  Closed-Circuit Aquaculture Systems (RAS)

  Closed-circuit aquaculture systems, also known as Recirculating Aquaculture Systems (RAS), are systems that allow for the partial or total recycling of farming water. Unlike open systems (ponds, tanks, or sea cages), they minimize water consumption and reduce environmental pollution.

  Principle of Closed-Circuit Aquaculture

  An RAS operates through several essential stages:

  1. Raising tanks: Designed to ensure uniform water volume and facilitate the removal of organic waste (feces and uneaten food).
  2. Mechanical filtration: Removes solid particles such as feces and food residues.
  3. Biological filtration: Houses nitrifying bacteria that convert toxic ammonia into less harmful nitrates.
  4. Disinfection: The use of UV lamps or ozone eliminates pathogenic germs present in the water.
  5. Aeration and oxygenation: The addition of air or oxygen removes CO2 produced by fish metabolism and enriches the water with oxygen for respiration.
  6. Temperature control: Heating or cooling equipment maintains the optimal water temperature for fish growth and reproduction.
  7. Regulation of parameters: Controls temperature, pH, salinity, and other factors to ensure optimal fish growth.

  Advantages of the RAS system

  Water savings (reduces consumption by 90-99%)

  Precise control over farming conditions

  Reduction of diseases and parasite

  Lower environmental impact

  Food distribution system

  Aquaculture France offers a wide choice of food distributors. Feeding fish is a daily task that has a strong impact on the performance of an aquaculture farm. Distributed in too small a quantity, the fish grow slower and reach their commercial size later. Distributed in too large a quantity, the food is lost and its decomposition degrades the quality of the water. Aquaculture France offers belt feeders controlled by a mechanical clock. We keep all spare parts in stock to be as responsive as possible in the event of a breakdown. Aquaculture France also distributes programmable automatic feeders. It is possible to adjust the frequency of distribution of the food but also the quantity distributed and the duration of distribution of the ration. These devices can be controlled locally by a control panel. For larger installations, it is possible to centralize the controls on a PC. This solution becomes economical during installation but it is also economical in operation since it simplifies adjustments.
  
  Aquaculture France also distributes professional systems for fish feeding. This type of automatic equipment. The food is expelled by a pneumatic feed. It is possible to mix several foods and distribute them in basins located up to 800 m from the silo. The fish food dispenser panel ends with automatic or pendulum systems for breeding in ponds and outdoor basins. Extensive fish farming operates on sites sometimes far from the electricity network. For these applications, Aquaculture offers feeders equipped with solar panels that operate completely autonomously.

  Cooling and heating...

  Thermal regulation of an aquaculture breeding tank or an aquarium is a very important element.

  The objective of temperature regulation is determined through a multi-level study.

  • First, a thermal assessment of the installation helps to understand the dynamic balance of the tank(s) and measure thermal gains and losses in the circuit under all operating conditions.
  • Based on this analysis, we can define the cooling and heating power needed, either occasionally or continuously, for the system. Several solutions are available: chillers, heat pumps, boilers, electric heaters...
  • Once these power requirements are known, the next step is to determine how to inject this energy into the water circuit. In-line equipment is sized and installed on the network (heat exchangers).
  • Finally, precise regulation is essential. The goal is to find the best solution to accurately control the amount of energy (heating and/or cooling) supplied to the water circuit to maintain the desired setpoint temperature.

  Aquaponics and spirulina

  Aquaponics is a technique that allows for the raising of fish and the cultivation of plants within the same system. The waste produced by the fish is used as nutrients for the plants. The recycling of waste ensures a healthy environment for the fish and promotes plant growth.

  Aquaponics is a cultivation system that combines aquaculture (fish farming) and hydroponics (soil-less plant cultivation) in a symbiotic cycle. This system relies on a natural balance where fish waste serves as nutrients for the plants, while the plants filter and purify the water for the fish.

  How does it work?

  • Fish: They produce waste rich in ammonia.
  • Bacteria: They transform this waste into nitrates, a form that plants can absorb.
  • Plants: They absorb these nutrients, thus purifying the water.
  • Water circulation: Once filtered by the plants, clean water is returned to the aquarium or tank.

  Advantages of aquaponics

  • Eco-friendly: Less water waste than traditional agriculture.
  • Productive: Allows the cultivation of vegetables and fish farming at the same time.
  • No chemical fertilizers: Nutrients come naturally from the fish.
  • Autonomous and sustainable: A well-designed system requires little intervention once established.

  Which plants and fish are suitable?

  • Common fish: Tilapia, trout, carp, goldfish.
  • Ideal plants: Lettuce, basil, tomatoes, strawberries, aromatic herbs.

  It is an innovative cultivation method, ideal for local and sustainable production, whether on a small scale at home or on a larger scale for urban farms.

  Degassing, aeration...

  Degassing Techniques

  Degassing in aquaculture is a process that removes unwanted dissolved gases from the water in fish farming tanks. These gases, such as carbon dioxide (CO₂), nitrogen (N₂), or hydrogen sulfide (H₂S), can be harmful to fish and other aquatic organisms.

  Why is degassing important?

  • -        Removal of CO₂: Excessive accumulation of CO₂ can lower the water’s pH and affect fish respiration.

  •         Reduction of dissolved nitrogen (N₂): Excess nitrogen can cause gas embolism, a problem similar to decompression sickness in divers.

  •         Elimination of hydrogen sulfide (H₂S): This toxic gas can be fatal to fish even at low concentrations.

  •         Degassing techniques in aquaculture

  •         Forced aeration: The use of waterfalls, aeration towers, or air diffusers promotes gas exchange and improves degassing.

  •         Gas stripping: Degassing columns force water through materials that facilitate the release of unwanted gases.

  •         Forced ventilation: The introduction of high-speed air or partial vacuum in water circuits accelerates the removal of dissolved gases.

  • egassing is a crucial step in maintaining good water quality and ensuring the health of fish in aquaculture.

  Aeration Techniques

  Aeration in aquaculture increases the concentration of dissolved oxygen (O₂) in water. Oxygen is essential for the survival and growth of fish and other aquatic organisms. Aeration also improves water quality by helping to remove harmful gases such as carbon dioxide (CO₂) and ammonia (NH₃).

  Why is aeration important?

  • -        Oxygen supply: Fish and beneficial bacteria in the biofilter need oxygen to survive and function properly.

  •         Elimination of toxic gases: Aeration helps to remove CO₂ and other harmful gases like H₂S (hydrogen sulfide).

  •         Improved fish metabolism: Better oxygenation promotes growth and reduces stress in fish.

  •         Reduced risk of eutrophication: Proper oxygen circulation prevents excessive nutrient buildup, limiting the proliferation of harmful algae.

  Aeration techniques in aquaculture

  There are several methods to ensure proper water aeration:

  • -        Natural aeration: Using wind and natural water movement (e.g., waterfalls, streams). This simple technique is suitable for open systems such as ponds.

  •         Mechanical aerators: Devices that increase oxygen exchange between air and water through agitation or air injection. Examples include:

  •         Paddlewheel aerators: Create waves and bubbles to oxygenate water.

  •         Jet aerators: Spray water into the air for better oxygen contact.

  •         Diffused air aerators: Use pressurized air diffusers to release fine oxygen bubbles into the water.

  How to choose the right aeration method?

  The choice depends on several factors:

  • -        Type of aquaculture system (ponds, tanks, RAS)

  •         Fish density (the more fish, the more oxygenation is needed)

  •         Cost and energy availability

  •         Water parameters (temperature, salinity, etc.)

  Proper aeration is essential for maintaining healthy and profitable aquaculture production.

  Oxygenation Techniques

  Oxygenation in aquaculture is the process of maintaining an optimal level of dissolved oxygen (O₂) in the water to ensure fish health and optimize their growth. It is especially crucial in intensive farming systems where oxygen consumption is high.

  Why is oxygenation important?

  • -        Fish respiration and aquatic organisms consume oxygen.

  •         Low oxygen levels cause stress, reduced appetite, and slower growth.

  •         Oxygen deficiency can lead to mass fish mortality and significant growth delays.

  •         Nitrifying bacteria that convert ammonia (NH₃) into nitrites (NO₂⁻) and nitrates (NO₃⁻) need oxygen to function.

  •         Insufficient oxygenation can lead to toxic waste accumulation.

  •         Reduction of diseases and improved metabolism

  • -       Good oxygen levels reduce stress and improve fish resistance to diseases.

  •         Oxygen promotes digestion and nutrient absorption.

  •         Optimal oxygen levels enhance farming performance.

  Oxygenation methods in aquaculture

  • Injection of pure oxygen (direct oxygenation): Using liquid oxygen (LOX) or oxygen generators. This method is highly effective and is used in high-density systems such as recirculating aquaculture systems (RAS). Oxygen supply can be adjusted based on fish consumption.

  • Several systems can enrich water with oxygen, including:

  •         Oxygenation cones

  •         Jet platforms

  •         Low- or medium-pressure oxygen systems

  •         Pure oxygen diffusers

  •         Use of plants and algae: In extensive systems, aquatic plants and phytoplankton produce oxygen through photosynthesis. However, at night, plant respiration consumes oxygen, which can cause problems.

  Factors influencing oxygenation

  The level of dissolved oxygen depends on several parameters:

  • -        Temperature: Warm water holds less oxygen than cold water.

  •         Salinity: Salty water naturally contains less oxygen than freshwater.

  •         Fish density: The more fish, the higher the oxygen consumption.

  •         Biological activity: Biofilter bacteria and decomposers also consume oxygen.

  How to optimize oxygenation?

  • Continuously monitor dissolved oxygen levels using oxygen sensors.

  •         Adjust aeration and oxygenation based on fish needs.

  •         Use aerators or pure oxygen to prevent stress and losses.

  •         Avoid overfeeding, which increases oxygen consumption by waste-decomposing bacteria.

  Oxygenation is a key factor in maximizing productivity and ensuring a healthy environment for fish.

  Electric fishing

  Electric Fishing Equipment

  Electric fishing equipment is primarily used for scientific studies of fish populations and sometimes for aquatic resource management operations. This method allows fish to be temporarily captured without injury, so they can be identified, measured, and released.

  Electric Fishing Generator

  This is the main component of the device. It converts the energy from a battery or a generator into a pulsed electric current sent into the water. It is often portable (worn as a backpack) or installed on a boat for larger areas.

  Anode and Cathode

  The anode (often a metal pole with a ring at its end) disperses the electric current into the water.

  The cathode is usually a cable or a metal plate submerged in water, ensuring the electrical circuit is completed.

  Power Source

  Batteries (for portable devices): Usually lithium-ion or lead-acid, they must be powerful enough to ensure efficient operation.

  Gasoline generators (for onboard or fixed systems): Used for operations requiring more power.

  Safety Equipment

  • Insulated suits and gloves to prevent electrocution.
  • Emergency switches to immediately cut off the current in case of an issue.
  • Signage or markers to prevent accidents with other water users.
  • Fish Capture and Handling Equipment
  • Insulated nets to retrieve fish without the risk of an electric shock.
  • Water-filled tanks to hold fish after capture.
  • Measuring instruments (scales, measuring tape) and tagging equipment for scientific studies.

  This equipment is used by trained professionals, as electric fishing is a regulated technique requiring specific authorizations.
