What is the suitable temperature for grass carp fishing?

Grass carp is a common freshwater fish, commonly known as pomfret, grass pomfret, pomfret and so on. It is named because it mainly feeds on aquatic plants. Widely distributed in ponds, streams, rivers, lakes and reservoirs all over the country. The common individual is 5 ~ 10 kg, and the largest individual can reach more than 40 kg. Let's take a look at the suitable temperature for grass carp fishing!

First, eating habits

Grass carp is a herbivorous fish, mainly feeding on zooplankton, aquatic insects, algae, duckweed, etc. In adolescence. When the body length is greater than 10 cm, it completely feeds on aquatic higher plants, and its feeding enthusiasm is related to water temperature, water quality and other factors, among which the maximum food intake is 25 ~ 30℃, and the food intake is obviously reduced when the water temperature is higher than 32℃ or lower than 20℃.

Second, the optimal temperature.

The optimum temperature for fishing grass carp is 20 ~ 32℃, when the grass carp has the highest feeding enthusiasm. When the temperature is higher than 32℃ or lower than 20℃, the grass carp's feeding enthusiasm gradually weakens, and when the temperature is higher than 35℃ or lower than 5℃, the grass carp completely stops eating. From a year's time, the best time to catch grass carp is from May to September, especially in the weather with long sunny days, early rain, showers and rain in Mao Mao.

Thirdly, the air pressure is discussed.

1, height: the optimum air pressure for grass carp fishing is 990 ~ 1005 hectopascals. In this range, the higher the air pressure, the higher the feeding enthusiasm of grass carp, while the lower the feeding enthusiasm of grass carp, but this is not absolute. For example, it is good to fish in the plateau area where the air pressure is below 990 hectopascals, because the fish in the plateau area have adapted to the low pressure environment.

2. Rise and fall: the influence of air pressure rise and fall is more obvious than that of air pressure level. Generally, when the air pressure rises, the fish's feeding enthusiasm is high, and when the air pressure drops, the fish's feeding enthusiasm is poor. For example, if the air pressure drops by more than 500 Pa a day, basically no fish can be caught, and if the air pressure rises by more than 500 Pa for one or two consecutive days, the fish will often bite the hook crazily.

Fourth, the weather.

1, rainy day in Mao Mao: rainy day in Mao Mao is most suitable for grass carp fishing, especially in Mao Mao, because rain will increase dissolved oxygen in water, and grass carp has a very high enthusiasm for eating under high dissolved oxygen.

2. After the rainstorm: It is most suitable for grass carp fishing after the rainstorm, because the rainstorm will wash the food into the water, and the dissolved oxygen in the water will increase obviously after the rain. At this time, it is easiest to catch big grass carp at the water inlet.

3. Thunderstorm: Thunderstorm weather is not suitable for grass carp fishing. One is that grass carp will hide in deep water in thunderstorm days, and the other is that fishing in thunderstorm days is very dangerous. The fishing rod erected high is simply a lightning rod.
