• Field experiments were conducted to know the mechanical characters of the shrimp beam trawl used in Taiwan. The experiments were carried out on a flat sand bottom of shallow sea so that it is convenient for skin divers to measure the height of net mouth di-rectly. The height of net mouth and the tension in warp were measured with changes in the weight of the bridle stone and in the towing speed. It was found that the height of net mouth increased rapidly with the towing speed, contrary to other trawl gears. In con-nection with this, the tension in warp increased in proportion to the 2.5 power to the towing speed. Any effect of the weight of the bridle stone on the height of the net mouth was not seen within this experimental range.
