1. An apparatus for subsampling water macroinvertebrate comprising:
- a) an external tray comprising;
i) a reinforcement edge adapted to assist in supporting a weight of the apparatus and keeping a shape of the apparatus;
ii) a water outlet system;
iii) an S-shaped leg support system arranged in parallel to a water flow line so as to jointly avoid a loss of tray shape and a backflow phenomenon; and
