چکیده انگلیسی
⺠A new multiple layer sampling trawl was developed to sample pelagic juvenile fish quantitatively. ⺠The trawl system (5 layers, 4 m2 mouth area, 490 kg in air) can be towed at the towing speed of 2 m sâ1. ⺠Net opening/closing is controlled by an autonomous control system with respect to depth, time or flow. ⺠Control system also records the net depth, temperature and flow rate during net towing.
