Fish and shrimp farming box

Abstract

The invention discloses a fish and shrimp farming box which comprises a net cage, an inflatable bladder and an anchor bearing, wherein the inflatable bladder is arranged on the side wall of the net cage; the anchor bearing is fixed at the water bottom; the net cage comprises a top screen, a left side plate, a right side plate, a front side plate, a rear side plate and a bottom solid plate; multiple side through holes are formed in the left side plate, the right side plate, the front side plate and the rear side plate; at least one stay rope is arranged on the anchor bearing; one end of the stay rope is connected with the anchor bearing, and the other end of the stay rope is connected with the net cage; the net cage further comprises three vertical support rods arranged at the bottom of thebottom solid plate; and the axis of any one vertical support rod is positioned outside a plane passing through the axes of the another two vertical support rods. The fish and shrimp farming box disclosed by the invention has the beneficial effects that the structure is simple, fishes, shrimps and other aquatic products needing to be farmed can be effectively contained, rapid height adjustment canbe performed according to the requirements, and the box can be conveniently arranged nearby the water surface; and when the net cage sinks to the bottom, the net cage can be prevented from being buried by sludge, and lots of sludge at the water bottom can also be avoided from entering the net cage.

Description

technical field [0001] The invention belongs to the technical field of aquatic products and culture, and in particular relates to a fish and shrimp culture box. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. Generally, it includes the whole process of growing aquatic products from seedlings under artificial breeding management, and in a broad sense, it can also include the proliferation of aquatic resources. In aquaculture, fish and shrimp farming occupies a large proportion. At present, for fish and shrimp farming, there are fence culture, cage culture, pond culture and other means. Among them, net cage culture is to breed fish and shrimps in net cages, and the net cages are placed in waters. However, the installation of cages in water areas is relatively troublesome. The water depth range suitable for a large number of fish is close to the water surface. However...

Problems solved by technology

However, the installation of cages in water areas is relatively troublesome. The water depth range suitable for a large number of fish is close to the water surface. However, setting the cages near the water surface requires pre-installed piles, which is costly and inconvenient to maintain. Moreover, The convenience of packing fish into and out of the box is also relatively lacking
