When the pond conditions are bad (such as weather, water quality, etc.). ), how to grasp the feeding amount?

Pond conditions mainly refer to climate, water quality and water temperature. Generally speaking, we need to grasp the following three points:

(1) Stop feeding or halve feeding in rainy days.

Because, in rainy weather, the water temperature will suddenly drop, lack of sunlight, photosynthesis will weaken, dissolved oxygen in water will also drop, and the sudden change of water environment will affect the digestion and absorption of tilapia. Therefore, feeding at this time not only wastes feed, but also easily causes diseases of tilapia. (2) The water quality is too strong to feed.

When the water quality is too strong, the plankton in the water body is often rich and the oxygen consumption is relatively large, so the dissolved oxygen in the water body is relatively insufficient. Tilapia in this water body is easy to float and the feed utilization rate is low. Reducing the feeding amount can also make tilapia eat excess plankton, thus achieving the effect of regulating water quality. (3) If the water temperature is too low or too high, the feeding amount should be reduced.

Aquatic animals are sensitive to changes in water temperature. When the water temperature is lower than 13℃ in winter, tilapia has stopped feeding, and when the water temperature drops, the feeding amount should be reduced appropriately; When the water temperature is higher than 32℃, the food intake of tilapia is also decreasing, and when the water temperature is higher than 36℃, tilapia hardly eats. 25 ~ 32℃ is the suitable feeding water temperature for tilapia.

In addition, the feeding amount of tilapia ponds should be adjusted before and after fishing. Generally, the feeding is stopped on the day before the fish is taken out, and the feeding amount is halved on the second day after the fish is taken out, until the fourth day.
