Description
Oppfinnelsens område Field of the invention
Den foreliggende oppfinnelse vedrører en fremgangsmåte og en anordning for å immobilisere marine organismer, så som fisk, i vann. Oppfinnelsen gjelder også anvendelse av fremgangsmåten og anordningen The present invention relates to a method and a device for immobilizing marine organisms, such as fish, in water. The invention also applies to the use of the method and the device
Med marine organismer menes hovedsakelig fisk og foreliggende omtale av den oppfinneriske behandling skal videre omtales og beskrives i forbindelse med fisk. By marine organisms is meant mainly fish and the present discussion of the inventive treatment shall be further discussed and described in connection with fish.
Med immobilisering menes at man ønsker å roe ned fiskens bevegelser slik at den holdes helt i ro, eller kun beveger seg helt minimalt. Dette er aktuelt nå den skal underkastes ulike behandlinger, noe som det er behov for både for håndtering av såkalt villfisk og av oppdrettsfisk. Eksempel på forhold hvor det er behov for å roe ned fisk, er som en innledning når den for eksempel fremføres i en slaktelinje eller skal telles for å få oversikt over antallet fisk i et avlukke så som en oppdrettsmerd, eller den eksempelvis skal vaksineres, eller behandles for å fjerne lus. Andre settinger hvor fisk må roes ned for ulike behandlinger kan også tenkes. Immobilization means that you want to calm down the fish's movements so that it is kept completely still, or only moves minimally. This is relevant now that it is to be subjected to various treatments, which is needed both for the handling of so-called wild fish and of farmed fish. Examples of conditions where there is a need to calm fish down are as an introduction when, for example, it is brought forward in a slaughter line or is to be counted to get an overview of the number of fish in a cubicle such as a breeding pen, or it is to be vaccinated, for example, or treated to remove lice. Other settings where fish must be tranquilized for various treatments can also be imagined.
Oppfinnelsens bakgrunn. The background of the invention.
Når det gjelder en praktisk håndtering av fisk, og som leder til foreliggende oppfinnelse, skal det vises til hva som kjennes fra norsk patent NO-342.294. Her omtales det et instrument for behandling av en og en fisk ad gangen fra en større ansamling av fisk. For behandlingen (eks. vaksinering og lusefjerning etc.) føres en og en fisk fra den større populasjonen, inn gjennom et gradvis avsmalnende rør frem til selve be-handlingskammeret. I dette kammeret forminskes fiskens frie rom ved at den trenges sammen av plateformer som skyves fram mot fisken slik at den blir stående helt i ro slik at behandlingen kan foregå så presist som mulig. Etter behandlingen opphører sammentrengningen og en utløpsport åpner slik at fisken kan slippes ut fra trengsel-kammeret. When it comes to the practical handling of fish, and which leads to the present invention, reference should be made to what is known from Norwegian patent NO-342,294. An instrument for treating one fish at a time from a larger collection of fish is described here. For the treatment (e.g. vaccination and lice removal etc.), one fish at a time from the larger population is brought in through a gradually narrowing tube to the treatment chamber itself. In this chamber, the fish's free space is reduced by being compressed by plates that are pushed forward towards the fish so that it remains completely still so that the treatment can take place as precisely as possible. After the treatment, the constriction ceases and an outlet port opens so that the fish can be released from the crowding chamber.
Det viser seg imidlertid at fisken fortsatt kan være så urolig og spreller i den trengte posisjonen at behandlingen blir upresis og forvanskes. Det er derfor ønskelig å frembringe en ny metode og instrumentering for å forbedre immobiliseringen ifølge oppfinnelsen. Ikke bare til bruk i metoden ifølge ovennevnte patent, men til alle andre behandlinger av fisk hvor det er viktig at den holdes immobil. However, it turns out that the fish can still be so restless and splash in the needed position that the treatment becomes imprecise and distorted. It is therefore desirable to produce a new method and instrumentation to improve the immobilization according to the invention. Not only for use in the method according to the above-mentioned patent, but for all other treatments of fish where it is important that it is kept immobile.
Det er kjent tidligere bruk av lys for å påvirke adferden til fisk. Eksempelvis er det kjent at fisk normalt vil unngå lys og vike/svømme unna for en slik påvirkning. Det har nå vist seg lys likevel kan benyttes til å oppnå dette formålet, å immobilisere fisken, ved at påvirkningen med lys skjer på en helt spesiell måte. The previous use of light to influence the behavior of fish is known. For example, it is known that fish will normally avoid light and shy away/swim away from such an influence. It has now been shown that light can nevertheless be used to achieve this purpose, to immobilize the fish, by the effect of light occurring in a very special way.
Formål med foreliggende oppfinnelse. Purpose of the present invention.
Det er et formål med foreliggende oppfinnelse å frembringe en ny metode til å holde fisk immobilisert, eksempel når den befinner seg i en vannmasse eller når den fremføres langs en transportrenne for eksempel til slakting. It is an object of the present invention to produce a new method for keeping fish immobilized, for example when it is in a body of water or when it is moved along a transport chute, for example for slaughter.
Oppsummering av oppfinnelsen Summary of the invention
Fremgangsmåten ifølge oppfinnelsen er kjennetegnet ved at fisken utsettes for blinkende lys fra en lyskilde. Videre anvendes det en lysblink-kilde som kan tenne og slukke lyset i et gitt mønster eller en frekvens. Samt at det foretrekkes at blinkefrekvensen (tenning / slukking) til lyset er i størrelsesorden 1 - 20 lysblink pr. sekund. The method according to the invention is characterized by exposing the fish to flashing light from a light source. Furthermore, a flashing light source is used which can switch the light on and off in a given pattern or frequency. And that it is preferred that the flashing frequency (switching on / off) of the light is in the order of 1 - 20 light flashes per second. second.
Ifølge en foretrukket utførelse behandles fisken i en fremføringslinje i form av et hullegeme formet avlukke hvor innsiden av legemet er utstyrt med et antall lyskilder som kan påvirke fisken med lysblink. According to a preferred embodiment, the fish is processed in a feed line in the form of a hollow body-shaped cubicle where the inside of the body is equipped with a number of light sources that can affect the fish with flashes of light.
De ytterligere foretrukne utførelsene av oppfinnelsen framgår av de uselvstendige kravene 5 -13. The further preferred embodiments of the invention appear from the independent claims 5-13.
Anordningen ifølge oppfinnelsen er kjennetegnet ved de trekk som framgår av karakteristikken i krav 14, samt i de uselvstendige kravene 15 - 17. The device according to the invention is characterized by the features that appear in the characteristic in claim 14, as well as in the independent claims 15 - 17.
Anvendelsene av oppfinnelsen framgår av krav 18. The applications of the invention appear from claim 18.
Ved oppfinnelsen har man altså funnet at det er meget gunstig å benyttes synlig lys, som fisken utsettes for i form av pulser. Det betyr at lyset blinker av og på med høy blinkefrekvens eller i en annen av/på-sekvens. Fortrinnsvis benyttes det et stroboskop-instrument for å oppnå en slikt lysblinkeregime. Det har vist seg at fisken blir helt paralysert av denne påvirkningen og blir stående/liggende helt i ro. Denne nye oppfinneriske metoden er allerede tatt i bruk i forbindelse med apparatet som beskrives i nevnte NO-342.294. En vesentlig valgfri variant er at med foreliggende oppfinnelse, kan lysblinkpåvirkingen ifølge nevnte patent erstatte de fortrengningsrammene som patentet beskriver, og som skal skyves innover mot fiske for å gjøre det trangere for den for deretter å trekkes tilbake når behandlingen er avsluttet og fisken skal fremføres videre i behandlingen. With the invention, it has thus been found that it is very beneficial to use visible light, which the fish are exposed to in the form of pulses. This means that the light flashes on and off with a high flashing frequency or in a different on/off sequence. Preferably, a stroboscope instrument is used to achieve such a light flashing regime. It has been shown that the fish is completely paralyzed by this effect and remains standing/lying completely still. This new inventive method has already been put into use in connection with the apparatus described in the aforementioned NO-342,294. An essentially optional variant is that with the present invention, the light flashing effect according to the aforementioned patent can replace the displacement frames that the patent describes, which must be pushed inwards towards the fish to make it tighter for it and then be withdrawn when the treatment is finished and the fish must be moved forward in the treatment.
Ved foreliggende oppfinnelse benyttes det synlig lys som er form for elektromagnetisk stråling. Synlig lys forårsaker gitte synsinntrykk i et fiskeøye. Det synlige spektrum ligger innenfor bølgelengder på mellom 380–750 nm. In the present invention, visible light is used, which is a form of electromagnetic radiation. Visible light causes given visual impressions in a fish eye. The visible spectrum lies within wavelengths between 380–750 nm.
For å frembringe lysblink, benyttes det fortrinnsvis en lysblink-kilde som kan tenne og slukke lyset i et gitt mønster eller en frekvens. Tenne og slukkefrekvensen kan ligger fortrinnsvis på 1 - 20 blink pr. sekund. Innenfor denne frekvensen vil fisken oppfatte lysblinkene og bli paralysert av det og dermed roes fisken helt. Lyset er fortrinnsvis et hvitt lys, selv om lys med ulike fargetoner – eks: gult-rødt-blått eller grønt – også kan anvendes. To produce light flashes, a light flash source is preferably used which can turn the light on and off in a given pattern or frequency. The switch-on and switch-off frequency can preferably be 1 - 20 flashes per second. Within this frequency, the fish will perceive the flashes of light and be paralyzed by it, thus calming the fish completely. The light is preferably a white light, although light with different color tones - eg: yellow-red-blue or green - can also be used.
Særlig foretrukket er det å benytte en stroboskopteknologi for å frembringe lysblink. Et stroboskop er et instrument som deler lyset opp i lysglimt (lynblink) idet stroboskopteknologien er velkjent og ikke trenger å beskrives mere detaljert her. It is particularly preferred to use a stroboscope technology to produce light flashes. A stroboscope is an instrument that divides the light into flashes of light (lightning flashes), as the stroboscope technology is well known and does not need to be described in more detail here.
Ifølge oppfinnelsen anvendes fremgangsmåten og anordningen for håndtering av oppdrettsfisk, hvor fisken føres gjennom en linje i et telleapparat, den skal vaksineres, eller det tas prøver av fisken, fjerning for lus fra fisken, eller generelt overføring av fiske gjennom et transportsystem, som angitt i krav 18. According to the invention, the method and device for handling farmed fish is used, where the fish is passed through a line in a counting device, it is to be vaccinated, or samples are taken of the fish, removal of lice from the fish, or generally transfer of fish through a transport system, as indicated in requirement 18.
Beskrivelse av figurer Description of figures
Foretrukne utførelser av oppfinnelsen skal i det etterfølgende omtales mer detaljert med henvisning til de medfølgende figurene, hvori: Preferred embodiments of the invention will be described in more detail below with reference to the accompanying figures, in which:
Figur 1 viser et eksempel på behandling (lusfjerning/vaksinering) av en og en fisk i en ansamling av fisk. Figure 1 shows an example of treatment (lice removal/vaccination) of individual fish in an accumulation of fish.
Figur 2 viser en forstørret tegning av behandlingskammeret hvor en og en fisk holdes i ro. Figure 2 shows an enlarged drawing of the treatment chamber where each fish is kept at rest.
Figur 3 viser en ansamling av et større antall fisk i en beholder eller et forkammer, hvor fisken utsettes for lyspulser som ifølge oppfinnelsen for eventuelt å roe den ned før den skal føres videre i et trangere behandlingsrør - en for en – som på figur 1. Figure 3 shows an accumulation of a large number of fish in a container or an antechamber, where the fish are exposed to light pulses which, according to the invention, possibly calm them down before they are taken further into a narrower treatment tube - one by one - as in Figure 1.
Beskrivelse av foretrukne utførelser av oppfinnelsen. Description of preferred embodiments of the invention.
Oppfinnelsen skal nå forklares mer detaljert med henvisning til figur 1 som viser en situasjon hvor en og en fisk i vann 17 føres fremover langs en behandlingsbane i et behandlingsanlegg 10, og fra et forkammer 12 med flere fisk 16 til et avsmalnet rørformet behandlingskammer 14 hvor det kun er plass til en eneste fisk 16. The invention will now be explained in more detail with reference to Figure 1, which shows a situation where one fish in water 17 is led forward along a treatment path in a treatment facility 10, and from a pre-chamber 12 with several fish 16 to a tapered tubular treatment chamber 14 where the there is only room for a single fish 16.
I behandlingskammer 14 skal den ene fisken 16 stå mest mulig i ro, ved hjelp av oppfinnelsen. In the treatment chamber 14, the one fish 16 must stand still as much as possible, with the help of the invention.
Fisken 16 kan på forhånd være trengt sammen i kammeret 14 ved hjelp av ikke viste mekaniske sammentrengingsorganer som ikke skal beskrives her – noe som egentlig ikke er nødvendig siden lysblink alene kan immobilisere og paralysere fisken. Fisken står i utgangspunktet ganske immobilisert i røret, og man ønsker enda sterkere immobilisering ved at den utsettes for kraftige sterke lysblink som ifølge oppfinnelsen. Innsiden av behandlingskammeret 14 er utstyrt med et antall lyskastere 20, plassert med innbyrdes avstand rundt hele rørets innervegg. Lyskasterne kan belyse fisken med lysstråler antydet ved 22 på figurene. Lyskasterne 20 er, se figur 2, tilkoplet en ikke vist strømkilde 26(K) (figur 2) via ledning 22, idet en pulsgiver 24(S) er innsatt i ledningsettet 22 for å danne lysblinkene som ifølge oppfinnelsen. Når det antall lyskastere 20 danner blinkende lys med den foran angitte frekvens inne i kammeret 14, observeres det at fisken 16 blir helt passiv og paralysert slik man ønsker for å få til en adekvat behandling av fisken i kammeret 14. The fish 16 can be compressed beforehand in the chamber 14 by means of mechanical compression means not shown which will not be described here - which is not really necessary since light flashes alone can immobilize and paralyze the fish. The fish is initially quite immobilized in the tube, and even stronger immobilization is desired by exposing it to strong bright flashes of light as according to the invention. The inside of the treatment chamber 14 is equipped with a number of spotlights 20, spaced around the entire inner wall of the tube. The spotlights can illuminate the fish with light beams indicated at 22 in the figures. The spotlights 20 are, see figure 2, connected to a power source 26(K) (figure 2) not shown, via line 22, a pulse generator 24(S) being inserted in the line set 22 to form the light flashes as according to the invention. When the number of floodlights 20 form flashing lights with the aforementioned frequency inside the chamber 14, it is observed that the fish 16 becomes completely passive and paralyzed as desired in order to achieve an adequate treatment of the fish in the chamber 14.
Et gitter 30 er vist ved innløpsenden 15 til kammeret og dette føres fremover mot høyre når fisken skal ut av kammeret 14 etter behandlingen i kammer 14. Ved utløpet fra forkammeret 12, hvorfra en og en fiske tas og føres videre til høyre, kan det også innvendig plasserte lyskastere 20 rundt den i innvendige omkretsen av kammeret 14. Lyskasterne i de to kamrene kan om ønskelig samkjøres for lettere å få fisken framført fra forkammeret 12 til behandlingskammeret 14. A grid 30 is shown at the inlet end 15 of the chamber and this is moved forward to the right when the fish is to exit the chamber 14 after processing in chamber 14. At the outlet from the antechamber 12, from which one fish at a time is taken and moved further to the right, it can also internally placed searchlights 20 around it in the inner circumference of the chamber 14. The searchlights in the two chambers can, if desired, be moved together to more easily get the fish forward from the antechamber 12 to the treatment chamber 14.
Dette å utsette fisken for kraftige lysblink, har også virkning på den når fisken sklir fremover en tørr renne frem til en slaktebenk. Lysblinkene gjør at fisken roer seg kraftig og blir paralysert og ikke stresser seg. Dette viser at oppfinnelsen kan brukes og ha virkning på fisk i vann og på «land». Exposing the fish to strong flashes of light also has an effect on it when the fish slides forward down a dry chute to a slaughter bench. The light flashes cause the fish to calm down strongly and become paralyzed and not stress. This shows that the invention can be used and have an effect on fish in water and on "land".
Figur 3 viser en avlukket beholder 40 hvor en større mengde fisk 16 er ansamlet. Dette kan være samme kammer som forkammeret 12. Rundt innvendig i kammeret 40 er det montert lyskastere 20 av samme type som brukt i forbindelse med figurene 1 og 2. Disse lyskasterne kan frembringe lysblink som beskrevet. Praktiske forsøk har vist at fisken 16 i vannmassen 17 ble betraktelig roligere i sine bevegelser i vannmassen 17 enn uten slik lysblink-påvirkning. Denne beholderen kan være det forkammeret 12 som er beskrevet i forbindelse med figurene 1 og 2. Figure 3 shows an enclosed container 40 in which a large amount of fish 16 has accumulated. This can be the same chamber as the antechamber 12. Around the inside of the chamber 40 are mounted spotlights 20 of the same type as used in connection with figures 1 and 2. These spotlights can produce light flashes as described. Practical tests have shown that the fish 16 in the body of water 17 became considerably calmer in its movements in the body of water 17 than without such light flashing influence. This container can be the antechamber 12 which is described in connection with Figures 1 and 2.
Praktisk forsøk har vist at man kan veksle mellom vanlig permanent belysning 22 fra lyskasterne 20 og blink(strobe)lys for å roe ned fisken, idet de vanlige permanente lysene enkelt kan omsjaltes til strobelys når man ønsker å roe ned fisken. Det er ikke særskilte eller spesielle frekvenser eller farger man bruker på blinklysene annet at det bør være tilpasset til antallet fisk 16 i vannmassen 17, det kommer an på hvor tett lysene 20 er plassert i innerveggen, og hvor tett fisken 16 står i vannmassen 17etc. Hvor tett fisken står, og hvor klart vann det er har betydning. Desto mer grumset vann, desto tettere og/eller sterkere lys trenges for å oppnå den tilsiktede virkning. Practical experiments have shown that you can switch between normal permanent lighting 22 from the spotlights 20 and flashing (strobe) lights to calm the fish down, as the normal permanent lights can easily be switched to strobe lights when you want to calm down the fish. There are no specific or particular frequencies or colors used on the flashing lights, other than that it should be adapted to the number of fish 16 in the body of water 17, it depends on how close the lights 20 are placed in the inner wall, and how close the fish 16 are in the body of water 17 etc. How closely the fish stand and how clear the water is matters. The more cloudy the water, the denser and/or stronger light is needed to achieve the intended effect.
Generelt er antallet innvendige lyskilder tilpasset til hul-legemets volum, antallet fisk i volumet samt siktbarheten (renheten) til vannet som fisken er i. Det anvendes et økende antall lyskilder i takt med økningen i vannvolumet, antallet fisk samt en redusert siktbarhet (mere grums) i vannet. Videre vil også lyskildenes (lampenes) lysstyrke økes i takt med økningen i vannvolumet, antallet fisk i tanken 12 samt en redusert siktbarhet i vannet. Desto mere partikler og grums som er i vannet, så sikten er redusert, desto sterkere lysstyrke trenges. In general, the number of internal light sources is adapted to the volume of the hollow body, the number of fish in the volume and the visibility (purity) of the water in which the fish are. An increasing number of light sources are used in line with the increase in the water volume, the number of fish and a reduced visibility (more turbidity ) in the water. Furthermore, the brightness of the light sources (lamps) will also be increased in line with the increase in the volume of water, the number of fish in the tank 12 and a reduced visibility in the water. The more particles and mud that are in the water, so visibility is reduced, the stronger the brightness is needed.
Med oppfinnelsen er det altså fremkommet at fisk som utsettes for lysblink (strobelys) paralyseres slik at den står i ro når den blir berørt. Det kan brukes til alle mulige behandlinger av fisk, i slaktelinjer for eksempel, for å roe ned fisken, eller ellers i situasjoner der man trenger å roe ned fisk i en eller annen setting. With the invention, it has thus emerged that fish that are exposed to flashing lights (strobe lights) are paralyzed so that they stand still when they are touched. It can be used for all possible treatments of fish, in slaughter lines for example, to calm the fish down, or otherwise in situations where you need to calm down fish in one setting or another.
Fisk må være innesperret når man setter på strobelys. Normalt sett vil den svømme bort fra strobelys. Fish must be contained when strobe lights are switched on. Normally it will swim away from strobe lights.
