Industrialized staircase-overflow-type fish/Apostichopus japonicus compound culture device and method

Abstract

The invention discloses an industrialized staircase-overflow-type fish / Apostichopus japonicus compound culture device which comprises a flounder culture tank and an Apostichopus japonicus culture tank, wherein the top of the flounder culture tank is provided with a water inlet pipe, the bottom of the flounder culture tank is provided with a first drainage pipe, a drainage port of the first drainage pipe communicates with an overflow water inlet pipeline, a water collecting groove communicates between the drainage port of the first drainage pipe and the overflow water inlet pipeline, the overflow water inlet pipeline communicates with the Apostichopus japonicus culture tank, and the bottom of the Apostichopus japonicus culture tank is provided with a second drainage pipe. As for the flounder culture, an intermittent running water change mode is adopted every day, and the water change quantity is 2-3 ranges; before the running water change, the water level of the Apostichopus japonicus culture tank is lowered or the tank is drained; and the flounders spilling over the drainage port are collected into the water inlet pipe through the water collecting groove, and the flounder culture water can enter the Apostichopus japonicus culture tank along the water inlet pipe to supplement the Apostichopus japonicus culture water level, thereby implementing the reutilization of culture water from the flounder culture tank to the Apostichopus japonicus culture tank.

Description

technical field [0001] The invention relates to the technical field of seawater industrial culture, in particular to an industrial gradient overflow type fish and ginseng compound culture device and method. Background technique [0002] Seawater industrial aquaculture is a kind of industrialized high-density seawater aquaculture mode that uses indoor seawater pools as aquaculture facilities and artificially regulates water temperature, water quality, dissolved oxygen, light, feed and other conditions to supervise and control the whole process of aquaculture. Breeding species are in the best environment to achieve the fastest growth rate. After years of development, seawater industrial aquaculture has achieved some success in increasing the output of aquatic products, saving energy and reducing emissions, and protecting the ecological environment. It has become an important development mode of the world's mariculture industry. Different models, facilities and technologies fo...

AI Technical Summary

Problems solved by technology

At present, more than 90% of the factory farming of flounder and flounder adopts the open flow mode, which has disadvantages in site selection of breeding sites, energy conservation and emission reduction, and does not meet the increasing development requirements of energy conservation and emission reduction; at the same time, single sea cucumber and flounder flounder At present, there are problems such as high cost of breeding, increasingly saturated space, and high market risk in all kinds of farming.
