STANDARDIZED URBAN FISH FARMING
The SEAWATER Cube is the worlÂd’s first comÂpact, plug-and-play aquaculÂtuÂre sysÂtem. The techÂnoÂloÂgy is housed in four shipÂping conÂtaiÂners on a floÂor space of only around 250 m² (incluÂding manoÂeuÂvring area). This makes the sysÂtem perÂfectÂly suiÂtaÂble for food proÂducÂtion in urban areÂas wheÂre space is limiÂtÂed. We pre-assemÂble the Cube in series proÂducÂtion and conÂnect it at the cusÂtoÂmers site in just a few steps to form an opeÂraÂtioÂnal unit. MechaÂniÂcal and bioÂloÂgiÂcal filÂters recyÂcle 99% of the water within the sysÂtem and remoÂve any wasÂte witÂhout leaÂving resiÂdues. This helps conÂserÂving natuÂral resourÂces and the fish groÂwing up under the best conÂdiÂtiÂons. Our Cube enables an annuÂal proÂducÂtion of around 7.8 tons of fish.

Fix investment
Thanks to the stanÂdarÂdizaÂtiÂon, we can offer the sysÂtem at a fixed priÂce. If necesÂsaÂry, theÂre are also cosÂts for proÂcesÂsing and the first opeÂraÂting resources.

Predictable delivery
The proÂducÂtion time of a sysÂtem is currÂentÂly approx. 4–6 months due to the lead times at our supÂpliÂers. In our facÂtoÂry, we can manuÂfacÂtuÂre two sysÂtems in parralel.

Short assembly time
We assemÂble the sysÂtem in four units in our headÂquarÂter and carÂry them to the cusÂtoÂmer for final assemÂbly on site. The sysÂtem is instalÂled and opeÂraÂtioÂnal within a few days.

Low space requirements
With its comÂpact design and a footÂprint of only 250 m², the Cube fits ideÂal in locaÂtiÂons wheÂre space is limiÂtÂed. AddiÂtioÂnalÂly it is perÂfectÂly suiÂted for urban farÂming conÂcepts as well.
ATTRACTIVE FISH SPECIES
Our farm is speÂciaÂliÂzed for groÂwing saltÂwaÂter fish. This is techÂnoÂloÂgiÂcalÂly more comÂplex than the aquaculÂtuÂre of freshwaÂter fish. With our sysÂtem, we are among the pioÂneers in the field of mariÂne, land-based fish farÂming and see a very larÂge marÂket potenÂtiÂal in mariÂne fish. Sea fish is often proÂcesÂsed in the gasÂtroÂnoÂmy and due to the tasty meat and the eleÂgant optics, the difÂfeÂrent types are parÂtiÂcuÂlarÂly popuÂlar with conÂsuÂmers. For each type of fish, the sysÂtem has to be set up indiÂviÂduÂalÂly to the approÂpriaÂte paraÂmeÂters for the aniÂmal (e.g. water temÂpeÂraÂtuÂre, salt conÂtent, stoÂcking denÂsiÂty). It is theÂrÂeÂfoÂre difÂfiÂcult to give geneÂral stateÂments about proÂducÂtion quanÂtiÂties, opeÂraÂting cosÂts, etc. across all fish speÂciÂes. We would be hapÂpy to disÂcuss speÂciÂfic sceÂnaÂriÂos in perÂsoÂnal with you.
Digitized plant operation
The built-in conÂtrol softÂware reduÂces the workload in the proÂducÂtion to approx. 8 hours per week. All fish knowÂledge is stored in the autoÂmaÂtiÂon so that the opeÂraÂtor acts more in a conÂtrolÂling than a reguÂlaÂting manÂner. For examÂpÂle, the Cube knows when it is time to feed the fishes and how much they need. This inforÂmaÂtiÂon will be given to the feed disÂpenÂsers and the opeÂraÂtor itsÂelf only has to fill them up reguÂlarÂly. In addiÂtiÂon, all important water paraÂmeÂters are recorÂded with the help of various senÂsors and are disÂplayÂed on the conÂtrol panel. In case of deviaÂtiÂons, the sysÂtem knows how to counÂterÂact. The courÂse of the values ​​can be viewÂed via graphs. TheÂre is also an app for the mobiÂle phoÂne, so that access to the data and conÂtrol of the sysÂtem are also posÂsiÂble from home or on the go. In addiÂtiÂon, the sysÂtem can be accesÂsed remoÂteÂly, so that we can actively supÂport you with quesÂtiÂons or problems.
We have lisÂted the most important steps in sysÂtem opeÂraÂtiÂon below.

Monitoring
The daiÂly visuÂal conÂtrol of the fish stock and the moniÂtoÂring of the recorÂded values by the opeÂraÂtor are the most important tasks in the plant operation.

Refilling
In addiÂtiÂon, all important conÂsuÂmaÂbles such as feed, salt or cheÂmiÂcal subÂstraÂtes must be refilÂled and oxyÂgen bundÂles have to be replaÂced at reguÂlar intervals.

Cleaning
The daiÂly care and mainÂtenÂanÂce of the sysÂtem is also an important task. This ensuÂres hygieÂne and funcÂtionÂaÂliÂty and the proÂducÂtion is always preÂsenÂtaÂble to guests.

Analyzing
Some subÂsÂtances canÂnot be detecÂted with senÂsors yet, but in high conÂcenÂtraÂtiÂons they quickÂly becoÂme criÂtiÂcal for the aniÂmals. TheÂrÂeÂfoÂre, weekly water anaÂlyÂzes with strip tests have to be made.
CONTINUOUS PRODUCTION
ConÂtiÂnuous proÂducÂtion is achieÂved through our cohort model. The proÂducÂtion tank is diviÂded into basin areÂas of difÂfeÂrent sizes or age groups (the cohorts). The areÂas are sepaÂraÂted by nets. The fishes have their marÂket size at around 350 to 400 grams and reach this after eight to twelÂve months. From this results a stoÂcking plan in which the aniÂmals spend four months in each cohort. In conÂtrast to the „in-and-out proÂcess“, this means that the entiÂre proÂducÂtion voluÂme does not have to be sold at once, but can be fished perÂmaÂnentÂly accorÂding to demand. If the basin of the marÂket-reaÂdy fish is empÂty, the folÂloÂwing age groups are each moved one secÂtion furÂther and the first area is re-stoÂcked with young fish (seedÂlings).
ALL IN ONE: HARDWARE, SOFTWARE & SUPPORT
After the plant has been comÂmisÂsioÂned, the real work begÂins. It is important for us not to leaÂve the cusÂtoÂmer aloÂne, but to do our part to ensuÂre that our opeÂraÂtors are sucÂcessful. In order to ensuÂre smooth opeÂraÂtiÂons, we conÂclude a serÂvice conÂtract when selÂling the sysÂtem. This includes reguÂlar techÂniÂcal mainÂtenÂanÂce of criÂtiÂcal sysÂtem comÂponÂents, the replaÂceÂment of cerÂtain wear parts as well as a 24-hour avaiÂlaÂbiÂliÂty by phoÂne and remoÂte mainÂtenÂanÂce in the case of techÂniÂcal challenges.

BUSINESS ECONOMICS
BasiÂcalÂly, fish farÂming in a cloÂsed sysÂtem, taking aniÂmal welÂfaÂre and the enviÂronÂment into account, is more cost-intenÂsiÂve than aquaculÂtuÂre in the wild natuÂre. The opeÂraÂtiÂon of a recirÂcuÂlaÂtiÂon aquaculÂtuÂre plant makes senÂse if the proÂject pays off. Even with a stanÂdarÂdiÂzed sysÂtem, the return on an aquaculÂtuÂre busiÂness depends on various indiÂviÂduÂal facÂtors. Among other things, the locaÂtiÂon and the exisÂting infraÂstrucÂtuÂre, the legal requiÂreÂments and funÂding opporÂtuÂniÂties in the respecÂtiÂve fedeÂral staÂte as well as the elecÂtriÂciÂty priÂce and wage cosÂts influence the proÂfiÂtaÂbiÂliÂty calculation.
