Fish feeding

Continuous and even feeding is important for the growth of the fish. These are important factors for water quality and feed quotient. The feed conversion of the increasingly high-quality feed is a decisive factor for the growth of the fish and thus for the success of the farm.

Monitor & control

LINN AQUA-CONTROL - the life insurance for your fish! To protect yourself from unpleasant surprises and to increase safety, it makes sense to install a system for monitoring and alarming. Safety is provided by the constant monitoring of the oxygen content by means of electronic probes directly in the pond.

LINN - since 1929!

From the experience of our own trout farm - which has been run by the Linn family since 1929 - come the ideas for our devices, which are then further developed until they are ready for series production.
Many devices enjoy patent or utility model protection.
