[0037] 1.1 Experimental design
[0038] Penaeus vannamei is the first generation of SPF vannamei seedlings, purchased from Xiamen Xinrongteng Aquatic Technology Development Co., Ltd.; golden drum fish was purchased from Shanghai Chenghao Trading Co., Ltd.; water spinach was purchased from a local vegetable market in Shanghai; shrimp feed was purchased from From Guangdong Haid Group Co., Ltd., the particle size is about 2 mm, and the crude protein content is 41.0%. Corn starch is purchased from a local vegetable market in Shanghai.
[0039] The breeding pond is an outdoor cement pond with a specification of 5×3×1.2m (length×width×depth, the unit is m), and the experimental setting is T 1 , T 2 , T 3 , T 4 A total of 4 groups, each group 3 parallel. Among them, T 1 The group was the monoculture group of Penaeus vannamei, and the feed fed was the normal amount, which was set as 100%, and this group was used as the control group; T 2 The gr...

Abstract
The invention discloses a penaeus vannamei farming method combining bioflocculation technology and a multi-trophic-level integrated farming mode. The penaeus vannamei farming method combining the bioflocculation technology and the multi-trophic-level integrated farming mode includes the steps such as early-stage preparations of farming conditions, putting of penaeus vannamei and small-size fish, swamp cabbage planting, starch addition and feeding feedstuff management. According to the method, the multi-trophic-level integrated farming mode and the bioflocculation technology are innovatively applied to penaeus vannamei farming in a combining mode, namely, a multi-trophic-level integrated farming system composed of polyculture of the penaeus vannamei, the small-size fish and swamp cabbages. Starch is added in the farming system to serve as carbon source cultivation biological floccules. The levels of ammoniacal nitrogen and nitrous nitrogen in a water body are controlled through a bioflocculation action. Simultaneously, residual bait and excrement are utilized to form bacterium floccules which prawns and the small-size fish can ingest and utilize, and therefore the survival rate of the penaeus vannamei and the efficiency of feed utilization are improved. Relative to an ordinary single-farming mode, aspects of ecological benefits, economic benefits and farming effects in the farming system all achieve obvious effects.
Description
technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a method for cultivating Penaeus vannamei that combines biological flocculation technology with a multi-trophic level comprehensive cultivation mode. Background technique [0002] Penaeus vannamei, whose scientific name is Litopenaeus vannamei, has the advantages of fast growth, low nutritional requirements, and high meat yield, and has been rapidly promoted in the aquatic product market. At present, the main farming method of Penaeus vannamei is intensive intensive farming, which brings certain economic benefits but also causes increasingly serious environmental and disease outbreak problems. [0003] Integrated multi-trophic aquaculture (IMTA) of prawns is becoming very popular. Because IMTA has the advantages of high resource utilization rate, environmental protection, diverse products, continuous supply to the market, and disease prevention, it is general...
