Cyprinuse carpio circulating water culture system with water-saving and ornamental functions

Abstract

The invention belongs to the field of industrialized aquiculture, and in particular relates to a Cyprinuse carpio circulating water culture system with water-saving and ornamental functions. The system comprises a culture pond, a middle-upper layer water treatment subsystem and a middle-bottom layer water treatment subsystem, wherein the culture pond is provided with two water outlets; one water outlet is arranged on the part, adjacent to the middle-upper layer water, of the side surface of the culture pond, and the effluent water from the water outlet is subjected to sedimentation, filtration and sterilization in the middle-upper layer water treatment subsystem and then returned to the culture pond; and the other water outlet is arranged in the center of the bottom of the culture pond, and the middle-bottom layer waste culture water from the water outlet is guided to the middle-bottom layer water treatment subsystem through an underground connector and then returned to the culture pond after filtration and purification, as a result, a circulation cycle is achieved. Meanwhile, the heights of the vertical drain pipes in the water treatment subsystems are adjusted to control the quantity of water discharged from the drain pipes, therefore, the Cyprinuse carpio circulating water culture system has a reasonable technical process, is convenient in operation and management, has a low cost, and can meet the needs for culture and ornament of Cyprinuse carpio.

Description

Technical field [0001] The invention belongs to the field of aquaculture, and specifically relates to a koi recirculating aquaculture system with both water saving and ornamental functions. Background technique [0002] Koi (Cyprinus carpio L.) belongs to Cypriniformes, Cyprinidae, and Cyprinus. It is called Nishikigoi in Japan. It is called Nishikigoi because of its strong body, gorgeous color, gorgeous markings, and chic. Swimming style and docile habits are world-renowned, and they are called "aquatic gems" and "arts that can swim." [0003] Koi is a large-scale precious ornamental fish that is artificially bred and oriented bred from mutant carp strains. The body color and pattern are varied, and the contrast of body color and color spots is also an important embodiment of ornamental value. In daily production, the fish can be cultured in outdoor ponds and cement ponds. Because the cultivation area of ​​cement ponds is small, it is easy to watch and sell, and the close-up view...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the technical problems such as weak water purification ability, high operating cost and low water treatment frequency of the existing circulating aquaculture system, and to provide a method suitable for koi carp by combining physics and engineering. A recirculating aquaculture system with both water-saving and ornamental functions for large-scale high-end ornamental fish to meet their breeding and appreciation needs
