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
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.

3. Cages - Static, Size and Costs
Submerging Cage: Static Hs 5,0m = 10m wave resistance
- L 100m x D 16m – 20.000m³ cage volume, 420.750 € : 20.000m³ = 21,00 €/m³
- L 100m x D 20m – 31.000m³ cage volume, 537.000 € : 31.000m³ = 17,30 €/m³
- L 100m x D 24m – 45.000m³ cage volume, 622.500 € : 45.000m³ = 13,80 €/m³
4. Ocean Fish Farm – different cage sices
4.1 Fish Farm with 20.000m³ Cage x 3 Cages = 60.000m³ = 1.262.250 €
- Service station + functional equipment = 1.350.000€, total investment 2.612.250 €
- Depreciation 10 years, stocking density 20kg/m³ - (1.200 tons)
- Fixed Costs/year - 261.225€ : 60.000m³ = 4,35€/m³ : 20kg + interest = 0,25 €/kg Fish
- Variable Costs - fingerling, feed, management, unforeseen 2,50 €/kg Fish
- Sale - 4.50€/kg fish minus fixed/variable costs = profit 1,75 €/kg
- Revenue 1.200.000 kg/fish x 1,75 €/kg is net profit: 2.100.000 €
Repayment is Investment: Revenue 2.612,250 : 2.100 = 1,24 years
4.2 Fish Farm with 31.000m³ Cage x 3 Cages = 93.000m³ =1.611.000 €
- Service Station + functional equipment = 1.350.000 €, total investment 2.961.000€
- Depreciation 10 years, stocking density 20kg/m³ - (1.860 tons)
- Fixed Costs/year – 296.100€ : 93.000m³ = 3,18€/m³ : 20kg + interest = 0,19 €/kg Fish
- Variable Costs – fingerling, feed, management, unforeseen 2,50 €/kg Fish
- Sale – 4,50€/kg fish minus fixed/variable costs = profit 1.81 €/kg
- Revenue 1.860.000 kg/fish x 1,81 €/kg is net profit: 3.366.600 €
Repayment is Investment: Revenue 2.961.000 : 3.366,00 = 0,88 years
4.3 Fish Farm with 45.000m³ Cage x 3 Cages = 135.000m³ = 1.867.500 €
- Service Station + functional equipment = 1.350.000 € total investment 3.217.500€
- Depreciation 10 years, stocking density 20kg/m³ - (2.700 tons)
- Fixed Costs/year – 321.750€ : 135.000m³ = 2,38€/m³ : 20kg + interest 0,15 €/kg Fish
- Variable Costs/year – fingerling, feed, management, unforeseen 2,50 €/kg Fish
- Sale – 4,50€/kg fish minus fixed/variable costs = profit 1,85 €/kg
- Revenue 2.700.000 kg fish x 1,85 €/kg is net profit: 4.995.000 €
Repayment is Investment: Revenue 3.217.500 : 4.995.000 = 0.65 years
