How many kilograms of feed does it take to raise 100 thousand tilapia to one kilogram?
The following are the feeding methods of tilapia feed:
The content of protein in the initial feed should be 32% ~ 35%, and the daily feeding amount should be 3% ~ 5% of the total weight of fish.
When the individual size is about 200g, the feeding amount can be adjusted to 2%~3% of the total weight of fish, and the protein content in the feed can be ensured to be 27% ~ 29%.
When the individual reaches about 300g, the tilapia enters the fastest growth period, the daily feeding amount is kept at 65438+ 0% ~ 2% of the fish weight, and the protein content in the feed is above 35%.
Feed more than twice a day, and advocate the method of feeding less times in breeding. The feeding time can be selected at 8: 00 ~ 9: 00 and 15: 00 ~ 16: 00 when the dissolved oxygen is sufficient. It is generally difficult to grasp the amount of bait, which leads to the waste of feed. If it is too small, tilapia will not have enough to eat, which is not conducive to growth. The more practical method is to set up bait tables, set up several bait tables around the pond, spread them evenly along the pond when feeding, and check the feeding situation of fish after feeding 1.5 ~ 2 hours:
In general, if the satiety rate accounts for 60% ~ 70%, feeding is reasonable.
If the satiety rate is too high, reduce the feeding amount;
If it is too low, the feed rate will increase.
At the same time, the feeding should be adjusted according to the weather, fish growth and water quality.
Feed more when the weather is good;
When the weather is bad, rainy, sultry or cold, feed less or not;
When tilapia grows vigorously and is disease-free, it should be fed more, otherwise it should be fed less;
When the water is fresh and the dissolved oxygen is sufficient, tilapia can eat normally.
When the water quality is poor and the dissolved oxygen is low, feed less or not.
