Description

349004

Field of invention

[0001] The present invention relates to a method for monitoring of individual fish in a fish population. More specifically, the invention relates to a method for bringing individual fish in a position allowing for observation and registration of individual characteristics for the individual fish for a period necessary for the observation and registration.

Background

[0002] Fish farming has developed over the last few decades from small fish farms with a limited number of fish to large industrial plants in net cages or other cages / tanks in the sea, or in tanks arranged onshore, each with a large number of fish.

[0003] As the fish farming has become more and more industrialized over time, the requirement for monitoring the biomass, fish growth /weight gain, state of health, weight distribution and average weight of the fish, etc. are all important parameters for operation of a fish farm. An early approach to get this kind of data was to catch a small number of fish and perform manual measurements and registration of the required data. However, the practice of catching fish with a hand net, or the like, and doing manual measurements of the fish, is neither practical nor contributing to adequate fish health in large, industrialized plants.

[0004] Several approaches have been made to automize monitoring of important parameters in a dense fish population in a fish farm, by using camera and/or different detectors arranged in a sea cage or tank. However, in a dense population it is difficult, if possible, to measure the necessary parameters one fish at a time, which is necessary for different purposes, as the individual fish is not correctly aligned for observation and measurements, as the fish to be measured is partly covered by other fish, as the fish to a large degree is standing still, or due to turbidity or coloration of the water.

[0005] US 20140376783A1 relates to a system for uniquely identifying subjects, like fish, from a target population to perform population and/or biological monitoring. Pictures are taken of individual subjects, such as fish, the pictures are analyzed in real time or off-line to recognize species and/or the actual individual fish, by comparing the characteristics in a picture with data in a database. Preferably, a subject positioning apparatus is used to bring the fish in position for imaging.

[0006] WO2017137896A1, to Biosort AS (NO), relates to a device and a method for recording and monitoring health and development in living fish in a fish farm.

Individual fish are caused to swim from one chamber to another trough fish scanner device wherein the fish are individually scanned for identification and monitoring.

[0007] WO2020013707, to Mowi ASA, relates to a device and method for retaining fish in a fish cage compartment for treatment and/or observation of the fish. The fish cage compartment is arranged within a fish cage, and fish are allowed to swim into the compartment through a separation device illustrated by a tapered channel

349004

allowing the fish to swim into the compartment, but not out again. The fish may be treated by chemicals inside the compartment and may be allowed to leave the compartment through a channel which includes cameras or the like for observation of the fish.

[0008] CA1336276C, to Re Tech Ltd, relates to an inventory system in which fish are guided into channels for examining individual fish as they swim through the channels. Means, such as video, sonar or light scanners, are arranged for examination of the fish. Water jets introducing water into the channels countercurrent to the swimming direction of the fish, are preferably arranged to encourage the fish to swim through the channels.

[0009] Accordingly, both the concept of bringing an individual, such as a fish, in a defined position for imaging or monitoring, to ensure the quality thereof, and the use of imaging for recognition of individual fish based on such images, are known.

However, there is need for an improved method and device for singulation and monitoring fish in a controlled environment, such as in a tank for fish farming.

[0010] However, there is a need for in improved method for singulation and positioning of fish for imaging for identification of individual fish, calculation of fish weight, and/or analysis of health parameters, and a device for performing the method.

Summary of the invention

[0011] According to a first aspect, the present invention relates to a method for aligning and positioning individual fish in a body of water for imaging for identification of individual fish, calculation of fish weight, and/or analysis of health parameters, the method comprising allowing fish to enter and swim freely through a tube or channel having a width allowing one fish at the time to swim through, imaging the individual fish during their passage through the tube or channel for identification of individual fish, calculation of fish weight, and/or analysis of health parameters, wherein water is introduced into the channel or tube directed to one end of the channel or tube to create a current to attract fish and cause the fish to swim through the channel or tube, where t the introduced water is colder than the water in the body of water. The water introduced has preferably a temperature from 1 to 5 degrees Celsius, such as 2 to 4 degrees, lower than the temperature of the water temperature in the body of water.

[0012] The water introduced into the channel or tube is preferably aerated to increase the oxygen saturation thereof. Aerated water attracts fish.

[0013] According to one embodiment, the body of water is a cage net or a tank.

[0014] According to sill an embodiment, the cage net of tank has a circular horizontal cross section.

Short description of the figures

[0016]

Figure 1 is a bird’s eyes view of a first embodiment of a device according to the present invention,

Figure 2 is a partly cut through side view of the device of figure 1, seen radially from inside of the tank towards the tank wall, and

Figure 3 is a bird’s eye view of a second embodiment of the invention seen from a first angle,

Figure 4 is a bird’s eye view of the second embodiment, seen from a different angle.

Detailed description of the invention

[0017] The present invention is based on the natural behavior of fish in a fish population where fish always tends to turn head-first against the current. This natural behavior may be enhanced by using an incoming flow of water which is faster flowing, cleaner, colder and/or more oxygenated water than the surrounding water.

[0018] The present method and device may be used both in fresh-water, sea water and brackish water. Additionally, the method and device may be used in a fish farm, such as in a net cage, or a tank, and in an open body of water, such as a river, a creek, a lake, in a fiord or out in open sea, even if most of the description herein is directed to the use in a sea farm, such as a tank.

[0019] In the present description and claims the term “fresh water” is used about water that is introduced into the present device to create a flow through the device. The “fresh water” introduced into the device to create a flow does usually have a salinity close to the surrounding body of water. However, the “fresh water” normally has a lower temperature, a lower turbidity, and/or a higher oxygen concentration than the surrounding body of water. In the present description and claims the term “fresh-water” is used about water of low salinity as found in most rivers and lakes.

[0020] Figure 1 is a bird’s eye view of a positioning device 1 according to the present invention arranged to a wall 2 of fish tank having an open top. Depending on size, such tanks may be used for juvenile fish and smolt, and for adult fish. Tanks with open top may be arranged onshore or floating in the sea. Such tanks do normally have a circular cross section. Water is normally introduced along the outer wall of the tank, and parallel to the wall, to create a circulating current in the tank. The fish present in the tank will swim towards the flowing water, and normally the speed of the flowing water is adjusted so that the average speed of the fish closest to the wall is close to the speed of the flowing water. Accordingly, the swimming fish seems not to move for an observer looking into the tank.

[0021] The embodiment in the figures is adopted to be arranged along the sidewall of a tank. A frame 3 is arranged to be connected to sidewall 2 of the tank. The frame 3 may be adjustable or may have specific connectors to be fastened to specific

349004

connectors in the tank wall, or the frame may be connected to any supporting structure being a part of the tank or being arranged over the tank top.

[0022] The present device 1 comprises a channel 4, comprising a sidewall 5, a floor 6, and a rear wall 7, connected to the frame 3. A camera box 8 is connected to the rear wall 7. The camera box 8 is arranged in a cut out part of the rear wall 7, or behind a transparent part of the rear wall, and may contain one or more camera(s), and one or more sensor(s).

[0023] A funnel 9 is arranged at a first end of the channel 4, to serve as a guiding means to lead fish swimming into the funnel towards the channel. In the illustrated embodiment, the funnel 9 is formed by three plates, of which one, in the illustrated embodiment, is an elongated part of the sidewall 5. The skilled person will understand that the part of the sidewall 5 which is a part of the funnel, may be angled relative to the straight part of the sidewall 5 to widen the opening of the funnel 9. A funnel rear wall 10 is connected to the rear wall 7 and is angled outwards from the rear wall 7 relative to the channel 4. A funnel floor plate 11 is angled downwards from the floor 6 in the channel 4. A water inlet 12 is arranged in the part of the funnel floor 11 that is closest to the floor 6 of the channel 4. A water pipe 13 is arranged lead incoming water from a not shown water hose to the water inlet 12. The skilled person will understand that other guiding means may be used to replace the funnel.

[0024] Figure 2 shows the same device in different views to better illustrate all features of the device. Figure 2 shows the device of figure 1 seen radially from inside of the tank towards the side of the tank and shows fish entering the funnel part and fish leaving the channel 4. The sidewall 5 is partly cut through to show features that are not visible during use of the device. The device 1, or the water level in the tank, is adjusted so that the water surface 15 defines the upper limitation of the water volume in the channel 4. Fish 14 entering the funnel 9, a fish 14a in position for observation in front of the transparent window in the camera box 8, and fish leaving the channel 4, are illustrated. One or more camera(s) 16, and any sensors 17, are arranged in the camera box 8.

[0025] Fresh water to be released through the water outlet 12, is in the illustrated embodiment introduced via the water pipe 13 into a water chamber 18 arranged below the channel 4. Mixing arrangements for introducing air or oxygen into the water before being released through the water outlet 12 may be arranged in the water chamber 18. Alternatively, an air diffusor 19 may be arranged in the water chamber 18, receiving air from a not shown air tube. The skilled person will understand that the water chamber 18 may be omitted and that incoming water may be released through water outlet 13 directly from the water pipe 13. The skilled person will also understand that a part of the water introduced through the water pipe 13, or an additional water pipe, may be introduced into the channel 4 upstream to the camera box 8 to reduce the turbidity of the water in the area in front of the camera box.

349004

[0026] When the positioning device 1 is placed in a tank having a circular cross section, as shown in figure 1, the length axis of device 1 is arranged to be perpendicular to a radius of the tank and crossing the channel 4. The present device is arranged with the funnel facing downstream relative to the water flow in the tank. The edge of the funnel rear wall 10 being closest to the sidewall 2 of the tank is preferably so close to the sidewall that it prevents fish 14 from entering between the sidewall and the funnel rear wall. The vertical position of the present device is also adjusted so that the water surface 15 in the funnel is sufficiently high over the channel floor 6 to allow the fish to swim through the channel, and to cover the transparent part of the rear wall 7 of the camera box 8. Optionally, a not shown roof plate may be arranged at the top of the channel to make a tunnel for the fish to swim through. Possible advantages by using a top plate will be that it may reduce splashing in the channel caused by waves at the surface caused by the fish therein, and that the device may be lowered deeper into the tank to register fish swimming deeper in the tank.

[0027] Fish 14 swimming against the current in the tank and being close to the positioning device 1, will be drawn towards the funnel due to a flow of fresh water introduced into the tank from the water inlet 12. The turbidity of the water circulating in the tank is normally relatively high, and by introducing freshwater, optionally water having temperature being colder than the water in the tank and/or having a higher level of oxygen, will cause the fish to swim towards this introduced flow of water and into the funnel. Due to the shape of the funnel, and the width of the channel 4 only one fish at the time will swim into the channel 4. The width of the channel 4 has to be customized to the average size of the fish in the tank, to prevent two or more fish to swim side by side through the channel. The skilled person will understand that the width of the channel, may be adjusted by shifting relative positions of the side wall 5 and the rear wall 7, or by shifting the position of the camera box 8, to widen or narrow the channel 4.

[0028] As soon as one fish is inside the channel 4 in position in front of the camera box 8 in a fish monitoring position 14a, a camera and/or other sensors inside the camera box 8 may take the necessary pictures and/or film, and/or register necessary data for the individual fish. Due to the relatively short and clearly defined distance from the camera and/or other sensors, and the sidewall 5 and the fact that only one fish at the time is in front of the camera box, perfect conditions for all photographs and other observations are maintained.

The fish will not stay in the channel 4 and is not able to turn and swim back as the channel is too narrow. Accordingly, the fish will swim out of the channel and into the surrounding water to allow the next fish to enter the channel. After leaving the channel the fish will continue swimming against the current in the tank. Fish will continue swimming through the present device, to allow for registration of important data for all fish in the tank. Such data can be used to register and monitor the size, weight, and any visible health issue for each fish, and for the fish population. Such

349004

data is valuable for calculating feeding requirement, fish health, etc., and if any actions should be taken. At least for some fish species, such as trout, each individual fish may be recognized and monitored during the stay in the tank by means of the present device.

[0029] The device illustrated in figures 1 and 2 is adapted to be arranged at a predefined height along the tank side wall 2. However, in operation of large fish tanks, the water level in the tank may shift. The skilled person will understand that the positioning device preferably is connected to means to constantly adjust the level of the device according to changes of the water level in the tank, without leaving the spirit of the invention.

[0030] The devise illustrated in figures 1 and 2 includes one camera arranged to take pictures from one position to allow for a two-dimensional picture of the fish. The skilled person will, however, understand that it is possible to arrange cameras at other positions in the device to allow for three dimensional pictures from different positions to allow for better analysis of the fish passing through the device.

[0031] Figures 3 and 4 illustrate an alternative embodiment according to the present invention. The device illustrated in figures 3 and 4 comprises a tunnel 20 preferably having a rectangular cross section. The tunnel 20 is made of plates and/or sheets, such as plates / sheets of metal or a polymer material, such as acrylic or polycarbonate. The presently preferred materials for the tunnel 20 are transparent materials such as acrylic or polycarbonate sheets. Using transparent materials makes inspection and cleaning of the present device easier than if not transparent materials are used. In addition, if transparent materials are used, the light conditions inside the funnel are the same as the ambient light conditions, which is assumed to be less stressful for the fish. The skilled person will understand that the funnel may be made using combination of transparent and not transparent materials.

[0032] The tunnel 20 is open in both a first, or downstream, end 21 and a second, or upstream, end 22 of the tunnel 20. The flow of water from the surroundings into the upstream end of the device is limited by means of flow limiting plates 25, 26 arranged respective side walls 27, 28 of the tunnel 20 partly across the upstream opening 22 to reduce the opening thereof and thereby the inflow of surrounding water.

[0033] The downstream end 21 is open to allow fish to swim into the tunnel 20.

Guide walls 29, 30 are arranged to form a funnel to narrow the opening though which the fish may swim to hinder more than one fish at the same time to swim through narrow end of the funnel and into an observation chamber 31. Cameras 32 are arranged to take photos of the fish passing though the observation chamber 31 for identification, weight calculation, health observation, etc. according to wellknown methods as described with reference to figures 1 and 2. The guide walls 29, 30 are preferably made of a lattice, grid, perforated plates, or the like, that allows water to flow through.

349004

[0034] Downstream nozzle tubes 33, 33’, are arranged to spray fresh and preferably cold water towards the downstream end 21 though the guide walls 29, 30. The downstream nozzle tubes 32, 33 receives the water through a downstream water pipe 34. As described for the device according to figures 1 and 2, an air diffusor 19 may be arranged downstream of the observation chamber 31. Alternatively, the water introduced to the nozzle tubes 32, 33, may be aerated in a separate aeration unit.

[0035] Upstream guide walls 35, 36 are arranged upstream of the observation chamber 31 to guide the fish out from the observation chamber and to an exit opening 37 formed between the flow limiting plates 25, 26. The upstream guide plates are made of the same type of material as the downstream guide plates.

Upstream nozzle tubes 38, 39 are arranged to spray fresh water through the upstream guide plates to provide fresh and clean water to the observation chamber 31, and to create a water flow to cause the fish in the observation chamber to continue swimming out from the tunnel 20. The upstream nozzle tubes receive water from an upstream water pipe 40.

[0036] The upstream and downstream guide plates are arranged both guide the fish into and out of the tunnel 20. Additionally, the guide plates are also arranged to avoid creating pockets or spaces where fish may be trapped.

[0037] The skilled person will understand that even if the illustrated embodiment has two cameras arranged at opposite side walls of the tunnel, more than two cameras may be used. Additionally, cameras may also be arranged in the top and/or bottom of the observation chamber. Additionally, light sources may be arranged to improve the light in the observation chamber. The skilled person will understand that even if only cameras are mentioned for observation / monitoring of the fish swimming through the tunnel 20, other detectors may be arranged in the observation chamber 31 or in other positions of the tunnel 20 if needed.

[0038] The water in tanks for fish farming may have high turbidity. The introduction of fresh water through the upstream nozzle tubes will reduce the turbidity of the water inside the observation chamber 31, and thereby improve the quality of pictures taken. Additionally, a cross-spraying nozzle tube 41 may be arranged to spray water across the length axis of the tunnel 20 close to the exit opening 37. The water sprayed from the cross-spraying nozzle tubes 41 forms a “curtain” which substantially reduces the ingress of turbid water from the surroundings into the observation chamber. Preferably, a water curtain channel 43 formed by the top and bottom parts of the channel 20, the flow limiting plate 26, and a curtain channel plate 26’, is arranged opposite the exit opening 37.

[0039] The channel 20 according to this embodiment may be controlled by means of the water tubes 34, 40 or any separate control rods connecting to suitable stand.

Example

349004

[0040] The present device according to figures 1 and 2 and method have been tested in a tank for salmon juveniles and smolt. The tank has a circular cross section, and water is changed by withdrawing water from a side-wall drain of the tank, and where fresh water is introduced through nozzles directed horizontally and perpendicular to a radius from the tank center through each nozzle to create a circulating current in the tank. The instinct of the salmon juvenile is to swim towards the current. The circulating current in the tank was, as normal for such tanks, regulated so that the current has substantially the same speed as the salmon juveniles swimming close to the tank wall 2, resulting in that the juvenile fish seems to be swimming without moving relative to the tank.

[0041] The present positioning device 1 was arranged to the tank wall 2 so that the funnel 9 is opening downstream relative to the current in the tank. The positioning device 1 creates a hindrance to the circulating current, and thus reduces the speed thereof behind the device 1. Fresh water, preferably slightly cooler than the water in the tank is introduced through the water inlet 12 being arranged so that the fresh water is mixed with the water flowing through the channel 4. Salmon juveniles swimming close to, and behind the positioning device will swim towards the fresh and cool water and is guided into the channel 4 by a funnel 9 formed by the sidewall 5, the rear wall 7 and the funnel floor plate 11. As soon as the salmon juvenile is inside the channel it will continue swimming through the channel 4. When the juvenile is in a fish monitoring position 14a, the camera and any other sensors is in perfect position for imaging. One or more images are taken and sent to a computerized system for identification of the individual fish, identification of any damages thereto, calculation of weight etc. according to well-known methods.

[0042] During a test period of 7 days, the salmon juveniles shifted position constantly, and different individuals passed through the positioning device. Each individual passed though the device without stopping in the channel 4. The time it took for each individual to pass the monitoring position 14a was sufficient for imaging. All individuals entering the channel continued through the channel to give place for the next in line.

[0043] Weak, dying, and dead fish tends to float for a limited period before sinking in the tank. During the test it was observed that the weak, dying, and dead fish floating in the tank was led towards the tank wall 2, and was captured between the positioning device, more specifically the funnel rear wall 19 and the tank wall.

Accordingly, by adding a collection net to the positioning device to collect weak, dying, and dead juveniles, the known problem related to dead fish clogging the outlet from the tank, will be substantially reduced, or even avoided.
