Autumn is the peak season for the growth of fish. At this time, the temperature is high and low during the day. In addition, autumn rain, if not properly managed, will cause the fish to grow slowly and affect fish production.
First, pay attention to the patrol pond
Every morning, fish ponds are patrolled in the morning to observe the water quality, fish activity and feeding conditions in the pond. If the eel and eel cluster in the center of the water before the sunrise, people enter the pond and enter the water. This "floating head" is a normal phenomenon and does not require rescue. If the grass carp "floats" and its body color turns yellow and is not clustered, it is not afraid of people and it must be washed immediately. At the same time, it is necessary to fight dead fish in time to remove grass debris and try to keep fish ponds clean.
Second, pay attention to impoundment
When the temperature is high, the water quality can easily become hot. When the temperature is low, the water temperature drops, and the water quality is easily deteriorated. In order to try to fill the fish ponds, it is strongly recommended that they be injected once every 3-5 days.
Third, pay attention to feeding
At this time, the temperature is low in the morning and in the evening, and the temperature is high at noon. If you feed at noon, it will exceed the temperature range of the fish. Therefore, the feed should be carried out during the 8-16 hours of the day. Avoid feeding at high water temperatures at noon.
Fourth, pay attention to water quality
Improved water quality is the key to ensuring the safety of fish stocks during the excessive rainfall period. Pools without living water sources can be poured with 1 g of bleaching powder in an amount of about 30% of water per cubic meter of water, and at the same time, appropriate amount of human waste will be applied in the morning and evening.
Fifth, pay attention to disease prevention
The mastery of fish disease is prevention. At this time the temperature changes, is the prolific period of fish enteritis, can be fed regularly bait, every 50 kg of fish with 0.7-1 grams of furazolidone, feeding for 6 days.
