The rivers flowing waters and semi closed flow control fish ship (referred to as semi closed flow control fish boat), which is mainly composed of two bow type floating box and connected with the frame through a well formed in a semi closed during the semi closed, a well is mainly composed of steel frame, steel plate, steel plate net surrounded by closed in half a well only part with outside water connected, thus reducing the full open cage in the river caused by fish swimming against the current day forced energy consumption, and reduce loss of feeding. Therefore, it can save a lot of feed, reduce the cost of fish farming. And the fish in the river to create a relatively stable habitat environment, improve control effect. Semi enclosed flow controlled fish culture vessel is an ideal device for intensive fish farming in rivers and flowing waters.
【技术实现步骤摘要】
本技术涉及一种江河及流动水域可控养鱼舱内水流速度的新型养鱼装置。目前，国内在利用涨落明显，流速变化大的江河开发网箱养鱼尚未有成熟技术，其主要原因之一就是没有与之适应的养鱼装置，曾有人在江河中置船养鱼，但由于网箱全裸放在江中，江水流动迫使鱼长期处于逆水运动状态，造成很大的鱼体能量消耗，使耗料大幅度增加，甚至出现鱼过于疲劳死亡的现象，投饵流失率也同时增大，严重影响养殖效益。本技术的目的在于提供一种在不同水速的状态下均能满足鱼类正常养殖的江河及流动水域半封闭控流养鱼船。本技术的目的是这样实现的，即这种半封闭控流养鱼船由两个船头型浮箱和通过钢架与之联接在其间的半封闭式养鱼舱组成。半封闭式养鱼舱由钢架、钢板、钢板网组成。本技术的优点在于可以降低养鱼舱内的水流速度，并使养鱼舱在不同流速的河面上或在夏季江水涨落频繁时随时获得适当的水交换量，为鱼类养殖创造了一个相对安稳的环境。既能保持养鱼舱内水质清新，鱼少游动，降低饮料成本，又使鱼长得肥，死亡少，养殖效益高。本技术半封闭控流养鱼船的具体结构由以下附图绘出附图说明图1为本技术半封闭控流养鱼船的实施例之一，该实施例为该船的基本形式，其特征在于养鱼船由两个船头型浮箱和通过钢架与之联接在其间的养鱼舱组成，养鱼舱由钢架、钢板及底部、侧面的钢板网组成。在图中，1 为船头型浮箱，2为侧面交换水网窗，3为养鱼舱，4为栏杆，5为底面交换排污网窗，6为工作棚。图2为本技术半封闭控流养鱼船的实施例之二，该实施例是在第一实施例的基础上增设了侧面交换水网窗盖〔插〕板7，以减缓江河水流过时快养鱼舱内的流速，以增大其适用范围。图3为本技术半封闭控流养鱼...
