Problems solved by technology
[0002] To raise fish, raise water first, that is, fertilize water first, and cultivate aquatic plants, algae, plankton, etc., so as to meet the growth needs of fish. Now, rivers usually use block culture or cage culture. Due to the rapid water exchange caused by water flow, it cannot be cultivated. Fertilizer water and feed are also wasted due to the water flow. Fish like to flow countercurrently in the water flow, which also causes nutrient consumption. Therefore, the current river aquaculture production is not high
In addition, because it is not a closed culture, the fish are directly affected by the temperature and cleanliness of the upstream water flow, and some even die as a whole because of the toxic and harmful sewage.

Embodiment
[0034] Embodiment: With reference to accompanying drawing, a kind of river closed culture facility, comprises water-blocking film 2 and diversion pipe 3, is separately provided with water-blocking film 2 longitudinally at the upstream and downstream of the river at a predetermined distance to block flowing water, described diversion The pipe 3 is arranged horizontally and its two ends are respectively connected to two upstream and downstream water-blocking films 2 . The size of the breeding area is set according to the needs, and the diameter of the diversion pipe is set according to the local maximum flow.
[0035] In a further preferred solution, the water-blocking membrane 2 is made of a rectangular soft impermeable material, which is arranged longitudinally in the water body of the river, and its two ends are arranged in the soil of the river bank 1 on both sides of the river, and its upper edge is higher than The water surface is at a certain height, and its lower side is...

Abstract
The invention relates to a river closed aquaculture facility and making, constructing and aquaculture methods thereof. The aquaculture facility includes water-blocking membranes and a flow-guiding pipe, wherein the water-blocking membranes are longitudinally and separately arranged on the upstream part and downstream part of a river at preset distance to block flowing water, the flow-guiding pipe is transversely arranged, the two ends of the flow-guiding pipe are communicated with the two water-blocking membranes on the upstream part and the downstream part of the river respectively, water on the upstream part flows into the downstream part, and a relatively closed aquaculture region is formed between the two water-blocking membranes. In this way, culture of rich water is convenient, conditions are created for high yield during aquaculture, meanwhile, the water from the upstream part will not influence the water quality inside the culture region, and the water is changed according to needs during aquaculture.
Description
technical field [0001] The invention relates to the technique of intercepting fish in flowing rivers, in particular to a closed river breeding facility and its manufacturing, construction and breeding methods. Background technique [0002] To raise fish, raise water first, that is, fertilize water first, and cultivate aquatic plants, algae, plankton, etc., so as to meet the growth needs of fish. Now, rivers usually use block culture or cage culture. Due to the rapid water exchange caused by water flow, it cannot be cultivated. Fertilizer water and feed are also wasted due to the water flow. Fish like to flow upstream in the water flow, which also causes nutrient consumption. Therefore, the current river aquaculture output is not high. In addition, because it is not a closed culture, the fish are directly affected by the temperature and cleanliness of the upstream water flow, and some even die as a whole because of the toxic and harmful sewage.
