This study used model experimental nets tested in a circulating water tank. Three kinds of trawls were tested, i.e. the Mexican semi ballon double rigged shrimp trawl designed by Nichimo (hereafter called net A), the traditional two seam single rigged Malaysian shrimp trawl (net B) and the four seam trawl modified from the above Malaysian trawl (net C). The head rope length of net A is about half that of net B and net C. Primary objectives are to determine physical characteristics, working performance and to estimate the main engine output necessary to pull these nets.\nTo provide a double rigged shrimp trawl in the Malaysian shrimp fisheries, results\nof experiments are summarised as follows:", "subitem_description_type": "Other"}, {"subitem_description": "1) At 2 knots, which is a normal towing speed of a Malaysian shrimp trawler,\nnet mouth height of net A is 1.2 meter, net B is 2 meter and net C is 1.8 meter.
