Problems solved by technology

[0003] There are problems such as large amount of dirt and impurities discharged, slow growth rate, low yield, and poor immune performance in the existing breeding process of basilisk shrimp. Therefore, there is an urgent need for a cultivation method of basilisk prawns, so that the yield of basilisk shrimps is higher and the quality is better. Good, strong immune performance, to meet market demand

Embodiment 1

[0023] A method for ecological cultivation of basal shrimp, comprising the following steps:

[0024] S1. Breeding pond pretreatment: Choose a leeward and sunny place to build the pond. The thickness of the silt at the bottom of the pond should be more than 20cm. Exposure to the sun for 15-20 days, disinfection, water injection and fertilization, planting Hydrilla verticillium, duckweed, and water peanuts at the bottom of the pond, with a coverage rate of 45- 50%; control pool water temperature at 15-18°C, pH at 7-8, and salinity at 3‰.

[0025] Put 350kg of fermented livestock and poultry manure, 12kg of urea, 22kg of coconut shell powder, and 35kg of straw powder.

[0026] S2. Desalination of shrimp seedlings: select the shrimp seedlings of the base wall, desalinate the shrimp seedlings, reduce the salinity by 1‰ each time, and test the water at 1000 tails / m³ after each reduction of the salinity. The water test time is 24 hours each time, and the survival rate When the water...

[0031] A method for ecological cultivation of basal shrimp, comprising the following steps:

[0032] S1. Breeding pond pretreatment: choose a leeward and sunny place to build the pond, the thickness of the silt at the bottom of the pond should be more than 20cm, expose to the sun for 15-20 days, disinfect, inject water and fertilize, plant Hydrilla verticillium and Elodea at the bottom of the pond, and the coverage rate is 45-50% ; Control pool water temperature at 15-18°C, pH at 7-8, and salinity at 0.5‰.

[0033] Put 250kg of fermented livestock and poultry manure, 10kg of urea, 12kg of coconut shell powder, and 30kg of straw powder.

[0034] S2. Desalination of shrimp seedlings: select the shrimp seedlings of the base wall, desalinate the shrimp seedlings, reduce the salinity by 2‰ each time, and test the water at 2000 tails / m³ after each reduction of the salinity. The water test time is 12 hours each time, and the survival rate When the water is above 90%, the results of ...

Abstract

The invention discloses an ecological culture method of metapenaeus ensis. The ecological culture method comprises the following steps of pretreatment of a culture pond, desalination of young metapenaeus ensis, feeding and water quality management. According to the ecological culture method of the metapenaeus ensis, desalination treatment is carried out on the young metapenaeus ensis, and therefore the metapenaeus ensis can better adapt to a fresh water environment; and meanwhile, the growth of the metapenaeus ensis is divided into three stages for feeding, the reasonable feeding method and feed can promote rapid growth of the young metapenaeus ensis and improve the disease resistance and quality of the metapenaeus ensis, the culture cost is obviously reduced compared with an existing method, the culture profit is remarkably increased, development of the aquaculture industry can be promoted, farmers are driven to become rich, and good economic benefits, social benefits and ecological benefits are achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an ecological breeding method for gimai shrimp. Background technique [0002] Jiwei shrimp is famous for its thin shell, fat body, tender meat and delicious taste. Shrimp is rich in nutrients. Its meat is soft and easy to digest. It is an excellent food for people who are weak and need to take care of themselves after illness. Shrimp is rich in magnesium, which can protect the cardiovascular system well and reduce blood cholesterol levels. , prevent arteriosclerosis, and at the same time expand coronary arteries, which is beneficial to prevent high blood pressure and myocardial infarction; shrimp meat also nourishes kidney and strengthens yang, promotes milk and anti-toxin, nourishes blood and solidifies essence, removes blood stasis and detoxifies, nourishes qi and nourishes yang, dredges collaterals and relieves pain , appetizers and phlegm and other effects. [0003] There are pro...
