Embodiment 1

[0015] Environment: 13 square meters of cement pool, a total of 20 wells are prepared (10 wells for the experiment and 10 wells for the blank control group), the water depth is 80cm, and the water temperature is 22-26°C;

[0016] Salinity: 16‰~17.3‰;

[0017] Pearl gentian seedlings (grouper): 15,000 tails, 6-7cm (05-06 sieve);

[0018] The test selects the manufacturer's compound pellet feed, 200-250ml per kilogram of slag mixture, soaks the feed, and airs it in the shade for 15 minutes before feeding.

[0019] Experimental results: The average survival rate of standard seedlings in the experimental group was 83%, and the highest was 93%. The survival rate of standard seedlings in the blank control group was 58.47%, and the survival rate of standard seedlings in the experimental group was fully increased by 24.53-34.53%.

Embodiment 2

[0021] Environment: 13 square meters of cement pool, a total of 20 wells are prepared (10 wells for the experiment and 10 wells for the blank control group), the water depth is 80cm, and the water temperature is 22-26°C;

[0022] Salinity: 16‰~17.3‰;

[0023] Large yellow croaker fry: 12000 tails, 6-7cm (05-06 sieve);

[0024] The test selects the manufacturer's compound pellet feed, 200-250ml per kilogram of slag mixture, soaks the feed, and airs it in the shade for 15 minutes before feeding.

[0025] Experimental results: The survival rate of the standard seedlings in the experimental group was 83.35%, and the highest reached 89.67%.

Abstract

The invention discloses an application of a schizochytrium limacinum wall-breaking cell wall slurry on aquatic product fry seed production. In the aquatic product fry cultivation usage, 200-250ml of schizochytrium limacinum wall-breaking cell wall slurry is added in each kilogram of fry, then is mixed and uniformly stirred, the wall-breaking cell wall slurry is stand for cooling for 15-20 minutes, and can be used for feeding after being fully absorbed. The schizochytrium limacinum wall-breaking cell wall slurry is used as a feeding material for 15-20 days, growth of beneficial bacteria in the intestine can be effectively promoted, fry is strong, survival rate of the fry can reach more than 83% or can be reached as high as more than 93%, compared with a contrast group without addition of the schizochytrium limacinum wall-breaking cell wall slurry, average survival rate can be increased to 24.53-34.53% respectively, the schizochytrium limacinum wall-breaking cell wall slurry has the advantages of economy and utility, environmental protection, good technical practicality, and obvious economic benefit, and is suitable for popularization and application of an aquatic product culture industry.

Description

technical field [0001] The invention relates to the application of a broken cell wall slurry of Schizochytrium in the cultivation of aquatic fish fry. technical background [0002] Schizochytrium, also known as Schizochytrium, belongs to a class of marine fungi belonging to Eumycota, Oomycetes, Saprolegniales, and Thraustochytriaceae. It is single-celled and spherical. Schizovibrio cells can accumulate a large amount of active substances useful to the human body, such as: the unsaturated fatty acid DHA content in the total fat is very high, reaching 35% to 68%, and more than 90% of the fatty acids are in the form of triglycerides neutral fat. There are also a small amount of EPA, ARA, DPA, etc., and the fatty acids with similar structures are low in content and easy to separate and purify. In particular, its cell wall is rich in protein, immune polysaccharides, carotenoids, vitamins, minerals, phospholipids, and about 0.3% oil (mainly DHA, ARA, DPA, etc.) and many other nu...
