Grass carp grow fast, yield is high, market consumption is large, and farming technology is easy to master. However, if feeding feed is unscientific, even the best feed may not be able to get the desired effect, which will affect the economic benefits of farming. Specifically, grass carp farming feed should be fed the following points:
1. Choosing a palatable feed: The feed of grass carp should use regular large manufacturers and company products to ensure the stability of quality. At present, the feed has pellets, puffed feed, and powder, but it is best to choose a puffed material, followed by a pellet. Then, according to the size of the grass carp in the water body, the particle size of the pellet feed is selected, so that the grass carp can be swallowed. For fish with a general specification of 50-100 grams, the feed size should be 2.5 mm. For fish with 200-400 grams, the feed size should be 3.5-5 mm. For fish above 500 g, the feed size should be 5.5 mm or more. If improperly selected, feeds that are too large or too small in size will affect the fish swallowing effect and reduce feed utilization.
2. Select the feeding amount: According to the temperature, dissolved oxygen, water quality and other factors, choose the daily feed amount. Generally, you should choose the sunny day when the sun comes out for 2 hours. When the dissolved oxygen reaches a certain level, it starts to feed. The effect is good. The rainy day and the floating head of the fish are fed as little or as little as possible. The specific feeding amount is: when the water temperature is between 18 ° C and 20 ° C, the daily feeding amount accounts for about 1% to 1.5% of the total weight of the fish. The water temperature is between 22 ° C and 26 ° C, and the daily feeding amount is about 2% to 3% of the total weight of the fish. When the water temperature is between 26 ° C and 32 ° C, the daily feeding amount is about 3% to 5% of the total weight of the fish. When the water temperature is above 32 °C, the daily feeding amount is about 2% to 2.5% of the total weight of the fish.
3. To achieve "four fixed three look": that is, timing, positioning, quantitative, qualitative, weather, water quality, fish watching. It is generally required to configure the feeding machine to feed, so that the specifications of the cultured fish are neat and uniform. When domesticated fish are ingested, the fish must be hunted on the floating surface, otherwise the feed cannot be fed. Generally, a feeding machine can feed a maximum of about 5,000 kg of fish. The feeding machine is set in the water depth of 2 to 4 meters.
4 with green feed: While feeding the compound feed, it can be fed with the feeding of green grass carp feed. Green feed is beneficial to enhance fish quality and reduce farming costs. Green fodder is best for ryegrass, Mexican corn, and high-density grass. Feed the green material once a day, preferably 2 hours after feeding the compound feed, or feed at night.
5. Regularly check the food field: Observe the growth of grass carp by checking the remaining feed at the bottom of the water to adjust the weight and quality of the feed.

Gabions & Reno Mattresses are rectangular baskets made of heavily galvanized, double twisted, steel Woven Wire Mesh. The single unit constructed baskets are assembled, laced together and then filled with stone to form a monolithic structure. Gabions and Reno mattresses are used for retaining walls, sound barriers, channel linings, slope stabilization, dams and weirs. They are particularly effective in restoring the environment and promoting vegetation growth.
Plastic coated wire, Galvanized Wire stone cage wire mesh, is not only used as the stone net cage, but also as the high quality construction materials. widely used in highways, railways, greening Fence hillside net cage, flood fighting net cage, revet fence, zoo fence, well and alley fence etc. Meanwhile it can improve the stability of hillside, preventing the riverbed from washing out.On the maintenance of neighborhood environment and waterhead, it also have the effect of controlling the flowing quantity,preventing the watersource from flowing, protecting and governing the zoology environment.
