Embodiment Construction

[0018] The technical solutions of the present invention will be further specifically described below through examples.

[0019] A kind of sturgeon deep-water cage culture device of present embodiment, as figure 1 Shown, establish the deep-water net cage that length, width and depth are 6*6*15 (meter), the water surface position of net cage 4 is fixed on the floating row 1, and the top of net cage 4 is arranged on the net collecting device 2. At one end, the net collection device 2 is installed on the floating row 1, and the net cage depth measuring device is arranged in the net collection device 2.

[0020] At the depth of 7.5m in the net cage, a middle frame 7 made of stainless steel pipe or nylon rope is set around the net cage 4, and then the middle strand 8 is connected on the middle frame 7, that is, the four sides of the net cage 4 And four corners all connect middle strand 8, and one end of middle strand 8 is connected on the net collection device 2 upwards to the top...

Abstract

The invention relates to the technical field of fishery culture, in particular to a sturgeon deep water net cage culture device. The device aims at solving the problems that a requirement on a growth temperature range in a sturgeon culture process is high, an over-summer survival rate particularly in China south lake and pond culture is low, and a feed coefficient of the existing net cage culture is high. The device comprises a net cage, and is characterized in that a net drawing device is arranged at the top of the net cage; one end of the net drawing device is fixed on a floating mat; a middle strand is arranged on the net cage; a steel plummet ring is arranged at the bottom of the net cage; and a meal table is arranged at the bottom of the net cage. The device can detect temperature automatically, meets requirements on sturgeon growth temperature in different seasons, particularly in a summer; the net cage is convenient and easy to clean and wash; feed is directly fed at the meal table at the bottom of the net cage, which is suitable for the characteristics of demersal fish and lower mouth of a sturgeon; and an entire water tank is good in stability in water.

Description

Technical field [0001] The present invention involves the field of fishery breeding technology, especially a breeding device of catfish deep -water cage. Background technique [0002] Capital fish farming is a highly intensive breeding method that uses high -yielding techniques to use the tightly stimuli technology to a large surface with superior environmental conditions. It can make full use of water bodies and bait creatures. It is easyThe advantages of easy and easy to catch, so it is widely used.The existing deep -water cages have different structures and have different characteristics for different waters and different fish species.For example, a large or extra -large breeding, tourism deep -water cage, a large or large breeding, tourism deep -water cage, a patent public account, a rope, a force, a fixed -gravity fixed device, a safe fixed rod and a gangster of the meter.Composition can withstand the impact of wind, waves, and flow of a certain intensity.Another example is ...
