Problems solved by technology

Illumination, salinity, temperature, pH, etc. are the main environmental factors that affect the growth of algae. At present, open cultivation in cement pools is mainly used in production. This method has relatively simple equipment, but the contact area between the algae liquid and the air is large

Abstract

The culture equipment of bait microalgae mainly is formed from microalgae culture bag, light source, air pipe, guide shell, oxygen-enriching pump and tourmaline, in which the microalgae culture bag is mounted on the base seat, and is positioned in the cylindrical steel wire ring, the bottom portion of the microalgae culture bag is equipped with algae liquor discharge outlet which is communicated with bait tank, and the top of the microalgae culture bag is equipped with water inlet pipe communicated with the cultured algae seed, prepared nutrient liquor and disinfected sea water, its interior is equipped with a guide shell, and the air pipe is positioned in the guide shell. Said equipment can implement all-weather high-density culture of bait microalgae, and its method is simple.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a cultivation device for bait microalgae, which is used for cultivating main aquatic organism bait—bait microalgae and the like required in aquaculture production. Background technique [0002] The biological bait after manual screening and artificial cultivation is a kind of high-quality bait for aquatic animal breeding, especially seed production, and plays an irreplaceable role in production. Illumination, salinity, temperature, pH, etc. are the main environmental factors that affect the growth of algae. At present, open cultivation in cement pools is mainly used in production. This method has relatively simple equipment, but the contact area between the algae liquid and the air is large, and it is easy to be affected by harmful organisms. Pollution, and is greatly affected by human, season, weather and other factors, resulting in low production capacity, poor stability, weak anti-ris...
