ECONOMIC EFFICIENCY OF AQUACULTURE FACILITIES

Aquacul­tu­re not only makes sen­se from an eco­lo­gi­cal point of view, but also offers a lucra­ti­ve oppor­tu­ni­ty for sus­tainab­le finan­cial invest­ments: an invest­ment in a recir­cu­la­ting aquacul­tu­re sys­tem can gene­ra­te an attrac­ti­ve return in the food sec­tor. Howe­ver, if you want to install such a sys­tem, you should first think care­ful­ly about the ope­ra­ting expen­ses and pos­si­ble inco­me. Ulti­mate­ly, the direct mar­ke­ting of the fish is essen­ti­al for the pro­fi­ta­bi­li­ty. We recom­mend direct sales for inno­va­ti­ve, land-based fish far­ming sys­tems such as our cube. You can use the form below to down­load a sam­ple Excel file for mode­ling. The file ser­ves as a gui­de. It does not claim to be com­ple­te for your own case. We would be hap­py to enter into a more inten­si­ve exchan­ge regar­ding the indi­vi­du­al items in the pro­fi­ta­bi­li­ty cal­cu­la­ti­on if you are spe­ci­fi­cal­ly inte­res­ted in buy­ing a cube.

FURTHER INFORMATION

Production volume vs. Sales volume

A cube pro­du­ces 7,800 kg of raw fish annu­al­ly. When gut­ting the fish, about 10% loss occurs through the entrails. This results in an annu­al sales amount of 6,630 kg of gut­ted fish per pro­duc­tion plant.

Marketing

The sus­tainab­le pro­duc­tion of fresh sea fish on land is asso­cia­ted with cer­tain cos­ts due to the use of high­ly deve­lo­ped fil­ter tech­no­lo­gy. For fish from recir­cu­la­ting aquacul­tu­re, we recom­mend direct mar­ke­ting to the end con­su­mer, gas­tro­no­my or deli­ca­tes­sen shops and pre­mi­um pro­vi­ders in the food retail sector.

Retail prices

Basi­cal­ly, the sales pri­ces are to be deter­mi­ned indi­vi­du­al­ly by the ope­ra­tor. Fish from the SEAWATER Cube can be sold fresh and is grown sus­tainab­ly and under con­trol­led con­di­ti­ons. It is the­re­fo­re pla­ced in the pre­mi­um seg­ment. Accord­in­gly, you can ori­en­ta­te yourself on the pri­ces for com­pa­ra­ble qua­li­ty (e.g. orga­nic fish). Alter­na­tively, pri­ces for meat from regio­nal sources can be used as a guide.

Spe­ci­fic pri­ces per kg of sea bass can be found in our online shop.

Refinement & Shelf life

The refi­ne­ment of the fish, the exten­si­on of shelf life as well as the fur­ther pro­ces­sing of the car­cass can have a posi­ti­ve effect on pro­fi­ta­bi­li­ty. From fil­le­ting to smo­king or boi­ling, the­re are nume­rous tas­ty ways to expand and enhan­ce your range.

Depreciation

We recom­mend a depre­cia­ti­on of the sys­tem over 10 years. The­re is cur­r­ent­ly no sta­tu­to­ry indi­ca­tor for recir­cu­la­ti­on sys­tems, so sewa­ge tre­at­ment plants can be used as a guide.

Financing

In addi­ti­on to finan­cing with your own equi­ty, you can go to the bank. Once a house bank has been found to finan­ce a pro­ject, the­re is a pos­si­bi­li­ty that it will be refi­nan­ced by the Land­wirt­schaft­li­che Ren­ten­bank (in Ger­ma­ny). Then an inte­rest rate of only 1–1.5% can be expected.

In addi­ti­on, many gua­ran­tee banks have spe­cial pro­grams for agri­cul­tu­ral invest­ments. Depen­ding on the invest­ment amount, a part of the defi­ci­en­cy gua­ran­tee is assu­med by the gua­ran­tee bank.

Grants

Grants for invest­ments in aquacul­tu­re are gene­ral­ly avail­ab­le through the Euro­pean Mari­ti­me and Fishe­ries Fund. The pro­gram will be relaun­ched in 2021 and imple­men­ted at the level of the federal sta­tes (in Ger­ma­ny). In the federal sta­tes, the Minis­try of Agri­cul­tu­re, Envi­ron­ment and Con­su­mer Pro­tec­tion is usual­ly respon­si­ble. Depen­ding on the coun­try, the requi­re­ments for app­li­cants and the pos­si­ble fun­ding rates lie bet­ween 20–50%.

Power consumption

A plant con­su­mes 48,000 kWh of electri­ci­ty per year. When cal­cu­la­ting the ope­ra­ting cos­ts, the electri­ci­ty con­sump­ti­on in pro­ces­sing must also be added. This is indi­vi­du­al­ly depen­dent on the num­ber of slaugh­ter days and the machi­nes and devices used.

Water consumption

The annu­al water con­sump­ti­on can be given as around 275 m³. It is made up of the 500 liters that are refil­led in the sys­tem its­elf every day and the water that is used during slaugh­ter and for cleaning.

Seedlings

To pro­du­ce 7.8 t of fish, 21,000 seed­lings are requi­red annu­al­ly. Depen­ding on the type of fish, the­se can be obtai­ned from us. The cost of a sea bass seed­ling is cur­r­ent­ly 0.60 €.

Feed

The faci­li­ty con­su­mes an average of 25 kg of feed per day. This results in a total annu­al requi­re­ment of around 9.3 t. Dif­fe­rent feeds are used depen­ding on the age group. The average pri­ce per kg is cur­r­ent­ly 1.55 €. The feed can also be obtai­ned from us.

Salt

In order to pro­vi­de the ani­mals with an ide­al habi­tat, a spe­cial mine­ral salt mix­tu­re is used wit­hin our sys­ten. The plant is initi­al­ly sal­ted up once when it starts ope­ra­ti­on. Then around 5.5 t of salt are requi­red annu­al­ly. Salt cur­r­ent­ly cos­ts € 0.40 per kg. We also offer an order ser­vice here.

Plant chemistry

The point of plant che­mi­stry inclu­des several items: In order to keep the bio­lo­gi­cal fil­ters run­ning, the use of spe­cial sub­stra­tes is necessa­ry. In addi­ti­on, che­mi­cal test kits are requi­red that can be used to check the water values on a wee­kly basis. A spe­cial clea­ner is also used to clean the pro­ces­sing quip­ment, which must be effec­ti­ve and food-safe at the same time.

Waste disposal

For the dis­po­sing of the fish was­te that remains after slaugh­te­ring, a spe­cial dis­po­sal com­pa­ny must be com­mis­sio­ned . Most pro­vi­ders pro­cess the lef­tovers into high-qua­li­ty ener­gy sources for bio­gas plants.

Workload

The workload in the plant its­elf is an average of 8 hours per week for the fat­tening of the ani­mals. You need to add to this the working hours for pro­ces­sing and mar­ke­ting. The­se times are indi­vi­du­al­ly depen­dent on the sales con­cept pur­sued (num­ber of slaugh­ter days, mar­ke­ting chan­nels, num­ber of buy­ers, com­po­si­ti­on of buy­ers, etc.). For gui­d­ance, for an direct mar­ke­ting con­cept you can plan around 40 working hours for pro­ces­sing and mar­ke­ting with a high pro­por­ti­on of pri­va­te cus­to­mers. This results in a total of 48 working hours per sys­tem per week.

It is advi­s­able to dis­tri­bu­te the work bet­ween several peop­le (e.g. 1 full-time employee, 1 tem­pora­ry worker), as cer­tain tasks are more effi­ci­ent in pairs.

1 module
with container

For out­door instal­la­ti­on, we offer our sys­tem in insu­la­ted ree­fer ship­ping con­tai­ners. The plant brings its housing with it and can be set up almost anywhere.

2 module 
with supply container

By ope­ra­ting several modu­les, it results a wider ran­ge of fish for the con­su­mer as well syn­er­gies and poten­ti­al savings in sys­tem operation.

For exis­ting buil­dings that are to be given a new use and which per­mit the ope­ra­ti­on of salt water aquacul­tu­re, we also offer our sys­tem self-sup­por­ting without a container.

We also offer a con­tai­ner modu­le for slaugh­te­ring and pro­ces­sing the fish, which meets all legal hygie­ne requirements.

SEAWATER MARKETING

Set­ting up direct mar­ke­ting invol­ves a cer­tain amount of work and takes some time. Depen­ding on the mar­ke­ting invest­ment, it can be expec­ted that it will take about 6–12 mon­ths until demand has built up. But this work pays off defi­ni­te­ly, becau­se in direct con­ta­ct with the con­su­mer you not only find loy­al regu­lar cus­to­mers, fans and advo­ca­tes, but also recei­ve a lot of posi­ti­ve feed­back and sug­ges­ti­ons for impro­ving and fur­ther deve­lo­ping your business.

In respon­se to mul­ti­ple requests, we have now suc­cess­ful­ly built up a brand with SEAWATER Fish in our regi­on and tes­ted various sales con­cepts. Our long-term goal is to expand this across bor­ders. In the future, we will estab­lish a fran­chise sys­tem in order to offer Cube buy­ers mar­ke­ting and sales sup­port. Fur­ther infor­ma­ti­on on this is avail­ab­le on request.
