to close and open the net during operation
For nets with a diameter larger than 100cm, extra reinforced webbing is added on the lenght of the net to maximise it's structural integrity
Idéal pour la capture d'autres organismes (500 à 5000 microns) ou en filet de
