魁蚶生产采用单船拖曳若干只钢制耙子的单拖作业方式。其捕捞原理是:渔船通过横向固定在船舷两侧的桁杆和纲索拖曳蚶耙前进,蚶耙在海底以一定的频率向前掘动,将魁蚶从海底泥沙中掘起使其进入网袋,以达到捕捞目的。下面对网具结构及其操作作一简介。一、蚶耙和纲索蚶耙呈框架形,其规格随着渔船马力的增大而增 Kuihuan production using a single ship dragging a number of steel rake single trailer operation. The fishing principle is: fishing boats through the lateral fixed on both sides of the ship’s side of the girders and rope tow drag tow advance, rake in the sea at a certain frequency forward digging, the Kui from the seabed sediment to enter into Mesh bags for fishing purposes. The following network structure and operation of a brief introduction. First, 蚶 rake and 索 rake 纲 Rake was frame-shaped, with its specifications as fishing boats increased horsepower
