Embodiment 1

[0023] 1. Materials and methods

[0024] 1. Test material

[0025] The test was carried out in the circulating water workshop of Zhenyuan Aquatic Products Co., Ltd., Jieyang City, Guangdong Province. On March 3, 2017, 30,000 larvae were purchased from a nursery in Hubei and placed in three 1×1×1m cages, with 10,000 fish in each cage. During this period, the consumption and opening of yolk and oil droplets were observed. If necessary, supplement exogenous nutrition in time.

[0026] The feed used in this test was developed by the applicant, and it was microencapsulated feed for juvenile sturgeon larvae, code-named A2.

[0027] Concrete formula and preparation method are:

[0028] Specific formula:

[0029] In terms of mass fraction, it includes chicken powder 20%, sandworm 20%, egg powder 10%, yeast powder 1%, Artemia 10%, oyster 6%, fish oil 3%, soybean lecithin powder 1%, vitamin mixture 1%, Casein 5%, Antarctic krill 10%, mineral element mixture 2%, microbial preparatio...

Embodiment 2

[0069] Spoon-kissed sturgeon larvae microcapsule opening feed, calculated by mass fraction, includes chicken powder 20%, sandworm 25%, egg powder 8%, yeast powder 2%, artemia 8%, oyster 7%, fish oil 2%, soybean lecithin Powder 2%, vitamin mixture 1%, casein 4%, Antarctic krill 8%, mineral element mixture 2%, microbial preparation 1%, EPA 6%, DHA 4%.

[0070] Its preparation method is with embodiment 1.

Embodiment 3

[0072] Spoon-kissed sturgeon larvae microcapsule opening feed, calculated by mass fraction, includes chicken powder 25%, sandworm 15%, egg powder 8%, yeast powder 1%, Artemia 12%, oyster 5%, fish oil 4%, soybean lecithin Powder 1%, vitamin mixture 2%, casein 2%, Antarctic krill 12%, mineral element mixture 1%, microbial preparation 2%, EPA 4%, DHA 6%.

[0073] Its preparation method is with embodiment 1.

Abstract

The invention discloses a microcapsule starter feed for paddlefish larvae and a preparation method of the microcapsule starter feed. The feed comprises the following components in percentage by mass: 15-25% of chicken meal, 15-25% of sandworm, 8-12% of egg powder, 1-2% of yeast powder, 8-12% of artemia, 5-7% of oyster, 2-4% of fish oil, 1-2% of soybean lecithin powder, 1-2% of a vitamin mixture, 2-4% of casein, 8-12% of euphausia superba, 1-2% of a mineral element mixture, 1-2% of a microbial preparation, 4-6% of EPA and 4-6% of DHA. The paddlefish larva microcapsule starter feed is good in breeding effect, the link of transferring feed after live bait feeding can be reduced, the breeding process is simplified, large-scale intensive breeding and healthy and rapid development of the fry industry are promoted, and the paddlefish larva microcapsule starter feed has good practical significance.

Description

technical field [0001] The invention belongs to the field of opening bait for fish fry, and in particular relates to a microcapsule opening bait for juvenile sturgeon larvae and a preparation method thereof. Background technique [0002] Polyodon spathula (Polyodon spathula), also known as white sturgeon and duck-billed sturgeon, belongs to the family Acipenseridae and is a large freshwater economic fish. Spoon-nose sturgeon feeds on zooplankton throughout its life. It is a wide-tempered fish with strong adaptability and fast growth. It is native to the waters of the Mississippi River in the United States. It was introduced from the United States by the Hubei Provincial Fisheries Bureau in 1988 and the sample was successful. In the traditional breeding of sturgeon fry, the biological bait is generally fed first, and then the feed is transferred to the artificial compound feed. With the increase in the demand for fry and the cost of zooplankton cultivation, live bait has bec...
