Why can’t I catch fish in the Yuanjiang River during the day?

There may be several reasons why you cannot catch fish in the Yuanjiang River during the day:

1. Biological habits of fish: Fish usually seek shade to protect themselves during the hot hours of the day Protected from the sun's direct rays and high temperatures. They prefer to be active when and where water temperatures are cooler. Therefore, at noon during the day, when the water temperature is high, fish may choose to hide at the bottom or rest in aquatic plants, making it difficult to catch them.

2. Food supply: Fish usually reduce the number of times they actively forage during the day. Some fish, such as carp and silver carp, are bottom-dwelling fish and they choose to look for food at night or early in the morning. Some fish, such as bass and mandarin fish, feed on insects and prefer to look for food in aquatic plants, which reduces the chance of fishing during the day.

3. Hydrodynamic environment: During the day, the water flow in the Yuanjiang River may be relatively strong and the hydrodynamic force is greater. This can also make fishing difficult, as fish struggle to stay stable and feed in high currents.

To sum up, if you want to fish during the day, you can choose to fish in the early morning or dusk, because the water temperature at this time is relatively low, the fish are more active, and the food supply is relatively abundant. If you want to fish during the day, you can choose to do it in semi-cloudy and semi-sunny weather and in places with slow currents. Please note that the above are just some of the common reasons. Specific conditions may also be affected by local environment, season, fish species and other factors.
