How to feed your catfish ?

1.Choose a palatable feed

The feed for catfish should be selected from regular large-scale manufacturers and companies to ensure the stability of quality of feed pellet. At present, there are pellets, extruded feeds by fish feed extruder, and powdered feeds, but it is best to choose extruded feeds, followed by pellets. Then select the particle size of the pellet feed according to the specifications of the catfish in the water body to make the grass carp palatable to swallow. Generally, fish with a size of 50 to 100 grams should choose a feed size of 2.5 mm, for fish with 200 to 400 grams, a feed size of 3.5 to 5 mm, and for fish over 500 grams, the feed size should be 5.5 mm or more. If you choose improperly, feed with too large or small particle size will affect the fish swallowing effect and reduce the feed utilization rate.

2.Choose the amount of feeding

According to factors such as temperature, dissolved oxygen, water quality, etc., choose the daily feed amount. Generally, you should choose to start feeding when the dissolved oxygen reaches a certain time,like the sun comes out for 2 hours on a sunny day , the effect is better. Feeding as little as possible or not feeding as much as possible on continuous rainy days and fish floating head weather.

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 fish eaten. The water temperature is 22℃~ 26℃ , and the daily feeding amount accounts for about 2% to 3% of the total weight of the fish eaten. When the water temperature is between 26°C and 32°C, the daily feeding amount accounts for about 3% to 5% of the total weight of the fish eaten. When the water temperature is above "32℃", the daily feeding amount will account for about 2% to 2.5% of the total weight of the fish eaten.

3.Check regularly

That is, timing, positioning, quantification, and quality, watching the weather, watching the water quality, and watching the fish. It is generally required to be equipped with a bait machine for feeding, so that the specifications of the reared fish are neat and consistent. When domesticated fish eat food, they must float on the surface of the water to grab food, otherwise they cannot be fed. Generally, the maximum weight of a fish feeding machine is about 5000 kg. The bait-dropping machine is set in the range of 2 to 4 meters in the depth of the water .

4.Match green fodder

While feeding the compound feed, it can be fed with green feed. Green fodder is conducive to enhancing the physique of fish and reducing the cost of breeding. Green fodder is preferably ryegrass, corn, and alfalfa. Feed the green feed once a day, preferably 2 hours after the compound feed.

5.Regularly check the food court

It is necessary to observe the growth of catfish by observing whether there is excess feed at the bottom of the water, so as to adjust the weight and quality of feed in time.
