Definitions

  • the present invention relates aquaculture facilities
  • Aquaculture facilities require systematic evaluation and treatment of their fish. It is useful to count the fish and evaluate them for size, growth rate, evidence of disease and presence of parasites. Fish also require processing such as vaccination, parasite removal and sorting. Fish are normally unconstrained within the volume of an aquaculture facility.
  • This invention discloses a system and method whereby the fish are passively or actively constrained without stress to pass through one or several apertures. The apertures are combined with sensors and processing apparatus so that fish are evaluated or treated as desired. This method provides substantially complete information and the opportunity to treat every fish in the facility.
  • Aquaculture operators also require a means for monitoring the size distribution and rate of growth of fish.
  • This invention pertains to supervision of aquaculture facilities in general and, in particular, to the systematic observation, measurement and, where necessary, treatment of diadromous and marine fish in open net, marine aquaculture facilities.
  • the invention is intended for the evaluation of a) the general health and function of the facility, b) the size and growth rate of the fish population (i.e. biomass), c) the quantity of external parasites and d) other indicators of disease in the fish population.
  • An important indicator of general health and function of a facility is the total number of live fish. Operators know how many fish were placed into a facility. Fish may be lost due to either death or escape from the facility (often caused by damage to the containment structure). In current practice, a full count of the fish in a facility is usually only possible when the fish are transferred to another location, often by pumping the fish from the facility into a specialized boat or another facility. Fish counters may be integrated into the pipe from the pumping apparatus, fish may be counted in connection with vaccination or slaughtering, or the total number may be inferred from the weight of the fish. Pumping fish from one location to another is generally stressful for the fish. There is no method currently available for periodic, in situ, stress-free direct counting of fish in an aquaculture facility.
  • biomass in a facility is the sum of the weights of all the fish, either living or slaughtered. It would be advantageous to know the weight of each fish in the facility at a selected point in time. With this information, one could calculate the size distribution of the population, the mean weight, the total weight or biomass and other statistics of interest.
  • biomass in situ biomass in a facility is estimated from a sample of fish that choose to swim through a measurement device (often called a "biomass frame") or close to a camera-based machine vision system. Biomass frames typically use an array of optical sources and detectors to create an estimate of the size of each fish.
  • Machine vision systems do the same based on analysis of the images from two or more cameras.
  • the apparatus may be calibrated for each species to convert the geometrical data to an estimate of live and gutted weight information.
  • Other methods based on acoustics or electrical conductivity have been tried but have not been commercially successful.
  • a disadvantage of the current practice is that only a limited sample of fish is measured, so the measured sample may not accurately represent the entire population. Accuracy estimates range from 2% to 10% deviation from the true biomass. This invention offers the possibility to measure every fish and therefore the precise biomass.
  • Aquaculture operators must also assess the fish population for the presence of external parasites and evidence of disease. For example, in aquaculture of salmon, it is necessary for both legal and economic reasons to assess the fish for the presence of salmon lice.
  • Current practice is to estimate the parasite load at a point in time from a manual count of parasites on a small sample of fish. The fish are normally removed from the water, the number of parasites is counted and the fish are quickly returned to the water. This is very stressful for the fish. Research has been conducted on methods to automatically detect the presence of some external parasites on fish but there is currently no commercially available solution.
  • Health-related treatments are often required over the lifetime of fish in an aquaculture facility.
  • Fish may be individually vaccinated (e.g. by injection) to prevent disease, parasites may be removed, unhealthy fish may be segregated from the general population and fish that have reached a threshold size may be separated for harvesting. All of these tasks may be efficiently accomplished by sequential inspection, measurement and treatment of all the fish in a facility.
  • the only method for systematic, sequential processing of fish is by means of pumping the fish from one location to another by means of specially designed fish pumps. Such pumping operations often require that the fish are anesthetized. With or without anesthesia, the pumping process is generally stressful for the fish. Fish often respond to stress by not eating after the stress, resulting in decreased growth rate and longer time to market which, in turn, is commercially undesirable.
  • US2012132148 from 2004 shows the use of two separate containment structures or 'cages' connected by an underwater tunnel.
  • a 'balloon' is inflated with air or water inside one of the cages thereby reducing its volume and motivating the fish to move into the other cage.
  • This approach requires two cages with twice the volume actually needed to contain the fish and is thus more expensive than necessary.
  • Patent WO2010087722 from 2009 also shows the use of two separate cages with a connecting tunnel between them. The tunnel is described as 'partially submerged' so that the fish may be exposed to air. Also, fish are transported on a moving grid into a treatment bath for the removal of parasites. This invention also requires twice the volume actually needed to contain the fish and is thus more expensive than necessary.
  • Patent WO2012115522 from 201 1 describes an underwater tunnel for the transport of fish from one cage to another in which the fish are guided by a pattern of gas bubbles in the tunnel.
  • fishes in fish control station, has lights working in range of infrared light, and image formed on reference surface Tunnel for underwater optical measurement of fish No uni-directional function

  • Fig 8xx show two such cages connected by a tube with a door operated by the facility operator.
  • the invention provides improved management of an aquaculture facility by evaluating every individual fish in the facility rather than a sample. This is accomplished by a system and method for complete, systematic, sequential, stress-free passage of every fish in a facility through one or several openings or 'doors' in a specified direction.
  • a variety of sensors, measuring apparatus, treatment apparatus and/or sorting apparatus may be placed at each door whereby each fish may be counted, measured, treated or sorted as desired.
  • the characteristics of the system and method are:
  • Passive mode a large sample of fish pass through a door but without certainty that each and every fish has passed through once per measurement cycle 2.
  • Active mode Each and every fish passes through a door once per measurement cycle
  • Uni-directional - fish may only pass through a door in a specified direction and may not pass in the opposite direction
  • passive mode one obtains data on a large sample of fish but without certainty that one has examined each fish one time.
  • the sample may be larger or smaller than the population.
  • One may not obtain a count of the fish in this mode but it is useful for obtaining better statistics for, for example, biomass, growth rate, parasite load, etc and for parasite removal.
  • measurements are number, weight, size distribution and growth rate.
  • information about the weight of each fish can be used to calculate biomass, size distribution and growth rate in the facility.
  • Another purpose of the invention is to facilitate timely detection of loss of fish from the facility. Examples of loss mechanisms are death due to sickness, death due to predators, or escape due to damage to the cage structure.
  • Another purpose of the invention is to reduce labor costs in a facility by providing a context for automating some operations. Examples of operations that may be automated are vaccination of fish by injection and inspection and counting of parasite loads on the fish.
  • Another purpose of the invention is to reduce stress on the fish by avoiding pumping operations or temporary removal of fish from the water. Reduced stress on the fish is known to promote faster growth and thereby faster time to market, both of which are commercial advantages. The overall welfare of the fish is improved.

  • Both walls 305 and 306 are made of flexible material such as cage netting which can accommodate dimensional variations in the main facility. This structure is suitable for active mode operation where the wall 305 is slowly rotated about axis 304.
  • One end of vertical wall 305 is attached to the outer perimeter with a sliding contact 308 such that it may be moved along the perimeter to change the angle between the walls.

  • the uni-directional openings are arranged such that a fish may freely traverse the entire volume of the facility freely but only in the specified direction and sequence selected by the operator.
  • the uni-directional openings may be formed in a variety of ways. The simplest form is a truncated conical shaped structure with a larger diameter at the entrance and a smaller diameter at the exit end. This form is well-known from fish traps where all the conical openings point inward into the trap. In the present invention, the conical openings point in the same direction allowing the fish to swim from one sub-volume to another.

  • a third form is a set of elastic fingers in a roughly conical shape which the fish can swim through with little effort but cannot swim against. This third form is also well-known and commercially available.
  • a fourth form consists of a short passage or tunnel integrated with a fish sensor. When a fish enters the tunnel, the sensor detects its presence and causes an entrance door to close behind the fish. After the fish has exited the passage, an exit door is closed and the entrance door is opened again. The inventor has tested such a design in a 3m diameter seawater aquaculture facility which was divided into two sub-volumes by means of vertical netting walls to create a 90 degree segment and a 270 degree segment.
  • Each of the two walls contained a single uni-directional opening in the form of a conical opening, also formed of netting material.
  • Such conical openings are the simplest form of a uni- direcitonal opening.
  • the test facility contained 50 juvenile salmon. The behavior of the fish was recorded by video monitoring. We observed that the fish readily adapted to the presence of the walls within a few hours and swam through the unidirectional openings in the intended direction. No fish swam in the 'wrong' direction through the conical openings. All fish were observed to swim freely through both walls several times per hour within the first 12 hours after encountering the structure for the first time.

  • CWT 'coded wire tag'
  • Fish may also be individually identified by external markings, either naturally occurring or artificially applied such as, for example, fin clipping and cold branding. These techniques are useful in research involving hundreds or, perhaps, thousands of fish. They are not practical or cost-effective for high-volume, commercial cage based aquaculture with several tens of thousands or hundreds of thousands of fish.
  • the other alternative is to cause the fish to systematically move from one location to another and to count, measure or treat the fish during the transfer.
  • This may be referred to as active operation of the invention.
  • active mode the fish are motivated to move from one sub-volume to another. This is conceptually similar to pumping the fish from one location to another but is substantially different in the present invention in that a) the time scale is much slower and b) the fish have some control over when they will swim through the system and thereby less stress.
  • fish are forcibly transferred from one location to another in connection with, for example, transporting young fish from a land based facility to a sea-based facility, collecting adult fish that are ready for harvest for transport to the processing plant, or temporarily transporting fish from a sea-based cage to a well- boat for pharmaceutical treatment and then transporting them back to the sea-cage.
  • the most common method of forcing the fish from one place to another in current practice is by use of fish pumps which is stressful for the fish.
  • the emphasis in current operations is to accomplish such transfers as quickly as possible consistent with safe transport of the fish. In the invention, this movement is intentionally much slower, occurring over the course of several days.
  • the fish we arrange for the fish to move from one sub-volume to another within the same aquaculture facility where at least one sub-volume is initially empty and the sub- volumes that initially have fish are finally empty.
  • the current invention is an improvement over current practice in the context of large-scale, commercial aquaculture facilities. It is better because a) movement of fish from one location to another is not forced and therefore not stressful for the fish, b) the transfer is done "in place" (i.e. within the same aquaculture cage) and therefore does not require the cost of a pumping system or a well-boat, c) it is not necessary to use more volume than necessary to hold the original population (i.e. it is not necessary to have twice the needed volume with associated costs as in other systems) and d) is compatible with automatic measurement and treatment operations that can be conducted underwater which again is less stressful for the fish and less costly for operators compared to conducting such operations manually. Examples of operations that can be performed underwater in combination with the present invention are vaccination, counting or removal of parasites or sorting of fish for harvesting.
  • the method used to motivate the fish to move from one sub-volume to another in active operation is to slowly (i.e. imperceptibly to the fish) change the geometry of the sub-volumes so that the fish gradually experience that the density of fish in a sub-volume is increasing.
  • the fish will be motivated to leave a sub-volume when the density becomes too high. It is important that this happens very slowly so that the fish are unaware of the changing geometry. In practice, this means that the change will happen on a timescale of days for a full-scale commercial facility.
  • One purpose of the invention is to combine existing or future measurement methods with the uni-directional openings so that each fish may be counted, measured, treated if desired and or sorted for special handling.
  • a large aquaculture cage for salmon in Norway may contain by law no more than a "maximum allowed biomass" (MAB) of fish. In certain areas this limit is 780 metric tons An adult salmon weighs about 5kg so the MAB is equivalent to 156 000 mature salmon.
  • MAB maximum allowed biomass
  • an operator may wish to count, measure or inspect all fish in the facility each week. In active mode, the changing size of a sub-volume over the course of a week will be imperceptible to the fish and thus not stressful.
  • the growth rate of some external parasites such as salmon lice is longer than 1 week so that continuous inspection and removal over this time period will prevent the formation of adult parasites.
  • all fish in such a facility may be processed in the course of a week using a single uni-directional opening with associated apparatus and allowing 3.88 seconds per fish for treatment. This is enough time to count and measure the size of each fish using a "biomass frame" as it passes through the opening. All fish in such a facility may be processed in the course of a week using two uni-directional openings and associated apparatus and allowing 7.75 seconds per fish for measurement and treatment. Similarly, the same could be accomplished with three uni-directional openings and associated apparatus and allowing 11.6 seconds per fish for measurement and treatment. There is a tradeoff on measurement speed vs investment in multiple sets of measurement equipment.
  • the disclosed system and method is reasonably scalable to full- scale commercial aquaculture facilities using one or several uni-directional openings in the wall of a sub-volume.
  • An important aspect of the invention is the design of the uni-directional openings. Some such openings are well known and used in the design of fish traps. In a fish trap, all the uni-directional openings point inwards. In the invention, the unidirectional openings are oriented such that the fish can swim from one sub-volume to another in a sequence dictated by the orientation of the openings. Uni-directional openings that are already known and can be used with this invention include
  • a short passage with hinged door at each end which are controlled by the presence of a fish in the passage such that the fish may be detained in the passage for a duration necessary for inspection, measurement or treatment.
  • the entrance door can remain open until a fish enters the passage.
  • the presence of the fish is detected by an appropriate electronic, acoustic or optical sensor which causes the entrance door to close. After the desired duration, the exit door opens allowing the fish to leave the passage.
  • fish may be directed to different sub-volumes by opening different exit doors in response to the result of a particular measurement.
  • An opening with any type of door combined with a visual element such as a colored border or active lighting around the entrance to the opening to allow the fish to more easily locate the opening.
  • the invention system and method are compatible with current feeding practice in large aquaculture facilities when the sub-volumes are defined by vertical walls. This is most commonly done by means of automatic feeders which disperse food over the surface of the cage area. Each sub-volume will then receive the same amount of feed as in an undivided cage. When feeding is accomplished by point feeders, each sub-volume must have such a feeder. When feeding is accomplished by means of an apetite controlled feeder, the appetite controlled feeder may be placed in the center of the cage and subdivided in the same way as the whole cage. In all cases, fish may eat in the same way as they were accustomed to eat in an undivided cage.

  • the fixed wall contains one or more uni-directional openings. All fish are initially in a single sub-volume which occupies substantially the entire facility volume. As the movable wall is rotated and the initial sub-volume decreases, fish will pass through the uni-directional openings into the second increasing sub-volume. The fish may be counted, measured, inspected or treated during their passage through the unidirectional openings. When the movable wall has rotated fully, the initial sub-volume has substantially zero volume while the second sub-volume occupies substantially the entire facility volume. With this method, every single fish in the facility is evaluated.

Abstract

L'invention concerne un système à des fins d'utilisation dans une installation d'aquaculture comportant un casier d'aquaculture (301) ayant un volume intérieur subdivisé en deux sous-volumes ou plus (302, 303) par un ou plusieurs séparateurs (305, 306). Au moins un séparateur (306) a une ou plusieurs ouvertures unidirectionnelles (307) en communication avec un sous-volume contigu, lesdites ouvertures permettant aux poissons de passer d'un sous-volume (303) à un sous-volume adjacent (302) dans une seule direction. Dans un mode de réalisation, l'un des diviseurs est une cloison mobile (305) qui tourne autour d'un axe central (304), pour ainsi réduire le volume d'un sous-volume (303) contenant tous les poissons de l'installation progressivement jusqu'à environ zéro, ceci amenant chaque poisson dans le sous-volume (303) à nager au travers des ouvertures unidirectionnelles (307) jusqu'à un sous-volume adjacent (302). Des dispositifs servant à mesurer, à épouiller et/ou vacciner les poissons sont agencés en connexion avec les ouvertures (307).
