Technical Analysis of Adjustments to Beam Trawl Fishing Gear and Methods
At present, beam trawl shrimp trawling has become one of the important operating methods of marine fishing in coastal fishing areas, and its output value as a proportion of the total marine fishery output value has risen year after year. Since this operating method belongs to single-boat bottom beam trawl operation, its gear design, rigging, operational adjustment, and fishing ground selection and other stages are all fairly highly technical, so even a slight oversight can affect shrimp trawling production. In particular, the adjustment techniques in beam trawl operation are the key to fishing production technology. For example, in production practice everyone often encounters this phenomenon: the same
