Description

Technical Field

[0001] The invention relates to the technical field of artificial fish reefs, and in particular to a squid reef integrating spawning and raising squid. Background Art

[0002] Since the 1970s, the development of squid resources has been increasing. High-intensity fishing and unreasonable fishing methods have caused large fluctuations in resources, especially bottom trawling operations have caused serious damage to squid spawning habitats. The resources of the needleless squid have declined significantly and have not recovered since then. The fertilized eggs of squid are sticky eggs, and they prefer to lay their eggs on the substrate. Suitable attachment reefs can help increase the number of eggs laid by squid parents and the hatching rate of fertilized eggs. The replenishment and recovery of the number of squid resources in natural sea areas mainly depends on the amount of eggs laid and the hatching rate and survival rate of the larvae. At present, the research on squid spawning attachment reefs focuses on the squid's selection preference for attachment reefs and the effect of egg attachment, but there is little research on the types, functions and applications of squid attachment reefs, and there is a lack of research on the suitability of attachment reefs for larvae to live and rear.

[0011] Specifically, the attachment material is a bundle of bamboo filaments.

[0012] One or more technical solutions provided in the present invention have at least the following technical effects or advantages:

[0013] 1. The floating fish reef is located above the bottom-mounted attachment reef; the floating body is arranged on the upper frame; the light-shielding clay board is arranged in the middle of the upper frame; holes of different sizes are provided on the light-shielding clay board; the upper netting is arranged on the side of the upper frame; the clay pipe is arranged on the upper netting; holes of different sizes are provided on the clay pipe; the attachment rope is horizontally connected to the inner side of the upper frame; the clay box is hung on the attachment rope; holes of different sizes are provided on the clay box; the pile rope connects the upper frame and the pile; the lower netting is arranged outside the lower frame, and an entrance and exit are provided on the lower netting; the fixing rope is arranged in the lower frame, and attachment materials are provided on the fixing rope; the upper end of the bracket is connected to the lower frame, the lower end of the bracket is connected to the floor footing, and the upward-facing surface of the floor footing is of a concave structure.

DETAILED DESCRIPTION

[0025] The embodiment of the present invention provides a squid reef that integrates spawning and rearing, combines floating fish reefs and bottom-mounted spawning and attachment reefs, opens up the complete process of spawning-hatching-rearing, provides a continuous habitat for squid, and is of great significance for the restoration of squid resources.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the cuttlefish reef integrating egg-laying and juvenile rearing provided by the embodiment of the present invention includes: a floating fish reef 1 and a bottom-mounted attachment reef 2; the floating fish reef 1 is located above the bottom-mounted attachment reef 2; the floating fish reef 1 includes: an upper frame 105, a floating body 101, a light-shielding clay board 102, an upper netting 106, a clay pipe 107, an attachment rope 103, a clay box 108, a pile rope 110 and a pile 111; the floating body 101 is arranged on the upper frame 105 to provide buoyancy for the fish reef, so that the fish reef floats on the sea surface; the light-shielding clay board 102 is arranged in the middle of the upper frame 105; holes of different sizes are provided on the light-shielding clay board 102, which can block strong light and attach seaweeds; the upper netting 106 is arranged on the side of the upper frame 105; the clay pipe 107 is arranged on the upper netting 106; holes of different sizes are provided on the clay pipe 107 for algae to attach and grow, and for cuttlefish to avoid enemies and inhabit; the attachment rope 103 is horizontally connected to the inner side of the upper frame 105; the clay box 108 is hung on the attachment rope 103; holes of different sizes are provided on the clay box 108 to provide a habitat for cuttlefish; the pile rope 110 connects the upper frame 105 and the pile 111; the bottom-mounted attachment reef 2 includes: a lower frame 201, a lower netting 203, a fixing rope 209, a bracket and a foundation 206; the lower netting 203 is arranged outside the lower frame 201, and an entrance and exit are provided on the lower netting 203; the fixing rope 209 is arranged in the lower frame 201, and an attachment material 208 is provided on the fixing rope 209; the upper end of the bracket is connected to the lower frame 201, the lower end of the bracket is connected to the foundation 206, and the upward-facing surface of the foundation 206 is a concave structure.

[0028] Specifically, the attachment material 208 is a bundle of bamboo filaments. The material of the upper frame 105 is bamboo, which can fix the shape and provide partial buoyancy support; the attachment ropes 103 are horizontally connected at the same spacing, so that they are evenly distributed horizontally on the bottom surface of the fish reef, and large seaweeds 104 are arranged on the attachment ropes 103 to facilitate the formation of a seaweed field; the upper netting 106 and the attachment ropes 103 provide an attachment base for the large seaweeds 104. The large seaweeds 104 will absorb a large amount of nutrients in the upper water body and continuously provide new productivity to provide bait for juvenile cuttlefish. The attachment ropes 103 are nylon ropes, hemp ropes or polyethylene ropes, which are suitable for the attachment of large seaweeds 104; the foundation 206 is welded by angle steel, with a sharp bottom for easy penetration into the ground. The upward-facing surface is a concave structure, which has a large stress area with the sediment and is not easy to be pulled out, preventing overturning. The pile 111 includes four-corner fixed piles and vertical fixed piles to maintain the position and shape of the fish reef and enhance the stability of the floating fish reef 1. The material of the lower frame 201 is stainless steel to ensure the anti-impact ability of the reef body and ensure that the weight of the reef body is appropriate; the lower netting 203 can play a role in protecting cuttlefish parents and cuttlefish eggs, and has a small effect on blocking the water flow; the round entrance and exit 207 is just the right size for cuttlefish to pass through, preventing other large fish from entering. Using the habit of cuttlefish loving to drill holes, it can play a role in attracting cuttlefish.

[0029] Specific description of the light-shielding clay board 102 is as follows: Figure 5 As shown in the figure, the size of the light-shielding clay board 102 is length × width = 1m × 1m, with a thickness of 2 cm, a light transmittance of ≥ 50%, and there are relatively large clay board light-transmitting holes 112 and small clay board holes 113 convenient for algae attachment, which can avoid strong light irradiation and is beneficial for cuttlefish to inhabit. Each light-shielding clay board is connected to each other by a nylon rope every 30 cm, and the four sides are fixed to the upper frame 105. In the case of poor light conditions such as in winter, the number of light-shielding clay boards 102 can be reduced.

[0030] Specific description of the clay pipe 107 is as follows: Figure 6 As shown in the figure, the diameter of the clay pipe 107 is 10 - 15 cm, the length is 1 m, the wall thickness is 1.5 - 2 cm, the diameter of the clay pipe inlet and outlet 116 is 3 - 5 cm (for juvenile cuttlefish to enter and exit), the diameter of the small clay pipe holes 115 is 0.5 - 1 cm (to promote algae attachment), the openings are arranged in a spiral along the pipe body, the hole spacing is 10 - 15 cm, and the inner wall of the hole mouth is polished smoothly to avoid scratching the juveniles. A baffle 114 is set to prevent larger fish from entering. Each clay pipe 107 is horizontally tied to the vertical grid lines of the upper netting 106 with a nylon rope every 30 cm to form a "netting - clay pipe" composite structure.

[0031] Specific description of the clay box 108 is as follows: Figure 7 As shown in the figure, the size of the clay box 108 is 50 cm × 50 cm × 10 cm, and it contains 4 chambers inside. The diameter of the clay box inlet and outlet 118 is 3 - 5 cm for juvenile cuttlefish to enter and exit, and the diameter of the small clay box holes 117 is 0.5 - 1 cm to promote algae attachment and provide a sheltered environment. Juvenile cuttlefish tend to hide from natural enemies in low-light areas, so as to attract juvenile cuttlefish to gather and inhabit. The clay box 108 is suspended 30 cm below the attachment rope 103 by a rope, and one clay box is placed every 2 meters.

[0032] In order to attract and guide cuttlefish into the floating fish reef 1, the floating fish reef 1 further includes: a luminous guiding rope 109; the luminous guiding rope 109 is hung on the upper frame 105.

[0033] Specific description of the luminous guiding rope 109: The luminous guiding rope 109 is made by combining fluorescent materials with high-strength fibers, and the outer layer is coated with a silica gel protective layer to enhance the tensile strength and wear resistance. Rare earth aluminate is environmentally friendly and non-toxic, without the need for dyeing. After absorbing light for 10 minutes, it can continuously emit light for 8 - 12 hours, is wash-resistant and has a long lifespan. The fluorescent color preferably selects 470 nm blue light to adapt to the phototaxis requirements of Sepiella maindroni, so as to attract and guide cuttlefish. The luminous guiding rope 109 extends to the seaweed clay breeding area to form a "light channel".

[0034] In this embodiment, the high-strength fiber is nylon or polyethylene.

[0035] In order to increase the algae attachment rate and the approach of squid larvae, the shading clay plate 102, clay tube 107, and clay box 108 are all made of crushed shells, which are mixed with clay raw materials at a ratio of 10%-15%. After sintering, a calcium-rich surface microporous structure is formed, simulating the composition of natural reefs, and having both buoyancy and ecological functions.

[0036] In order to form a biophilic film and accelerate the colonization of algae spores, polysaccharide substances are sprayed on the surface of the microporous structure.

[0037] In order to increase the anti-sinking effect of the embodiment of the present invention, Figure 8 As shown, the bottom-mounted attachment reef 2 also includes: an anti-sinking body 204 and a latch 210; a concave structure 205 is provided at the bottom of the anti-sinking body 204; a longitudinal through hole is provided at the center of the anti-sinking body 204, and a transverse through hole is provided at the side of the anti-sinking body 204; there are also transverse through holes on the bracket; the bracket passes through the longitudinal through hole; the latch 210 is inserted into the transverse through holes on the anti-sinking body 204 and the bracket in sequence. When the fish reef sinks to this position, the resistance increases due to the influence of the concave structure 205, which will prevent the fish reef from continuing to sink downward, thereby achieving an anti-sinking effect.

[0038] When deploying the embodiment of the present invention, firstly, bottom-mounted spawning attachment reefs are deployed in a predetermined sea area, and the reef groups are reasonably arranged at the same spacing; piling is carried out in the deployment sea area; then, large seaweed 104 is transplanted on the attachment rope 103, and then the floating fish reef 1 is deployed to the predetermined sea surface, and the pile 111 is connected with one end of the pile rope 110, and the other end is connected to the four corners of the floating fish reef 1, and the length of the pile rope 110 is set according to the sea water depth and actual needs.

[0039] In summary, the embodiments of the present invention provide an integrated reef composed of a squid spawning attachment reef and a floating fish reef for raising young on a muddy bottom. The integrated reef can be overturned in a muddy bottom sea area to provide a stable attachment base for squid spawning, and to construct a floating fish reef seaweed field in the upper sea area to provide an ideal ecological environment for juvenile squid. The synergistic linkage effect of the floating fish reef and the bottom-mounted spawning attachment reef is brought into play, thereby improving the comprehensive utilization efficiency of marine resources, opening up the complete process of spawning-hatching-raising, providing a continuous habitat for squid, and accelerating the restoration of squid resources.
