Abstract
The invention relates to the field of aquiculture, in particular to a method for raising young litopeneaus vannamei, which comprises the following steps: naupliuses of litopeneaus vannamei are placed into a young shrimp raising pool, and rotifers and unicellular algae are raised, wherein the placement density of the naupliuses of litopeneaus vannamei is 1-100000/m<2> and areas of the young shrimp pool, a rotifer raising pool and a unicellular algae raising pool is 1:1:1. The invention keeps water environment stable by utilizing a biological water quality regulating technology, and provides excellent biological baits for the growing development of naupliuses of litopeneaus vannamei during various stages. When the naupliuses of litopeneaus vannamei are raised to young shrimps, the young shrimps are caught by a pulling net according to the production demands. The method is suitable for raising excellent and healthy young shrimps on a large scale according to concrete circumstances with low cost by adopting the invention; moreover, the method is simple, practical and easy to operation and is suitable to raising young litopeneaus vannamei in sea water pools in South China.
Description
Technical field
The present invention relates to aquaculture field, is a kind of seedling-cultivating method of Environment of Litopenaeus vannamei Low specifically.
Background technology
Referring to " the prawn seed-rearing production technology working specification " of national Ministry of Agriculture formulation and the provincial standard " Environment of Litopenaeus vannamei Low factorial seedling growth production technology working specification " of Guangdong Province's formulation.It all is the method that adopts indoor industrially to grow seedlings that at present domestic and international Environment of Litopenaeus vannamei Low is grown seedlings, this kind seedling-cultivating method requires to build the seedling rearing room of batch production, the indoor cement nursery pond that has, and be equipped with systems such as bait cultivation, water supply, air feed, electric power, rearing condition complexity, cost height.In addition, owing to grow seedlings at indoor cement pit, a large amount of artificial feed of in limited water body, throwing something and feeding, young density is big in addition, and nutrition, water environment are difficult to satisfy the physiological ecological demand that the shrimp seedling grows.The shrimp seedling quality that batch production cultivates out is difficult to guaranteed.
Summary of the invention
The object of the present invention is to provide a kind of economically feasible and Environment of Litopenaeus vannamei Low seedling-cultivating method easy and simple to handle.
For achieving the above object, the technical solution used in the present invention is:
Seedling-cultivating method: the Environment of Litopenaeus vannamei Low nauplius is thrown in the nursery pond, cultivated wheel animalcule simultaneously and feed the Environment of Litopenaeus vannamei Low nauplius; Wherein Environment of Litopenaeus vannamei Low nauplius input density is 1-10 ten thousand tails/m
2
It is 5000-10000/L that described wheel animalcule is thrown in density, and keeps wheel animalcule density; When wheel animalcule input density does not reach 5000-10000/L, add artitificial food.Described artitificial food is one or more in prawn slice, soya-bean milk and the yeast.Described wheel animalcule adopts the unit cell algae to feed.Extracting the unit cell algae with water pump during described nursing wheel animalcule directly throws something and feeds.Described unit cell algae and wheel animalcule are all adopted independent cultivation, and the area of wheel animalcule culture pond, unit cell algae culture pond and nursery pond is 1: 1: 1.Described natural temperature of growing seedlings is between 28-35 ℃.Take out wheel animalcule with the water pump circulation during described nursing Environment of Litopenaeus vannamei Low nauplius, and with throwing something and feeding after the filtration of 200-250 eye mesh screen.
The advantage that the present invention had:
1. the Environment of Litopenaeus vannamei Low culture facility is simple, cost is low.Do not need to build cement pit and supporting factorial seedling growth facility, seedling cost is 10-20 unit/ten thousand tails.
2. the pond area of growing seedlings is wide, simple to operate.South China's common sea water cultivating pool all can be cultivated the shrimp seedling, and suitable pond area of growing seedlings has more than 200,000 mu.
3. seedling raising process uses fresh and alive biological feed, satisfies the young nutritional need that grows.The shrimp seedling hepatopancrease fat that the present invention cultivates is full of, and nutritive index is good.
4. the water environment of growing seedlings is good, shrimp seedling health.In seedling raising process, every index of pond water environment and natural marine site water environment basically identical.
5. paedomorphosis is synchronous, and shrimp seedling quality is good.From nauplius (N6) to young shrimp (PL1) puberty was 8 days, no longer than 1 day; Arrive young shrimp and factorial seedling growth is the young equally, the puberty will prolong 1-3 days, and speed may differ 2-3 days.The shrimp seedling that the present invention cultivates, size are evenly, body colour is transparent, vigor good, culture the survival rate height, growth is fast.
