Description

The present invention relates to a method and an apparatus for counting the number of live fish accurately in water and without stressing the live fish during growth or shipping in a fish farming facility or the like.

As a method for counting live fish that have been released into the cages of aquaculture facilities and the like and a method for counting live fish introduced into the cages, the “total method”, “total reading method”, and “equipment usage method” are known. ing. The “total method” is to collect the fish in one place, scoop it with a tamo net, drain it, weigh the total weight with crisp, and then extract a small amount of fish as a sample. Then, the average circumference is calculated by measuring the weight and number of fish of this sample, and the total number of live fish is estimated by dividing the total weight by the average circumference. The “total reading method” is a method in which a skilled person counts the total number of live fish one by one, and the “device usage method” is a method in which fry fish and the like are read by a sensor while flowing in a water stream.

In connection with the above, live fish comprising counting means having detection means capable of detecting live fish in water, and an approach tank that is connected to a water channel leading to the detection area of the detection means without overlapping live fish, and to which live fish is supplied from the outside In the counting device, it faces the water in the approach tank and is appropriately spaced from the detection means so that it can be moved close to and away from the detection area of the detection means, and the fish can not pass through the gap with the inner wall of the approach tank. An example of a live fish counting device provided with a eviction means provided with a follower is disclosed (see Patent Document 1).

A counting means capable of counting live fish in water is a collection device incorporating a counter comprising a counting frame frame equipped with a counting sensor and a sorting net frame which is equipped with a sorting net and covers one side of the counting frame frame body. The net is submerged in aquaculture cottages, fish cages and other aquaculture facilities, and the live fish is passed through the counter's sorting net and the counting sensor built in the collection net in sequence, thereby counting the number of live fish. A method for counting live fish in water, characterized by counting, has been proposed (see Patent Document 2).

A live fish counting method and an apparatus for providing a live fish counting method that enable mechanization of live fish counting work using an inexpensive and versatile live fish counting device while realizing a small space In the hollow part of the hollow body where both ends are opened, the step of selecting healthy fish from the captured live fish, the step of selecting healthy fish from the captured live fish, and the counting means provided with counting means capable of detecting the number when the fish passes through the selected healthy fish There is disclosed an apparatus comprising a step of putting and a step of moving the healthy fish through the hollow body to a water tank (or a fish cage) capable of accommodating live fish. (See Patent Document 3)

A live fish counter comprising a counting means having detection means capable of detecting live fish in the water, a water channel leading to the detection area of the detection means without overlapping the live fish, and an approach tank connected to the water channel and supplied with live fish from the outside In the apparatus, there has been proposed a live fish counting apparatus provided with expelling means that prevents the fish from passing through the gap with the inner wall of the approach tank (see Patent Document 4).

When the fish enters the passage where the live fish is superposed and cannot swim, and the fish detection sensor facing this passage detects this fish, the shutter engaged with this detection sensor blocks the passage and prevents the fish from retreating. There is a proposal of a live fish counting apparatus comprising a live fish counting method that closes and counts the fish in the fish detection sensor side passage from the shutter with a counting sensor facing the passage (see Patent Document 5).

JP 2001-45905 A JP 2005-102638 A JP 2002-32733 A JP 2001-45905 A Japanese Patent Application Laid-Open No. 6-243311

After collecting the fish and scooping it up with a tamo net, weighing the total weight with the weight, weigh the number and weight of the sample fish, calculate the average circumference, and divide the total weight by the average circumference to estimate the total number of live fish However, there is a problem that the counting method is inaccurate and not objective. In addition to the size of the fish, there are individual differences in the weighing method for obtaining the average scale, so if the measurer is different, the counting results will be different.

The method of counting the total number of live fish one by one collects the fish in one place like the total method, so the fish body is easily damaged, and it requires skill, great effort and time for counting, and the work is inefficient There is a problem that the fish tends to be deficient during counting. Furthermore, the “total reading method” is effective during the juvenile period of fish, but there is also a problem that it becomes difficult to handle fish when the fish size is large. It is difficult to count a large amount of live fish with marine ginger even if it is possible to count at land facilities.

"Equipment usage method" that reads fry fish etc. with water flow sensor is misreading as one when there are 2 fry and 3 fry, or re-read fry that has flowed back, and the counting error is large, Moreover, there is a problem that the target is only fry and cannot be applied to adult fish.

  For juvenile fish, it is possible to count through the water channel using a driving device using the property of swimming along the water flow, but in the case of adult fish it is difficult to drive into the water channel because it does not swim along a small amount of flow, There is also a problem that the water channel has to be deepened and the size of the facility has to be increased. In addition, since the equipment used is large, it is difficult to carry and count between aquaculture facilities.

  Furthermore, counting a large amount of fish at the time of shipment, etc. requires a lot of labor and time, and is inefficient and causes the fish to be depleted due to lack of oxygen due to overtime. In the case of `` Method '', the fish that are violent is scooped with a tuna net and weighed with crisp, so the fish body is easily damaged, and the damage received by the fish body at the time of counting often causes illness during subsequent cultivation .

Therefore, objective and accurate counting can be performed without damaging live fish at the time of counting, and even if the fish is large or small, there is no individual difference and it does not take time, and it is possible to reduce the number of workers etc. and reduce counting cost and labor saving It is an object of the present invention to obtain a method and an apparatus for counting live fish in water that can increase the efficiency of work and can prevent the fish from being deficient during counting.

In the measurement of live fish, the size of the mesh that can be used to sort live fish is different from that of a count frame frame equipped with a count sensor having 1 to 200 passage frames having dimensions of 10 mm to 200 mm × 10 mm to 200 mm. A device that consists of a sorting net frame that is fitted with a sorting net to cover one side of the counting frame frame, and a collection net that is equipped with a counting sensor and that incorporates one side of the counting frame frame, By submerging the fish in a fish farm, fish cage, or other aquaculture facility, and passing the live fish sequentially through a counting screen and a counting sensor built in the collection net, the number of live fish is counted underwater. This is a live fish counting apparatus.

In the counting measurement of live fish, a counting frame frame equipped with a counting sensor having 1 to 200 passage frames having a size of 10 mm to 200 mm × 10 mm to 200 mm in length and width is 1 to 1 in the frame. 20 pieces are installed, and the frame body is made of stainless steel or resin, and the counting sensor is attached to the resin used for the grid of the frame body.

In order not to allow two live fish to pass through the upper part of the counting frame frame at the same time, the passage restriction plate attached according to the size of the live fish has a passage hole size of 1 to 5 different passage restriction plates, and has a shape. The square or circular shape has a dimension in the range of 10 mm to 150 mm in 1 to 5 stages.

In addition, 10 W to 200 W illuminators are attached to 1 to 8 locations below the counting frame frame. The illuminator may be a normal fluorescent illumination lamp, an exothermic illumination lamp, or an LED illumination lamp. In particular, live fish are attracted and easily passed through the counting frame. Moreover, it is preferable that the passage restriction plate has a color that allows live fish to be easily drawn.

A collection network incorporating a counter comprising a counting frame frame equipped with a counting sensor and a sorting net frame equipped with a sorting net and covering one side of the counting frame frame is a square of 5 to 20 m. The mesh was made 5 mm to 30 mm. The collection net is submerged to a position along the bottom of the aquaculture cottage, ginger, or other aquaculture facility, and then gradually lifted to select a counting screen for the live fish incorporated in the collection net. By sequentially passing through a plate and a counting sensor, the number is counted to count the number of live fish.

A collection net incorporating a counting frame frame equipped with a counting sensor and a sorting net frame should be installed in an aquaculture split, ginger or other aquaculture facility that does not contain live fish, and then count. By supplying live fish into the aquaculture facility, the live fish is sequentially passed through a selection frame, a counting frame frame equipped with a passage restriction plate and a counting sensor, and the number of live fish is counted to count the number of live fish.

A counting machine comprising a counting frame frame equipped with a counting sensor and a sorting net frame, an electronic device for displaying a live fish counting signal via a signal line derived from the counting sensor, and the counting sensor includes a light emitting diode. It consists of a plurality of optical signal light emitting units and optical signal sensing units used, and counts the number of times the optical signal is blocked when live fish passes between the optical signal light emitting unit and the optical signal sensing unit. It is a counting device for live fish under contract to be displayed as a counting signal.

As the counting sensor, various types of counting sensors using other radio waves, sound waves, lasers, etc. can be used in addition to those using light emitting diodes.
The collection net 3 is cultivated by using the weight of the counter 20 while feeding the rope 4 out of the winches of the hulls 5 and 5 in the aquaculture cottage, ginger and other aquaculture facilities 2 fixed to the frame 1 The fish 10 in the aquaculture facility 2 is driven so as to be positioned on the collection net 3. You may attach a heavy stone to the collection net | network 3 as needed.

This counting method makes use of the property of raw fish that escapes from the enemy in the opposite direction to the water surface and dislikes touching the air. Since the sorting net frame 15 and the counting sensor 13 are spaced apart from each other, passing through the sorting net 14 of the sorting net frame 15 concentrates live fish, and the counting frame frame body. 6 counting sensors 13 are passed one by one, so counting errors are extremely small.

  The above embodiment assumes an aquaculture facility such as a large aquaculture pond or marine ginger, but in the case of a small aquaculture pond or a ginger, the hull 5 such as a boat and a winch are not necessary, and the rope 4 can be extended and pulled up. It can also be performed manually by the operator.

  According to the method and apparatus for counting live fish in water obtained by the present invention, it counts while swimming live fish using the adult fish's habit of going down against external enemies and hating to touch the air. In addition, there is no risk of damaging live fish as in the conventional example of measuring with crispness, and objective and accurate counting can be performed. In particular, even if the fish is large or small, there is no individual difference like the total reading method, and even if the measurer is different, there will be no difference in the counting results, and the accuracy of counting will be expected even for adult fish as well as fry fish be able to.

  Counting does not require skill, great labor and time, and counting uses electronic devices such as personal computers. Therefore, it is possible to reduce the number of workers, counting costs, and labor savings. There is no worry that the fish will become deficient during counting. Furthermore, since it is not affected by the quantity or size of the target live fish, it can be counted not only by land facilities but also by marine fish cages.

  In addition, according to the present invention, since the quantity of live fish in the cage can be accurately grasped, it is possible to calculate an accurate feeding amount and enable efficient aquaculture, and to establish an appropriate inventory management system for cultured fish. it can. In addition, it is possible to bring about an effect of preventing environmental pollution due to food loss, and it is possible to cultivate delicious fish with tight meat quality.
