Description

Flowing water type artificial seed cultivation device for squid

technical field

The invention relates to a continuous factory aquatic product seed cultivation system, in particular to a flowing water artificial seed cultivation device for squid.

Background technique

In recent years, my country's aquaculture industry has developed rapidly, and the traditional extensive farming methods can no longer meet the needs of aquaculture development. It is an inevitable trend to replace the traditional extensive aquaculture method with the advantages of water saving, environmental protection, controllable water quality, and production not affected by climatic conditions by adopting the industrialized recirculating aquaculture system. At present, in the production of aquatic seedlings, the method of raising seedlings in large water bodies and concentrated water is mainly used. This method mainly uses artificial synthetic bait to feed seedling larvae, which is easy to pollute the water quality and cause the seedlings to suffer from diseases or immunity decline due to stress. In addition, in order to reduce the disease organisms in the polluted water body and improve the success rate of seedling cultivation, antibiotics are often used in the seedling raising process, which also seriously affects the quality of the seedlings and even the quality of the final cultured products. Such as China's invention patent application "A method for raising seedlings of Litopenaeus vannamei in small water body with clear water", patent application number 200610122425.5, which discloses a method for raising seedlings of Litopenaeus vannamei in small water body with clear water for aquaculture. The method includes Three key control processes are water quality treatment control, bait feeding control, and shrimp fry quality control. In the process of water quality treatment, after the water is sterilized by sand filtration, ozone and ultraviolet light, it must also be filtered through filter membranes with pore sizes of 10, 1.0, and 0.5 pm. Water quality; bait feeding control mainly adopts Sclerostena, Chaetoceros and Artemia as bait, and artificially synthesized bait is properly fed after the second stage of psyllium; Seedlings can only emerge after passing the tolerance test or the starvation tolerance test. However, this method has certain ecological pressure and cannot be directly transplanted into the production process of squid seedlings.
