Second, the living habits of mandarin fish

Mandarin fish generally live in still water or slow-flowing water bodies, especially in lakes with lush aquatic plants. It is not very active in winter, often overwinters in deep water, and generally does not stop feeding completely. When the weather turns warm in spring, they swim to the shallow water on the rocky bank to look for food; at this time, both males and females have the habit of lying on their side in the depression at the bottom of the lake during the day, and move and look for food in the bushes at night. Feeding mainly on other fish, the feeding was poor from January to February, the most exuberant from June to July, and the feeding intensity decreased slightly during the reproductive period. Mandarin fish usually grow to 2 winter years old and reach sexual maturity at 3 winter ages in the northeast. Parent fish cluster in May-July to spawn in a gentle running water environment at night. The peak spawning period is from June to July, and the number of eggs is 3-200000 eggs.

The predation method of mandarin fish is different from that of other carnivorous fish. Mandarin fish often hide in the branches and roots of aquatic plants, or lurk in underwater ridges, culverts, or hide in the cracks between rocks, motionless, like a stone, and use its patches to confuse other fish and make them lose their guard. When the passing fish and shrimp swam near, it suddenly pounced on them and caught them. The location of mandarin fishing is very important, and the lower hook must have two conditions: one is that the current is fast, and the other is that the bottom is covered with or piled with rocks, with rock cracks and karst cave structure. This is because the rock is the gathering place for clams, snails and clams, and the habitat of this kind of crustacean molluscs is the living area of river shrimps, which provides natural food for mandarin fish, which is bound to lead to groups of mandarin fish.
