AI Technical Summary
The prior art is difficult to effectively protect the scattered fish from invasion and harm from large fish, and it is also difficult to provide sufficient natural nutrients and a safe environment to promote the healthy growth of the scattered fish.
A multi-row tile-type larval fish conservation reef with protective nets around it was designed. A protective net made of flexible metal mesh was added to the outside of the conservation reef group to prevent the invasion of large fish. The metal frame and tile-like plate body increase the seawater contact area and algae reproduction, provide natural nutrients, and facilitate the shuttle of larvae and juvenile fish to feed and resist predators.
It effectively prevents large fish from harming larvae and juveniles, increases seawater contact area and algae reproduction, provides natural nutrients, and provides a safe environment for larvae and juveniles to feed and move.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nursery reefs, in particular to a multi-row tile-type nursery reef for larvae and juveniles with protection nets arranged around it. 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
[0007] In view of the problems existing in the prior art, the utility model provides a multi-row tile-type fish larvae and juveniles conservation reef with protective nets on all sides to solve at least one of the above technical problems.
[0008] The technical solution of the utility model is: a multi-row tile-type larvae and juvenile fish conservation reef with protective nets on all sides, including a conservation reef group, characterized in that a protective net is arranged on the outside of the conservation reef group, the protective net is surrounded in a square structure, and a column is respectively arranged at the four corners of the protective net, and the column is connected to the corner of the protective net through a fixing rope;
[0009] The conservation reef group includes multiple conservation reefs, and the conservation reefs include a metal frame. A support rod is provided on the back of the metal frame, one end of the support rod is fixed to the metal frame, and the other end of the support rod is inserted into the bottom layer. The metal frame is arranged obliquely in the protection net through the support rod. A plate body made of concrete is provided inside the metal frame. The plate bodies are stacked up and down and arranged inside the metal frame. A partition is provided between two adjacent plate bodies, and the partition is fixedly connected to the metal frame. The plate body has a tile-like structure.
[0010] The utility model can prevent the invasion of large fish from causing harm to the fry and juvenile fish in the conservation reefs by adding a protective net on the outer side of the conservation reef group. The metal frames arranged obliquely can better increase the contact area with the seawater, so that the surface of the board body is more likely to produce algae reproduction, providing natural nutrients for the fry and juvenile fish. The tile-shaped board body can facilitate the fry and juvenile fish to shuttle and forage, and can also play an effect of resisting enemies.
[0011] Further preferably, the protection net is a protection net made of a flexible metal net, and the height of the protection net is greater than the height of the conservation reef group.
[0012] This can provide a more comprehensive protective effect.
[0013] Further preferably, the column is a cylindrical column, and the height of the column is greater than the height of the protective net.
[0014] Can ensure the fixation of the protection net.
[0015] Further preferably, a slide groove is provided in the center of the column, two fixing ropes are provided, and one end of the fixing rope is slidably connected to the column through a sliding block.
[0016] The protective position of the protection net can be adjusted by sliding the position of the fixing rope.
[0017] More preferably, the length of the fixing rope is 30-50 cm, so as to ensure the connection strength and leave a certain safety distance.
[0018] Further preferably, the plurality of nursery reefs are arranged in an L-shaped structure, so as to leave an aperture for the fry to move around, thereby preventing the internal space from being too narrow and being unfavorable for the fry to move around. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings.
[0022] Reference Figure 1 As shown, a multi-row tile-like nursery reef for larvae and juveniles with protective nets all around comprises a nursery reef group, a protective net 1 is arranged on the outside of the nursery reef group, the protective net is surrounded in a square structure, a column 2 is respectively arranged at the four corners of the protective net, and the column is connected to the corner of the protective net through a fixing rope 3; the nursery reef group comprises a plurality of nursery reefs 4, the nursery reef comprises a metal frame, a support rod is arranged on the back of the metal frame, one end of the support rod is fixed to the metal frame, and the other end of the support rod is inserted into the bottom layer, the metal frame is obliquely arranged in the protective net through the support rod, a plate body made of concrete is arranged inside the metal frame, the plate bodies are stacked up and down and arranged inside the metal frame, a partition is arranged between two adjacent plate bodies, the partition is fixedly connected to the metal frame, and the plate body has a tile-like structure.
[0023] The utility model can prevent the invasion of large fish from causing harm to the fry and juvenile fish in the conservation reefs by adding a protective net on the outer side of the conservation reef group. The metal frames arranged obliquely can better increase the contact area with the seawater, so that the surface of the board body is more likely to produce algae reproduction, providing natural nutrients for the fry and juvenile fish. The tile-shaped board body can facilitate the fry and juvenile fish to shuttle and forage, and can also play an effect of resisting enemies.
[0024] Further preferably, the protection net is made of a flexible metal net, and the height of the protection net is greater than the height of the conservation reef group, so as to achieve a more comprehensive protection effect.
[0025] More preferably, the column is a cylindrical column, and the height of the column is greater than the height of the protection net, so as to ensure the fixation of the protection net.
[0026] Preferably, a slide groove is provided in the center of the column, two fixing ropes are provided, and one end of the fixing rope is slidably connected to the column through a slider. The protective position of the protection net can be adjusted by sliding the position of the fixing rope.
[0027] Preferably, the length of the fixing rope is 30-50 cm, so as to ensure the connection strength and leave a certain safety distance.
[0028] Further preferably, the plurality of nursery reefs are arranged in an L-shaped structure, so as to leave an aperture for the fry to move around, thereby preventing the internal space from being too narrow and being unfavorable for the fry to move around.
