Description

Technical Field

[0001] The utility model relates to the technical field of nursery reefs, in particular to a vertical shaft type continuous multi-tube type nursery reef for larvae and juveniles. Background Art

[0002] Larvae are a stage in the life cycle of fish. The development process of larvae includes the following main stages:

[0003] Embryonic period: from fertilization to hatching of fry, this period is characterized by development taking place within the egg membrane, and the nutrition required for development is completely dependent on the yolk;

[0004] Larvae: From hatching to the formation of fin rays and the development of motor organs, larvae generally lead a planktonic lifestyle;

[0005] Juvenile stage: It starts from the time when all motor organs are fully developed, until scales begin to form and the whole body is covered with scales, and the body shape and color are basically similar to those of adult fish.

[0006] Most researchers divide the developmental stages of fish larvae and juveniles into the pre-larvae stage (from hatching to the disappearance of the yolk sac), the post-larvae stage (from the disappearance of the yolk sac to the complete development of the fin rays), and the juvenile stage (from the initial formation of each fin ray or the appearance of scales to the complete coverage of scales). Some scholars also use other obvious characteristics as the classification criteria for the development of larvae and juveniles of fish with few or no scales. In summary, larvae and juveniles are an important stage of fish development, which is located between the embryonic stage and the adult stage, and is an indispensable part of the fish life cycle. Therefore, the cultivation of larvae and juveniles is particularly important. Utility Model Content
