[0002] Porphyra haitanensis is one of the two main species of artificially cultivated Porphyra in my country. It is rich in nutrition and delicious. The traditional method of collecting seedlings of Porphyra haitanensis conchospores is to release the conchospores and collect seedlings in a pool or a specific container after the conchospores are ripened and stimulated. The present invention is to improve the quality of seedlings by improving and innovating on the basis of the traditional seedling collection method. Summary of the invention

[0003] The invention aims to overcome the deficiencies of the prior art and provide a method for collecting conchospore seedlings of Porphyra haitanensis at sea, so as to improve the seedling quality by providing better offshore conditions for seedling cultivation.

[0004] The present invention adopts the following technical scheme: a method for collecting conchospores of Porphyra haitanensis, comprising the following steps:

[0005] [1] Pack the shell filaments into net bags, tie the net bags and hang them on both sides of the boat to stimulate water flow;

[0006] [2] Move the mesh bag stimulated by running water to a reservoir filled with seawater;

[0007] [3] Shake the net bag upside down in the water reservoir to promote the release of conchospores;

[0008] [4] After the conchospores are released, the net bag is removed and the net curtain to be used for seedling collection is placed in a reservoir containing a large number of conchospores for dipping;

[0009] [5] Stack the net curtains with collected seedlings into 8-10 pieces and hang them in the sea area.

[0010] As an improvement, step [1] also includes: selecting 14:00 on the day to 6:00 on the next day for water flow stimulation.

[0011] As an improvement, step [1] also includes: driving the boat to an area with deep and smooth water in advance, where the water temperature is 25-30°C, and parking downstream.

[0012] As an improvement, step [2] further includes: before the net bag is moved to the reservoir, washing away dirt on the surface of the net bag with seawater.

[0013] As an improvement, step [3] further includes: shaking the net bag upside down several times every 30 minutes until noon.

[0014] As an improvement, step [4] also includes: the net curtain is continuously stirred up and down to mix during the dyeing process.

[0015] As an improvement, between step [4] and step [5], the method further includes: step [4.1] pressing the net bag onto the net curtain and continuing to shake it up and down to promote the subsequent release and attachment of the shell spores.

[0016] As an improvement, the method further includes the following between step [4.1] and step [5]: step [4.2] after observing under a microscope at 100 times magnification that more than 10 conchospores are attached to the net curtain, the boat is driven to a temporary rearing area for temporary rearing of the seedling curtain.

[0017] As an improvement, the water tank is arranged in the cabin through a ship-borne bracket mechanism, the ship-borne bracket mechanism includes a canvas bag body with a cubic space, a plurality of support rods and a plurality of placement pieces, and ears for the support rods to pass through are arranged at intervals on the two long sides of the upper opening of the canvas bag body, and the head and tail ends of the support rods have threaded sections that can be spirally disassembled and assembled, so that the plurality of support rods are connected head to tail, and the placement pieces are arranged in pairs on the side of the ship on both sides, and two long rods formed by the head and tail connection of the plurality of support rods pass through the ear pairs on the two long sides of the canvas bag body to suspend the canvas bag body, and the two ends of the two long rods are placed on the placement pieces on the side of the ship on both sides for limiting, and heavy objects are hung at the four bottom corners of the canvas bag body to limit the shape of the canvas bag body.

[0018] As an improvement, the placement piece includes a base, a support portion and a side stop portion. The base is made of a non-deformable material and is installed on the side of the ship through fasteners. The support portion is made of a deformable material and has both ends installed on the base. A space is reserved at the base position corresponding to the middle of the support portion for the middle of the support portion to deform downward. The side stop portion is made of a non-deformable material and is divided into two groups that are symmetrically arranged upward on the support portion. There is a placement space for the long rod between the two groups of side stops. When the long rod is placed in the placement space, its weight causes the support portion to deform downward. The two groups of side stops swing toward each other depending on the deformation of the support portion and form a limit for the upper part of the long rod.

[0019] The invention has the beneficial effects of promoting the growth of conchospore seedlings by fully stimulating the conchospores with flowing water at sea, and releasing the conchospores and impregnating the net curtains under the same seawater conditions at sea, thereby ensuring the quality of seedling collection and seedling cultivation.

[0024] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , 2 , 3 and 4 are specific embodiments of the method for collecting conchospores of Porphyra haitanensis and the ship-borne support mechanism used therein of the present invention.

[0026] A method for collecting conchospore seedlings of Porphyra haitanensis comprises the following steps:

[0027] [1] Drive the boat to an area with deep and flowing water in advance, with a water temperature of 25-30°C, and park it downstream. Pack the shell filaments into net bags, tie the net bags and hang them on both sides of the boat. Choose between 14:00 on the same day and 6:00 the next day to stimulate the flow of water;

[0028] [2] Rinse the mesh bags stimulated by running water with seawater to remove dirt from the surface of the mesh bags, and move them to a reservoir filled with seawater;

[0029] [3] Shake the net bag upside down in the water reservoir several times every 30 minutes until noon to promote the release of conchospores;

[0030] [4] After the conchospores are released, the net bag is removed and the net curtain to be used for seedling collection is placed in a reservoir containing a large amount of conchospores for immersion. The net curtain is continuously stirred up and down to mix well during immersion.

[0031] [4.1] Press the net bag onto the net curtain and continue to shake it up and down to promote the subsequent release and attachment of conchospores;

[0032] [4.2] After observing under a microscope at 100 times magnification that there are more than 10 conchospores attached to the net curtain, the boat is moved to the temporary rearing area for seedling curtain temporary rearing;

[0033] [5] Stack the net curtains with collected seedlings into 8-10 pieces and hang them in the sea area.

[0034] When the present invention is implemented, an area with deep and smooth water is selected, that is, a ship is driven to a sea area that meets the conditions in advance, and the seedling collection operation of the above steps is carried out at sea; a location with a water temperature of 25-30°C is selected for parking downstream, and a time period from 14:00 on the same day to 6:00 on the next day is selected, and water flow stimulation is performed on the shell filaments in the net bag during high tide, so as to achieve a better stimulation effect and promote the growth of shell spore seedlings.

[0035] At a certain time the next day, the stimulated shell filaments will be moved to the deck of the ship, and the dirt on the surface of the net bag will be rinsed off with seawater using a water pipe to ensure the cleanliness of the subsequent water reservoir environment. The net bags containing the rinsed shell filaments will be evenly placed in the temporary water reservoir on the ship. The shells in the net bags will be turned upside down several times every 30 minutes to promote the release of shell spores.

[0036] The process of releasing the shell spores lasts until noon, that is, the process takes approximately 6:00-12:00, and then the net bag is removed, and the net curtain prepared for collecting seedlings is placed in a reservoir containing a large amount of shell spores for immersion. In order to achieve better results in the immersion process, the net curtain is constantly stirred and mixed up and down during immersion; during the entire immersion process, the net bag is pressed onto the net curtain, and continues to be shaken up and down to promote the subsequent release and attachment of shell spores in the net bag, thereby further improving the quality of immersion and attachment.

[0037] At the end of the infiltration, the conchospores attached to the net curtain are observed under a microscope at 100 times magnification. When the requirements are met, that is, more than 10 conchospores are attached to the net curtain, the infiltration process is completed and the boat is driven to the temporary breeding area for seedling curtains. The net curtains returned to the temporary breeding area are stacked by fishermen in 8-10 sheets and hung in the sea area, completing the entire seedling collection process.

[0038] The invention promotes the growth of conchospore seedlings by fully stimulating the conchospores with flowing water at sea, releases the conchospores and impregnates the net curtains while maintaining the same seawater conditions at sea, thereby ensuring the quality of seedling collection and seedling cultivation.

[0039] As an improved specific implementation method, the water tank is set in the cabin through a ship-borne bracket mechanism 1, and the ship-borne bracket mechanism 1 includes a canvas bag body 11 with a cubic space, a plurality of support rods 12 and a plurality of placement pieces 13. The two long sides of the upper opening of the canvas bag body 11 are spaced apart with hanging ears 111 for the support rods 12 to pass through, and the head and tail ends of the support rods 12 have threaded sections 121 that can be spirally disassembled, so that the plurality of support rods 12 are connected head to tail, and the placement pieces 13 are arranged in pairs on the side of the ship on both sides, and two long rods formed by the head and tail connection of the plurality of support rods 12 pass through the hanging ears 111 on the two long sides of the canvas bag body 11 to suspend the canvas bag body 11, and the two ends of the two long rods are placed on the placement pieces 13 on the side of the ship on both sides for limiting, and heavy objects 112 are hung at the four corners of the bottom of the canvas bag body 11 to limit the shape of the canvas bag body 11.

[0040] like Figure 1 , 2As shown, because the main seedling collection process is completed at sea, the temporary water storage tank needs to meet the layout conditions required on the ship, and the structure needs to be easy to disassemble and assemble, so that fishermen can quickly arrange and disassemble, and cannot rigidly occupy the space of the ship, so that the ship can be used for other marine operations. The ship-borne bracket mechanism 1 designed for the seedling collection method has a canvas bag body 11, the size of the canvas bag body 11 is customized according to the width of the ship, and multiple canvas bags 11 are arranged along the length direction of the ship to form multiple cubic spaces as independent water storage tanks. The length of a single support rod 12 is effectively controlled, and several support rods 12 are docked according to the width of the ship. The docking is carried out by screwing the threaded sections 121 at both ends. The length of the formed long rod is based on the ability to reach the ship's side on both sides. When docking, several support rods 12 can be pre-pierced through the lugs 111 at the location, and then inserted into several lugs 111 after being docked into a whole long rod. Two long rods can support a canvas bag body 11, and the long sides of adjacent canvas bag bodies 11 can be inserted into the same long rod through the lugs 111, so that the adjacent canvas bag bodies 11 are arranged closely. The placement pieces 13 are pre-installed on the sides of the ship, and the two ends of the long pole are placed on the placement pieces 13 on the sides of the ship for positioning. After the seawater is injected into the canvas bag body 11, the overall weight increases, which can improve the stability of the placement of the two ends of the long pole; and in order to improve the structural stability of the canvas bag body 11, heavy objects 112 are hung at the four corners of the bottom of the canvas bag body 11 to limit the shape of the canvas bag body 11 and keep the canvas bag body 11 in a good unfolding state; as a whole, the overall structure of the canvas bag body 11 will not be affected when the ship is moving in the sea or the waves are bumpy. After use, the heavy objects 112 are removed and the seawater in the canvas bag body 11 is drained, and the long pole can be easily removed and separated into shorter support rods 12, which can be stored in a smaller volume as a whole, do not occupy the ship space, and are easy to use.

[0041] As an improved specific implementation method, the placement member 13 includes a base 131, a support portion 132 and a side stop portion 133. The base 131 is made of a non-deformable material and is installed on the side of the ship through fasteners. The support portion 132 is made of a deformable material and has both ends installed on the base 131. The position of the base 131 corresponding to the middle part of the support portion 132 reserves a space for the middle part of the support portion 132 to deform downward. The side stop portions 133 are made of a non-deformable material and are two groups symmetrically arranged upward on the support portion 132. There is a placement space for a long rod between the two groups of side stops 133. When the long rod is placed in the placement space, its weight causes the support portion 132 to deform downward. The two groups of side stops 133 swing toward each other depending on the deformation of the support portion 132 and form a limit on the upper part of the long rod.

[0042] like Figure 3 , 4As shown, when designing the placement member 13, on the one hand, the bumpy environment on the ship itself is taken into consideration, and on the other hand, the need for easy disassembly and assembly is taken into consideration. First, a base 131 is made of a non-deformable material, which is fixed to the side of the ship by fasteners to form a stable long pole placement position; then a support portion 132 is made of a deformable material, and the support portion 13 cooperates with the side blocking portions 133 on both sides to form a space structure that is open at the top and penetrates from front to back, in which the long pole can be directly placed from above, and the length of the long pole does not affect its placement; after the long pole is placed and seawater is injected into the canvas bag body 11, the overall weight will be greatly increased, which will then press down the support portion 132 to deform it, and the side blocking portions 133 on both sides will tilt toward each other due to the deformation of the support portion 132, and then contact the upper part of the long pole to form a limit, and the long pole will not fall out of the limit structure, thereby achieving the effect of limit fixing, and when disassembly is required, releasing the seawater in the canvas bag body 11 can directly remove the most important factor, and the long pole can be easily released from the limit state and extracted upward, which is convenient for use. When the ship is moving in the sea or the waves are bumping, the coordination state of the long pole in the support part 132 and the side block part 133 is dynamic, that is, the long pole can be slightly displaced forward and backward in the triangular structure surrounded by the support part 132 and the side block part 133, and the movement of the long pole is buffered by the deformation state of the support part 132, and the non-deformable state of the side block part 133 allows both to cooperate with the support part 132 to shake to a certain extent while limiting the long pole, which overall alleviates the impact of the bumps in the sea and ensures the structural locking with a dynamic structural state. It should be pointed out that the sea environment that the seedling collection of the present invention needs to reach does not have very strong winds and huge waves, so the structural design of the placement member 13 can maintain its buffering performance and structural locking performance under smaller wind and wave conditions.

[0043] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
