Embodiment

[0064] (1) Test time and place: The test was carried out on May 26, 2019 in three open-air ponds in Wangcun Fishing Ground, Xiqing District, Tianjin. The three ponds have an area of ​​40 mu (1 # ), 30 acres (2 # ), 50 acres (3 # ).

[0065] (2) Test pond conditions:

[0066] The three ponds are intensive shrimp ponds. The situation of releasing seedlings in the three ponds and feeding the species of feed were consistent. All three ponds had been drained the previous winter before the trial began.

[0067] (3) Breeding process:

[0068] randomly select 1 # Pond as a test pond, 2 # and 3 # Ponds were control ponds. The 1# pond is managed according to the methods and principles mentioned above, and more microecological preparations are used to replace part of the compound feed with biological bait. 2 # and 3 # Ponds were cultured according to conventional methods.

[0069] Three ponds were applied fermented manure 3kg / mu. Put the seedlings into the water, the depth ...

Abstract

The invention belongs to the technical field of aquatic ecological cultivation, and in particular relates to a method for ecologically cultivating Litopenaeus vannamei with live bait instead of part of the feed, which is characterized in that it comprises: 1) applying fermented manure at the bottom of the pond as the base fertilizer, and the water depth before releasing the seedlings is 60 ‑80cm, carry out disinfection treatment; 2) release seedlings: apply compound microbial preparations, so that shrimp seedlings can be released at the peak of rotifers, and grass carp will be released 15 days after shrimp seedlings are released; 3) 30 days to 90 days after feeding shrimp seedlings, keep them in the pond 4) Harvesting shrimp: continue to breed for 30 days, mainly feeding with compound feed, supplemented by ingesting biological bait, and using feed to lure the shrimp when the body length is more than 15cm. Shrimp, harvested Litopenaeus vannamei. The beneficial effects of the invention are: more energy in the ecological cycle flows into the cultured products, promotes the cycle of the ecological environment, reduces environmental pollution, reduces feeding of feed, and saves cost.

Description

technical field [0001] The invention belongs to the technical field of aquatic ecological cultivation, and in particular relates to a method for ecological cultivation of Litopenaeus vannamei by using live bait instead of part of feed. Background technique [0002] Litopenaeus vannamei has a wide and mixed diet. For larvae living in planktonic life in natural sea areas, the proportion of plant-based bait in the food composition is relatively high, such as algae, humus, protozoa, etc. After metamorphosis into adult shrimp, they can eat various animal and plant-based bait in the following order: algae, protozoa , Rotifers, Cladocera, Copepods, etc. Under the conditions of artificial breeding, rotifers, artemia, egg yolk or shrimp slices can be fed to juvenile shrimp, and artificial compound feed can be fed to juvenile shrimp and adult shrimp. [0003] According to reports, Litopenaeus vannamei has strong resistance to rough feeding, and the level of animal protein in the com...
