Feed storage - Aquaculture Engineering

Feed storage

Feed storage depends on the type of feed and how it is packed. If using dry feed, as is most common in intensive aquaculture, the feed can be delivered in bulk and then stored in silos. However, this requires the use of large quantities. Big sacks are used for medium quantities and small sacks for small quantities. Whatever their size, sacks should be stored in buildings, or at least in a sheltered area to protect the contents from animals and birds. The feed sacks must also be protected against direct sunlight to reduce heating and possible destruction of the feed. This is not necessary if insulated buildings are used for storage of dry feed. In the feed storage house concrete floors are typically used because spilled feed is easily cleaned up.

The size of the feed store depends on the feed consumption, types and sizes of feed, and the shelf life. If much feed is bought at the same time, the price for feed and transport is reduced, but this requires a larger feed store. Problems will occur if the feed is stored for too long. The shelf life depends on the composition and the temperature in the feed store, and is given by the feed supplier.

It is important to be aware of the feed handling lines when designing the feed store. If using big sacks, how is the feed going to be transported in and out of the feed store? For instance, if using big sacks, they can be hung up for manual tapping into a wheelbarrow. It is then important to have equipment for lifting the sacks and doors that are wide enough.
