Composite stichopus japonicus growth promotion micro-ecological preparation and feeding method thereof

Abstract

The invention discloses a composite stichopus japonicus growth promotion micro-ecological preparation. The micro-ecological preparation is characterized by comprising photosynthetic bacteria, bacillus subtilis, lactic acid bacteria and rhodotorula benthica, wherein the concentration ratio of the photosynthetic bacteria to the bacillus subtilis to the lactic acid bacteria to the rhodotorula benthica is (3-5.5):(3.5-5):(0.5-1.5):(1-1.5); the final concentration of both the photosynthetic bacteria and the bacillus subtilis is (0.5-1.5)*10<4>cfu/ml; and the final concentration of both the lactic acid bacteria and the rhodotorula benthica is (2-4)*10<3>cfu/ml. When in use, 7-10 days are used as one cycle, the four micro-ecological preparations with the above concentration ratio are diluted by 10-15 times by water, are mixed uniformly and then are uniformly spilled into culture water respectively, in the second day of the primary feeding operation, the preparations are spilled with the amount that is a half of the feeding amount of the first day, and the proper water temperature for feeding is 15DEG C to 28 DEG C. The micro-ecological preparation for the healthy culture of stichopus japonicus is easy to get, significant in effect and relatively low in cost.

Description

technical field [0001] The invention relates to an ecological preparation, in particular to a combined sea cucumber growth-promoting microecological preparation and a delivery method of the preparation. Background technique [0002] With the continuous expansion of the scale of aquaculture in our country, the phenomena of overloaded farming, excessive discharge and excessive antibiotics have become increasingly prominent. Maintaining a healthy ecological environment and implementing green and healthy farming has become a key issue related to the sustainable development of the aquaculture industry. The emergence of microecological preparations provides the possibility for aquaculture to take a green and healthy farming model. Microecological preparations are live bacterial preparations containing a large number of beneficial bacteria that are made from microbial cells screened from the natural environment and cultured and propagated. Micro-ecological preparations do not con...
