Embodiment 1

[0029] A scientific method for feeding Penaeus vannamei, specifically comprising the following steps:

[0030] (1) Treatment of breeding ponds, including drying ponds, disinfection, clearing, water intake and water cultivation, injecting clear water into the breeding ponds, and disinfecting the clear ponds thoroughly with quicklime or sodium hypochlorite. The disinfection time is 2-3 days. After disinfection, the water in the breeding ponds Put all the light on, then inject clean water, beat the tea bran to clear the field, turn on the aerator to aerate and increase oxygen, so that the dissolved oxygen in the water can be kept above 5ml / L, and then adjust the water to grow algae, and wait for the seedlings to be released;

[0031] (2) Feeding of Penaeus vannamei:

[0032] a Selected feed: crude protein content in the compound feed of Penaeus vannamei is 40% in juvenile stage, and 30% in the medium-adult stage. The prawn growth stage adopts natural animal bait and compound feed...

Embodiment 2

[0038] A scientific method for feeding Penaeus vannamei, specifically comprising the following steps:

The disinfection time is 2-3 days. After disinfection, the water in the breeding ponds Put all the light on, then inject clean water, beat the tea bran to clear the field, turn on the aerator to aerate and increase oxygen, so that the dissolved oxygen in the water can be kept above 5ml / L, and then adjust the water to grow algae, and wait for the seedlings to be released;

[0040] (2) Feeding of Penaeus vannamei:

[0041] a Selected feed: the crude protein content in the compound feed of Penaeus vannamei is 40% in juvenile stage, and 32.5% in the medium-adult stage. The prawn growth stage adopts natural animal bait and compoun...

Embodiment 3

[0047] A scientific method for feeding Penaeus vannamei, specifically comprising the following steps:

[0048] (1) Treatment of breeding ponds, including drying ponds, disinfection, clearing, water intake and water cultivation, injecting clear water into the breeding ponds, and disinfecting the clear ponds thoroughly with quicklime or sodium hypochlorite. The disinfection time is 2-3 days. After disinfection, the water in the breeding ponds Put all the light on, then inject clean water, beat the tea bran to clear the field, turn on the aerator to aerate and increase oxygen, so that the dissolved oxygen in the water can be kept above 5ml / L, and then adjust the water to grow algae, and wait for the seedlings to be released;

[0049] (2) Feeding of Penaeus vannamei:

[0050] a Selected feed: the crude protein content in the compound feed of Penaeus vannamei is 40% in juvenile stage, and 35% in the medium-adult stage. The prawn growth stage adopts natural animal bait and compound ...

Abstract

The invention discloses a penaeus vannamei scientific feeding method. The method includes following steps: (1), treating a breeding pond; (2), feeding penaeus vannamei: selecting feed, managing feeding, observing feed intake after feeding, and adjusting the feed at proper time; (3), adjusting breeding water. Bacteria benefitting and inhibiting principles are utilized, feed conversion rate is increased, and water quality deterioration risk is controlled; natural animal bait and compound feed are feed alternately, so that quick growth of penaeus vannamei can be realized, and bait coefficient canbe lowered, water eutrophication can be avoided, and intake, digestion and absorption of penaeus vannamei are facilitated; feeding quantity, feeding time and number of times can be correspondingly adjusted according to different growth stages, and the feed can be utilized to greatest extent; feed additive is used in the adult shrimp stage, so that necessary trace element is provided for penaeus vannamei, breeding environment is improved, immunity of penaeus vannamei is enhanced, survival rate of penaeus vannamei is increased, and economic benefit is increased.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a scientific feeding method for Penaeus vannamei. Background technique [0002] Penaeus vannamei is also known as vannamei shrimp. Its meat is delicious, high in protein, low in fat, rich in calcium, phosphorus, iron, selenium, zinc, magnesium, iodine and other trace elements, and rich in vitamin A, vitamin C, etc., low in sugar, low in fat and low in cholesterol. In recent years, people's demand for Penaeus vannamei has been increasing, and the output of Penaeus vannamei has gradually been unable to meet market demand. [0003] Penaeus vannamei has the characteristics of fast growth, high yield, omnivorous and so on. Feed is the main input in shrimp culture. Insufficient baiting will affect the growth of prawns and lead to a decrease in resistance; excessive baiting will waste feed, pollute water quality and bottom quality, and induce shrimp diseases. Contents of the ...
