m3。
The operation principle of the present invention given below：
Using the suction-operated of soil, adsorb the residual bait and excrement produced in nursery pond so as to bottom of pond is deposited to, so as to not
Harmful organic matter can be produced in water body.Generally, Pseudosciaena crocea Fry happiness cluster, easily causes lacking for water body local
Oxygen, and after loess filter liquor of splashing water to become comparison muddy, transparency is reduced, and fry is more evenly distributed in water, can subtract
The risk of few local water hypoxia, improves the cultivation density of fry.
Beneficial effects of the present invention are：
1st, hang present invention achieves simply using common loess filter liquor and just having reached solid particle in removal seedling water
The purpose of the oily matter such as float and fish oil, greatly reduces seedling cost.
2nd, conventional large yellow croaker nursery needs daily 100% quantity of exchanged water, and the present invention can greatly reduce quantity of exchanged water, daily
Only change 30% or so water.
3rd, the present invention improves seedling density, and water can become that comparison is muddy after loess filter liquor of splashing, and fry is in water
Be more evenly distributed, will not cluster cause ischaemia, the seedling density of large yellow croaker can be improved：The fry rearing of total length 2cm is close
Degree can reach 1.8 ten thousand tails/m3Left and right, than ever 0.8 ten thousand tails/m3Fry density improve 2 times or so.
4th, the invention enables the survival rate of large yellow croaker nursery reaches 37.5% or so, improve than conventional nursery survival rate
15% or so.
5th, the body colour of the Pseudosciaena crocea Fry that the present invention is cultivated is more nearly the body colour-buff of Wild Rhubarb fish.
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.
Embodiment 1 is produced Co., Ltd's large yellow croaker nursery and carries out the enforcement of concrete scheme in the rich shampoo of Fujian Province's Ningde City.
Nursery stage feeds utilized fish oil content is higher, after feeding feed, the things such as fish oil in feed is had in water body
Matter is remained, and causes condition of water quality poor, makes water body become sticky, anoxic.After loess filter liquor of splashing, clay can adsorb the fish in water
The material such as oil and microparticle so as to be deposited to bottom of pond；It is muddy that water body becomes comparison, and transparency is reduced, and fry is distributed more in water
