Operating Principle: The elevator consists of a helical screw partially or fully enclosed in an inclined tube or trough. When the screw rotates, it continuously moves the contents (water + fish/eggs) upward.
Materials:
Structure: stainless steel or reinforced plastic (corrosion resistant)
Screw: stainless steel or composite materials
Casing: sometimes made of PVC or high-density polyethylene
Typical Dimensions:
Length: from 1 to 10 meters depending on the application
Inclination: between 30° and 45°
Diameter: depends on the flow rate and size of the fish
🐟 Aquaculture Applications
Live fish transfer: from grow-out tanks to sorting stations, trucks, or processing units
Water lifting: for feeding tanks or recirculation systems
Transport of eggs or fry: thanks to the smooth, continuous movement that reduces stress and injury
A fish pump is a device designed to gently transfer live fish from one tank to another, or to grading systems, transport trucks, or processing units, minimizing stress and physical damage. It is essential in intensive or semi-intensive aquaculture operations.
Technical Features
Operation: suction and discharge system, usually via Venturi effect or specially adapted centrifugal pump
Flow rate: varies by model, typically between 50 and 500 m³/h
Fish size: suitable for both fry and market-size fish (e.g. salmon, trout, seabass, seabream)
Discharge height: up to several meters depending on setup
Controls: often equipped with variable speed drives for flow adjustment
Advantages
Gentle handling: reduces injuries, scale loss, and stress
High efficiency: handles large volumes quickly
Easy integration: fits into existing farming systems
Compatible with automatic sorting and weighing systems Available Options
Materials resistant to saltwater (stainless steel, technical plastics)
A fish grader is an essential device in aquaculture farms used to sort fish by size. Grading is crucial to optimize growth, reduce cannibalism, and organize fish batches for sale, vaccination, or transfer.
Technical Features
Operating principle: fish are guided over adjustable ramps or grids, or moved by conveyors through calibrated openings
Grading capacity: up to several tons per hour depending on the model and species
Number of size grades: typically 2 to 6, adjustable mechanically or electronically
Suitable for: fry, juveniles, and market-size fish
The fish sorting table is equipment used to sort fish by size, weight, or physical condition. This device is essential in aquaculture farms to optimize batch processing before transferring fish to tanks, selling, or processing. It also helps to reduce fish stress while ensuring fast and efficient sorting.
Technical Features
Structure: typically made of stainless steel or corrosion-resistant food-grade plastic
Dimensions: adjustable table depending on specific aquaculture needs (customizable length and width)
Sorting system: table inclination, vibrations, or rollers to guide fish into designated compartments or chutes
Capacity: sorting several tons per hour, depending on the model
Feeding: manual or automatic (via conveyor, Archimedes screw, or pneumatic system)
Advantages
Fast and accurate sorting, minimizing handling and stress
Adjustable system for different fish sizes, from fry to adults
Ease of use and maintenance, with integrated cleaning systems
Labor savings and time optimization
Improved fish quality through careful sorting and efficient batch management
Available Options
Electronic control or simple control panel to adjust sorting parameters
Adjustable vibrations or modular ramps depending on fish size and type
Inclined or flat tables depending on aquaculture needs
Integrated washing system for optimal hygiene after each sorting process
Mobile chassis for flexible use at different workstations
