Problems solved by technology

Herring is rich in nutrition. In addition to rich protein and fat, herring is also rich in trace elements such as selenium and iodine, so it has anti-aging and anti-cancer effects. Due to the high nutritional value of herring, there will always be shortages in the market. Therefore, the artificial breeding of herring is currently on the rise, but herring farming technology is still relatively traditional, the survival rate of farming is extremely low, and the resistance to stress is poor, resulting in very low breeding benefits

Embodiment Construction

[0020] Advantages The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] A herring and crucian carp pond nest breeding technology, comprising the following aspects:

[0022] (1) Construction pond dredging

[0023] Breeding sites should be selected in rivers, lakes or living ponds that are sheltered from the wind and facing the sun. The water quality is good and there is no industrial pollution. There are special water inlets and drains, the water inlet has a filter, and the outlet has an anti-escape net. The pond is equipped with aerators, water pumps and other facilities. The silt is removed 15 days before the fish species are stocked, and 100 kg of quicklime is used per mu to make slurry Sprinkle the whole pond, so as not to leave any dead corners or surfaces, and completely kill pathogenic bacteria. Afte...

Abstract

The invention discloses a pond polyculture technology for black carps and crucian carps. The pond polyculture technology comprises the following several steps: (1) carrying out pond construction and desilting; (2) carrying out variety matching; (3) carrying out offspring stocking; (4) carrying out feeding management; (5) carrying out water quality management; and (6) carrying out disease control. According to the pond polyculture technology, through carrying out polyculture on the black carps and the crucian carps in culture ponds, the stability of a culture system can be improved, meanwhile, the water quality environment of the ponds can be improved, and the culture benefit of unit area is improved; and an aquatic product drug prepared through compounding natural Chinese herbal medicines has the advantages of nature, multifunctionality, low toxic or side effects and no drug resistance, so that the quality of aquatic products is remarkably improved, and the immunologic function of aquatic animals is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a herring and crucian carp pond nesting technology. Background technique [0002] my country is a big fishery country in the world. Since the reform and opening up, it has always attached great importance to the development of aquaculture industry. For more than ten years, my country's aquatic product output has ranked first in the world. Aquaculture has become a key industry to improve the nutritional structure, increase farmers' income, and promote the development of new rural economy. Our country's aquaculture industry has made great progress, and the breeds are increasingly diversified. Some famous, high-quality, new and precious fish have gradually formed a certain scale of farming, and their industrialization structure is becoming more and more perfect. However, unscientific breeding planning, stocking density, bait feeding, and drug application in the breeding process...
