First, the impact of water temperature on feeding
The temperature difference between day and night will affect the food intake of the squid on the day. The difference in daily water temperature within 3°C in the non-temperature pool is normal and will not affect the squid feed. When the temperature of the water exceeds 4°C during the season, the feeding of common carp is affected. When this happens, it is best to reduce the bait rate so as not to cause discomfort to the squid.
The main influence of seasonal temperature difference is the seasonal change of natural water temperature. We must adjust the appropriate feeding rate according to the change of natural water temperature to ensure that the eel has been in the most vigorous feeding state. Under normal conditions, the bait rate is 2.5% to 3% when the water temperature is between 24°C and 29°C. When the water temperature exceeds 30°C, the bait rate is preferably reduced to 2.2% to 2.6%. When the water temperature is between 20°C and 24°C, The bait rate is 1.6%-2.5%; when the water temperature is 14°C-20°C, the bait rate is 1%-1.6%; when the water temperature is lower than 14°C, the bait rate should also drop to 0.4%-1.0%. The above is the approximate law of the feeding rate and the water temperature, and each farmer can make slight adjustments according to his own situation.
Second, the relationship between the size of the carp and the amount of feeding
In general, the feeding rate of squid decreases as the squid grows. In the white seedling stage, the amount of white litter should be 5%-6% of carcass weight; in the dark stage, the size of the carp is approximately 500-80p, and the bait rate should be reduced to 5%. 3.5%; while the sturgeon grows to a maximum of 80-50p, the bait rate is preferably controlled at 3.5%-2.5%; when the cod comes within 15p, the feed rate should drop to 2.5%-1.5%.
Third, sudden changes in the weather will also reduce the amount of food consumed by carp
When the weather is suddenly hot, the carp feels very annoyed and may even have temporary hypoxia. Therefore, at least half of the feeding amount should be reduced in this case.
When the cold air suddenly comes, the carp will also produce discomfort. At this time, it is necessary to reduce the feed amount by more than 1/3.
In the event of heavy rain or heavy rain, it is best to stop for a meal and conduct a complete disinfection of the water to reduce some of the adverse effects of the stress response of the catfish. Http://
