Description

This plan relates to the growth of shellfish and crustaceans, and specifically relates to the prevention of food damage caused by natural enemy species such as conch shells and sea bream, the loss of sea sand, the modulation of nutrient content in water, and the reduction of aquaculture tidal flats due to sludge and plankton. It is related to aquaculture rods that can always operate stable shellfish and crustacean aquaculture business.

According to the conventional technology, a thin long rod is bent to create a rectangular frame (see, for example, Patent Document 1), which is installed in a tidal flat so that natural enemy fish such as flying fish and black sea bream cannot enter the frame. There are things that have been made, and those that have tidal flats surrounded by a net. On the other hand, in the case of conch shells, there is only a method at this stage to capture and discard eggs by human hands at the spawning season to reduce the reproduction of the conch itself. On the other hand, in the Seto Inland Sea, in addition to the above problems, as a result of continuing to remove seabed sand for many years, the sea sand of the tidal flats has been washed away, and the tidal flats as aquaculture for marine products are decreasing, and this is secured. Sand is thrown into the tidal flat as much as possible.

  In addition to the above, various methods have been tried to combat bivalve damage caused by natural enemy fish such as black sea bream, black sea bream, etc., and some results have been achieved, but the countermeasure for snails is only an old-fashioned method called human sea tactics, It takes a lot of effort and labor, which is a big burden for fishermen. On the other hand, in addition to the above-mentioned problems, on the coast of the Seto Inland Sea, the amount of tidal flats suitable for aquaculture farms has been decreasing year by year due to the loss of sea sand flow in aquaculture tidal flats. It is true that searching for successors is a big problem, and in any case including these, it is a problem that is urgently expected to be resolved. Also, replenishment of sea sand is not easy and the project cost is not cheap.

  In addition, the aquaculture method based on this plan can be carried out from a small scale in terms of cost and number of installations, and can be easily moved or removed depending on the situation.

  Therefore, this plan was developed in view of the above-mentioned viewpoints, and it is a cultured ridge that can stably cultivate and produce marine products without being affected by sea sand loss, natural enemy species, especially snails, etc. Is to provide.

In general, the main body is shaped like a slope with an acute angle with respect to the horizontal plane, a rectangular vertical wall on the front and back, and a trapezoidal vertical wall on the side that is perpendicular to the horizontal plane and aligned with the height. A horizontally long box-shaped body having a rectangular opening formed on the upper surface,
The bottom wall described above has a wide space with a square shape on both ends in the inclined direction. The bottom wall has a red bean-sized through hole in the entire bottom wall, and is equivalent to a quarter of the rectangular wall. A window with a large fine mesh-like hole is placed in a balanced manner at two locations on the left and right sides in close proximity to the upper end of the front and rear rectangular wall surfaces, and close to the upper end of the side trapezoid wall surface A single window similar to the above is arranged at the center, while providing a band-like ear on the outer periphery of the top opening and the bottom wall, and a main body with a little finger-sized through hole at each of the four corners,
Along the outer periphery of the flat lid having a size corresponding to the outer periphery of the main body opening, a single elongated rectangular member is attached in a state of being engaged with the inner side of the opening, and a mesh hole is provided. The provided window is arranged in a balanced manner on the left and right sides of the flat lid, and through holes of the same size are provided at the four corners at positions matching the holes of the band-like ears of the upper surface opening.

Since the present plan is configured as described above, the following effects can be obtained.

  The above-mentioned cultured culvert is installed so that the bottom wall surface is inclined along the slope of the tidal flat, and the top surface is horizontal, and is fixed to a pile that has been cast in advance through a string in the hole in the bottom ear. And in the same way as the technique applied to the flower pot, crushed stone, sand, and nutrients are combined, put together with juveniles in this aquaculture jar, fixed through the string in the holes at the four corners, and grown in this Is.

  This makes it impossible for natural enemy species such as flying fish and snails to enter the hole by being blocked by a small hole in the aquaculture cage or a crushed stone layer inside. In addition, due to the flow of seawater and waves due to tidal flow, small holes made in the main body and the flat lid always play a role of buffering action, and in the culture trough, gentle up and down and left and right directions toward each hole There is no flow of water, and seawater does not stir the sand and spill out.

In addition, in the holes provided in the main body and the flat lid, the flat holes and the mesh holes on the vertical wall surface act as a water inlet for feeding fresh seawater to the juvenile shellfish, as a countermeasure under hot weather at low tide in the summer, The mesh shape described above has both an effect as a light-shielding net and a ventilation effect, and functions to suppress a temperature rise in the cultured trough.
The convex space having a square shape on the bottom wall surface prevents the main body and the sand surface from contacting each other and causes a flow of fresh seawater below the bottom wall surface to replace the seawater of the cultured trough.

  The main effect of this plan is that it can be found in the planed culverts in the tidal flat where natural enemy species appear, the aquaculture tidal flat where sand is washed away, the tidal flat where there are many pebbles or many silt layers, By recreating the best tidal flats, regardless of the above-mentioned problems, it is possible to plan annual productivity and profit stability as aquaculture business by systematically arranging and managing these cultured troughs on the tidal flat. It is in the point that it can be done.

An embodiment of the present plan will be described with reference to the drawings. In FIGS. 1 to 5, the shape of the main body 1 is generally formed such that the bottom wall surface 2 is an inclined surface with an acute angle with respect to a horizontal plane, and the front and back surfaces are rectangular. The wall surface 3 and the side surface are trapezoidal vertical wall surfaces 4 that are perpendicular to the horizontal plane and arranged at the same height, and are horizontally long box-shaped bodies in which a rectangular opening 5 is formed on the upper surface,
The bottom wall surface 2 described above is formed with a wide space 6 (see FIG. 2) having a wide square shape at both ends in the inclined direction, and is provided with a red bean-sized through hole 7 in the entire bottom wall surface 2. A window 8a having a fine mesh-like hole corresponding to a quarter of the shape of the vertical wall 3 is balanced at two locations on the left and right sides in close proximity to the upper ends of the rectangular vertical walls 3 on the front and back sides. In the trapezoidal wall 4 on the side, one window 8b similar to the above is arranged in the center near the upper end, while the band-like ears 9a and 9b are provided on the outer periphery of the top opening 5 and the bottom wall 2 respectively. A main body 1 having small finger-sized through holes 10a, 10b at the four corners of

  6 and 7, a single elongated rectangular member 12 is moved to the inside of the opening 5 along the vicinity of the outer periphery of the flat lid 11 having a size corresponding to the outer periphery of the opening 5 of the main body 1 described above. The window 8c having a mesh-like hole is arranged in a balanced manner on the left and right sides of the flat lid 11, and is the same size at a position that coincides with the hole of the band-like ear portion 9a of the upper surface opening 5 at the four corners. A through hole 10c is provided.

  The size of the main body is approximately 200L in terms of volume, since empty aquaculture can easily be carried by human power, and the angle θ of the bottom wall surface with respect to the horizontal plane is approximately 3 ° to 8 °. The size of the shape of the hole is preferably in the range of about 1 mm to 3 mm, which is smaller than the sea sand in the cultured trough.
