Problems solved by technology

Shrimp is named after the fishermen used to calculate the sales of "one pair" products in history. It is distributed in shallow coastal waters with a sea water temperature above 20°C. Prawns are sea prawns, which are a unique specialty in my country. Export earns foreign exchange, and there is artificial breeding now. However, due to changes in water quality, the ability to dissolve oxygen in water bodies decreases, and extreme weather occurs frequently and lasts for a long time, making shrimp farming increasingly difficult. Often due to differences in water quality and the breeding environment at the bottom of the pond, it is easy to cause The problem of low survival rate of prawns

Embodiment 1

[0019] A culture method for improving the survival rate of prawns, comprising the following steps:

[0020] a. Choose a sunny neutral soil pond of 3 mu, which is square and arc-shaped, equipped with a central sewage system, and an aerator for every 2 mu of waterwheel type aerator, and equipped with a nano-microporous aerator at the bottom Aeration pan;

[0021] b. Mix dibromonitrilopropionamide and water in a weight ratio of 1:200 to make a sterilizing solution, clean the breeding pond with the sterilizing solution, wash the sterilized breeding pond with clear water, expose it to the sun for 6 days, and pour it into the pond When the water is released to a depth of 30cm from the water surface to the bottom of the pool, stop the water discharge;

[0022] c. Sprinkle the original ocean crystal salt evenly in the water, so that the concentration of the salt water is 12%; it can improve the survival rate of the shrimp seedlings, and the salinity will gradually decrease in the lat...

Embodiment 2

[0030] A culture method for improving the survival rate of prawns, comprising the following steps:

[0031] a. Choose a sunny neutral soil pond with 4 mu, which is square and arc-shaped, with a central sewage system, and an aerator with a waterwheel type aerator for every 2 mu, and a nano-microporous aerator at the bottom Aeration pan;

[0032] b. Mix dibromonitrilopropionamide and water in a weight ratio of 1:200 to make a sterilizing solution, clean the breeding pond with the sterilizing solution, wash the sterilized breeding pond with clear water, expose it to the sun for 8 days, and pour it into the pond When the water is released to a depth of 35cm from the water surface to the bottom of the pool, stop the water discharge;

[0033] c. Sprinkle the original ocean crystal salt evenly in the water, so that the concentration of the salt water is 14%; it can improve the survival rate of the shrimp seedlings, and the salinity will gradually decrease in the later stage, and the...

Embodiment 3

[0041] A culture method for improving the survival rate of prawns, comprising the following steps:

[0042] a. Choose a sunny neutral soil pond of 5 mu, which is square and arc-shaped, equipped with a central sewage system, and an aerator with a waterwheel type aerator for every 2 mu, and a nano-microporous aerator at the bottom Aeration pan;

[0043] b. Mix dibromonitrilopropionamide and water in a weight ratio of 1:200 to make a sterilizing solution, clean the breeding pond with the sterilizing solution, wash the sterilized breeding pond with clear water, expose it to the sun for 10 days, and pour it into the pond When the water is released to a depth of 40cm from the water surface to the bottom of the pool, stop the water discharge;

[0044] c. Sprinkle the original ocean crystal salt evenly in the water, so that the concentration of the salt water is 15%; it can improve the survival rate of the shrimp seedlings, and gradually reduce the salinity in the later stage, which ...

Abstract

The invention discloses a farming method for improving a prawn survival rate. The method comprises the following steps: fully airing the pond and disinfecting before releasing young prawns, filtering the water source, and fertilizing water; sprinkling high-efficacy EM and beneficial bacteria shrimp seed health medicines during releasing young prawns, wherein the dosage of the high-efficacy EM and beneficial bacteria shrimp seed health medicines is 1 kg per mu; feeding powdery high nutrient feed three times per day during seedling management, quantitatively feeding in fixed time, and observing the feed and prawn body length condition on the stock table; spreading mixed solution of lactic acid bacterial liquid and photosynthetic bacteria liquid into a culture pond according to a dosage of 10 liters per mu in the prawn farming period, keeping 3-7 days, starting a waterwheel aerator every day, starting on each rainy day for 4-5 hours, and starting the aerator on each sunny day for 2-3 hours. Compared with the prior art, the farming method disclosed by the invention has the advantage that the prawn survival rate is greatly improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a cultivation method for improving the survival rate of prawns. Background technique [0002] Prawns, scientific name Oriental prawns, also known as Chinese prawns and tiger prawns. Arthropoda, Crustacea, Decapod, Shrimpidae, Penaeus. Prawns are large in size and are commonly known as prawns. During the growth process, prawns have to go through dozens of molts, and every time they molt, they will get a larger growth; molting is an important symbol of the growth of prawns, which is directly affected by the external environmental conditions. Shrimp is named after the fishermen used to calculate the sales of "one pair" products in history. It is distributed in shallow coastal waters with a sea water temperature above 20°C. Prawns are sea prawns, which are a unique specialty in my country. Export earns foreign exchange, and there is artificial breeding now. However, due to chan...
