Feeding systems for fish farms and RAS

by Fish Farm Feeder, Spain

Let's do a little history. The concept of automatic feeding was born and developed in Norway in the early 1980s. The first equipment was developed for sea cage feeding and was very basic. This equipment consisted of a hopper with a capacity of less than 200kg of processing power, a blower to send the feed to the cages and an auger screw to drive the feed from the silo.

Over the years, the evolution of technology and the demand for equipment with greater performance led to new solutions appearing on the market such as revolver type feed distributors and software that allowed for greater control over feeding.
 

These centralised systems consist of a central station where the silos and all the (automatic) dosing, distribution and control elements are located. The distribution of the feed to the different tanks is done by means of a fluid (typically air in the pneumatic systems) that flows through pipes.

Early in this decade, with the evolution of robotics and artificial intelligence, new power feeding systems have been fully designed and optimised for land-based and RAS systems to emerge from.

Silos
Silos, as necessary tools for safe feed storage, vary in number and capacity according to the needs of the aquaculture company using them. They can be manufactured in various types of material (stainless/galvanised steel, fiberglass, polyethylene, etc) and must be certified for food purposes. They can also be standard or custom-made to cater to the clients needs. An angle at the bottom of the silo ensuring that the feed falls easily is recommended.
