Description
Foreliggende oppfinnelse angår et oppdrettsanlegg for marine dyr, særlig fisk, omfattende en beholder med fortrinnsvis sirkulært tverrsnitt beregnet til å fylles med vann til et visst nivå. Anlegget kan være landbasert eller bestå av en tett beholder eller pose som er nedsenket i vann. The present invention relates to a breeding facility for marine animals, particularly fish, comprising a container with a preferably circular cross-section intended to be filled with water to a certain level. The facility can be land-based or consist of a sealed container or bag submerged in water.
Den største delen av de oppdrettsanlegg for konsumfisk som finnes i dag er såkalte fiskemærer, som er plassert i sjøen. Disse mærene består av en nettpose og vannet fornyes ved hjelp av den naturlige strømmen i vannet. Det er således sterke begrensninger når det gjelder lokaliseringen av slike oppdrettsanlegg, da det for det første må være tilstrekkelig sterk strøm, uten at den må være for sterk, det må ikke være for mye sjø, og det må ikke være for grunt eller for inne-stengt. Oppdrettsanlegg av denne art er en meget sterk belastning på miljøet i sjøen. Oppdrettsanleggene forurenser i meget stor grad på grunn av ekskrementer fra fisken og f6r-rester som strømmer ut i det omkringliggende vannet gjennom nettposens vegger. Fisk i fangenskap blir lett utsatt for forskjellige sykdommer og parasitter, og det brukes derfor store mengder medikamenter i forbindelse med oppdretts-næringen. Disse medikamentene gis ofte i foret, og vil spre seg i omgivelsene der medikamentene inntas av vill fisk, sjøfugl og dyr, f.eks. oter, som Jakter på fisken i mærene eller utenfor mærene. Det kan lett tenkes at det vil kunne oppstå resistente bakteriegrupper som kan medføre uoppret-telig skade i miljøet og som også kan overføres til mennesker. Fisken i de åpne mærene er dessuten utsatt for smitte fra villfisk, og for parasitter. Sterk algevekst, store forekomster av maneter og lignende kan bevirke katastrofal fiskedød i mærene. The largest part of the farming facilities for edible fish that exist today are so-called fish ponds, which are placed in the sea. These ponds consist of a net bag and the water is renewed with the help of the natural current in the water. There are thus strong limitations when it comes to the location of such breeding facilities, as firstly there must be a sufficiently strong current, without it having to be too strong, there must not be too much sea, and it must not be too shallow or too deep -closed. Farming facilities of this kind are a very heavy burden on the marine environment. The breeding facilities pollute to a very large extent due to excrement from the fish and feed residues that flow into the surrounding water through the walls of the net bag. Fish in captivity are easily exposed to various diseases and parasites, and large amounts of drugs are therefore used in connection with the farming industry. These drugs are often given in the feed, and will spread in the environment where the drugs are ingested by wild fish, seabirds and animals, e.g. otters, which hunt the fish in the marshes or outside the marshes. It is easy to imagine that resistant groups of bacteria could arise which could cause irreparable damage to the environment and which could also be transmitted to humans. The fish in the open lakes are also exposed to infection from wild fish and to parasites. Strong algae growth, large occurrences of jellyfish and the like can cause catastrophic fish deaths in the lakes.
Hensikten med foreliggende oppfinnelse er først og fremst å eliminere de ovennevnte ulempene og å optimalisere fiskeopp-drett både når det gjelder landbaserte anlegg og vannbaserte anlegg. Dette oppnås ifølge oppfinnelsen ved et oppdretts anlegg av den innledningsvis nevnte art som erkarakterisertved kombinasjonen av følgende trekk: a) at det er tilsluttet en sirkulasjonspumpe med inntak nær beholderens bunn og utløp nær vannoverflaten i beholderen, b) at det er tilsluttet tilførselsledning eller -ledninger for friskt vann og avløp for å tilveiebringe en fornyelse av The purpose of the present invention is primarily to eliminate the above-mentioned disadvantages and to optimize fish farming both in terms of land-based facilities and water-based facilities. According to the invention, this is achieved by a farming facility of the type mentioned at the outset which is characterized by the combination of the following features: a) that it is connected to a circulation pump with an intake near the bottom of the container and an outlet near the water surface in the container, b) that it is connected to a supply line or lines for fresh water and sewage to provide a renewal of
vannet over tid,the water over time,
c) at innløpet fra pumpen er rettet tangentielt eller tilnærmet tangentielt inn i beholderen for tilveiebringelse c) that the inlet from the pump is directed tangentially or nearly tangentially into the container for provision
av en konstant, sirkulerende strøm i vannet,of a constant, circulating current in the water,
d) at det i bunnen er anordnet en brønn for oppsamling av ekskrementer og forrester og andre forurensninger, og e) at det til brønnen er tilsluttet en sugeledning for fjerning av forurensningene. d) that a well is arranged at the bottom for the collection of excrement and residues and other pollutants, and e) that a suction line is connected to the well for the removal of the pollutants.
Ytterligere trekk og fordeler fremgår av de uselvstendige kravene. Further features and advantages appear in the non-independent requirements.
Ved hjelp av anlegget ifølge oppfinnelsen oppnås en rekke fordeler. For det første får man kontroll over miljøet, både i selve anlegget og det omkringliggende miljøet når det dreier seg om vannbaserte anlegg. Den stående hvirvelen i beholderen eller bassenget vil samle faste partikler sentralt ved bunnen og vil oppfanges i brønnen, hvorfra forurensningene kan transporteres bort gjennom sugeledningen. With the help of the plant according to the invention, a number of advantages are achieved. Firstly, you gain control over the environment, both in the plant itself and the surrounding environment when it comes to water-based plants. The standing vortex in the container or pool will collect solid particles centrally at the bottom and will be collected in the well, from where the contaminants can be transported away through the suction line.
Ved å sirkulere vannet gjennom en mammutpumpe vil man få en rensing av vannet. Mammutpumpen virker Jo ved at det blåses inn store mengder luft som stiger opp gjennom et vertikalt rør som bobler. Fisken opptar over gjellene surstoff fra vannet og skiller ut CO2samt urinprodukter, særlig i form av ammoniakk. Når CC^-holdige og ammoniakkholdig vann suges inn i mammutpumpen vil C02-gassen bli opptatt av de oppstigende luftboblene. Det samme vil i en viss utstrekning skje når det gjelder ammoniakk og andre stoffer. Det viktigste er imidlertid at vannet blir befridd for C02. Denne luften som strømmer inn ved overflaten i bassenget er luftanriket slik at man hele tiden får ny tilførsel av oksygenrikt vann. Vannet i oppdrettsanlegget sirkuleres således hele tiden og blir befridd for CO2og anriket med luft. Det tilføres hele tiden mindre mengder nytt vann, vesentlig for å holde ammoniakkinnholdet i vannet på et akseptabelt nivå. Ved at det bare brukes små mengder nytt vann vil det være hensikts-messig å holde en høyere temperatur i anlegget, i det minste under perioder av året. I den forbindelse kan det benyttes en varmepumpe, idet varmen i avløpsvannet og/eller varmen i det omkringliggende vannet kan utnyttes, når det dreier seg om et vannbasert anlegg. By circulating the water through a mammoth pump, the water will be purified. The mammoth pump Jo works by blowing in large quantities of air that rise up through a vertical tube that bubbles. The fish absorbs oxygen from the water via its gills and excretes CO2 and urine products, particularly in the form of ammonia. When CC^-containing and ammonia-containing water is sucked into the mammoth pump, the C02 gas will be absorbed by the rising air bubbles. The same will happen to a certain extent when it comes to ammonia and other substances. The most important thing, however, is that the water is freed of C02. This air that flows into the pool at the surface is enriched with air so that you constantly get a new supply of oxygen-rich water. The water in the breeding facility is thus constantly circulated and is freed of CO2 and enriched with air. Smaller amounts of new water are added all the time, essentially to keep the ammonia content in the water at an acceptable level. As only small amounts of new water are used, it will be appropriate to maintain a higher temperature in the plant, at least during periods of the year. In this connection, a heat pump can be used, as the heat in the waste water and/or the heat in the surrounding water can be utilized, when it is a water-based plant.
Anlegget ifølge oppfinnelsen vil dessuten egne seg meget godt som landbaserte anlegg, noe som ut fra en rekke andre forhold er meget fordelaktig. Innvendingen mot landbaserte anlegg har vært at pumping av gjennomstrømmende vann fra en nær-liggende vannkilde har vært meget energikrevende. Ved anlegget ifølge oppfinnelsen sirkulerer vannet gjennom mammutpumpen uten å kreve energi for løfting av vannet, og nytt vann tilsettes bare i små mengder og krever således liten energi. Anlegget blir helt kontrollert når det gjelder påkjenning på det ytre miljøet, og også når det gjelder påvirkning av det ytre miljøet på fisken i anlegget. The plant according to the invention will also be very well suited as a land-based plant, which is very advantageous from a number of other points of view. The objection to land-based facilities has been that pumping flowing water from a nearby water source has been very energy-intensive. In the plant according to the invention, the water circulates through the mammoth pump without requiring energy for lifting the water, and new water is only added in small quantities and thus requires little energy. The facility is fully controlled when it comes to stress on the external environment, and also when it comes to the influence of the external environment on the fish in the facility.
Når det gjelder havbaserte anlegg vil den lille mengden vann som skal til for å fornye vannet i bassenget kunne tas fra fjernereliggende steder; dersom f.eks. overflatevannet er forurenset eller for kaldt eller for varmt, kan vannet tas fra dypereliggende lag. På grunn av at det dreier seg om små vannmengder blir pumpekostnadene relativt beskjedne. In the case of sea-based facilities, the small amount of water needed to renew the water in the pool can be taken from more distant locations; if e.g. surface water is polluted or too cold or too hot, the water can be taken from deeper layers. Due to the fact that small quantities of water are involved, the pumping costs are relatively modest.
Det knytter seg helt spesielle interesser til anlegget i områder der det finnes varmt grunnvann. I et anlegg ifølge oppfinnelsen, lokalisert i et område der det er tilgang på varmt grunnvann, kan det oppdrettes konsumfisk av meget verdifulle arter som har høy pris på markedet. Det tenkes da i først rekke på stør, som betales 2-3 ganger så høyt som laks på et internasjonalt marked. Støren krever en vann-temperatur på omkring 25°C, og dette kan meget lett oppnås ved hjelp av varmt grunnvann i sydeuropeiske land der det er rik tilgang på varmt grunnvann i relativt beskjeden dybde under bakkenivået. Very special interests are attached to the plant in areas where there is warm groundwater. In a plant according to the invention, located in an area where there is access to warm groundwater, edible fish of very valuable species that command a high price on the market can be reared. Sturgeon is then primarily thought of, which is paid 2-3 times as much as salmon on an international market. The sturgeon requires a water temperature of around 25°C, and this can very easily be achieved with the help of warm groundwater in southern European countries where there is ample access to warm groundwater at a relatively modest depth below ground level.
Ifølge en videreutvikling av oppfinnelsen kan det knyttes karpedammer til anlegget. Ledningen fra den ved bunnen plasserte brønnen føres til karpedammen og det samme gjelder vann fra utløpet fra beholderen. Disse ledningene vil føre store mengder næringsstoffer til vannet i karpedammene. Karpene i en karpedam tilføres ikke for, men lever uteluk-kende på de vekstene som gror i karpedammen. For å få tilstrekkelig vekst må det tilføres store mengder næringsstoffer. Disse næringsstoffene kan ifølge oppfinnelsen nå tilføres gratis fra oppdrettsanlegget. According to a further development of the invention, carp ponds can be attached to the plant. The line from the well placed at the bottom is led to the carp pond and the same applies to water from the outlet from the container. These lines will bring large amounts of nutrients to the water in the carp ponds. The carp in a carp pond are not fed, but live exclusively on the plants that grow in the carp pond. In order to achieve sufficient growth, large amounts of nutrients must be supplied. According to the invention, these nutrients can now be supplied free of charge from the breeding facility.
Oppfinnelsen skal i det følgende forklares nærmere under hen-visning til tegningen som skjematisk viser en utførelsesform for et oppdrettsanlegg ifølge oppfinnelsen. In the following, the invention will be explained in more detail with reference to the drawing which schematically shows an embodiment of a breeding facility according to the invention.
Figur 1 viser oppdrettsanlegget sett i perspektiv med noe av veggen skåret bort, og Figure 1 shows the breeding facility seen in perspective with some of the wall cut away, and
figur 2 viser oppdrettsanlegget sett rett ovenfra. figure 2 shows the breeding facility seen from above.
Oppdrettsanlegget ifølge oppfinnelsen består av en beholder 1 med en sirkulær vegg 2 og bunn 3. Til beholderen 1 er det knyttet en mammutpumpe 4 med inntak 5 ved bunnen av beholderen 1. Utløpet 6 fra mammutpumpen er ført gjennom beholderveggen i nærheten av overflaten 7 i vannfyllingen inne i beholderen. Innløpsstussen 8 er rettet tangentielt i beholderen slik at det oppstår en hvirvlende strøm i vannet i beholderen, slik som vist med piler 9. Vannstanden i beholderen reguleres av et overløp 10. Luft til mammutpumpen blir tilført gjennom en luftledning 11 og vanntilførsel for fornyelse av vannet i beholderen er ført Inn gjennom ledninger 12. The breeding facility according to the invention consists of a container 1 with a circular wall 2 and bottom 3. A mammoth pump 4 is connected to the container 1 with an inlet 5 at the bottom of the container 1. The outlet 6 from the mammoth pump is led through the container wall near the surface 7 in the water filling inside the container. The inlet nozzle 8 is directed tangentially in the container so that a swirling current occurs in the water in the container, as shown by arrows 9. The water level in the container is regulated by an overflow 10. Air to the mammoth pump is supplied through an air line 11 and water supply for renewing the water in the container is brought in through lines 12.
I bunnen av beholderen er det anordnet en brønn 13 med en sil 14. Til brønnen 13 er det tilsluttet en sugeledning 15. A well 13 with a strainer 14 is arranged at the bottom of the container. A suction line 15 is connected to the well 13.
Ved hjelp av mammutpumpen oppnås en kontinuerlig sirkulasjon av vannet i beholderen 1. Samtidig oksygeneres vannet på grunn av luftboblingen i mammutpumpen, og vannet renses ved at CO2i vannet opptas i luftboblene som flyter opp og går ut i det fri. Gjennom tilførselsledningene fornyes vannet over tid. Vannet som tilsettes kan være oppvarmet for å holde en konstant temperatur i vannet i beholderen. Det forurensede vannet som renner ut fra beholderen gjennom overløpet 10 kan enten gå til karpedammer eller til et renseanlegg. Ledningen 15 som suger ut faste forurensninger fra brønnen 13 kan gå til opparbeidelse av gjødsel eller til karpedammer for gjødsling av disse. Den hvirvlende strømmen samler forurensninger, såsom forrester og ekskrementer for fisken sentralt i beholderen og de vil falle ned og samles opp i brønnen 13. With the help of the mammoth pump, a continuous circulation of the water in container 1 is achieved. At the same time, the water is oxygenated due to the air bubbling in the mammoth pump, and the water is purified by CO2 in the water being absorbed in the air bubbles that float up and go out into the open. Through the supply lines, the water is renewed over time. The water that is added can be heated to maintain a constant temperature in the water in the container. The contaminated water that flows out of the container through the overflow 10 can either go to carp ponds or to a treatment plant. The line 15 which sucks out solid contaminants from the well 13 can go to the processing of fertilizer or to carp ponds for fertilizing these. The swirling current collects contaminants, such as leftovers and excrement for the fish centrally in the container and they will fall down and be collected in the well 13.
Som man vil forstå vil man kunne få full kontroll med et fiskeoppdrettsanlegg ifølge oppfinnelsen. Det benyttes en tett beholder eller pose, slik at ingen forurensninger tilføres det omkringliggende miljøet. Ekskrementer og forrester som faller ned i brønnen pumpes til et anlegg som ivaretar disse stoffene som gjødning. Overløpsvannet, som er meget lite forurenset, kan føres til et normalt renseanlegg for avløpsvann. Når det dreier seg om perioder der man har medisinert fisken, kan beholderen etter utført medisinering tømmes totalt og fornyes med nytt vann. Det vannet som er forurenset av medisiner kan renses i spesialanlegg. As you will understand, you will be able to have full control with a fish farming facility according to the invention. A tight container or bag is used, so that no pollutants are added to the surrounding environment. Excrement and residues that fall into the well are pumped to a facility that treats these substances as fertiliser. The overflow water, which is very little contaminated, can be sent to a normal wastewater treatment plant. When it concerns periods where the fish have been medicated, the container can be emptied completely after the medication has been carried out and renewed with new water. Water contaminated by medicines can be cleaned in special facilities.
