The SEAWATER Cube is the world’s first com­pact, plug-and-play aquacul­tu­re sys­tem. The tech­no­lo­gy is housed in four ship­ping con­tai­ners on a flo­or space of only around 250 m² (inclu­ding mano­eu­vring area). This makes the sys­tem per­fect­ly sui­ta­ble for food pro­duc­tion in urban are­as whe­re space is limi­t­ed. We pre-assem­ble the Cube in series pro­duc­tion and con­nect it at the cus­to­mers site in just a few steps to form an ope­ra­tio­nal unit. Mecha­ni­cal and bio­lo­gi­cal fil­ters recy­cle 99% of the water within the sys­tem and remo­ve any was­te wit­hout lea­ving  resi­dues. This helps con­ser­ving natu­ral resour­ces and the fish gro­wing up under the best con­di­ti­ons. Our Cube enables an annu­al pro­duc­tion of around 7.8 tons of fish.

Fix investment

Thanks to the stan­dar­diza­ti­on, we can offer the sys­tem at a fixed pri­ce. If neces­sa­ry, the­re are also cos­ts for pro­ces­sing and the first ope­ra­ting resources.

Predictable delivery

The pro­duc­tion time of a sys­tem is curr­ent­ly approx. 4–6 months due to the lead times at our sup­pli­ers. In our fac­to­ry, we can manu­fac­tu­re two sys­tems in parralel.

Short assembly time

We assem­ble the sys­tem in four units in our head­quar­ter and car­ry them to the cus­to­mer for final assem­bly on site. The sys­tem is instal­led and ope­ra­tio­nal within a few days.

Low space requirements

With its com­pact design and a foot­print of only 250 m², the Cube fits ide­al in loca­ti­ons whe­re space is limi­t­ed. Addi­tio­nal­ly it is per­fect­ly sui­ted for urban far­ming con­cepts as well.


Our farm is spe­cia­li­zed for gro­wing salt­wa­ter fish. This is tech­no­lo­gi­cal­ly more com­plex than the aquacul­tu­re of freshwa­ter fish. With our sys­tem, we are among the pio­neers in the field of mari­ne, land-based fish far­ming and see a very lar­ge mar­ket poten­ti­al in mari­ne fish. Sea fish is often pro­ces­sed in the gas­tro­no­my and due to the tasty meat and the ele­gant optics, the dif­fe­rent types are par­ti­cu­lar­ly popu­lar with con­su­mers. For each type of fish, the sys­tem has to be set up indi­vi­du­al­ly to the appro­pria­te para­me­ters for the ani­mal (e.g. water tem­pe­ra­tu­re, salt con­tent, sto­cking den­si­ty). It is the­r­e­fo­re dif­fi­cult to give gene­ral state­ments about pro­duc­tion quan­ti­ties, ope­ra­ting cos­ts, etc. across all fish spe­ci­es. We would be hap­py to dis­cuss spe­ci­fic sce­na­ri­os in per­so­nal with you.


and user-fri­end­ly

Digitized plant operation

The built-in con­trol soft­ware redu­ces the workload in the pro­duc­tion to approx. 8 hours per week. All fish know­ledge is stored in the auto­ma­ti­on so that the ope­ra­tor acts more in a con­trol­ling than a regu­la­ting man­ner. For exam­p­le, the Cube knows when it is time to feed the fishes and how much they need. This infor­ma­ti­on will be given to the feed dis­pen­sers and the ope­ra­tor its­elf only has to fill them up regu­lar­ly. In addi­ti­on, all important water para­me­ters are recor­ded with the help of various sen­sors and are dis­play­ed on the con­trol panel. In case of devia­ti­ons, the sys­tem knows how to coun­ter­act. The cour­se of the values ​​can be view­ed via graphs. The­re is also an app for the mobi­le pho­ne, so that access to the data and con­trol of the sys­tem are also pos­si­ble from home or on the go. In addi­ti­on, the sys­tem can be acces­sed remo­te­ly, so that we can actively sup­port you with ques­ti­ons or problems.

We have lis­ted the most important steps in sys­tem ope­ra­ti­on below.

The dai­ly visu­al con­trol of the fish stock and the moni­to­ring of the recor­ded values by the ope­ra­tor are the most important tasks in the plant operation.


In addi­ti­on, all important con­su­ma­bles such as feed, salt or che­mi­cal sub­stra­tes must be refil­led and oxy­gen bund­les have to be repla­ced at regu­lar intervals.


The dai­ly care and main­ten­an­ce of the sys­tem is also an important task. This ensu­res hygie­ne and func­tion­a­li­ty and the pro­duc­tion is always pre­sen­ta­ble to guests.


Some sub­s­tances can­not be detec­ted with sen­sors yet, but in high con­cen­tra­ti­ons they quick­ly beco­me cri­ti­cal for the ani­mals. The­r­e­fo­re, weekly water ana­ly­zes with strip tests have to be made.


Con­ti­nuous pro­duc­tion is achie­ved through our cohort model. The pro­duc­tion tank is divi­ded into basin are­as of dif­fe­rent sizes or age groups (the cohorts). The are­as are sepa­ra­ted by nets. The fishes have their mar­ket size at around 350 to 400 grams and reach this after eight to twel­ve months. From this results a sto­cking plan in which the ani­mals spend four months in each cohort. In con­trast to the „in-and-out pro­cess“, this means that the enti­re pro­duc­tion volu­me does not have to be sold at once, but can be fished per­ma­nent­ly accor­ding to demand. If the basin of the mar­ket-rea­dy fish is emp­ty, the fol­lo­wing age groups are each moved one sec­tion fur­ther and the first area is re-sto­cked with young fish (seed­lings).




After the plant has been com­mis­sio­ned, the real work beg­ins. It is important for us not to lea­ve the cus­to­mer alo­ne, but to do our part to ensu­re that our ope­ra­tors are suc­cessful. In order to ensu­re smooth ope­ra­ti­ons, we con­clude a ser­vice con­tract when sel­ling the sys­tem. This includes regu­lar tech­ni­cal main­ten­an­ce of cri­ti­cal sys­tem com­pon­ents, the repla­ce­ment of cer­tain wear parts as well as a 24-hour avai­la­bi­li­ty by pho­ne and remo­te main­ten­an­ce in the case of tech­ni­cal challenges.

by direct mar­ke­ting and refinement


Basi­cal­ly, fish far­ming in a clo­sed sys­tem, taking ani­mal wel­fa­re and the envi­ron­ment into account, is more cost-inten­si­ve than aquacul­tu­re in the wild natu­re. The ope­ra­ti­on of a recir­cu­la­ti­on aquacul­tu­re plant makes sen­se if the pro­ject pays off. Even with a stan­dar­di­zed sys­tem, the return on an aquacul­tu­re busi­ness depends on various indi­vi­du­al fac­tors. Among other things, the loca­ti­on and the exis­ting infra­struc­tu­re, the legal requi­re­ments and fun­ding oppor­tu­ni­ties in the respec­ti­ve fede­ral sta­te as well as the elec­tri­ci­ty pri­ce and wage cos­ts influence the pro­fi­ta­bi­li­ty calculation.
