FOrfarandet kannetecknas av att foder som faller ned under vattenytan registreras av en kameraenhet (2a), att registreringen utOderas och viktas i fOrhallande till lagrad informationoch att utfothingsanordningen (1) styrs och regleras utifran registreringsresultatet. The process can be characterized by the fact that feed that falls below the water surface is registered by a camera unit (2a), that the registration is selected and weighted in relation to stored information and that the ejecting device (1) is controlled and regulated from the outside the registration result.
Anordningen är kannetecknad av en kameraenhet (2a) som registrerar under 10 vattenytan nedfallande foder, en enhet som utvarderar och viktar registreringen i forhallande till lagrad information och en enhet som utifran registreringsresultatet avger styr- och reglersignaler till utfodringsanordningen (1). The device is characterized by a camera unit (2a) which registers feed falling below the water surface, a unit which evaluates and weights the registration in relation to stored information and a unit which, based on the registration result, delivers control and regulation signals to the feeding device (1).
(Se figur 1.) 1 FOreliggande uppfinning avser eft forfarande och en anordning fOr att effektivisera produlction av odlade djurarter, i synnerhet fisk vid fiskodlingar. (See Figure 1.) 1 The present invention relates to a method and an apparatus for streamlining the production of farmed animal species, in particular fish in fish farms.
I fiskodlingar styrs och kontrolleras fiskproduktionen i huvudsak genom reglering av den mangd foder som tilldelas fisken samt genom periodvis iterkommande matningar av MON fiskens storlek och vikt. Dessa matningar sker oftast manuellt och ibland gars bara en visuell uppskatWg byggd pi erfarenhet. In fish farms, fish production is controlled and controlled mainly by regulating the amount of feed allocated to the fish and through periodic feedings of MON the size and weight of the fish. These feeds are usually done manually and sometimes only a visual feed uppskatWg built on experience.
Vanligen sker utfodringen med automatiska utfodringsanordningar som i huvudsak innefattar en foderbehillare till vilken ar ansluten en utmatningsanordning och en spridningsanordning som fOrdelar fodret pi vattenytan. Styrt av en datorenhet sker utfodring vid bestamda tider pi dygnet varvid en viss pi thrhand bestamd mangd foder sprids ut pi vattenytan. Utfodringstider och mangden foder ar givna pi basis av teoretiska berakningsformler lagrade i datorenheten samt samlad kunskap i form av givna parametrar som ar ett resultat av studier och forslcning pi omridet. Fisk i en fiskodling ater normalt huvuddelen av sift foder vid vattenytan. Nar fisken ar matt slutar den ata av fodret varvid det kvarvarande foderoverskottet absorberar vatten, blir tyngre och slutligen sjunker mot bottnen. The feeding usually takes place with automatic feeding devices which essentially comprise a feed hopper to which a discharge device and a spreading device which distributes the feed on the water surface are connected. Controlled by a computer unit, feeding takes place at certain times of the day, whereby a certain amount of feed determined by hand is spread out on the water surface. Feeding times and the amount of feed are given on the basis of theoretical calculation formulas stored in the computer unit as well as accumulated knowledge in the form of given parameters that are a result of studies and research in the field. Fish in a fish farm normally eat most of the sieve feed at the water surface. When the fish is dull, it stops eating the feed, leaving it the remaining feed excess absorbs water, becomes heavier and eventually sinks to the bottom.
For att undvika att fisken fir fOr lite mat ar det latt hant att fiskodlaren som ren sakerhetsitgard Overdoserar foderutmatningen. Foderspillet blir i langden kostsamt och kan dessutom fOrsamra vattnets lcvalitet och darigenom ocksi fiskens levnadsvillkor, vilket i sin tur resulterar i forsamrad tillvaxt. Vid andra tillfallen ater fiskarna upp alit foder men ar fortfarande hungriga. Studier har visat att ett optimalt produktionsutbyte erhills om utfodringen motsvarar exakt den mangd foder som fisken momentant kraver. En onskan har lange varit att styra utfodringen pi ett sidant satt att data optimala produktionsutbyte erhills. To avoid the fish eating too little food, it is easy for the fish farmer to overdose the feed supply as a pure safety yard. Feed waste becomes costly in the long run and can also impair the quality of the water and thereby also the living conditions of the fish, which in turn results in impaired growth. On other occasions, the fish eat up all the feed but are still hungry. Studies have shown that an optimal production yield is obtained if the feeding corresponds exactly to the amount of feed that the fish currently requires. It has long been a desire to control the feeding in a lateral way so that data optimal production yield is obtained.
Olika forsOk har gjorts for att styra utfodringen i fOrhillande till den fodermangd som momentant kravs och ett sidant system ar exempelvis kant frin WO 97/19587. Detta system innefattar en styrenhet i form av en dator som stir i fOrbindelse med en avkanningsenhet for detektering av foderpartiklar passerande genom ett begransat provtagningsomride, varvid pi basis av denna information den momentana tillfOrseln av foder kan regleras. Nar utfodring inte sker befinner sig avkanningsenheten i ett icke aktivt lage. Various attempts have been made to control the feeding in relation to the amount of feed that is currently required and a side system is, for example, edge from WO 97/19587. This system comprises a control unit in the form of a computer which communicates with a sensing unit for detecting feed particles passing through a limited sampling area, wherein on the basis of this information the instantaneous supply of feed can be regulated. When feeding does not take place, the sensing unit is in an inactive state.
Det finns aven en onskan att periodvis kontrollera fisktillvaxten fOr att faststalla cm fisken foljer de satta tillvaxtmilen. Vanligen registreras fisktillvaxten genom att fiskar slumpvis hivas upp ur fiskodlingen och att dessa infingade fiskar mats och vags manuellt. Det ar emellertid Onskvart att i mOjligaste min undvika all manuell hantering di detta innebar ett fOr fisken stOrande stressmoment som inverkar negativt pi fisktillvaxten. Dessutom ar allt 2 manuellt arbete kostsamt och har nackdelen an fiskodlingen inte kan kontrolleras pi avstand via sa kallad fjarrstyrning eller fjarrovervakning Forsok har gjorts fOr att automatisera denna tillvaxtkontroll och tillata att arbetsmomenten styrs pa distans. Fran GB, A 2 087 550 är det kdin en apparat for automatisk berOringsfri matning av volym och vikt hoisk. Anordningen har en speciell matzon genom vilken den fisk vars vikt skall matas passerar. I matzonen är ljuskansliga matorgan anordnade fran vilka erhalls ett matvarde i form av en elektrisk utsignal som kan anvandas for faststillande av fiskens volym och vikt. There is also a desire to periodically check fish growth to establish cm the fish follow the set growth miles. Fish growth is usually recorded by fishing randomly lifted out of the fish farm and that these caught fish are fed and vags manually. However, it is unwise to avoid all manual handling as much as possible, as this meant a stressful moment for the fish that had a negative effect on fish growth. In addition, everything 2 manual work costly and has the disadvantage that fish farming can not be controlled remotely via so-called remote control or remote monitoring Attempts have been made to automate this growth control and allow the work steps to be controlled remotely. From GB, A 2 087 550 it is kdin a device for automatic non-contact feeding of volume and weight hoisk. The device has a special feeding zone through which the fish whose weight is to be fed passes. In the food zone, light-sensing food means are arranged from which a food value is obtained in the form of an electrical output signal which can be used for determining the volume and weight of the fish.
Dessa tva kanda anordningar är var fOr sig relativt komplicerande, kostsamma och utrymmeskravande. Det har sedan ldnge funnits Onskemal om alt ytterligare kunna forenkla och kostnadsminimera stymingen av utfodringen och registreringen av fislctillvdxten och thinned effelctivisera produktionen. Ett huvudandamal med fbreliggande uppfinning dr att astadkomma ett tbrfarande som fOrverkligar dessa Onskemal. Ett annat andamil med uppfinningen är att astadkomma en anordning for genomforande av forfarandet. These two known devices are each relatively complicated, costly and space-consuming. There has long been a desire to be able to further simplify and minimize the cost of feeding and registering fish feed growth and thinned to streamline production. A principal object of the present invention is to provide a method which realizes these desires. Another object of the invention is to provide an apparatus for carrying out the process.
Dessa andamal uppnis genom an forfarandet och anordningen har erhallit de i patentkraven angivna sardragen och kannetecknen. Andra sardrag och fbrdelar med uppfinningen framgar av fbljande beskrivning av ett utforingsexempel med hanvisning till de bifogade ritningarna pa vilka fig. 1 mycket schematiskt askadliggar den princip som ligger till gnmd for foreliggande uppfmning, fig. 2 visar ett utfbrande av uppfinningen for styming av foderutmatningen och registrering av fisktillvaxten med samma anordning. These purposes are ascertained by the method and the device has obtained them in the features and jugs of the patent. Other features and advantages of the invention will become apparent from the following description of an exemplary embodiment with reference to the accompanying drawings, in which Fig. 1 very schematically illustrates the principle underlying the present invention; Fig. 2 shows an embodiment of the invention for controlling feed discharge and registration of fish growth with the same device.
Uppfinningen kommer an framga tydligare av den hdr nedan fbljande beskrivningen tillsammans med bifogade ritningar, som visar ett utforingsexempel av en anordning for genomfbrande av fbrfarandet enligt uppfinningen. The invention will become more apparent from the following description taken in conjunction with the accompanying drawings, which show an exemplary embodiment of a device for carrying out the method according to the invention.
I figurema visas en fiskodlingsanlaggning som innefattar ett fiskodlingsutrymme och en anordning for an effektivisera produktionen av odlade djurarter enligt uppfinningen. The figures show a fish farming facility which comprises a fish farming space and a device for streamlining the production of farmed animal species according to the invention.
Det utrymme i vilket fisken lever och odlas är inte narmare utritat eller beslcrivet. Anvandandet av fbreliggande anordning paverkas eller begransas inte av odlingsutrymmets konstruktion. Det kan vara fragan om bassingkonstruktioner eller annan behallare, nalkassar placerade i hay eller sjO, friodling i sjoar med kontrollerat till- och frinflOde av vattnet eller 30 nfigon annan forekommande begransning av fiskarnas utrymme. The space in which the fish live and are cultivated is not more closely drawn or described. The use of the present device is not affected or limited by the construction of the cultivation space. This can be a question of basin structures or other containers, teddy bear boxes placed in hay or seawater, free-range cultivation in lakes with controlled inflow and outflow of the water or other limited limitation of the fish's space.
Effektiviseringsanordningen enligt uppfinningen innefattar en automatisk foderutmatningsanordning 1. Denna automatiska foderutmatningsanordning beskrivs inte heller narmare di dess konstruktion och funktion redan dr kind och inte dr %remit for uppfinningen. De fiesta utfodringsanordningar innefattar dock en foderbehallare, en 3 frammatningsanordning, en foderspridare och styr- och regleranordningar och dr anslutna till en dator- eller mikroprocessorenhet. The streamlining device according to the invention comprises an automatic feed dispensing device 1. This automatic feed dispensing device is also not described in more detail in its construction and function already in the cheek and not in the remit of the invention. However, most feeding devices include a feed container, a 3 feed device, a feed spreader and control and regulation devices and dr connected to a computer or microprocessor unit.
Effektiviseringsanordningen innefattar vidare en registreringsanordning 2, en dator/milcroprocessorenhet 3 som i sin tur innefattar en bildbehandlingesenhet, en informationshantering/behandlingsenhet, en beralcningsenhgt, en minnesenhet, en styrenhet och en reglerenhet (ingen av dessa enheter är visade i figuren), fOrbindelselankar 4 och slutligen ocksa en tillvaxtregistreringsanordning Registreringsanordningen 2 ska registrera och detektera nedfallande fOremal i odlingsutrymmet och innefattar en kameraenhet 2a. Denna kameraenhet 2a dr placerad vid vattnets yta, eller pa ett forutbestamt djup. Kameraenheten 2a at forslagsvis placerad vid en upphangningsanordning 2b som hiller den i rat lige oavsett vader och vind. Kameraenheten 2a och/eller upphangningsanordningen 2b kan vara foranlcrad vid en flytande anordning som placeras i vattnet eller monterad vid nagon annan anordning. Kameraenheten 2a innefattar med fordel en ccd-kamera som got en digital bildregistrering_ Den information som utlases ur de digitala bilderna kan sedan behandlas, bearbetas, jamfOras och lagras med hjalp av datorer/milcroprocessorer 3 och dari ingiende enheter. The streamlining device further comprises a recording device 2, a computer / milcroprocessor unit 3 which in turn comprises an image processing unit, a information management / processing unit, a beralcningsenhgt, a memory unit, a control unit and a control unit (none of these units are shown in the figure), connection links 4 and finally also a growth recording device The recording device 2 is to detect and detect falling objects in the cultivation space and comprises a camera unit 2a. This camera unit 2a dr located at the surface of the water, or at a predetermined depth. The camera unit 2a should preferably be placed at a suspension device 2b which tilts it in a straight line regardless of the weather and wind. The camera unit 2a and / or the suspension device 2b may be attached to a floating device placed in the water or mounted to any other device. The camera unit 2a advantageously comprises a ccd camera which has a digital image recording_ The information read out from the digital images can then be processed, processed, compared and stored with the help of computers / milcroprocessors 3 and dari input devices.
Registreringsanordningen 2 ska narmare bestamt registrera och deteictera nedfallande foder och denna registrering ska sedan styra och reglera den automatiska foderutmatningen. I vattnet kan det naturligtvis falla ned andra saker an foder. Det kan vara exkrement frail fiskar, fron och bar, levande och dock fiskar och andra djur, med mera. I och med att bildregistreringen är digital kan bildbehandlingen innefatta automatisk kontroll och jamfOrelse av bilden och den information den ger i forhallande till lagrade bilder, lagrad information och lagrade varden och dartill hOrande berakningar. Det kan vara det nedfallande objektets hastighet, storlek, antaVtidsenhet eller fagot annat matbart och jamforbart som resulterar i aft det nedfallande fOremilet bestams vara just foder. Om registreringen beclOms svara mot de uppsatta fOrutsattningarna och kraven gar en styrsignal till den automatiska foderutmatningsanordningen 1 dar foderutmatningen helt eller delvis avbryts. Datorenheten 3 Ian naturligtvis sta i kontakt med andra anordningar eller enheter sa aft det at mOjligt aft kontinuerligt fdrandra forutsattningarna eller aft med hjdlp av insamlad och lagrad information frail till exempel andra odlingsutrymmen eller resultat av forskning bygga upp mer eller mindre sjalvinstruerande system. The recording device 2 shall more specifically detect and detect falling feed and this recording shall then control and regulate the automatic feed output. Of course, other things than feed can fall into the water. It can be excrement frail fish, fron and bar, live and yet fish and other animals, and more. As the image registration is digital, the image processing can include automatic control and comparison of the image and the information it provides in relation to stored images, stored information and stored values and associated calculations. It can be the velocity, size, assumed time unit of the falling object or the bassoon other edible and comparable that results in the falling fOremilet is determined to be just feed. If the registration becomes corresponding to the set conditions and requirements, a control signal goes to the automatic feed discharge device 1 when the feed discharge is completely or partially interrupted. The computer unit 3 may, of course, be in contact with other devices or units so that it is possible to continuously change the conditions or even with the aid of collected and stored information frail for example other cultivation spaces or results of research build more or less self-instructional systems.
Kameraenheten 2a ska som sagt registrera nedfallande foder. FOr aft erhalla en registrerbar kontrast mellan foderpartiklarna och det omgivande vattnet placeras kameraenheten 2a pa sa satt aft linsen riktas nedit fran ytan. Foderpartiklarna reflekterar di 4 det ljus som kommer frin ytan samtidigt som vattnet upplevs som en kompalct och mark bakgrund. Kameraenheten 2a stars inte heller av reflektioner vid vattenytan. Beroende pa valet av kamera kan naturligtvis annan riktning av linsen ge ett tillfarlitligt resultat. Kameraenheten 2a är med fat-del placerad ett stycke under vattenytan far att 5 ytterligve forbattra kontrastverkan, men ocksi far att minska startling av kamerautrustningen frin naturfenomen av olika slag, till exempel regn och blist.open starsta orsaken till att kameran 2a placeras en bit ned är dock att detta kravs for att foderregistreringen ska blir en sker indikering pi att det nedfallande fodret beror pa att fiskama är matta. Fiskar ater vid ytan men simmar naturligtvis runt och rangar upp foder som befinner sig vid ytans narhet ocksi. Nedfallande foder pi ett visst djup kan dock anses vara ett tydligt tecken pi att fiskama har slutat ata. As mentioned, the camera unit 2a must register falling feed. In order to obtain a detectable contrast between the lining particles and the surrounding water, the camera unit 2a is placed so that the lens is directed downwards from the surface. The feed particles reflect you 4 the light that comes from the surface while the water is experienced as a compalct and ground background. The camera unit 2a is also not disturbed by reflections at the water surface. Depending on the choice of camera, of course, different direction of the lens can give a reliable result. The camera unit 2a is barrel-placed slightly below the water surface to further improve the contrast effect, but also to reduce the starting of the camera equipment. free natural phenomena of various kinds, such as rain and blistering. Fishes again at the surface but naturally swims around and ranks up feed that is near the surface ocksi. Falling feed at a certain depth can, however, be considered a clear sign that the fish have stopped eating.
Som alla kameror behaver aven en ccd-kamera ljus far att fimgera. Ljus är tyvarr en bristvara i vatten. Dagsljuset tranger ned en bit under ytan, men om man efterstravar en saker indikering enligt resonemanget ovan si miste omridet runt kameran belysas far att det ska ske en tillforlitlig bildregistrering. En ccd-kameras kanslighet är som storst i ljusspektrat tiara det infrarada. Forskning visar att fiskar stars minst av ljus inom det rada ljusspektrat. Det är darfor lampligt att placera en ljusanordning 2c som avger rOtt ljus vid kameran 2a och fat-se kameran 2a med ett radfilter. Resultatet blir da att man erhaller en tillforlitlig bildregistrering samtidigt som fiskarnas milja inte paverkas namnvart. Like all cameras, a ccd camera also needs light to flicker. Light is unfortunately a scarce commodity in water. Daylight penetrates a bit below the surface, but if you strive for a thing indication according to the reasoning above, say you lose the area around the camera, it is illuminated that it should reliable image registration. The probability of a ccd camera is greatest in the light spectrum tiara the infrared. Research shows that fish starve the least of light within the straight light spectrum. It is therefore convenient to place a light device 2c which emits red light at the camera 2a and mount the camera 2a with a row filter. The result is then that you get a reliable image registration at the same time as the fish's environment is not affected by name.
FOr att pa ett enkek satt fblja upp fiskens tillvaxt och darmed erhilla fler parametrar som kan effelctivisera produktionen är kameraenheten 2a som filth& registreringsanordningen 2 kompletterad med ytterligare en kameraenhet 5a som di utgar en del av tillvaxtregistreringsanordningen 5. Derma andra kameraenhet 5a kan enkelt vara monterad samma upphangningsanordning som den forsta kameraenheten 2a, eller sa kan den vara placerad i arbetslage pa nigot annat lampligt satt. De tva kameroma 2a och 5a placeras i rat vinkel i farhallande till varandra och de samarbetar under den tid som inget utfodring sker. Nar en fisk befinner sig i rat lage vid kameroma 2a och 5a sker en bildregistrering. Kameroma 2a och 5a avlaser det tredimensionella utseendet pi faremilet och om det stammer med lagrad information sparas bilden och den information som den ger. Kameroma 2a och 5a tar digitala bilder samtidigt frin tvi olika hall och genom en digital bildhantering erhills och registreras matvarden pi fiskens langd, hajd och bredd. Utifran dessa varden och med hjalp av berakningsmodeller sker en uppskattning av fiskens volym och med information om olika fiskarters densitet beraknas fiskens vikt. To monitor the growth of the fish in a single way and thereby obtain more parameters which can effelctivate production, the camera unit 2a as filth & recording device 2 is supplemented with another camera unit 5a which forms part of the growth recording device 5. This second camera unit 5a can easily be mounted the same suspension device as the first camera unit 2a, or it can be placed in working class in any other appropriate way. The two cameras 2a and 5a are placed in a steering wheel angle in relation to each other and they cooperate during the time when no feeding takes place. When a fish is in rat position at the cameras 2a and 5a, an image recording takes place. Cameras 2a and 5a read the three-dimensional appearance of the danger mile and if it stems from stored information, the image and the information it provides are saved. Cameras 2a and 5a takes digital photos at the same time from two different halls and through a digital image management is obtained and the food value is registered in the length, height and width of the fish. Based on these values and with the help of calculation models, an estimate is made of the volume of the fish and with information about the density of different fish species, the weight of the fish is calculated.
Berakningarna gars ett antal ginger pa olika fiskar for att utgera ett statistiskt underlag. Berakningarna ger givetvis inte en korrekt viktsuppgift fer den enskilda fisken, men de ger en viktsuppskattning sä att den genomsnittliga fiskens tillvaxt kan kontrolleras. Den information som fas via kameroma kan paverka den fortsatta utfodringen eller resultera i andra styr-, reg,ler- och/elkr informationssignaler, som till exempel information om att fisken har uppnitt den Onskade slutvilcten. The calculations are made a number of gings on different fish to form a statistical basis. Of course, the calculations do not give a correct weight information for the individual fish, but they give a weight estimate so that the growth of the average fish can be controlled. The information transmitted via the cameras can affect the continued feeding or result in other control, reg, ler- and / elkr information signals, such as information about the fish has invented the Desired Final Will.
For att pa avstand mejliggera bade styrning av utfodringen och kontroll av tillvaxten vid fiskodlingar has det hittills eifordrats en kombination av var och en av de bida tidigare namnda kanda anordningama vilket blir bade dyrbart och skrymmande. Med foreliggande anordning reduceras bide kostnaden och utrymmeskravet di anordningen ger det mejligt att med en enkel utrustning klara bade styrning och kontroll. In order to enable remote control of both feeding and control of growth in fish farms, a combination of each of the two previously mentioned known devices has hitherto been required, which becomes both expensive and bulky. With the present device is reduced both the cost and the space requirement in the device makes it possible to manage both control and monitoring with a simple equipment.
Denna styr- och kontrollanordning anvander sig ants& i huvudsak av bara tva kameraenheter 2a och 5a placerade i vattnet. Registreringen av nedfallande foder sker med den ena kameraenheten 2a. RegistreringsomrAdet begransas inte pa nagot satt utan 15 registreringen sker med kameraenheten 2a fritt placerad i vattnet med linsen rilctad neat. This control device uses ants & mainly of only two camera units 2a and 5a placed in the water. The registration of falling feed takes place with one camera unit 2a. The recording area is not limited in any way, but the recording takes place with the camera unit 2a freely placed in the water with the lens exposed.
Kameraenheten 2a kompletteras med ytterligare en kameraenhet 5a som ocksa är fritt placerad i vattnet. Tillsammans registrerar de tva kameraenhetema den fisk som slumpmassigt passerar anordningen. Anordningen tvingar inte in fisken i nagot tringt utrymme eller i nagon for fisken frammande del av vattenutrymmet sisom sker i de kanda anordningar som finns for detta andamal. Detta has varit ett problem di denna tvangsplacering kan orsaka stress hos fiskarna. Kameroma paverkar helt enkelt fiskarnas milje sA lite som det bara as mejligt och fiskama kan ata, vaxa och simma helt ostorda vilket, tillsamrnans med god styrning av utfodringen, medfOr god tillvaxt. The camera unit 2a is supplemented with another camera unit 5a which is also freely placed in the water. Together, the two camera units register the fish that randomly passes the device. The device does not force the fish into any narrow space or into any part of the water space which is foreign to the fish, as occurs in the jugs. devices available for this purpose. This has been a problem in which this forced placement can cause stress in the fish. The cameras simply affect the fish's environment as little as possible and the fish can eat, wax and swim completely undisturbed, which, together with good control of the feeding, leads to good growth.
Naturligtvis kan styr- och kontrollanordningen innefatta ytterligare enheter med specifika uppgifter och hela anordningen, eller dess olika delar, kan vara kopplad till informationspaneler, dataskarmar eller liknande. Informationen kan skickas vidare till mottagningscentraler placerade pa annat hall. Inforrnationen kan aven anvandas for styrning och reglering av andra onskvarda fimktioner vid en fiskodling. Nar fisken till exempel har ran en viss storlek/vikt kan en automatisk slussning ske till ett nytt odlingsutrymme eller populationen kan omdisponeras pa nagot annat satt. Om man driver automatiseringen riktigt lingt skulle fiskodlingen under perioder kunna vara obemannad och de parametrar som Onskas andras kan kontrolleras via olika uppkopplingssystem. Of course, the control and monitoring device may include additional units with specific data and the whole device, or its various parts, may be connected to information panels, computer screens or the like. The information can be forwarded to reception centers located in another hall. The information can also be used to control and regulate other undesirable functions in a fish farm. When the fish, for example, has a certain size / weight, an automatic sluice can be made to a new cultivation space or the population can be reallocated in some other way. If you run the automation really far, the fish farming could for periods be unmanned and the parameters that Onska's others can be controlled via various connection systems.
