  Fish nets

  A net for aquaculture is a specialized tool used in the aquaculture industry to capture, move, or sort fish and other aquatic species safely and efficiently. This type of net is designed to meet the specific needs of aquatic environments where fish need to be handled carefully to avoid injury and stress.

  Here is a typical description of an aquaculture net:

  • Net material: Aquaculture nets are often made from water-resistant materials such as nylon, polyester, or rubber mesh, which minimize the risk of injury to the fish. The mesh is designed to be fine enough to catch the fish without harming them, while being strong enough to withstand heavy use.

  • Handle: The handles of aquaculture nets are often long and extendable to allow access to fish in deep tanks or larger enclosures. They are typically made of metal, aluminum, or lightweight composite materials to offer both durability and ease of use.

  • Net shape and size: Nets used in aquaculture come in various shapes and sizes depending on the type of fish being captured. Some are designed for small fish, while others are built for larger species and require a larger, deeper net.

  • Frame design: The frame of the net is usually reinforced to ensure its stability and durability. It can be round, oval, or square depending on the intended use. The frames are also designed to be easily handled, even under challenging or underwater conditions.

  • Usage: In aquaculture, nets are used for sorting fish, transferring them from one tank to another, or feeding them without causing damage. They are also essential for checking the health of the fish and collecting samples or performing inspections.

  • Benefits: Aquaculture nets help reduce stress and injury to fish, thanks to their specific design that takes into account the fish's fragility. They are also practical for maintaining a clean environment by allowing easy removal of debris or sick fish.

  Aquaculture nets are indispensable tools for industry professionals, ensuring the safe and efficient transport of fish while preserving their well-being.

  Harvesting net

  A fishing net for aquaculture is a specialized piece of equipment used to capture, sort, and harvest fish in aquaculture ponds. Designed to meet the needs of aquaculture partners, this type of net is essential for ensuring an efficient harvest while preserving the health and well-being of the fish.

  • Material: Aquaculture nets are made from water-resistant and durable materials such as nylon, polyester, or PE (polyethylene). These materials are chosen for their strength and longevity to withstand harsh and prolonged working conditions in the water.

  • Mesh size: The mesh size is adapted to the size of the fish being captured. The mesh is typically designed to allow selective capture of fish, while permitting the passage of smaller species or juvenile fish that are not desired.

  • Shape and design: Fishing nets can be circular, rectangular, with or without pockets, or cone-shaped, depending on the fishing methods used. They are often equipped with long, reinforced handles and sometimes with pulley or winch systems to facilitate handling.

  • Usage: These nets are used for harvesting fish at the end of a production cycle or for capturing fish intended for sale. They can also be used for sorting fish by size, moving them from one pond to another, or taking samples for health inspections.

  • Benefits: A fishing net helps efficiently capture fish while reducing the risk of injury or stress. The soft materials and appropriate design help maintain the health of the fish during handling.

  • Durability: These nets are designed to withstand intensive use, including exposure to weather, debris, and water salinity. Their longevity ensures optimal harvests for several years.

  Fishing nets are essential tools for aquaculturists, enabling them to manage harvests efficiently while preserving the quality of the fish and the integrity of the aquatic ecosystem.

  Cages and hapas

  Cages and Pantènes / Hapas for Aquaculture are structures used to raise fish or other aquatic organisms in controlled environments. These systems allow fish to be kept in a defined space while providing an environment that supports their growth and well-being. Cages and Hapas are used in open aquaculture systems, such as ponds, lakes, or marine enclosures, and are essential for optimizing production while preserving ecosystem integrity.

  Description of Cages and Pantènes / Hapas for Aquaculture:

  • Cages for Aquaculture: Cages are closed structures, typically made of mesh, which can be placed in bodies of water such as ponds, rivers, or in the sea. They are designed to contain and raise fish while allowing good water exchange to ensure oxygenation and feeding. Cages are made from durable materials like reinforced plastic, metal, or polyester, which withstand outdoor conditions and the challenges of salty or freshwater environments.

  • Pantènes (Hapas): A Hapa is a type of small floating cage often used for breeding or raising fish in a protected environment. A Hapa is generally smaller than a traditional cage and is used for raising juvenile fish or protecting breeding fish. They can be installed in ponds or recirculating systems, offering more precise management of feeding and the fish's environment.

  • Materials: Cages and Hapas are often made from corrosion-resistant materials such as PVC, polyethylene, or galvanized metal wires to ensure longevity and resistance to the harsh conditions of aquatic environments.

  • Design and Size: The size of the cages varies depending on the number of fish to be raised and the water depth. Cages can be round, square, or rectangular, depending on the design and installation space. Hapas, being smaller, are often rectangular or cylindrical.

  • Ventilation and Oxygenation: Cages and Hapas are designed to allow optimal water exchange, promoting oxygenation and natural circulation. This helps ensure fish health and rapid growth. Some cages are equipped with additional oxygenation systems for environments with low water circulation.

  • Advantages:

    • Environmental Control: Cages and Hapas allow precise control of environmental conditions, leading to more consistent and higher-quality production.

    • Reduced Stress: Fish are protected from external stressors (predators, poor weather conditions) while having enough space to move and feed.

    • Increased Efficiency: By better controlling variables like population density and feeding, these systems contribute to more efficient and sustainable fish production.

  • Usage: Cages are used to raise large quantities of fish like salmon, tilapia, or bass in open or semi-closed aquaculture systems. Hapas, being smaller, are often used to raise fry or to organize breeding activities. Both types of equipment are essential for improving yields and minimizing environmental impact.

  Cages and Hapas for Aquaculture are indispensable tools in modern aquaculture, ensuring sustainable production, optimal fish management, and minimizing risks related to natural conditions.

  Bird repelling devices

  A deterrent device in aquaculture is a system used to keep predators away from fish farming installations, particularly from net pens or cages used to raise fish like salmon or trout.

  🔹 General Description:

  Name: Deterrent (or scaring device)
  Use: Protection of aquaculture farms from predators
  Fields of application: Marine and freshwater aquaculture

  ---

  🔹 Types of deterrent systems in aquaculture:

  1. Acoustic deterrents

     • Emit unpleasant sounds or predator calls.

     • Examples: gas cannons, recorded bird cries, ultrasonic devices.

     • Purpose: create a hostile sound environment for intruders.

  2. Visual deterrents

     • Mimic predators or use shiny/moving objects.

     • Examples: bird-shaped kites, balloons with eye patterns, reflective tapes.

     • Purpose: visually disturb or scare predators.

  3. Physical / mechanical deterrents

     • Barriers, nets, or moving parts (e.g., spinning arms).

     • Sometimes integrated with motion sensors.

     • Purpose: physically block or surprise predators.

  4. Electronic / automated deterrents

     • Systems with sensors and automatic activation.

     • Examples: water jets, low-intensity lasers, smart deterrent systems.

     • Allow for targeted and responsive deterrence.
