Breeding habits vary greatly in growth rates due to different water areas. But in general, Jiangnan is faster than the north. In the natural waters, the largest individual length of the earthworm can reach more than 800 millimeters and weighs 7.5 kilograms. Sexual maturation earlier, 2nd-age sexual maturity, sexual maturity, the smallest individual 210 mm, weighing 250 grams. Batches of spawning fish are spawned repeatedly throughout their lives. Spawning period from May to August, a few can extend to August. Spawn more at night, eggs floating, round beads, orange, with oil balls. The egg diameter is 1.2-1.4 mm. After fertilization, the ovary expands and the egg diameter is about 2 mm. The fertility is generally between 2.7 and 21.3 thousand grains. The number of fertilized eggs is lower than the size of the fish body. The temperature of 21-24°C can be hatched after 72 hours, and the newly hatched larvae are 4.2-4.4 mm long. Carnivorous benthic ferocious fish, camping feeding method. It mainly eats small fish and shrimp. The newly hatched larvae will eat large zooplankton and other fish larvae immediately after the disappearance of the yolk sac. When the body length is 40-50ypoy, shrimps will be preyed. When the body length is 95 mm, small fishes will also be eaten in addition to the shrimps. Intensity of feeding is strongest in summer and breeds?
