Abstract

(57) [Summary] [Purpose] To provide an offshore aquaculture facility that is low in cost, obviates the need for offshore fishing, and minimizes damage during abnormal sea weather. [Structure] A station 1 which is a floating structure anchored offshore is provided with a detachable and towable cage 7 via an anchoring device 8.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an offshore aquaculture facility.

[0002]

[Prior Art]

 Conventionally, offshore aquaculture facilities are composed of a floating structure (hereinafter referred to as a “station”), which is a core base, and a wave-resistant cask. There is a separate type and a self-mounting type that integrates a station and a cage.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned separated type, although the feeding hose installed between the station and the cage is used for feeding, this feeding hose is overloaded and requires an expensive feeding hose to withstand this, In addition, wave life is required for the squid, and it is necessary to make the sack frame a flexible structure, but this increases the cost, and the net hung on the sack also causes excessive stress, which causes various problems. There was a problem such as causing the problem of.

[0004] In addition, the self-loading type does not require the wave resistance as much as the separated type because the fish itself is incorporated in the station, but it is necessary to take offshore once to catch the cultured fish. Therefore, there is a problem that not only excessive stress is applied to the cultured fish taken offshore, but also descaling occurs to reduce the commercial value.

Furthermore, in both of the conventional facilities, since the squid is anchored to the surface of the sea or a station, if a typhoon or other sudden surge occurs, the squid net may blow up and the aquaculture fish may be destroyed. .

The present invention solves the above problems and provides an offshore aquaculture facility that does not require expensive materials, can be manufactured at low cost, does not require offshore fishing, and can minimize damage during abnormal sea weather. With the goal.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises a floating structure anchored offshore, and a detachable and towable cage which is attached to the floating structure via an anchor.

[0008]

[Action]

 According to the above configuration, since the bobbin is usually moored to the floating structure by the mooring tool, the cauldron does not need to have a large wave resistance unlike the separated type, and an expensive feeding hose can be eliminated. Moreover, when harvesting aquaculture fish, it is possible to tow a fish in the vicinity of the point of consumption without catching it offshore, and the fish will not be damaged. Moreover, during abnormal sea weather, the cage can be evacuated to a safe still water area.

【Example】

 An embodiment of an offshore aquaculture facility according to the present invention will be described below with reference to the drawings. 1 is a station composed of a floating structure moored offshore by a mooring device 2, which is provided at one end of the main beam 1a and has a rest / control room 3 with various monitoring devices, a feeding device 4, a feed storage facility, and a power source. A first floating body 1b provided with a device and the like, a second floating body 1c having a spare chest 5 provided at the other end of the main beam 1a, and projected on both sides of the main beam portion 1a at regular intervals. The mooring beam portion 1d is included. In the mooring space 6 formed by the main beam portion 1a and the mooring beam portion 1d or the first floating body 1b or the second floating body 1c so that the outer portion thereof is open, a detachable / towable type casket 7 is moored. It is tethered detachably via. Each of these cages 7 is composed of a substantially pentagonal floating frame 7a whose outer front corners are slanted in plan view to reduce propulsion resistance, and a net 7b which closes the bottom of the floating frame 7a. The front part of the floating frame 7a is connected to the towing vessel 9 by a towline 9a so that the towing vessel 9 can tow it. Reference numeral 10 denotes a feeding hose arranged along the main beam portion 1a from the feeding device 3 to feed the food to each of the cages 6.

In an offshore aquaculture facility, a large pantry is indispensable in order to reduce production costs, but on the other hand, it is necessary to take offshore once for catching fish. However, according to the above-mentioned embodiment, since the detachable / towed type skein 7 is provided, it is possible to tow and catch the fish near the consuming area without taking offshore, and the fish body is not damaged. In addition, depending on the amount of consumption, it is possible to deliver the livestock 7 to multiple consumption areas. In addition, when abnormal sea weather is expected or when a red tide occurs, it is easy to evacuate the cage 7 in advance to a quiet area or a safe area, and the damage can be minimized. The station 1 can also be moved.

[0011]

[Effect of the device]

 As described above, according to the present invention, since the anchorage is normally anchored to the floating structure by the anchorage, large wave resistance is not required for the anchorage like a separate type and an expensive feeding hose is not required. It can be done at low cost. Moreover, when aquacultured fish is caught, it is possible to tow the ikese to the vicinity of the consumption area without catching it offshore, and the fish will not be damaged. Moreover, in the event of abnormal sea weather, it is possible to evacuate the cage to a safe still water area and minimize its damage.
