Self-moving feeders

Self-Supporting Feeders for Aquaculture

Self-supporting feeders for aquaculture are devices designed to automatically distribute food to fish or other aquatic organisms in aquaculture facilities (tanks, cages, ponds, etc.). They allow for efficient, regular, and often programmable feeding, while reducing waste and improving animal growth.

Definition and Operation

A self-supporting feeder is an autonomous system capable of storing and distributing pellets or food to fish without constant human intervention. It is self-supporting, meaning it is independent and mobile, often placed on a float, a stand, or mounted on a barge.

Main Components

Storage tank
- Variable capacity (from a few kg to several tons)
- Airtight to protect the feed from moisture and pests
Mechanical or electronic distribution system
- (auger, rotating disk, air blower)
- (timer, presence sensor, remote control, or automated system)

Power Supply

Solar panels
Rechargeable battery
Direct electric power (less common in remote areas)

Support Structure

Frame made of stainless steel, aluminum, or high-resistance plastic
Floats or legs depending on the environment (marine cage, earthen pond)

Advantages

Automated feeding: consistent and accurate rations
Time and labor saving
Reduced feed waste
Improved zootechnical performance (better growth, optimized feed conversion)
Reduced environmental impact (less uneaten food = less pollution)

Types of Self-Supporting Feeders

Gravity feeders: based on the natural fall of feed, often simple and economical
Blower feeders: propel feed over distances in large cages (used in the sea or large ponds)
Auger or rotor feeders: more precise, with controlled flow rate
Connected feeders: equipped with sensors, cameras, or remote control interface via smartphone or computer
