Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, and in particular to a device for observing the reproductive behavior of the needleless squid. Background Technology

[0002] Currently, single-box observation structures are commonly used to observe the reproductive behavior of Cuttlefish mansoni. However, in practical applications, these structures suffer from insufficient guidance for the species' breeding zone, are not adapted to its habits, and have difficulty obtaining information on reproductive behaviors. Therefore, they cannot meet higher testing requirements and need to be improved. Utility Model Content

[0003] This invention provides a device for observing the reproductive behavior of *Sepia mansoni* with clearly defined functional zones, significantly reduced observation interference, simultaneous observation of the attraction of different substances to *Sepia mansoni*, stable structure, and easy operation, which can meet higher testing requirements. It solves the technical problems of existing testing devices, such as simple structure, many interfering factors, poor controllability, insufficient guidance for the species' breeding area, failure to adapt to its habits, difficulty in obtaining reproductive-related behavioral information, and inability to meet higher testing requirements.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: a device for observing the reproductive behavior of Cuttlefish Mansoni, comprising an observation box, wherein the observation box is formed by an outer box panel and an inner box panel, the outer box panel and the inner box panel dividing the observation box into two areas: an inner central activity area and an outer peripheral observation area. Four outer partitions are connected at the four corners between the outer box panel and the inner box panel, and the partitions divide the peripheral observation area into multiple independent areas. Several feeding pools are provided around the observation box, and an adjustment component for controlling the passage of cuttlefish is provided on the inner box panel. The observation box of this invention is divided into two core areas by the action of the outer and inner box panels. The central activity area is used to release *Sepia mandshurica*. Before observation, different substances adapted to the habits of *Sepia mandshurica* are placed in each feeding pool, such as *Sepia mandshurica* of different sexes, different baits, different spawning attachments, different odor attractants, and so on, to test the conditions. Under the attraction of different substances, *Sepia mandshurica* will pass through the adjustment components and enter different peripheral observation areas. The attraction situation can be judged according to the number of *Sepia mandshurica* in each peripheral observation area, thereby testing various habits of *Sepia mandshurica*.

[0005] Preferably, the bait pool has a hemispherical shell structure, which is integrally formed or glued to the outside of the outer casing. The top and inner side of the bait pool are open, and the outer casing has an interface for connecting the bait pool. The hemispherical structure is easy to manufacture and clean, and the open design of the top and inner side facilitates feeding and observation of squid feeding behavior, while ensuring that the bait scent can effectively diffuse to the surrounding observation area to attract squid.

[0006] Preferably, a removable fine mesh partition is provided between the bait pool and the outer casing. The fine mesh partition ensures that the bait material in the bait pool diffuses to the surrounding observation area, while preventing the needleless squid from entering the bait pool.

[0007] Preferably, the inner side of the outer casing plate is provided with a U-shaped slot plate, and the fine mesh partition is inserted into the outer casing plate from top to bottom along the slot plate. The slot plate provides a stable and reliable installation structure, ensuring that the fine mesh partition is fixed in position and has good sealing after installation, preventing bait from leaking from the edges; the U-shaped design makes disassembly and assembly operations simple and quick, improving the efficiency of experimental preparation.

[0008] Preferably, the adjustment component includes a mounting base fixed to the inner casing plate. A turntable is rotatably mounted on the mounting base via a central shaft and bearings. The turntable has several through holes of different diameters to control the passage of squid of different sizes. The turntable structure is simple, reliable, and intuitive to operate. By rotating the turntable, the through holes of different diameters can be easily and quickly aligned, thereby precisely controlling the minimum size of squid allowed to pass through, adapting to the needs of different growth stages of squid or selective observation of specific individuals.

[0009] Preferably, the inner housing plate has housing holes corresponding to the through holes on the turntable. These housing holes serve as fixed access points, engaging with the movable through holes on the turntable to ensure that the passageways connecting the two areas maintain structural alignment regardless of how the turntable rotates.

[0010] Preferably, the adjustment assembly further includes positioning holes respectively formed on the inner casing plate and the turntable; the number of positioning holes on the turntable corresponds to the number of through holes, and when any through hole is aligned with a hole in the casing, at least one set of positioning holes on the turntable is also aligned with positioning holes on the inner casing plate; the turntable is provided with positioning pins that can be inserted through the positioning holes on the turntable and the inner casing plate. The positioning pin and positioning hole structure is used to lock the turntable, preventing the turntable from rotating due to the squid's movement during the test, thus affecting the observation results.

[0011] Preferably, the adjustment assembly further includes a constraint plate fixed to the inner housing plate. The constraint plate has an L-shaped structure and is fixed to the bottom edge of the turntable. The constraint plate can prevent the turntable from warping while ensuring normal rotation, thus ensuring stable operation of the turntable.

[0012] Therefore, the device for observing the reproductive behavior of the Japanese spiny squid of this invention has the following advantages: clear functional division, which can significantly reduce observation interference, can simultaneously observe the attraction of different substances to the Japanese spiny squid, stable structure, easy to operate, and can meet higher testing requirements.

Detailed Implementation

[0019] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] Example: like Figure 1 and 2 As shown in Figures 3, 4, and 5, an apparatus for observing the reproductive behavior of the Japanese spiny squid includes an observation box consisting of an outer box plate 1 and an inner box plate 2; the outer box plate 1 and the inner box plate 2 divide the observation box into two areas: an inner central activity area 3 and an outer peripheral observation area 4.

[0021] Four outer partitions 5 are connected at the four corners between the outer box panel 1 and the inner box panel 2, and the four outer partitions 5 divide the outer observation area 4 into four independent areas.

[0022] Four bait pools 6 are installed around the outer side of the observation box. The bait pools 6 have a hemispherical structure and are either integrally molded or glued to the outside of the outer box panel 1.

[0023] The top and inner side of the bait pool 6 are open structures, and the outer box plate 1 has a connection interface that communicates with the bait pool 6, so that the bait pool 6 is connected to the inner space of the outer box plate 1.

[0024] Each joint of the outer casing plate 1 is equipped with a removable fine mesh partition 7; a U-shaped slot plate 8 is fixedly installed on the inner side of the outer casing plate 1, and the fine mesh partition 7 is inserted into the outer casing plate 1 from top to bottom along the U-shaped groove of the slot plate 8.

[0025] An adjustment assembly for controlling the passage of squid is installed on the inner box plate 2; the adjustment assembly includes four mounting seats 9 installed on the inner box plate 2, and a turntable 11 is rotatably mounted on each mounting seat 9 via a central shaft 10, bearings, washers, and bolts.

[0026] Each turntable 11 has four through holes 12 of different diameters, and the inner box plate 2 has box holes corresponding to the through holes 12 on the turntable 11; the diameter of the box holes is larger than the diameter of the largest through hole 12 on the turntable 11.

[0027] The adjustment assembly also includes positioning holes 13 on the inner housing plate 2 and the turntable 11. Each inner housing plate 2 has one positioning hole 13, and each turntable 11 has four positioning holes 13. The number of positioning holes 13 on the turntable 11 corresponds to the number of through holes 12. When any through hole 12 is aligned with a housing hole, at least one set of positioning holes 13 on the turntable 11 is also aligned with the positioning holes 13 on the inner housing plate 2. A positioning pin 14 is installed on the turntable 11 that can be inserted through the positioning holes 13 on the turntable 11 and the inner housing plate 2.

[0028] The adjustment assembly also includes a constraint plate 15 fixed on the inner box plate 2. The constraint plate 15 has an L-shaped structure and is fixed at the bottom edge of the turntable 11.

[0029] Before the observation, different substances adapted to the habits of the Japanese needleless squid were placed in each baiting pond 6, such as Japanese needleless squid of different sexes, different baits, different spawning attachments, different odor attractants, and so on, to test the conditions.

[0030] Artificial seawater was then injected into the observation tank, and environmental parameters such as temperature, light, and salinity were adjusted.

[0031] Then place a similarly sized needleless squid in the central activity area 3; rotate the turntable 11 to align the through hole 12, which is suitable for the size of the needleless squid, with the hole in the box, and lock it in place by inserting the positioning pin 14 into the positioning hole 13.

[0032] The attraction of different substances in the bait pool 6 to the needleless squid can be observed. Under the attraction of different substances in the bait pool 6, the needleless squid will pass through the through hole 12 and enter different peripheral observation areas 4. The attraction situation can be judged according to the number of needleless squid in each peripheral observation area 4, and then the various habits of the needleless squid can be tested.

[0033] The specific embodiments described herein are merely illustrative examples of the present invention.
