Self-circulation peneid culture system

Abstract

The invention belongs to the technical field of aquaculture equipment, and relates to a self-circulation peneid culture system. Wool ball bags are installed on horizontal bars of the pond wall of a culture pond. The wool balls in the wool ball bags are used as the carriers for the microorganism growth. When the culture system is established, nitrifying bacteria is added to the wool balls to make the nitrifying bacteria reproduce on the wool balls and form dominant bacteria in a short time, and therefore toxic substances such as ammonia and nitrite are fast removed from the culture water body to make the culture pond can be used for culturing peneid and automatically purifying the water to form a stable system without the need of adding microorganism solution to in a qualitative and quantitative mode to the culture system. The self-circulation peneid culture system has the advantages of being simple in structure, low in production cost, and easy for maintenance. The system overcomes the shortcoming that in the traditional culture system, it is necessary to qualitatively and quantitatively adding microorganism bacteria solution. After the use of the culture system, water change frequency of the culture system is reduced, the culture efficiency is enhanced, the application is environmentally friendly, and the market prospect is wide.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of aquaculture equipment, and relates to a prawn farming system, in particular to a self-circulating prawn farming system. The hair ball in the hair ball bag is used as a carrier for microbial growth, and nitrifying bacteria are added to make nitrification Bacteria proliferate on the hair balls and form a dominant bacterial group in a short period of time, thereby quickly removing toxic substances such as ammonia and nitrite in the aquaculture water, enabling the aquaculture pond to breed prawns and automatically purify the water quality. [0003] Background technique: [0004] my country is a big aquaculture country, and its annual output ranks first in the world. For a long time, pond culture has been the main culture mode of prawns in my country, and most of them are extensive. There are two defects in this culture method. Large, according to the available statistics, it takes 20 cubic meters of cle...

Problems solved by technology

However, because ammonia oxidizing bacteria and nitrite oxidizing bacteria are chemoautotrophic bacteria, they use carbon dioxide as a carbon source and oxidized inorganic nitrogen as an energy source, their growth and reproduction speed is slow, and they are sensitive to changes in environmental factors. In view of the above problems, a self-circulating shrimp culture system is designed, which fully considers that the water depth of the shrimp culture pond is mostly about 1 meter, the shrimp likes to live in the middle and lower layers of the water body, and the nitrifying bacteria attach to grow and utilize Inorganic substances are used as carbon sources, and a self-circulating shrimp culture system is established. The system makes full use of the space of the culture pond, and places hair ball bags above the water body of the culture pond, and uses the hair balls in the hair ball bags as the carrier of nitrifying bacteria; The Ammonia and Nitrite Removal Ability of the System Enhanced by Adding Nitrifying Bacteria Preparations in the Hair Ball Bag
