Breakthrough Ocean-Coastal Fish Farm Technology

is mobile, autonomous, sustainable and economic and considers Climate Changes and natural Habitats of Fish

A. Concept and Technology

  1. There is no suitable, sustainable and economic "Ocean-Coastal Fish Farm Concept and Technology" for the global Fish Farmer who wants to go "Offshore", on the World Market.
  2. Our Ocean-Coastal Aquaculture Innovation has disruptive free floating “Cylindrical Fish Cages” submerging to any desired depth for meeting the "Habitat of Fish". The riskless and low cost cylindrical fish cages linked to a mobile Service and Feeding Station assures autonomy and remote control and meets the "Climate Changes".
  3. Alternatively, the one point anchored and circulating cylindrical fish cages, anchored and circulating in coastal deep waters, gets directly served and fed from a land-based Service and Feeding Station.
  4. The mobile and circulating Ocean Fish Farm avoids water pollution, sea lice, diseases, pests and antibiotic treatments. 
  5. Cage + Station + Equipment + Functional Structures are proved in Oceans and in existing Structures over decades and don´t need any further researches.
  6. The static and prototype proved Innovation is technical ready for immediate construction.
  7. Our Ocean-Coastal Fish Farm Innovation is over 10 times cheaper than the actual "Deep Ocean and Offshore Designs".

B. Fish Welfare and Performances

  1. The Climate warming up decrease Oxygen in waters. Porous Hoses fixed in the cylindrical Cages provide Air/Oxygen and atmospheric Air for bubble Fish automaticly by air chambers.
  2. Three free-floating cages are linked to the sites and rear of the Service and Feeding Station.
  3. Cage sizes of L 60 to 100 m x D 16 to 30 m, have volumes of 12.000 to 70.000 m³. 3 cages on a Service Station have volumes of 36.000 to 210.000 m³ for up to 6.300 tons of Salmon/Fish.

C. Station. Cage, Equipment, Function, Patent

  1. Second Hand Cargo Vessels gets modified to low cost Service and Feeding Stations.
  2. A special shield at the conical cage front make an environment in the Cage like in Fjords.
  3. The static and prototype proved Cage and Service/Feeding Station is equipped with Silos, automatic Feeder, Facilities, computerized Programs for Autonomy and Remote-Control.
  4. Electricity is provided by a 12 KW battery, loaded by wind/solar – no fossil energy.
  5. The cages have no wear-out technics and are handled by Air-pressure from Air-Chambers.
  6. Net cleaning by sun/air and dead fish disposal by special systems due to cylindrical cages.
  7. Patent in 2008. Supplementary Patents followed 2014 and 2022 - see Attachments.

D. Promotion, Support, Costs

  1. The EU-EIC Accelerator agreed to Step 1 and supports 70 % and provides EU Credits.
  2. FAO, EU, UN and Marine Recourses state its suitability for global smaller Fish Farm Companies.
  3. R&D and Static works for 10 m wave resistance and for a Workshop-Plan is finalized.
  4. The costs of 40 - 80 €/m³ cage volume competes other Ocean Design of up to-1.500 €.

E. Factory and Marketing

  1. A Factory established at a convinient location delivers free floating “Turn Key Ocean Farms” to any global location.
  2. Market Anylyses state that hundreds of global Fish Farmers would buy the low cost, riskless, sustainable , fish welfare, economic and profitable Ocean-Coastal Fish Farm, if a Demonstration Project proves its great advantages.
  3. The follower Patent Holder has no competitors world-wide and get a global market of hundreds of Fish Farm Customers.

F. Function of a cylindrical Ocean Fish Cage

G. Ocean Fish Farm with 1 and with 3 Cages

Rear-Beam for rear cage

2 Site beams for site cages

The length of the beams is the submerging depth of cages

Innovative Feeder for submerged cages

The 2 white water boxes for demonstration/tests only

Dead Fish Disposal Unit

Model of Dead Fish Disposal

Annex 1 Operation of Beck Cage - Graphics

Service position and Self-Cleaning of Nets

At calm weather, the cage is lifted half out of water for grading, harvesting and net cleaning. At low stocking density the cage rotates frequently, that sun and air can dry and clean nets and structure.

 

Feeding + Conical front

The innovative Beck Feeder press dry pellets into a water-stream and push the pellets into the sections of Beck Cage within seconds at any depth of the cage - regulated by a computer program.
The conical front with its plate-structure, regulate the strong current for fish-welfare.


Dead Fish Collection and Oxygenation

A innovative patented Unit dispose dead fish into an out-site basket. When turning the cage till the basket is above sea level, dead fish are collected by a boat. Divers are not needed anymore.
Diffuse-porous pipes, fixed on the 4 lowest longitude stringers, enrich the water with air or liquid oxygen if needed. Atmospheric air is provided in “Air-Bells” in each section.


Harvesting and grading of Fish

Harvesting and grading is done by section-radius nets (mesh sizes), fixed at the axial structure in each section and pulled by an endless rope to the periphery of the cage and fixed on a stringer.
The mobile fish farm moves to coastal harvest and processing plants and saves transport costs.
A vacuum pump sucks the fish out of each section as shown on the graphic.
