In fact, most of the rainfall did not enter the fishponds because the vegetation, which was also affected by drought, absorbed it.

Due to the prolonged heat, the evaporation loss is significant, as the water level in the lakes can drop by as much as 2-3 cm on a warm summer day.

In many places, the operating water level of fishponds is less than 50%.

In the narrowed aquatic habitat, the damage from fish-eating birds is also more significant, as offspring cannot hide from the wading birds so easily in the shallower water.
