Oxygenation for Aquaculture

Fish welfare is a constant concern. Maintaining proper oxygen levels is important to the immune system of fish and leads to stable production and economic benefits for the farmer.

The right oxygen level for optimal fish growth depends on species, size, feeding rate, activity level and water temperature.

Oxygen transfer rate into water is greater with pure oxygen than with air, significantly reducing pumping energy and avoiding the risk of super saturation.

Increased saturation levels offer improved fish welfare and increased growth. In closed or recycled systems, increased saturation levels are essential for fish survival.

The use of pure oxygen is technically and economically superior to simple aeration - the advantages more than compensate for the extra cost.

The SOLVOX® Oxygenation Range

The range optimises dissolution of oxygen in water, distribution of oxygenated water to the fish, and allows dose adjustment for smooth and reliable operation. It’s suitable for all types of aquaculture facilities; whether fresh water or salt water plants, land-based or sea cages.
SOLVOX® A
  • Low-pressure flexible oxygen dissolver.
  • Integrated within pipe installations to oxygenate entire water flow entering the tank.
  • Suitable for salt water and brackish water.
SOLVOX® Stream
  • Flow distributor for improved oxygen distribution and optimum hydrodynamic conditions.
  • Used in combination with oxygenation equipment such as SOLVOX® A.
SOLVOX® B
  • Perforated oxygenation hose fixed onto a support or a rack.
  • No auxiliary energy requirement.
SOLVOX® C
  • Oxygenation cone.
  • Mainly used for fresh water.
  • Oxygenation efficiency close to 100%.
SOLVOX® C Auxillaries
  • Additional equipment that can be combined with Solvox® C.
  • Increases oxygen dosing capacity.
  • Allows mixing of high oxygen concentrated pressurised water with a main water flow without degassing and reduced efficiency.
SOLVOX® OxyStream
  • Low-pressure in tank oxygenation system.
  • Oxygenates and sets flow.
  • Suitable for brackish water and fresh-water tanks.
SOLVOX® CD
  • Ceramic diffuser stones.
  • Used for additional oxygenation and emergency oxygen supply.
SOLVOX® F
  • Oxygen dosing cabinet.
  • Ensures oxygen levels are as constant as possible.
