Calculated on 1 mu of grassland, it produces 12,000 kilograms of fresh grass per mu. It can produce 350-400 kilograms of grass-eating fish, 100-130 kilograms of flower-bearing whitefish, 23-28 bait, and a production value of 2,800-3,250 yuan.
Calculated in 1 mu grain field, the per mu rice and wheat 900 kg, the market output value of 1200 or so, the effectiveness of 800 yuan; if the food fish, can produce 250-300 kilograms of eat fish, 80-100 kilograms of accompany flower Bai Bai, feed coefficient 2.3 -3.1, can create a production value of 2050-2440 yuan.
Contrast: The ratio of grass-raising fish to grain-growing is increased by 1600-2050 yuan; the ratio of grass-cultivated fish to fish-reared fish is increased by 750-810 yuan.
The benefits of grass-fish farming:
1. It can make full use of waste resources (Ikechi, Chipo, Gap, Tenland, etc.), low-lying land, and low-yield farmland;
2, the cost is low, only grass species, fertilizers and labor costs, no disease;
3. The quality of aquatic products kept is good and the market is selling well;
4. Reduce costs and increase efficiency, promote fishery efficiency and increase farmers' income.

The main features:
1)Ideal cold light effects
Using the new LED cold light source, ensure energy saving and environmental protection and long service life up to 80,000hours and more.
The temperature increase of surgeon`s head below 1℃. LED do not engender infrared ray and ultraviolet radiation, without the temperature
rise and tissue damage caused by halogen shadowless light, also it can accelerate the wound healing after surgery, and without Radiation pollution.
With color temperature constant and soft, LED is very close to the sunshine.
1) Excellent shadowless effect
Lamp with the most scientific radian and Multi point light source design, ensure better uniform illuminance. When the lamps are partially occluded,
also can achieve perfect shadowless effect.Lamp panel radius of gyration ≥182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination.
2) Excellent deep lighting
It is based on modularize method by Computer Aided Design, focused to irradiating with more beams of LED. It produces the deep lighting which beams
more than 1200cm,the illumination of center up to 180,000Lux or more, and offer the color temperature that can be adjusted from 3700K to 5000K which
is close to sunshine. Absolutely, it really reflects the color of human tissue and satisfied by all kinds of operating light needs.
3) Advanced control system
The use of liquid crystal display button control, to meet the needs of the medical staff of different patients with the brightness of the operation.
It offers illuminance memory function.
It does not effect using when a single circuit or one bulb is broken.
4) Universal suspension system
Rotating arm, a new type of alloy material is made of eight edge type.
Balanced system using imported arm module, more than 5 group universal joints, every cantilever must has more than 3 joints which can be rotated in 360°,
The structure is light, easy to manipulate, accurate positioning, can provide the maximum range of regulation.The equipped with fatigue correcting unit and
fix position hand handle device, easy to fix position after long time use.
5) Modern laminar lamp
The thickest part of lamp-chimney is not more than 10cm.
The lamp-chimney is made of ABS, The handle on the central of lamp can be detachable, can take high temperature (≤ 134°C) sterilization treatment,
easily adjust, flexible fixed.
