Interview with SEAWATER Cubes

Easy Engi­nee­ring Magazine

SEAWATER Cubes was foun­ded on 1st August 2018 by Caro­lin Acker­mann (M. Sc. Mar­ke­ting Sci­ence), Chris­ti­an Stein­bach (M. Eng. Engi­nee­ring & Manage­ment) and Kai Wag­ner (M. Sc. Auto­ma­ti­on Tech­no­lo­gy). In order to crea­te a sus­tainable alter­na­ti­ve for the future fish sup­p­ly, the com­pa­ny has deve­lo­ped the SEAWATER Cube, the world’s first com­pact, plug-and-play aquacul­tu­re sys­tem for on land far­ming of sea fish.


Easy Engineering: What are the main areas of activity of the company?

The company’s visi­on is to estab­lish a decen­tra­li­zed and sus­tainable sup­p­ly of fresh fish in Euro­pe, ther­eby secu­ring the population’s nut­ri­ti­on with high-qua­li­ty pro­te­in. We are acti­ve in the food and agri­cul­tu­ral tech­no­lo­gy sec­tor, espe­ci­al­ly in the aquacul­tu­re indus­try. We focus on salt­wa­ter fish far­ming in recir­cu­la­ting aquacul­tu­re sys­tems (RAS).


What’s the news about new products?

The SEAWATER Cube is con­s­truc­ted with a focus on high sus­taina­bi­li­ty. The tech­no­lo­gy is housed in recy­cled ship­ping con­tai­ners on a flo­or space of only around 100 m². This makes the sys­tem per­fect­ly sui­ta­ble for food pro­duc­tion in urban are­as whe­re space is limi­t­ed. 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 in house deve­lo­ped auto­ma­ti­on soft­ware ensu­res the pro­duc­tion of 7.8 t of fish per year with only 1h of work per day.


What are the ranges of products?

In the B2B area, the pri­ma­ry pro­duct is the SEAWATER Cube, which we sell to cus­to­mers as a com­ple­te plant con­cept. In addi­ti­on, we offer indi­vi­du­al com­pon­ents for sale, such as a deni­tri­fi­ca­ti­on sys­tem or a flow pump for recir­cu­la­ti­on sys­tems. We also offer pre-sales sup­port, trai­ning and tech­ni­cal ser­vice for our cus­to­mers. Bes­i­des, we deli­ver our cus­to­mers with all neces­sa­ry raw materials

In the B2C area, we sell our own far­med fish via our online store and pro­vi­de fish mar­ke­ting and sales sup­port to our customers.


At what stage is the market where you are currently active?

The mar­ket whe­re we are acti­ve is curr­ent­ly evol­ving as regio­nal food pro­duc­tion and inde­pen­den­cy from sup­pli­ers beco­mes more and more pro­mi­nent in the food indus­try. The tech­no­lo­gy of ful­ly-auto­ma­ted Recir­cu­la­ting Aquacul­tu­re Sys­tems (RAS) is quite new and we are first mover.


What can you tell us about market trends?

Over­all, the trend in food is moving more and more toward regio­na­li­ty in addi­ti­on to orga­nic qua­li­ty. This is exact­ly whe­re the SEAWATER con­cept comes in, becau­se we want to enable a regio­nal sup­p­ly of fresh fish. Con­su­mers want to know whe­re their food comes from and, in the case of ani­mal pro­ducts, they want to be sure that the ani­mals are kept in a man­ner appro­pria­te to their spe­ci­es and that ani­mal wel­fa­re is respec­ted. That is why SEAWATER places par­ti­cu­lar empha­sis on trans­pa­ren­cy and also allows cus­to­mers to take a look insi­de the fish farm. Other mar­ket trends that we face are inde­pen­dent food sup­p­ly and the con­su­mer trend to redu­ce meat con­sump­ti­on and eat more healt­hy, sus­tainable and high-quality.


What are the most innovative products marketed?

Defi­ni­te­ly the SEAWATER Cube its­elf, becau­se it is the world’s first com­pact, plug-and-play aquacul­tu­re system.


What estimations do you have for 2022?

Fol­lo­wing the suc­cessful finan­cing round, our busi­ness is now picking up speed. We plan our mar­ket ent­ry and sales of the first pilot farms this year. In par­al­lel, we deve­lop the series manu­fac­tu­ring of the cube tog­e­ther with our manu­fac­tu­ring part­ner and are con­ti­nuous­ly working on sys­tem impro­ve­ments and adjus­t­ments to make the Cube even bet­ter. Addi­tio­nal­ly, we are also rese­ar­ching future topics, such as aqua­po­nics. In any case, it remains exci­ting and we are loo­king for­ward to ever­y­thing that is to come!
