Description
Den foreliggende oppfinnelse vedrører en oppdrettsmær for fisk eller sjødyr, omfattende en bærende konstruksjon som er anordnet ved sjøoverflaten, og som en notduk er festet til for dannelse en én eller flere notposer som utgjør én eller flere oppholdssoner under vann for fisken. The present invention relates to a breeding platform for fish or marine animals, comprising a supporting structure which is arranged at the sea surface, and to which a net cloth is attached to form one or more net bags which constitute one or more underwater residence zones for the fish.
Slike oppdrettsmærer krever vedlikehold og ettersyn uansett hvordan den bærende konstruksjon er utformet. Such breeding beds require maintenance and inspection regardless of how the supporting structure is designed.
Fordi de fleste anlegg ligger i sjøen, vil notlinet eller notduken bli begrodd, og dersom notposene ikke blir skiftet eller fornyet, vil maskene i noten gro fullstendig igjen. Det hindrer vanngjennomstrømning i fiskenes oppholdssoner og konsekvensene kan være oksygenmangel hos fisken, Because most facilities are located in the sea, the seine line or seine cloth will become fouled, and if the seine bags are not replaced or renewed, the meshes in the seine will grow completely again. It prevents water flow in the fish's living areas and the consequences can be a lack of oxygen in the fish,
som kan føre til sykdom og/eller fiskedød. which can lead to disease and/or fish death.
Et middel for å redusere begroingen av notduken, går ut på impregnering av duken med forskjellige kjemiske forbindelser. Impregneringen utgjør en betydelig kostnad for oppdrette-ren samtidig som de kjemiske forbindelser som forhindrer alge-vekst, i enkelte tilfeller kan medføre miljøforringelse for fisken. One means of reducing the fouling of the net cloth consists of impregnating the cloth with various chemical compounds. The impregnation represents a significant cost for the breeder at the same time that the chemical compounds that prevent algae growth can in some cases lead to environmental degradation for the fish.
Et annet middel for å holde posene rene går ut på å skifte notposene med visse mellomrom. Skifting av notposer i dagens mærsystemer er imidlertid meget arbeidskrevende og medfører stress for fisken, fordi denne må flyttes over i en annen pose under vaskeprosessen. Dette gir tap i form av økt arbeidskraftbehov, tapt effektivitet og redusert produksjon i anlegget. Another way to keep the bags clean is to change the mesh bags at certain intervals. However, changing net bags in today's mare systems is very labor-intensive and causes stress for the fish, because it has to be moved into another bag during the washing process. This results in losses in the form of increased labor requirements, lost efficiency and reduced production in the plant.
Til grunn for den foreliggende oppfinnelse ligger den oppgave å råde bot på de ovenfor omtalte ulemper. The present invention is based on the task of remedying the disadvantages mentioned above.
Hensikten oppnås ved en oppdrettsmær av den innlednings-vis angitte art som ifølge oppfinnelsen er de trekk som fremgår av kravene. The purpose is achieved by a rearing mare of the kind indicated at the outset which, according to the invention, has the features that appear in the claims.
Med den nye mærtype unngår man det ovenfor nevnte pro-blem med at posene blir begrodd, idet notduken i posene vaskes etter behov. Fortrinnsvis kan utskiftningsorganene omfatte en første og en annen notrull anordnet ved hver sin ende av mæren, idet notrullene tjener til vekselvis inn- og utspoling av notduk langs området for fiskens oppholdssoner. Notrullene kan drives ved hjelp av motor- eller bølgekraft, og drivkraf- With the new mesh type, the above-mentioned problem of the bags becoming fouled is avoided, as the net fabric in the bags is washed as needed. Preferably, the replacement members can comprise a first and a second grooved roller arranged at each end of the net, the grooved rollers serving to alternately wind in and out the grooved fabric along the area where the fish stay. The groove rollers can be driven using motor or wave power, and drive power
ten kan styres manuelt eller automatisk. can be controlled manually or automatically.
I områdene for notposene, dvs. oppholdssonene for fisken, er der anordnet justerbare lederorganer for regulering av posedybden og føring av notduken mellom utskiftningsorganene. Ledeorganene kan være montert noe ettergivende for utjevning av spenninger i notposene, samtidig som de er utført med individuelle justeringsorganer. En slik mekanisme gjør det lettvint å skifte notduken uten at fisken må flyttes over i en ny pose, samtidig som konstruksjonen omfatter rengjørings-organer for notduken, fortrinnsvis i området for notrullene. In the areas for the seine bags, i.e. the stay zones for the fish, there are adjustable guide members for regulating the bag depth and guiding the seine cloth between the replacement members. The guide members can be mounted somewhat loosely to equalize tensions in the groove bags, at the same time they are made with individual adjustment members. Such a mechanism makes it easy to change the net cloth without the fish having to be moved into a new bag, while the construction includes cleaning means for the net cloth, preferably in the area of the net rolls.
I det samme område kan der være anordnet pppsamlingsorganer for det avfall som notduken renses for. In the same area, there can be arranged ppp collection bodies for the waste that the net cloth is cleaned of.
Konstruksjonen kan være slik at noten kan trekkes fra den ene til den annen side av anlegget med en hastighet av 2-3 m/time. I bunnen av noten kan der monteres medbringere som tjener til å fjerne død fisk fra notbunneh. Under rullene kan der monteres dyser som hele tiden spyler noten ren. The construction can be such that the net can be pulled from one side of the plant to the other at a speed of 2-3 m/hour. At the bottom of the net, catchers can be mounted which serve to remove dead fish from the bottom of the net. Under the rollers, nozzles can be fitted that constantly flush the groove clean.
Fortrinnsvis er den utskiftbare notduk anordnet i en bærende konstruksjon som utgjør en flytende enhet med passende adkomstveier rundt de enkelte notposer. Det er da viktig at gangbaner og utforingsplasser er gjort brede, slik at det er mulig å benytte spesielle foringsvogner. Det bidrar til et bedre arbeidsmiljø og en tryggere arbeidsplass. Preferably, the replaceable net cloth is arranged in a load-bearing structure which forms a floating unit with suitable access routes around the individual net bags. It is therefore important that walkways and loading areas are made wide, so that it is possible to use special loading wagons. It contributes to a better working environment and a safer workplace.
Oppfinnelsen vil i det følgende bli beskrevet nærmere under henvisning til tegningen som viser et utførelseseksempel på oppdrettsmæren ifølge den foreliggende oppfinnelse. In the following, the invention will be described in more detail with reference to the drawing which shows an exemplary embodiment of the breeding mare according to the present invention.

Den bærende konstruksjon omfatter et flyteelement omfattende en flerhet av pongtonger 1, som har form av rør og ved hver ende er utformet med baugprofil. Til pongtongene er der sveiset tette vegger 2 av plater som sammen med pongtongene 1 rager ca. 1,25 m under vannoverflaten 2a. The supporting structure comprises a floating element comprising a plurality of pontoons 1, which have the shape of a tube and are designed with a bow profile at each end. Tight walls 2 of plates are welded to the pontoons, which together with the pontoons 1 protrude approx. 1.25 m below the water surface 2a.
Innenfor området som er inngrenset av pongtongene 1 Within the area bounded by the pontoons 1
og veggene 2, er der utspent en notduk 4 for dannelse av to notposer 4a og 4b, idet notduken 4 er spesialkonstruert for å tåle strekkbelastninger og for å sikre god gjennomstrømning gjennom notposene eller oppholdssonene for fisken 2b. and the walls 2, a net cloth 4 is stretched out to form two net bags 4a and 4b, the net cloth 4 being specially designed to withstand tensile loads and to ensure good flow through the net bags or the fish's residence zones 2b.
For at noten skal kunne gjøres ren eller skiftes uten So that the note can be cleaned or replaced without it
at fisken må flyttes over i en ny pose, er der ved hver ende av konstruksjonen montert organer som kan forflytte noten 4 samtidig som notposene 4a og 4b holdes intakt uten å for-styrre fiskene 2b. Utskiftningsorganene er ved det viste ut-førelseseksempel utformet som nettruller eller notruller 5 anordnet ved hver ende av mæren, idet notrullene 5 tjener til vekselvis inn- og utspoling av notduk langs området for fiskens oppholdssoner. Når notrullene 5 dreier seg, vil der opp-stå et strekk i notduken. For å holde notduken 4 på plass, slik at den danner passende notposer 4a og 4b, er der montert lederuller 6 som kan være fjærbelastet via sleidestenger 7, idet lengden av stengene 7 kan justeres for regulering av posedybden, samtidig som den ettergivende montering utjevner spenninger i nettposene 4a, 4b. Passende kan notduken 4 være felt ut på de steder hvor man forventer at belastningen er størst. that the fish must be moved into a new bag, at each end of the structure there are mounted organs that can move the seine 4 while keeping the seine bags 4a and 4b intact without disturbing the fish 2b. In the embodiment shown, the replacement members are designed as net rollers or grooved rollers 5 arranged at each end of the net, the grooved rollers 5 serving to alternately wind in and out the grooved fabric along the area where the fish stay. When the grooved rollers 5 turn, there will be a stretch in the grooved fabric. In order to keep the groove cloth 4 in place, so that it forms suitable groove pockets 4a and 4b, guide rollers 6 are mounted which can be spring-loaded via slide rods 7, as the length of the rods 7 can be adjusted to regulate the pocket depth, at the same time that the flexible assembly equalizes tensions in the net bags 4a, 4b. Appropriately, the corrugated sheet 4 can be laid out in the places where the load is expected to be greatest.
Ved den viste utførelsesform er konstruksjonen utformet slik at notrullene 5 skal kunne betjene to poser eller mærer 4a og 4b. For å sikre at notduken 4 ikke skal skades under bevegelse samtidig som den holdes på plass, er der montert ytterligere øvre lederuller 10 og 11, samtidig som der i området mellom notposene 4a og 4b er anordnet en ytterligere valse 12 som tjener til å ivareta disse funksjoner. Ved sine øvre kanter er notduken forsterket med telne 15, som på sin side står i forbindelse med de nevnte lederuller 10. In the embodiment shown, the construction is designed so that the grooved rollers 5 can operate two bags or meters 4a and 4b. In order to ensure that the corrugated cloth 4 is not damaged during movement while it is held in place, further upper guide rollers 10 and 11 are mounted, while in the area between the corrugated bags 4a and 4b a further roller 12 is arranged which serves to take care of these functions. At its upper edges, the corrugated sheet is reinforced with telne 15, which in turn is connected to the aforementioned guide rollers 10.
