Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the examples, but the embodiments of the present invention are not limited thereto.

[0037] The specific implementation location is a nursery farm in Shandong Province, and the implementation time is 8 months. The water quality conditions in the sea area of ​​the test site meet the requirements of the National Standard Fishery Water Quality Standard of the People's Republic of China (GB11607-89) and the Ministry of Agriculture's "Water Quality of Pollution-Free Food and Marine Aquaculture" (NY5052-2001). The breeding ponds for turbot are built in greenhouses, and each pond has an area of ​​40m 2 , the water depth is 1.2 meters, and the bottom of the pool is concave, which is conducive to operations such as drainage and sewage suction, and a flat bottom can also be used. Cover the pool with a shading cloth with a shading degree of 95% to avoid excessive light. The light intensity is ge...

Abstract

The invention discloses an energy-saving and emission-reducing culture method of turbot, comprising the following steps: selection of a culture water source, treatment of water in a pond; treatment of feedstuffs, control of water changing period, and control of culturing environment by adopting a bioecology method according to the ecological principle of culturing water bodies, growing environment requirements of sea animals, mutual relation among organisms and nuisanceless culturing standards. The key technology is as follows: mixed bacteria liquid of bdellovibrio bacteriovorus swimming bodies and leech plasmids is added in a water body, simultaneously the feedstuffs also are soaked by the mixed bacteria liquid of the bdellovibro swimming bodies and the leech plasmids, and during the culture, water in a pond is changed every 40 days. The method disclosed by the invention is a biological culturing method, is green, safe and no-pollution, also the effect is obvious, the water quality can be improved, the growth of the turbot is enhanced, the immunity is improved, the survival rate is increased, and the development prospect is extremely good. Therefore, the energy-saving and emission-reducing culture method has very important significance for improving the economic benefit and eating safety and guaranteeing the human health.

Description

technical field [0001] The invention belongs to the technical field of marine fish culture, and in particular relates to a turbot breeding method that improves the immunity of turbot, promotes the rapid growth of turbot, improves water quality, saves water and energy, saves manpower and material resources, and is green and low-carbon. Background technique [0002] Turbot (Scophthalmus maximus) is a rare and valuable flounder native to Europe. It has a gentle temperament, a beautiful body, rich white and tender muscles, and rich colloid between the fins, which is similar to the skirt of a soft-shelled turtle and the flavor of a sea cucumber. It has high nutritional value and is an ideal health care and beauty food. It is deeply loved by consumers. Turbot, as a well-known breed in the world, has been highly valued by the international breeding community, and its breeding range is constantly expanding. [0003] Since my country broke through the large-scale productive breeding...
