The ginseng fish has the habit of building nests during its growth period. This is to facilitate spawning. So what is the reproductive and nesting habit of the ginseng fish during its growth period?
In fish with internal fertilization, the male and female are connected to the tail. For example, when cartilaginous fish reproduce, the male fish uses his fins to connect the tail to inseminate. Some fish with in vitro fertilization also exhibit similar behaviors such as mating. For example, when loaches are reproducing, the male fish wraps around the female fish; some fish chase each other with one female and one male, and the male fish uses his head to resist the female body. When the female is extremely excited, When fish lay eggs, male fish release sperm; some females and males chase each other in groups to lay eggs and release sperm to complete reproduction.
Some fish have the habit of building nests or using specific places to lay eggs, such as yellow catfish, croaker, tilapia, etc., which dig nests at the bottom of the water before spawning; black snakeheads dig nests in aquatic plants. Build a ring-shaped nest; before spawning, the male of the betta fish continuously swallows air from the water surface, and then spits out bubbles, which will form a floating nest; eels also use the bubbles spit out to build nests; the male stickleback fish uses the air infiltrated by the kidneys Mucus is used to glue fragments of aquatic plant rhizomes into a bird-like nest. The nest has entrance and internal outlets for the entry and exit of broodstock; the sand snake uses stone caves, broken earthen jars or clam shells as nests to lay eggs in leeward bays.
