Embodiment 1

[0042] 1. Functional analysis and design principles of crab recirculating aquaculture system

[0043] Recirculating aquaculture systems utilize a range of water treatment techniques to remove solids, ammonia and nitrite nitrogen, degassing and oxygenation. The principles of these water treatment technologies are also the basic basis for the establishment, commissioning and operation of production systems.

[0044] (1) Removal of solid waste

[0045] Sources of solid waste in the aquaculture industry include manure and other excreta of farmed animals and leftover feed. The main ingredients of feed generally include protein, carbohydrates, fat, ash and water. The metabolites of farmed animals are excreted in the system in the form of organic waste, and are decomposed by bacteria together with excess feed, consuming oxygen and producing ammonia. To minimize their impact on water quality, solid waste must be removed from the system as quickly as possible. (2) Control and remov...

Abstract

The invention belongs to the technical field of crab breeding, and discloses a method for improving crab recirculating aquaculture efficiency by controlling water quality and water temperature. A crabrecirculating aquaculture system is composed of a water treatment system and a breeding system; the water treatment system is composed of a microfiltration machine, a protein separator, an ozonizer,a biological filter, an oxygen generator, an oxygen dissolving cone and a constant-temperature mechanism; the breeding system is a box crab recirculating aquaculture system. The crab factorization recirculating aquaculture system can provide an independent a breeding box for each crab, each breeding box is provided with an independent water feeding system, an independent water discharge system andan independent water feeding oxygenation system, and feces and residual baits can be subjected to semi-automatic discharge, so that high-quality water and a comfortable spatial environment are maintained to be completely consistent in all the breeding boxes; meanwhile, various efficient water treatment systems are arranged to conduct control adjustment on the water quality and water temperature,and an efficient new indoor stereoscopic crab recirculating aquaculture mode is achieved.

Description

technical field [0001] The invention belongs to the technical field of crab cultivation, and in particular relates to a method for improving the efficiency of crab recirculating aquaculture by controlling water quality and temperature. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] With the development of society, the shortage of water resources threatens the production and life of many regions and cities. Traditional aquaculture production methods are restricted and restricted by various factors, and various disadvantages are constantly emerging, including pollution of water sources, waste of water resources, etc., exposing the limitations of unsustainable production. The recirculating aquaculture mode is the most industrialized production mode among the many modes of aquaculture. Compared with the flow-through aquaculture mode, it can save more than 90% of water and 99% of land, and can also achie...
