How deep can you fish tilapia at 15-18 degrees?

The most suitable water depth for fishing tilapia is 1.5 to 3.0 meters.

Temperature: Tilapia is a warm-loving fish, with a survival temperature range of 12 to 35°C, and an optimal survival temperature of 28 to 32°C. The water temperature is lower than 28°C but higher than 12°C or higher than 32°C. ℃ but lower than 35 ℃, feeding enthusiasm gradually decreases. When the water temperature is lower than 12 ℃, tilapia will freeze to death. When fishing for tilapia, try to choose weather above 20 ℃.

Air pressure: Tilapia’s feeding enthusiasm is significantly affected by air pressure. From a numerical point of view, the optimal air pressure is 990 to 1005 hPa. From a changing trend, it is recommended to choose weather with a sudden or continuous increase in air pressure. When the air pressure drops suddenly or shows a downward trend, tilapia will be less motivated to eat or even not open their mouths. Try to avoid such weather when fishing.

To sum up, the most suitable water depth for fishing tilapia is 1.5 to 3.0 meters. The reason is that tilapia is a middle- and lower-layer fish and is active in the middle and lower layers of the water body in spring, summer and autumn, and in winter. Swimming to deep water areas to overwinter, but this is not absolute, because seasonal changes, water temperature, air pressure, water quality, bait environment, etc. will all change the water layer in which tilapia lives.
