The higher atmospheric pressure, the higher dissolved oxygen in water, the more active fish activities.
The influence of water temperature and atmospheric pressure is most obvious, but the influence of temperature on water temperature is lagging behind and slow, and the change of atmospheric pressure is more intuitive.
According to some research, fish activities are most active in about one hour before and after the moontransit (upper or lower), and are also active within half an hour before and after the Moonrise or Moonset.
The breeze blowing Buddha water surface increases the dissolved oxygen of water.
In addition, within one month, fishes is most active at the full moon or the new moon , least active at the first quarter or the last quarter.
