Problems solved by technology

[0003] However, Penaeus vannamei is prone to disease during the breeding process, and once the disease occurs, it will be more serious, difficult to cure, and lasts for a long time, resulting in low survival rate of Penaeus vannamei and huge losses for shrimp farmers

Embodiment 1

[0036] The cultivation method for improving the survival rate of Penaeus vannamei comprises the following preparation steps:

[0037] 1) In the early stage of breeding, feed feed A, and the daily feeding amount is 0.7g per 100 tails, divided into 3 feedings;

[0038] 2) In the middle stage of breeding, feed feed B, and the daily feeding amount is 4% of the total weight of pond shrimp, which is divided into 4 feedings;

[0039] 3) In the later stage of breeding, feed the conventional feed specially for Penaeus vannamei, and the daily feeding amount is 3% of the total weight of pond shrimp, divided into 3 feedings;

[0040] Other breeding steps follow conventional methods.

[0041] The preparation method of the feed A is as follows: take the conventional feed special for Penaeus vannamei, spray the traditional Chinese medicine liquid A, and then dry it.

[0042] The preparation method of the feed B is as follows: take the conventional feed specially for Penaeus vannamei, spray...

Embodiment 2

[0048] The cultivation method for improving the survival rate of Penaeus vannamei comprises the following preparation steps:

[0049] 1) In the early stage of breeding, Feed A is fed, and the daily feeding amount is 0.8g per 100 tails, which is divided into 4 feedings;

[0050] 2) In the middle stage of breeding, feed feed B, and the daily feeding amount is 5% of the total weight of pond shrimp, which is divided into 4 feedings;

[0051] 3) In the later stage of breeding, feed the special feed for conventional Penaeus vannamei, and the daily feeding amount is 3.5% of the total weight of pond shrimp, divided into 4 feedings;

[0052] Other breeding steps follow conventional methods.

[0053] The preparation method of the feed A is as follows: take the conventional feed special for Penaeus vannamei, spray the traditional Chinese medicine liquid A, and then dry it.

[0054] The preparation method of the feed B is as follows: take the conventional feed specially for Penaeus vann...

Embodiment 3

[0060] The cultivation method for improving the survival rate of Penaeus vannamei comprises the following preparation steps:

[0061] 1) In the early stage of breeding, Feed A is fed, and the daily feeding amount is 0.9g per 100 tails, which is divided into 3 feedings;

[0062] 2) In the middle stage of breeding, feed feed B, and the daily feeding amount is 6% of the total weight of pond shrimp, divided into 3 feedings;

[0063] 3) In the later stage of breeding, feed the conventional feed specially for Penaeus vannamei, and the daily feeding amount is 4% of the total weight of pond shrimp, divided into 3 feedings;

[0064] Other breeding steps follow conventional methods.

[0065] The preparation method of the feed A is as follows: take the conventional feed special for Penaeus vannamei, spray the traditional Chinese medicine liquid A, and then dry it.

[0066] The preparation method of the feed B is as follows: take the conventional feed specially for Penaeus vannamei, spr...

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to an aquaculture method for increasing the survival rate of penaeus vannamei boone. The aquaculture method includes preparation steps of 1), separately feeding every 100 pieces of penaeus vannamei boone with 0.7-0.9 g of feed A by 3-4 times on a daily basis at aquaculture earlier stages; 2), separately feeding the penaeus vannamei boone with feed B by 3-4 times on a daily basis at aquaculture middle stages; 3), separately feeding the penaeus vannamei boone with conventional special penaeus vannamei boone feed by 3-4 times on a daily basis at aquaculture later stages; carrying out other aquaculture steps according to conventional processes. The daily feeding quantity of the feed B accounts for 4-6% of thetotal weight of the penaeus vannamei boone in each pond. The daily feeding quantity of the conventional special penaeus vannamei boone feed accounts for 3-4% of the total weight of the penaeus vannamei boone in each pond. The aquaculture method has the advantages that traditional Chinese medicine liquid is sprayed to the conventional special penaeus vannamei boone feed at the aquaculture earlierstages and the aquaculture middle stages of the penaeus vannamei boone, synergistic effects can be realized by various raw materials of the traditional Chinese medicine liquid, and accordingly the survival rate of the penaeus vannamei boone can be effectively increased; the raw materials for the traditional Chinese medicine liquid are natural, non-toxic, green and safe, and influence on the palatability of the feed can be prevented.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a cultivation method for improving the survival rate of Penaeus vannamei. Background technique [0002] Penaeus vannamei, commonly known as White-leg shrimp or Whiteshrimp, was once translated as Penaeus vannamei. It looks like Chinese shrimp and Penaeus moji, and its average lifespan can be at least 32 months. The adult Penaeus vannamei can be up to 24cm long, with a thin carapace. The normal body color is light blue-gray, and there are no markings on the whole body. The legs are often chalky, so they are called white-legged shrimps. In terms of distribution, it belongs to Arthropod (Arthopoda), Crustacea (Crustacean), Decapoda (Decapoda), Swimming suborder (Natantia), Penacidae (Penacidae), Penaeus (Penaeus), Litopenaeus subgenus, and is a wide-temperature and wide-salt species. Sexual tropical shrimp. Vannamei is a broad-temperature and broad-halty tropical ...
