Water quality modifier for shrimp and crab aquaculture and preparation method of water quality modifier

Abstract

The invention discloses a water quality modifier for shrimp and crab aquaculture and a preparation method of the water quality modifier. The water quality modifier is prepared from the following raw materials in parts by weight: 20 to 30 parts of modified bentonite, 10 to 15 parts of amino acid, 2 to 10 parts of chitosan, 0.5 to 1.5 parts of bacillus, 2.5 to 5.5 parts of nitrobacteria, 1.2 to 2.4 parts of acetylcholin esterase, 3 to 10 parts of nano clay, 2 to 15 parts of corn meal, 2 to 10 parts of active carbon particles, 2 to 5 parts of honey, 2.5 to 6.5 parts of a trace element mixture and 5 to 10 parts of a Chinese herbal medicine extract. According to the water quality modifier for the shrimp and crab aquaculture and the preparation method of the water quality modifier, water balance adjustment for aquaculture can be realized, and aging of the water quality of aquaculture water can be prevented.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a water quality improver for shrimp and crab cultivation and a preparation method thereof. Background technique [0002] With the rapid development of aquaculture in my country, the proportion of aquaculture in the aquaculture industry is increasing continuously. Due to the continuous expansion of market demand, the breeding density of aquaculture farmers is also increasing. The increase in breeding density has accelerated the cycle of water quality aging and water quality deterioration. Water quality indicators such as ammonia nitrogen, nitrite, hydrogen sulfide, and dissolved oxygen in the water body are not easy to control. In addition, weather changes such as rain, stormy weather, and changes in water temperature and salinity will cause unbalanced osmotic pressure and stress in farmed animals. Excitement and decreased immunity can easily lead to explosive bacterial inf...

Problems solved by technology

Increased breeding density speeds up the cycle of water quality aging and water quality deterioration

Water quality indicators such as ammonia nitrogen, nitrite, hydrogen sulfide, and dissolved oxygen in the water body are not easy to control. In addition, weather changes such as rain, stormy weather, and changes in water temperature and salinity will cause unbalanced osmotic pressure and stress in farmed animals. Excitement, decreased immunity, easy to cause explosive bacterial infection and death, resulting in breeding failure

In the past, aquaculture farmers used a large number of antibiotics for prevention and control, and the abuse of antibiotics accelerated the deterioration of water quality, causing secondary stress on farmed animals, which brought greater difficulties to disease control, easily caused explosive death of farmed animals and affected the quality of farmed animals

Exports are affected, causing indirect harm to the human body
