摘要： An automatically closing drop fishing net is provided for commercial fishing operations. The drop net assembly includes an upper float ring, a lower weight ring, and a net formed in a generally tubular configuration. The upper end of the net is attached to the float ring and the lower end of the net is attached to the weight ring. The drop net assembly has several torque lines that extend from locations on the float ring on the outside of the net to locations on the weight ring that are initially angularly offset at least one hundred eighty degrees relative to their points of attachment to the float ring. The torque lines are shorter than the vertical length that the net would assume in a stretched condition with the float ring buoyed upon the surface of a body of sea water and with the weight ring suspended therebeneath and held only by the structure of the net. As gravity pulls the weight ring downwardly from the float ring in the water, tension is exerted on the torque lines. This tension causes the weight ring to rotate relative to the float ring above it. The twisting of the weight ring also twists the net, thereby closing the lower portion of the net and changing its shape from a generally cylindrical configuration to a configuration of an upper inverted cone and a lower, upright cone. Fish are entrapped within the upper, inverted conical portion of the drop net assembly once it has been deployed.
摘要翻译：为商业捕鱼作业提供自动关闭的下垂渔网。下沉组件包括上浮动环，下重圈和形成为大致管状构造的网。网的上端连接到浮环，网的下端连接到重量环。滴网组件具有几个扭矩线，其从网的外部的浮环上的位置延伸到重量环上的位置，该位置最初相对于其与浮环的连接点成角度地偏移至少一百八十度。扭矩线比垂直长度短，网在拉伸状态下呈现的垂直长度，其中浮环悬挂在海体表面并且重量环悬挂在其下并且仅由网的结构保持。当重力从水中的浮环向下拉动重量环时，张力被施加在扭矩线上。这种张力使得重量环相对于其上方的浮环旋转。重量环的扭转也扭转网，从而关闭网的下部，并将其形状从大致圆柱形构型改变成上倒置锥体和下直立锥体的构型。一旦它已经展开，鱼被捕获在滴网组件的上部，倒置的锥形部分内。

摘要： A non-collapsible fish net apparatus (31) with capturing method, comprising an endless net (33) mounted on spaced rigid hoops (37, 38) preventing collapse, a skirt (39) below the lower hoop (38) foldable on itself, apparatus support lines (45) mounted to the upper hoop (37), control lines (51) folding and unfolding the skirt (39), a draw line (62) about the skirt (39), a closure weight (57) attached to the draw line (62), and a line (58) for dropping the weight (57) farther down to close off the skirt (39). Buoys (55) on the control lines (51) provide a signal for actuating the weight (57). Corks (44) on the upper hoop (37) float apparatus (31). A wave netting (70) at the upper hoop (37) prevents fish escape in a wave cascade over apparatus (31). A quick-disconnect assembly (65) on the draw line (62) distal to the closure weight (57) opens the skirt (39) in event of apparatus overload. Apparatus (31) encompasses fish in water after which the draw line (62) is tightened by release of the weight (57), thus, capturing them.
