Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a megabalanus aquaculture and seeding collector in the sea. Background Art

[0002] Megabalanus belongs to Crustacea, Cirripedia, Sessilia, Balanidae, Megabalanus, and is also known as "horse teeth" or "oyster larvae". Most megabalanus inhabit the low-tide zone of the intertidal zone and shallow seas, attaching to the rocks by the sea or the bottom of ships.

[0003] The growth history of megabalanus is divided into two periods: the planktonic period and the sessile period. The planktonic period includes the following stages: the nauplius stage and a non-feeding cypris larva stage. The larvae in the nauplius stage feed on microalgae such as diatoms and have phototaxis. When the cypris larvae (abbreviated as cypris larvae) try to find a suitable substrate, they will secrete mucus to temporarily attach to the substrate and form footprints. They may continue to move until they find the most suitable attachment site. Then, after the cypris larvae find a suitable attachment point, they will secrete a highly viscous barnacle glue to firmly fix themselves on the surface of the substrate. Subsequently, they will undergo a series of complex physiological and morphological changes and finally form an adult form with a special conical shell.

[0004] At present, the culture of megabalanus has gradually become a potential aquaculture industry. Especially in some coastal countries and regions, megabalanus is regarded as a high-value seafood ingredient. Its meat is delicious and nutritious, containing high protein, low fat and various trace elements. In the process of artificial breeding of megabalanus, finding a suitable attachment substrate for the cypris larvae to attach is a crucial step. This not only relates to the healthy growth of megabalanus, but also directly affects the integrity and quality of megabalanus during harvesting. Megabalanus usually requires a hard and stable substrate to attach and grow. Therefore, selecting a suitable attachment substrate for megabalanus is the key to cultivation and a very important link in artificial breeding. During the process of harvesting megabalanus, it is very easy to cause shedding, cracking or even death due to mechanical force and other reasons, reducing the commercial value. The damaged and dead individuals are extremely easy to deteriorate and affect the edible value. How to provide an effective seeding device that can protect its growth and is easy to harvest intact individuals is an important problem that needs to be solved urgently. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the purpose of the utility model is to propose a megabalanus aquaculture and seeding collector in the sea to solve the problems mentioned in the above background art section.

[0006] The utility model is realized through the following technical solutions:

[0007] A giant barnacle marine aquaculture seeding collector, comprising a number of seeding collector units, each seeding collector unit including a counterweight core, with a rigid foam layer arranged around the counterweight core.

[0008] Furthermore, the rigid foam layer is completely submerged below the sea level, and the distance from the closest point of the rigid foam layer to the sea level fluctuates between 3 cm and 30 cm.

[0009] Furthermore, the counterweight core includes a connecting pipe, and a cement layer arranged on the outer periphery of the connecting pipe.

[0010] Furthermore, it also includes a connecting rope, which passes through the connecting pipe and is used to connect two of the seeding collector units.

[0011] Furthermore, the rigid foam layer is made of polystyrene.

[0012] Furthermore, the outer peripheral surface of the rigid foam layer is arranged in a concave-convex shape.

[0013] Furthermore, it also includes a counterweight block detachably connected to the counterweight core.

[0014] Furthermore, the counterweight core includes a core body and a core cover. The core body is provided with a groove, the core cover is used to seal the opening of the groove, and the counterweight block is arranged in the groove.

[0015] The beneficial effect of the present utility model is as follows: A giant barnacle marine aquaculture seeding collector, comprising a number of seeding collector units, each seeding collector unit including a counterweight core, with a rigid foam layer arranged around the counterweight core. By using the rigid foam layer as the attachment substrate for Venus larvae, the hardness and strength of the rigid foam layer itself enable Venus larvae to be willing to attach and grow on the rigid foam layer and finally grow into giant barnacles. During the process of harvesting giant barnacles, the giant barnacles together with the rigid foam layer can be cut, and then the rigid foam layer can be cleaned later, which can avoid the giant barnacles from cracking or even dying during the process of harvesting giant barnacles.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It should be noted here that the descriptions of these embodiments are used to help understand the present utility model, but do not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Referring to Figures 1 to 5 As shown, a sea-culturing seedling collector for giant barnacles includes a plurality of single seedling collectors 1. Each single seedling collector 1 includes a counterweight core 11, and a rigid foam layer 12 is arranged on the outer periphery of the counterweight core 11. By using the rigid foam layer 12 as the attachment substrate for Venus larvae, the hardness and strength of the rigid foam layer 12 itself enable Venus larvae to be willing to attach and grow on the rigid foam layer 12 and finally grow into giant barnacles. During the harvesting process of the giant barnacles, the giant barnacles can be cut together with the rigid foam layer 12, and then the rigid foam layer 12 can be cleaned later, which can avoid the rupture or even death of the giant barnacles during the harvesting process. The large buoyancy of the rigid foam layer 12 enables the single seedling collector 1 to remain stable on the water surface.

[0025] Utilizing the characteristic that the larvae in the nauplius stage have phototaxis, the rigid foam layer 12 is completely immersed below the sea level, and the distance from the nearest point of the rigid foam layer 12 to the sea level fluctuates between 3 cm and 30 cm. This enables the larvae in the nauplius stage in the ocean to grow into larvae in the Venus larva stage to attach to the rigid foam layer 12 as soon as possible, improving the breeding efficiency of the seedling collector of the present utility model.

[0026] The counterweight core 11 includes a connecting pipe 112 and a cement layer 111 attached to the outer periphery of the connecting pipe 112 by pouring. Using cement as the counterweight material makes the manufacturing cost of the entire single seedling collector 1 low. And it enables the rigid foam layer 12 to be completely immersed below the sea level.

[0027] It also includes a connecting rope 2 which passes through the connecting pipe 112. The connecting rope 2 is used to connect two single seeding devices 1. By using the connecting rope 2 to connect several single seeding devices 1 in series, a stable and flexible floating platform is formed, which is convenient for batch artificial breeding of Balanus amphitrite.

[0028] The rigid foam layer 12 is made of polystyrene. The rigid foam layer 12 made of polystyrene has a low price, making the price of the whole single seeding device 1 low.

[0029] The outer peripheral surface of the rigid foam layer 12 is arranged in a concave-convex shape, increasing the contact area between the rigid foam layer 12 and seawater, improving the attachment area of Balanus amphitrite, enabling the single seeding device 1 to attach more Balanus amphitrite, and improving productivity. The concave-convex structure can refer to Figure 4 the conical concave-convex shape, and in another embodiment, the concave-convex structure can refer to Figure 5 the arc-shaped concave-convex shape shown.

[0030] It also includes a counterweight block 115 detachably connected to the counterweight core 11. By increasing or decreasing the number of counterweight blocks 115, the depth at which the single seeding device 1 sinks into the sea level can be adjusted, so as to sink the single seeding device 1 to the approximate living depth of Balanus amphitrite.

[0031] The counterweight core 11 includes a core body 113 and a core cover 114. The core body 113 is provided with a groove, and the core cover 114 is used to block the opening of the groove. The counterweight block 115 is arranged in the groove. Among them, the core body 113 and the core cover 114 can be connected by a threaded connection method, which is convenient for increasing or decreasing the counterweight block 115. The groove is preferably arranged in a ring shape, and the counterweight block 115 is a ring sleeved in the groove. The core body 113 can be manufactured by filling plastic shells with cement.

[0032] In other embodiments, the core body 113 and the core cover 114 can be connected by a way of hinging at one end and buckling at the other end.

[0033] In other embodiments, the counterweight block 115 can be connected to the counterweight core 11 by a bundling method. In this embodiment, the counterweight core 11 does not have a groove, and the counterweight core 11 is integrally formed by casting.
