Abstract
The invention belongs to the field of net cage culture, and particularly relates to a feed recovery culture net cage and a recovery method thereof. The invention can recover the residual feed in the net cage to avoid influencing the water quality.
Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a feed recovery aquaculture net cage and a recovery method thereof.
Background
The net cage culture originated in southeast Asia countries such as Cambodia at the end of 19 th century and then was transmitted to all over the world. As the net cage culture has the characteristics of low investment, high yield, mobility, quick response and the like, the net cage culture develops vigorously in lakes, reservoirs and even oceans all over the country in short decades, and some net cages serving as culture main bodies are made into hexahedral frames which can be made of metal, wood or moso bamboos. After the integral framework is installed, the wind and wave resistance in water is strong, and if the box is lack of oxygen, the integral movement of the net cage is very convenient. The clothes are also very convenient to be dried by the sun to eliminate attachments, but the clothes are troublesome to carry. The net cage frame is also only provided with a plane square frame, and is provided with a floater and a sinker to suspend the net in water.
The cage culture mainly accelerates the growth of cultured fishes by artificially feeding baits, and inevitable parts of the fed baits are scattered in a water body, and certain influence can be generated on physical and chemical factors of the water body, and the cage culture mainly comprises: dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Nitrogen (TN), ternary nitrogen, Total Phosphorus (TP), transparency, and the like. The residual feed is a decisive factor of water quality, suspended matters in water are increased in a cage culture water body, the transparency of the water body is reduced, and oxygen generated by photosynthesis of phytoplankton is reduced, which is extremely unfavorable for fish respiration and decomposition of organic nutrient substances in the cage culture water body, the chemical oxygen demand in water is improved due to the increase of the content of organic substances, part of organic substances in the water body are incompletely oxidized, toxic gases such as H2S and NH3 are generated, the health of cultured fishes is harmed, a large amount of death of the cultured fishes can be caused in a serious case, but no better solution is provided for recovering the residual feed in the cage culture water body at present.
Therefore, a feed recovery aquaculture net cage and a recovery method thereof are provided to solve the problems.
