1, choice of float material.
If you catch crucian carp in a black pit, you will catch more fish every time. The float is not only sensitive, but also durable, and its comprehensive performance is very important. Nano crucian carp floating is the first choice. If you fish crucian carp in the wild, it is relatively leisure, the sensitivity of fish drift is the most important, and reed drift is the most suitable.
2. Selection of float shape.
If you are fishing for crucian carp in a black pit, slender drift is the first choice, because this kind of drift sinks quickly and can reach the finish line quickly, improving fishing efficiency. If it is wild fishing, jujube-stone float is the first choice. The action of turning over and standing in the water is very quick and clear, which can determine the water layer where the fish is, and also has a certain ability to resist running water.
3. Selection of floating length.
In mid-spring, the crucian carp will move in shallow water, so it is not necessary to fish too deep, and the length of the float is relatively short. Under normal circumstances, when the fishing depth is about half a meter to one meter, the length of crucian carp drift can reach 20~30 cm. The shallower the water, the shorter the float and sub-line.
4. Selection of lead consumption in fish bleaching.
When fishing crucian carp in black pit, in order to make the fish float and sink quickly, you can choose to eat more lead, and 2.0~2.5 grams of lead is more appropriate. If crucian carp is fished in the wild, it is most suitable to choose the lead content in fish drift between1.5 ~ 2.0 g.
Growth characteristics:
Although crucian carp is strong in vitality, omnivorous, tender and delicious in meat, about 82% individuals reach sexual maturity because of its premature sexual maturity (female fish is generally 6-8 cm and weighs 8- 10 g; Male fish generally begin to mature sexually when they are 5-6 cm and weigh 6-8 g, and when they are more than 8 cm, about 99% individuals reach sexual maturity.
It consumes a lot of nutrients for gonad development and seriously affects its growth. Under natural conditions, the average weight of female crucian carp in Liangzihu, China is 1 age 45g, 96g in 2nd instar, 327g in 3rd instar 185g, 582g in 5th instar, 68 1g in 6th instar and 803g in 7th instar.
At that time, the growth of artificially raised crucian carp in the Yangtze River valley in China was only about 65438 000 grams, and the second-year-old crucian carp was only about 200-800 grams. Due to the slow growth of crucian carp, it has not been really regarded as the object of artificial breeding for a long time. The maximum individual weight of crucian carp recorded in China is 1.25 kg, but since it was introduced to Australia, the maximum individual weight of crucian carp has exceeded 5 kg.
