The present invention relates to a fish farming method and a device for enabling the circulation movement mode.

Conventional fish farming has been farmed by consistently farming one bucket as a whole until the fish grown from the offspring of the fish, or by moving to a bucket of large water passage area and volume as the fish grows. However, when a single bucket is used for aquaculture, only the number of fish pups that grows in one bucket can be farmed. To increase the yield, the number of buckets increases, and Waste was too high efficiency. In addition, changing the water tank or moving fish according to the growth of fish takes a great effort in fish farming, and there is a group of people who are injured in farmed fish according to this work, and the cost of work is reduced at the same time as product value falls. .

SUMMARY OF THE INVENTION The present invention has been accomplished in view of the above point, and an object thereof is to provide a fish farming method and apparatus for enabling a circulation movement mode in which fish farming operations can be reduced and efficient farming can be achieved.

The fish farming method according to the present invention that solves the above problems is partitioned by a fixed net partition and a movable net partition provided between the inner and outer buckets of concentric circles between the central support base and the bucket frame in the inner bucket. At the same time, it divides according to several movable screen partitions which are supported to move on the frame of the bucket from the outer bucket to the center of the bucket. And form a section with the area of fish, and move the fish farm as the movable network screen moves to the corresponding position of each section according to the growth from the new structure of the fish to the section of the fish which grew sequentially to the section corresponding to the next growth period. Drive out the grown fish to supply new fish cubs to the pups of the empty fish. It is characterized by a circular movement mode.

The fish farming apparatus according to the present invention by implementing the above-described fish farming method is a bucket of the inner and outer family in the shape of the crew, the inner bucket has a fixed mesh screen between the support base and the bucket frame of the center; It installs a movable partition supported on the prop and bucket frame and forms a compartment with the surface area according to the new structure of the fish and the next growth period.The outer bucket is supported by the bucket frame around the center circumference. By installing several movable grid partitions, it forms several compartments with bucket water surface area corresponding to the growth period sequentially. At the same time, the tank frame of the inner tank is provided with holes for driving the compartments of the outer bucket on both sides of the fixed grid. In the bucket frame of the outer bucket, there is a hole to drive out the growing compartment of the growing fish to enable circulation movement. It is characterized by being made.

According to the fish farming method and apparatus according to the present invention as described above, opening the hole for driving the grown fish of the grown fish compartment in the outer bucket into the shipping compartment, and then forming the grown fish compartment, The fish farm is moved to the growing fish compartment as the movable grid is moved to the position of formation of the growing fish compartment. . The fish farms in each growth compartment are moved by the movement of the movable grid into the growth zone following the sequential increase in the surface area of the bucket. The empty compartment formed by the other movable network partition and the movable network partition on the other side is driven out by the movement of the movable network partition from the hole driven by the carp from the inner bucket.

The movable network partition of this inner bucket is moved back to form the baby compartment of the fish following the fixed network partition, etc., and the compartment, which has been the baby compartment of the fish until then, is formed into the next growth compartment by increasing the water surface area of the bucket. The offspring of the fish can start farming with the offspring of the same number of fish in each compartment on the same day as the growth compartment.

Such a circular movement form makes aquaculture simple and efficient.

Next, an embodiment of the present invention will be described with reference to the drawings.

1 is a schematic diagram of a fish farming device that best illustrates the characteristics of the present invention, and includes an inner bucket A and an outer foot bucket B having a concentric shape.

In the inner bucket A, the first compartment (1) and the second compartment (2), which are the baby compartments of the fish, are formed, and in the outer bucket B, the fifth compartment, which is the third compartment (3), the fourth compartment (4), and the growth compartment, is formed. The partition 5 is formed. These divisions were determined by dividing the growth period as shown in Table 1, which employs a growth example of the terrapia culture, and the water surface of the bucket according to the number of divisions in consideration of the size of fish farming in each normal period.

TABLE 1

In the inner bucket A, each of the compartments (1) and (2) is supported by a fixed mesh diaphragm (7) and the support (15) provided between the inner bucket frame 16 and the support base 14 and movable support beams ( The partition 8 formed in 8) is formed, and the movement from the first compartment 1 to the second compartment 2 may be performed by moving the movable network partition 8 to the position of 8 '. The inner barrel frame 16 is provided with holes 12 for driving the outer bucket B on both sides of the fixed mesh screen 7 so that the fish farm of the second compartment 2 opens the driven hole 2 to open the movable net. The fish farming can be driven into the third compartment 3 only by moving the membrane 8 to the hole 12 into which the membrane 8 is driven. Then, when the movable network partition 8 is returned to its original position and fixed at the position of the dotted line 8 ', a new first compartment 1' having the same water surface area as the first compartment 1 until then is formed. The 1st compartment 1 until then becomes the 1st compartment 2 'of which the water volume of the water surface was increased.

Next, as shown in FIG. 2 and FIG. 3, the outer bucket B has one end supported by the central column 15 so as to be free to rotate, and the other end and the middle part of the bucket frame 16 and 17 by the wheels 18. Movable docks 9 ', 10', and 11 'supported to move upwards were provided, and each of the movable docks 9', 10 'and 11' was provided with a first and a second one. 3, movable network partitions 9, 10, and 11 are provided.

The third compartment (3) is formed by the first movable network partition (9) and the second movable network partition (10) by the second movable network partition (10) and the third movable network partition (11) by the fourth compartment. (4) and the fifth compartment 5 is formed by the third movable net partition 11 and the first movable net partition 9.

The fifth compartment is provided with a hole 13 which is driven into the bucket frame 17 to connect the shipping compartment 6 provided separately from the outer bucket 17. The first movable net partition 9 is installed so that the driving holes 12 of the inner bucket frame 16 and the driving holes 13 of the same bucket 17 are located on opposite sides of the third compartment 3, respectively. ) And the fifth compartment 5 are formed. When the third movable network partition 11 is moved close to the first movable network partition 11 by opening the hole 13 for driving the grown fish having finished the fifth compartment 5, the shipping compartment 6 Can be moved to

As shown in the dashed line arrow in FIG. 1, when the movable network partitions 9, 10, and 11 are sequentially moved, a partition of the water surface surface area of the next growth section is formed. The bottom surface of the water tank 19 and the water surface 20 are generally 1m deep. In the outer tank B, the movable docks 9 ', 10', and 11 'equipped with the movable network screens 9, 10, and 11 are supplied to the management work along with feeding and other operations. It can be used effectively. Each barrier is netted, and the bucket is circular, so depending on the fish species, the water flows in the bucket, so the circular motion with less resistance is possible.

Next, the circulation movement mode in the fish farming apparatus of the above structure is demonstrated. In this case, the number of aquaculture fish in one compartment is the same quantity in each compartment from the offspring of the fish. It is assumed that the juvenile compartment can be adjusted to the first and the fifth segment of the sequential can be adjusted by the movable screen.

In the same period in each of the compartments 1,2,3,4 and 5, in the case of the terrapia style, when the two-month form has expired, the movement of the fish as the next compartment may be carried out in the following order.

(1) The fish grown in the fifth compartment (5) opens the driving hole (13) leading to the shipping compartment (6), and then the third in the rear of the fifth compartment (5) in the right direction of the outer outer barrel A of the circle. By moving the movable network partition 11 to the position of the first movable network partition 9 in front, it moves to the shipping compartment 6, and the fifth compartment 5 becomes an empty compartment.

(2) The farmed fish of the fourth compartment 4 likewise drives the rear second movable network partition into the fifth compartment 5 as it moves to the rear position of the fifth compartment 5. Therefore, the fifth compartment 5 is formed by the third movable network partition 11 and the second movable network partition.

(3) The cultured word of the third compartment (3), like the cultured word of the fourth compartment (4), is simply rotated to the fourth compartment (4) of the second movable network partition (10) and the first movable network partition (9). Can move.

(4) When the third movable network partition 11 behind the fifth compartment 5 is moved to a certain position behind the third compartment 3, the cultured fish of the second compartment 2 in the inner bucket A The opening 12 of the inner bucket frame 16 through the third compartment 3 is opened, and the movable network partition 8 in the rear of the second compartment 2 is directed toward the fixed network partition 7 in the front. As it moves, it can be driven into the third compartment (3).

(5) When the movable network partition 8, in which the second compartment 2 is formed, is returned to the dotted line position 8 ', the second compartment 2 until then becomes the first compartment 1', and the first compartment. (1) becomes the second compartment 2 'and becomes an empty compartment. The new first compartment 1 ', which is a vacant compartment, enters the pups of the same number of fish as each compartment on the same day as the fifth compartment 5, and can start farming.

Moreover, the driving hole 12, which was not used in the stroke of the movable mesh partition 8 of the driving hole 12 provided in the bucket frame 16 of the inner bucket A, has the second compartment 2 'when it is circulated next time. ) Is used to drive the farmed word of) into the third compartment (3).

In the case where the circular movement mode is the first time, the above administration shall be carried out in reverse order up to the idiom compartment of the fifth compartment (5). In contrast to the case of the terrapia culture in which the circulating transfer mode (I) in the fish farming apparatus described above is consistently farmed (II) with one bucket from the offspring of the conventional fish to the fish grown in the entire bucket. It is evident that there has been a significant improvement.
