Suspending portable mesh cage for fish farming in river with ecologically dynamic water

Abstract

The invention discloses a suspending portable mesh cage for fish farming in a river with ecologically dynamic water. The mesh cage comprises at least two support rings which are arranged in sequence from front to back; a folding rack is arranged between each two adjacent support rings; the two ends of each folding rack are hinged with the two support rings respectively; each folding rack is formed by hinging two support bars with each other from front to back; the support bars are hinged with the support rings; the support rings and the folding racks form a foldable mesh cage framework which is wrapped by mesh pieces; and floating balls are arranged on the folding racks or on the mesh pieces near the folding racks. On one hand, the mesh cage is foldable, can be folded to reduce the size during transportation and carrying, and therefore has the advantages of small size and light weight. On the other hand, the mesh cage can automatically spread under the actions of water flows and floating balls in water, and float in a superjacent water area, thereby making common carps always live in an environment with a higher flow rate and urging the common carps to keep moving. Therefore, the fish has high activity, strong muscle and delicate flesh.

Description

technical field [0001] The invention relates to a suspended portable net cage for raising fish in an ecological dynamic river. Background technique [0002] Yellow River carp is famous all over the country for its bright colors and delicate meat. Its above-mentioned excellent quality mainly depends on the characteristics of the Yellow River's high sediment content, low sunlight, and rapid water flow. But, just because the Yellow River has the above-mentioned characteristics, it is necessary to adjust water and sand on a regular basis, so that the culture cages need to be frequently moved to adjust their positions. And existing net cage self is heavier, and can't be folded, and volume is bigger, therefore, inconvenient to carry, carry, do not adapt to the requirement of regular water and sand regulation of the Yellow River, thereby, can't reach the condition of cultivating Yellow River carp. Contents of the invention [0003] The object of the present invention is to prov...

AI Technical Summary

Problems solved by technology

However, because the Yellow River has the above-mentioned characteristics, it is necessary to adjust water and sand on a regular basis, so that the breeding cages need to be frequently moved to adjust their positions.

However, the existing net cage itself is heavy, and cannot be folded, and has a large volume, so it is inconvenient to carry and carry, and is not suitable for the regular water and sand regulation of the Yellow River, thereby failing to reach the conditions for cultivating Yellow River carp
