介绍了一种新型网箱的设计、建造和使用情况。矩形结构基于一个刚性的聚丙烯框架，可以很容易地通过预制件套件进行组装。保持架的浮力可以通过封闭在刚性框架内的氯丁橡胶钢瓶的充气和放气来调节。可以选择水下或漂浮操作模式。在漂浮模式下，可使用氯丁橡胶气缸实现保持架绕长轴旋转45°或90°。通过这种方式，网板可以暴露在表面上，以清除生物污垢，捕捞鱼类，并控制圈养种群对治疗剂的暴露。
The design, construction and operation of a new type of fish cage is described. The rectangular structure is based on a rigid polypropylene frame that can be readily assembled from a kit of prefabricated parts. Buoyancy of the cage can be regulated by inflation and deflation of neoprene cylinders enclosed within the rigid frame. A submerged or floating mode of operation can be selected. In the floating mode the neoprene cylinders can be used to effect the rotation of cage about the long axis in steps of 45 or 90°. In this way, mesh panels can be exposed on the surface for removal of biofouling, for harvesting of fish and for controlled exposure of the captive population to therapeutic agents.
