Grass carp grows fast, yields high, the market consumes large amounts, and farming techniques are easy to master. However, if the feeding and feeding technology is not scientific, even the best feed may not be able to obtain the desired results, which will affect the economic benefits of breeding. Specifically speaking, grass carp breeding feed should grasp the following points:
Palladium-selected feeds currently have feed pellets, puffed feed, and flour, but it is best to choose puffed materials, followed by pellets. General specifications for 50 grams to 100 grams of fish should use a feed particle size of 2.5 mm, 200 grams to 400 grams of fish should use a feed particle size of 3.5 mm to 5 mm, more than 500 grams of fish should use a feed particle size of 5.5 More than millimeters. If you choose improperly, too large and small particle size feed will affect the fish swallowing effect and reduce feed utilization.
Select the amount of feed according to the temperature, dissolved oxygen, water quality and other factors, select the amount of feed per day. Generally should choose the sunny day after the sun comes out 2 hours, dissolved oxygen reaches a certain time when the beginning of feeding, the effect is better, continuous rainy days, the fish floating weather as little as possible to feed or not feed.
The specific feeding amount is: When the water temperature is 18°C ​​to 20°C, the daily feeding amount accounts for about 1% to 1.5% of the total weight of the eaten fish. Water temperature at 22 °C ~ 26 °C, the amount of feed each day about 2% to 3% of the total weight of 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 accounts for about 2% to 2.5% of the total weight of the fish.
To achieve "four sets of three look" that is, timing, positioning, quantitative, qualitative, see the weather, see the water, see the fish.
With green feed, it can be fed with green feed while feeding compound feed. Green feed is beneficial to enhance fish health and reduce the cost of farming. Green fodder is better with ryegrass, Mexican corn, and high-dan grass.
Regular inspections of the food market should be conducted to see if there is surplus feed on the bottom of the water and observe the growth of grass carp so as to adjust the feed in time.
