Description
Technical Field
The invention relates to an egg attaching device, in particular to a bottom-sinking type artificial cuttlefish egg attaching device.
Background
The cuttlefish needs to lay eggs on attachments, has high requirements on the attachments, and is generally selected to be firmer in fixation and smoother in surface. In the spawning site sea area, the gorgonia which is the main spawning attachment of the cuttlefish is not enough in quantity, the requirement of spawning of the parent cuttlefish can not be met, a plurality of fertilized eggs are attached to tender branch-shaped seaweeds, the fertilized eggs of the cuttlefish attached to the seaweeds are easy to fall off when encountering water flow impact, even the strings fall off, and once the fertilized eggs of the cuttlefish fall off, the fertilized eggs of the cuttlefish sink into the seabed sludge, the fertilized eggs of the cuttlefish are dead, the hatchability of the fertilized eggs of the cuttlefish is seriously reduced, and therefore, the repairing of the spawning attachment must be carried out synchronously while the proliferation and release work is strengthened. For this reason, a large number of artificial egg-laying bases are used to increase the attachment of cuttlefish eggs, but the inventors found in long-term work research that the current artificial egg-laying bases have the following disadvantages:
firstly, after the artificial egg-attaching base is put in the seabed, the cuttlefish can not lay eggs to provide an intimate egg-laying environment, and the cuttlefish can not go to lay eggs, so that the actual effect of the artificial egg-attaching base is poor.
Secondly, the number of eggs of each string of cuttlefish when laying eggs is extremely large, each string of eggs on the egg-attached base can reach more than 500, more eggs can even reach thousands of eggs, and the strings of cuttlefish eggs with extremely large number often can cause a large number of stacked cuttlefish eggs to lead to the growth retardation and even rotten death of a large number of cuttlefish eggs wrapped in the middle, so that the hatching rate is seriously reduced, and serious obstacles are caused to the propagation of cuttlefish resources in natural sea areas. In order to solve the problem, the inventor applies for Chinese patent publication No. CN110352881A on 5/2019, and the name of the invention is that the device for artificially inducing the cuttlefish to spawn is invented, and the application controls the number of eggs of each string of the cuttlefish by means of driving the parent cuttlefish by the baffle rod so as to avoid a large number of cuttlefish eggs from being stacked together, so that the parent cuttlefish in spawning is frightened and the spawning efficiency of the parent cuttlefish is influenced; moreover, the parent cuttlefish needs to continuously replace the spawning site (generally, the spawning amount of one parent cuttlefish reaches thousands), which affects the spawning efficiency of the parent cuttlefish; on the other hand, the number of eggs per string is also greatly reduced, so that the number demand of artificial egg-laying bases is sharply increased.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The first embodiment is as follows: as shown in fig. 1 and 2, a bottom-sinking type artificial cuttlefish egg attachment device comprises a support frame 1, a fish cage 3 and a plurality of egg attachment mechanisms 2. The supporting frame comprises a top frame 1.2, a bottom frame 1.1 and a side wall bracket 1.3 for connecting the top frame and the bottom frame. The support frame is sunk to the seabed and supported on the seabed through the underframe. The fish cage 3 is fixed on the supporting frame and used for trapping cuttlefish. In this embodiment, the fish cage is fixed in the middle of the upper surface of the bottom frame, and certainly, the fish cage can also be fixed on the top frame or the side wall bracket. The egg attaching mechanism 2 is arranged on the top frame and comprises a plurality of bionic eggs imitating the shape of cuttlefish eggs. In this embodiment, the egg attaching mechanisms are uniformly arranged and distributed.
On one hand, the embodiment utilizes the habit that the cuttlefish prefers to continue spawning on the spawned substrate to manufacture the bionic egg imitating the shape of the cuttlefish egg, provides an intimate spawning environment for the cuttlefish to spawn, induces the parent cuttlefish to enter the mesh cage through the access hole to spawn on the bionic egg, and improves the spawning efficiency of the parent cuttlefish; on the other hand, the cuttlefish is trapped by the fish cage, so that the cuttlefish can drill into the fish cage but cannot drill out, and after the cuttlefish enters the fish cage, the signal transmission function among the cuttlefish can be fully exerted, the staying time of the cuttlefish near the artificial egg-attached base is increased, and the oviposition chance of the cuttlefish is improved.
Further, as shown in fig. 1, a plurality of side baffles 1.4 are fixed on the side wall bracket, and a gap is formed between two adjacent side baffles, and the gap forms an entrance 1.5 for the cuttlefish to enter and exit. Therefore, a more concealed spawning place can be provided for the cuttlefish through the side baffles, so that the cuttlefish is induced to enter the passage gap to spawn by utilizing the concealment habit of the cuttlefish; and the impact of water flow on cuttlefish eggs attached to the egg attaching mechanism can be effectively reduced, so that the problem that the cuttlefish fertilized eggs are dead due to the fact that the cuttlefish eggs fall off and sink into seabed sludge in the hatching process is effectively solved.
Further, a trapping bag for trapping the cuttlefish is arranged in the fish cage, and bait is arranged in the trapping bag. So, can trap the cuttlefish through the bait in traping the bag, be favorable to the cuttlefish to get into the fish cage.
Further, as shown in fig. 1 and 2, a plurality of vertical guide sleeves 4 are arranged on the top frame 1.2. The egg attaching mechanisms correspond to the vertical guide sleeves one by one. The egg attaching mechanism further comprises a floating ball 2.1, a plurality of bionic eggs 2.2 imitating the shape of cuttlefish eggs, vertical guide rods 2.3 arranged in the corresponding vertical guide sleeves in a sliding manner, lower limiting blocks 2.7 arranged on the vertical guide rods, and a plurality of resistance sleeves 2.4 sequentially sleeved on the vertical guide rods from top to bottom. In this embodiment, the number of the resistance sleeves is 3, but may be 4 or 5 or more. The bionic eggs are hung on the corresponding vertical guide rods through connecting lines, and the bionic eggs are uniformly distributed on the vertical guide rods below the lower limiting block from top to bottom. The lower limiting block is positioned below the corresponding vertical guide sleeve. The floater is located the roof-rack top, and the floater is connected through second connection rope 2.6 with the upper end of vertical guide arm that corresponds. The vertical guide rod moves upwards under the buoyancy action of the floating ball, and the lower limiting block is abutted to the lower end of the corresponding vertical guide sleeve. The resistance sleeve is positioned above the corresponding vertical guide sleeve, and the resistance sleeve is positioned above the top frame. The maximum static friction force between the resistance sleeve and the vertical guide rod is f. When the vertical acting force acting on a certain resistance sleeve is larger than the maximum static friction force between the resistance sleeve and the vertical guide rod, the resistance sleeve slides along the vertical guide rod. Specifically, the buoyancy of the floating ball is larger than the gravity of the intermittent self-adjusting spawning mechanism. The difference between the buoyancy of the floating ball and the gravity of the intermittent self-adjusting spawning mechanism is F, the F value is 3-7N, and in the embodiment, the F value is 6N. The maximum static friction force between the resistance sleeve and the vertical guide rod is f and takes the value of 4-6N, and in the embodiment, the maximum static friction force between the resistance sleeve and the vertical guide rod is f and takes the value of 5N.
In the egg laying process of the parent cuttlefish, when the egg attaching amount on the bionic egg at a certain part of the parent cuttlefish egg attaching device reaches a set amount (when the gravity of the cuttlefish egg on the bionic egg at the part is more than 6N), the sum of the gravity of the cuttlefish egg on the bionic egg and the gravity of the intermittent egg laying self-adjusting mechanism is more than the buoyancy of the floating ball, and at the moment, the buoyancy of the floating ball is overcome, so that the vertical guide rod moves downwards along the vertical guide sleeve until the lowest resistance sleeve abuts against the upper end of the vertical guide sleeve; then, as the vertical guide rod moves downwards, the parent cuttlefish can lay eggs on the bionic egg at the other part of the egg attachment device, when the egg attachment amount of the parent cuttlefish on the bionic egg at the part reaches a set amount (when the gravity of the cuttlefish egg on the bionic egg at the part is more than 5N), the gravity of the cuttlefish egg overcomes the maximum static friction force between the lowest resistance sleeve and the vertical guide rod to be f, so that the vertical guide rod continuously moves downwards along the vertical guide sleeve until the middle resistance sleeve abuts against the upper end of the vertical guide sleeve; so, whenever the parent cuttlefish attaches the ovum volume when reaching the set value on the bionical ovum of a position, vertical guide arm will follow vertical guide pin bushing and continue to move the certain distance down, make parent cuttlefish will attach the oviposition on the bionical ovum of another position of ovum device, thereby avoid a large amount of cuttlefish eggs to pile up at a certain position, and lead to a large amount of cuttlefish eggs of being wrapped in the centre to develop the delay and rot death even, make the problem that the hatchability seriously reduces, and simultaneously, need not parent cuttlefish migration spawning position, can not disturb parent cuttlefish spawning yet, therefore can not influence parent cuttlefish's spawning efficiency. In addition, the egg attaching quantity of the egg attaching device cannot be influenced.
Further, as shown in fig. 2, the upper end of the vertical guide rod is provided with an upper limit block 2.5, and the resistance sleeve is positioned below the upper limit block.
Further, the resistance sleeves are distributed from top to bottom at equal intervals. The distance between two adjacent resistance sleeves is 10-20 cm.
