Problems solved by technology

[0004] However, with the continuous development of the economy, the number of wild turbot can no longer meet the growing needs of people. It is an inevitable choice to meet the market demand to increase the output of turbot through intensive farming.
In the intensive breeding mode of turbot, feeding feed promotes the growth of turbot, shortens the breeding cycle, and greatly increases the output of turbot. However, during the breeding process, the amount of ammonia nitrogen in the water body increases and the oxygen content in the water body decreases. , harmful bacteria grow, turbot is prone to disease, and the survival rate is reduced

Embodiment 1

[0021] A turbot culture method, comprising:

[0022] (1) Pond construction: In January 2017, in the waters of Qinzhou Port, Guangxi, a pond with an area of ​​3 acres of mixed sand and mud was selected as the breeding pond, and the breeding pond was dredged, loosened, and exposed to the sun for 15 days , then introduce seawater to soak the bottom of the pool for 3 days, plant seaweed on the bottom of the pool, and then increase the amount of seawater in the pool to make the water depth reach 1.5m;

[0023] (2) Fertilization: Choose a 20m3 container as a seedling container, inject sterilized fresh seawater, then add 3ml of semen to 1×106~108 eggs, stir quickly to make the sperm and eggs fully contact, then let it stand for 5 minutes, and then add After passing through fresh seawater, let it stand for 15 minutes, separate the floating eggs from the sedimented eggs, and the floating eggs are sterilized for later use;

[0024] (3) Hatching: select a 20m3 container as a seedling co...

Embodiment 2

[0035] A turbot culture method, comprising:

[0036] (1) Pond construction: In February 2017, in the waters of Sanniang Bay, Qinzhou, Guangxi, a 5-acre pond with mixed sand and mud as the bottom was selected as the aquaculture pond, and the aquaculture pond was desilted, loosened the bottom of the pond, and exposed to the sun for 20 days , then introduce seawater to soak the bottom of the pool for 5 days, plant seaweed on the bottom of the pool, and then increase the amount of seawater in the pool to make the water depth reach 2.5m;

[0037] (2) Fertilization: Choose a 30m3 container as a seedling container, inject sterilized fresh seawater, then add 6ml of semen to 1×108 eggs, stir quickly to make the sperm and eggs fully contact, then let it stand for 5 minutes, and then add fresh Seawater, stand still for 25 minutes, the floating eggs and sediment eggs are separated, and the floating eggs are sterilized for later use;

[0038] (3) Hatching: select a 30m3 container as a see...

Embodiment 3

[0049] A turbot culture method, comprising:

[0050] (1) Pond construction: In March 2017, in the Maowei Sea area of ​​Qinzhou, Guangxi, a 7-acre pond with mixed sand and mud as the bottom was selected as the breeding pond. The breeding pond was desilted, loosened the bottom of the pond, and exposed to the sun for 18 days. , and then introduce seawater to soak the bottom of the pool for 4 days, plant seaweed on the bottom of the pool, and then increase the amount of seawater in the pool to make the water depth reach 2m;

[0051] (2) Fertilization: choose a 25m3 container as a seedling container, inject sterilized fresh seawater, then add 4ml of semen to 1×105 eggs, stir quickly to make the sperm and eggs fully contact, then let it stand for 5 minutes, and then add fresh Seawater, let stand for 20 minutes, separate the floating eggs from the precipitated eggs, and the floating eggs are sterilized for later use;

Abstract

The invention discloses a turbot cultivation method. The turbot cultivation method includes the steps of firstly, building a pond; secondly, performing fertilization; thirdly, performing incubation; fourthly, cultivating fry; fifthly, adding bait and controlling illumination; sixthly, controlling water; seventhly, controlling diseases. The turbot cultivation method has the advantages that fry acquiring efficiency is increased, turbot growth speed and survival rate are increased, the probability of turbot diseases is reduced, and cultivation cost is lowered; in addition, the method is simple tooperate, quick in action and easy to achieve intensive cultivation.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a turbot breeding method. Background technique [0002] Turbot is mainly produced on the east coast of the Atlantic Ocean. It is a rare low-temperature economic fish and one of the unique and valuable fish species on the Northeast Atlantic coast. The natural distribution ranges from Iceland in the north to the European coast near Morocco in the south. It is relatively produced in the North Sea, Baltic Sea, Iceland and Scandinavia. It is one of the world's recognized high-quality flounder. Its body is flat and slightly diamond-shaped, with black and brown patterns faintly visible in the brown. It is also called "butterflyfish" because of its graceful posture when swimming, like a butterfly in the water. It is a marine bottom-dwelling fish of the genus Platypteridae of the order Plaiceidae of the order Osteophytes. [0003] Turbot fish has a high content of colloidal protein, delici...
