    FIELD OF THE INVENTION
    The present invention relates to an underwater harvesting system for harvesting zooplankton, comprising an underwater vessel intended to be submerged into the sea and towed to a surface vessel, comprising a housing provided with an inlet through which zooplankton-containing fluid may flow; a hose mounted on the underwater vessel which is in fluid communication with the inlet, said hose being adapted to attach and fluidly connect the underwater vessel to the surface vessel; and pumping means for drawing a zooplankton-containing fluid through the inlet of the underwater vessel and for pumping the zooplankton-containing fluid through the hose to the surface vessel. The invention further relates to a method for harvesting zooplankton or other marine organisms.
    BACKGROUND OF THE INVENTION
    Plankton is a diverse group of organisms that primarily live in the ocean and include zooplankton, such as krill, among others. Zooplankton is a significant marine resource with significant human and economic potential, but capturing or harvesting zooplankton is difficult for a variety of reasons.
    So far, catching zooplankton has been carried out using large nets or trawl nets with a very small mesh size. One problem associated with the use of nets with a small mesh size is that by-catch can be significant and difficult to prevent. Fish fry or other small species may be unintentionally caught in the nets, which can have serious consequences for the marine environment.
    Fishing of zooplankton and krill using traditional fishing methods is therefore prohibited in most territories globally. Today, commercial fishing for krill is primarily conducted in Antarctic areas, where there is relatively much krill and is caught close to the surface, which helps reduce the risk of by-catch.
    In order to ensure the future food supply to a growing population, ocean resources are an important and nutritionally good source. However, marine resources are scarce and commercial fisheries need to be monitored to ensure future stocks. Thus, fishing technologies and devices are needed to help protect the environment and reduce harmful effects, such as by-catch.
    An improved technology for catching zooplankton and other marine organisms would therefore be advantageous, and in particular, more efficient and reliable by-catch fishing tools would be advantageous.
    OBJECT OF THE INVENTION
    It is an object of the present invention to solve, in whole or in part, the above-mentioned drawbacks and disadvantages of the prior art. More specifically, it is an object to provide fishing techniques and apparatus that can be used to selectively capture specific species in a controlled manner compared to traditional mass capture techniques.
    BRIEF DESCRIPTION OF THE INVENTION
    It is thus intended that the above object and several other objects be achieved in a first aspect of the invention by providing an underwater harvesting system for harvesting zooplankton, comprising an underwater craft intended to be submerged in the sea and towed by a surface vessel. , comprising a housing provided with an inlet through which zooplankton-containing fluid may flow; a hose mounted on the underwater vessel and in fluid communication with the inlet, said hose being adapted to attach and fluidly connect the underwater vessel to the surface vessel; pump means for drawing a zooplankton-containing fluid through the inlet of the underwater vessel and for pumping the zooplankton-containing fluid through the hose to the surface vessel, the underwater vessel further comprising a laser emitting device for emitting light of a predetermined wavelength to promote a defined water region formation of zooplankton shoals in the illuminated watershed.
    A surface vessel covers a number of different waterborne vessels including, ships, boats or cushion boats.
    The underwater harvesting system described herein may also be suitable to be lowered into the sea from land or from floating vessels which may float on the sea surface or located at a desired depth in the sea.
    Thus, the properties of the underwater system are not specifically designed to deliver the harvested living organism to a specific container of the harvested living organism. In this regard, whether the container of the harvested living organism is on land, floats at a specific depth in the sea, floats on the sea surface or on a surface vessel, the underwater harvesting vessel according to the invention can be used without modification to pump the fluid containing living organisms through the hose. to the container.
    The underwater harvesting system is also suitable for harvesting mesopelagic fish, ie. fish that live in the mesopelagic zone and have a length of between 2 and 10 cm. Changes in the characteristics of the underwater harvesting system are not necessary to harvest mesopelagic fish. Thus, in one aspect, the invention relates to an underwater harvesting system for harvesting zooplankton or mesopelagic fish, comprising: an underwater vessel to be lowered into the sea, comprising a housing provided with an inlet through which fluid containing zooplankton or mesopelagic fish can flow; a hose mounted on the underwater vessel and in fluid communication with the inlet, the hose being adapted to attach and fluidly connect the underwater vessel to a surface container for harvested zooplankton or mesopelagic fish, and pump means for drawing fluid containing zooplankton or mesopelagic underwater fish through inlets and for pumping the fluid containing zooplankton or mesopelagic fish through the hose to the surface vessel, the underwater vessel further comprising a laser emitting device or a light emitting diode (LED) to emit light of a predefined wavelength on a defined water region to promote zooplankton formation of voids. or mesopelagic fish in the enlightened watershed. The underwater harvesting system can be lowered into the sea from land or from floating devices which can float on the surface of the sea or located at a desired depth in the sea. In some embodiments, the submerged underwater harvesting system may be towed to a surface vessel.
    This provides a device for selectively capturing specific species such as zooplankton and krill. By adjusting the wavelength of light emitted from the laser or LED, specific species can be attracted to the light and captured. By further adjusting the wavelength of light emitted from the laser or LED, other specific species, such as mesopelagic fish in this regard, can be attracted and trapped. In some other embodiments, a light source other than laser or LED may be used to emit light that will attract zooplankton or mesopelagic fish.
    Furthermore, the inlet in the house can be variable in size, for example to accommodate zooplankton or mesopelagic fish of different sizes. In one embodiment, the underwater vessel may comprise an inlet hatch which covers the inlet and is movable between a closed position where the inlet is substantially closed and an open position where the inlet is fully open. Furthermore, the inlet hatch may be pivotally mounted below the underwater vessel housing and movable between the closed position where the inlet hatch is retracted and substantially flush with a bottom side of the housing and the open position where the inlet hatch extends below the housing.
    By being able to vary the size of the inlet, it is possible to reduce the drag resistance of the underwater vessel and improve the way the underwater vessel travels through the water. This may be advantageous, for example, when the underwater vessel is towed through the ocean in search of zooplankton or mesopelagic fish. When a streak of zooplankton or mesopelagic fish is identified, the inlet is opened to increase the range of the device and improve the catching effect.
    The laser transmitting device or other light source, such as an LED, is further adapted to transmit light having a wavelength of 400-550 nm, preferably about 470 nm. These wavelengths correspond to the natural wavelength emitted by some zooplankton species, such as krill, or mesopelagic fish.
    The underwater vessel may further comprise one or more interchangeable buoyancy adjustment elements to control the buoyancy of the underwater vessel. With a device where the buoyancy can be controlled using a relatively simple means, the device is more robust since complex and fragile systems for controlling the buoyancy can be avoided.
    In addition, the underwater vessel may comprise a camera for recording and transmitting images to the surface vessel. The camera may further incorporate a pan-tilt function so that the underwater vessel environment can be monitored to identify zooplankton or mesopelagic fish. The camera may also be a silicon amplifier target camera for recording images under low light conditions.
    The underwater vessel may also comprise a first light emitting device for attracting zooplankton, or mesopelagic fish, as shown, for example, in Figure 3, ie. the first light emitting device 9. The underwater vessel may also comprise a second light emitting device, such as a high intensity discharge lamp, for illuminating an area surrounding the underwater vessel. The underwater vessel may further comprise an audio device such as a sonar for identifying zooplankton shoals, or mesopelagic fish.
    In addition, the underwater vessel may comprise a built-in propulsion system for maneuvering the underwater vessel underwater. The underwater vessel can hereby be operated independently of the surface vessel. In some embodiments, the underwater harvesting system includes an HIV compensation system to reduce the impact of waves during operation. The HIV compensation system can be an active HIV compensation (AHC) or a passive HIV compensation (PHC) system.
    Active HIV compensation systems may include electrical or hydraulic gaming systems. A control system, such as a Programmable Logic Controller (PLC), calculates and controls how the active parts of the system should respond to the movement induced by the waves.
    Passive HIV compensation systems are characterized by not using electric current and store the energy from the waves and use it at a later date.
    The invention further relates to a method for harvesting zooplankton or other marine organisms, such as mesopelagic fish, using the above described underwater harvesting system, comprising the steps of putting the underwater vessel into the sea, activating the laser emitting device to illuminate a defined water area to promote formation of stimuli of zooplankton or other marine organisms, to drag the underwater harvesting system through the ocean and the illuminated water area, and to activate the pumping means to draw a zooplankton-containing fluid through the inlet and to pump the zooplankton-containing fluid through the tubing. In addition, the method may comprise the step of activating the inlet hatch to move the inlet hatch from the closed position to the open position when a streak of zooplankton has been identified and is within a predefined distance from the inlet.
    Further aspects, advantages and features of the present invention will be elucidated and elucidated with reference to the dependent claims, the description and the accompanying figures.
    BRIEF DESCRIPTION OF THE FIGURES
    The underwater harvesting system of the invention will now be described in more detail with respect to the accompanying figures. The figures show one way of implementing the present invention and are not to be construed as limiting other possible embodiments which fall within the scope of the appended claim set.
    Figure 1 is a side view of an underwater harvesting system;
    Figure 2 is a front view of an underwater vessel with the inlet hatch in a closed position,
    Figure 3 shows a front view underwater vessel with the inlet hatch in an open position, and
    Figure 4 shows an underwater vessel towed after a surface vessel.
    DETAILED DESCRIPTION OF AN EMBODIMENT
    FIG. 1 shows an underwater harvesting system 1 according to an embodiment of the invention. The harvesting device comprises an underwater vessel 2 comprising a housing 21 provided with an inlet 22 shown in FIG. 2. A hose 4 fluidly connected to the inlet extends from the housing. By providing a pumping effect in the hose, fluid containing zooplankton or mesopelagic fish can be drawn through the inlet of the housing and pumped through the hose 4.
    As shown in FIG. 3, the subsea vessel 2 is intended to be used under the sea and towed to a surface vessel 3. The hose extending from the subsea vessel is used to attach and fluidly connect the subsea vessel to the surface vessel. Fluid containing zooplankton or mesopelagic fish can hereby be pumped from the inlet 22 of the underwater vessel to containers on board the surface vessel. The pump means may be provided in a variety of ways known to those skilled in the art. For example, a fluid pump may be connected to an end of the hose opposite the underwater vessel 2. When the pump is used, fluid is drawn through the hose. Alternatively, a compressed air pump may be used where compressed air is introduced into the hose closed to the inlet of the underwater vessel housing. As compressed air enters the tubing and expands, fluid in the tubing is lifted to the surface due to a reduction in fluid density caused by expanding air. Air pressure can come from a compressor located on the surface and supplied through an air hose. The air hose may be built into the hose for carrying fluid containing zooplankton or provided as a separate hose. Alternatively, compressed air may come from containers arranged in the underwater vessel housing.
    The submarine vessel 2 further comprises a device for emitting light such as laser emitting device 6 for emitting light of a predefined wavelength. The light is emitted in a defined water area 7 as shown in FIG. 4, to promote the formation of zooplankton shoals. Wavelength from 400-550 nm, preferably about 470 nm can be used to attract zooplankton such as krill. Other wavelengths can be used to affect zooplankton in other ways. For example, once a zooplankton streak has been formed, emitted light can be used to prevent subsequent spread of the zooplankton, thereby keeping the streak together for as long as possible. The emitted light can thus be regarded as a virtual grid that holds the zooplankton together. In some embodiments, the light emitting device may be an LED.
    Returning to Figs. 1-3, the housing of the underwater vessel may be made of a polymer foam material, such as divinycell, which is a high density medium density cell foam with a high compressive strength and abrasion resistance. By making the housing of such a material, the underwater vessel becomes naturally fluid and very durable and robust. The housing is furthermore provided with an inlet hatch 23 which covers the inlet 22. The inlet hatch is pivotally mounted below the housing of the underwater vessel between a closed position, as shown in FIG. 2, and an open position, as shown in FIG. 3. When the inlet door is in the closed position, the inlet is substantially closed and in the open position the inlet is completely open. In the closed position, the inlet door is further retracted and flush with substantially a bottom side 24 of the housing, and in the open position the inlet door is extended below the housing. In addition, the housing is provided with a skirt 25 along the back circumference.
    The skirt serves to improve the hydrodynamic properties of the underwater vessel and can improve directional stability. The housing may also be provided with one or more fins to control how the underwater vessel moves through the water.
    The underwater vessel may also comprise a control system for controlling various sensors and functionalities such as the inlet hatch. The control system receives input from an operator on the surface, for example via a landline connection running along the hose.
    One or more interchangeable buoyancy adjustment elements are provided in the housing for controlling the buoyancy of the underwater craft. For example, the buoyancy of the underwater vessel can be adjusted according to the depth and speed at which it is towed.
    An important feature of the underwater craft is the ability to select specific species selectively. For this purpose, the underwater vessel may comprise one or more cameras, for example as shown in Figure 3, i.e. camera 8, to record images and send image data to the surface vessel or other location from which the underwater vessel can be controlled. Based on information provided by the images, an operator may control the underwater vessel, for example, by activating the pump means to retract fluid containing zooplankton. If the operator cannot determine a species that surrounds the underwater vessel, he may choose not to activate the pumping means.
    To be able to get a better view of the underwater craft environment, the camera can incorporate a pan-tilt feature so that the camera can be rotated. Furthermore, special cameras such as silicon target-target cameras or other cameras suitable for low light conditions can be used if the underwater vessel is used in places with limited natural light.
    As an adjunct or alternative to the laser transmitting device, the submarine vessel may also comprise one or more light transmitting devices to attract zooplankton or mesopelagic fish. A light emitting device may include RGD LEDs to emit light to attract zooplankton or mesopelagic fish towards the inlet of the house. The underwater vessel may also be provided with a light emitting device, such as a high intensity discharge lamp, to illuminate an area surrounding the underwater vessel. Such light can be used to gain a better understanding of the environment, for example to identify nearby species.
    During use, the underwater vessel is lowered into the sea from, for example, a surface vessel. The underwater vessel is attached to the vessel via the hose and the hose is used to control the towing distance and thus the depth at which the underwater vessel is in use. On the surface, an operator may receive different types of data collected by the submarine. This data can be presented on one or more screens or other types of interface and can be used to operate the underwater craft. At one time or another, the operator activated the light emission, such as the laser emitting device to illuminate a defined watershed to promote the formation of zooplankton or other marine organisms. Based on data collected with different sensors onboard the underwater vessel, the operator can determine when a streak of zooplankton is formed. Based on this information, the pump means can be activated and the inlet opened to capture the shoal of zooplankton.
    Although the present invention has been described in connection with the specified embodiments, it is not in any way to be construed as being limited to the examples given. The scope of the present invention is set forth in the appended claims set. In the claims, the terms "comprehensive" or "include" do not exclude other possible elements or steps. Furthermore, the mention of references such as "one" or "one", etc., should not be construed as merely a plurality. Also, the use of reference characters in the claims with respect to elements indicated in the figures is not to be construed as limiting the scope of the invention. Furthermore, individual features mentioned in different claims may be advantageously combined, and the mention of these features in different claims does not preclude a combination of the features being not possible and advantageous.
