Spring tide has a great influence on installation of purse seine aquaculture facilities, including serious netting accumulation, entanglement, bottom netting getting away from the base, netting tear, etc. Therefore, it is very important to study the anti-entanglement technology of netting. A small-scale purse seine model was made and 3 different schemes for settlement and lift of netting were designed (i.e., assembled horizontal line, sinking force lines and buoyancy lines) to simulate the netting accumulation in flood and ebb tides. The water level (water level was reduced by 30~60 cm) of obvious netting accumulation was selected for analysis. The results showed that when the water level was reduced by 30 cm, because the method of longitudinal increasing downward of buoyancy and sinking force was used in Scheme C, the netting reached the maximum accumulation height and the minimum accumulation coefficient. When the water level was reduced by 40cm, 50cm or 60cm, the same results were obtained. The study showed that the higher the netting was accumulated, the smaller the accumulation coefficient was, and the netting might accumulate in more layers, resulting in the less possibility of entanglement. The actual application result proves that Scheme C is suitable to be used in spring tide waters.
