- Hatch Recirculation System


KUBE hatch has been developed for the hatching phase in the production of salmonides. The system has both economic and environmental advantages as well as allowing for a season independent and safe production of fry under optimal aquatic conditions.


Lower energy consumption

The energy demand for heating the water in a recirculation facility is greatly reduced compared to flow through systems because of a considerably lower water consumption.  In addition, the velocity of the pumps is regulated according to the requirements by means of frequency converters. Thus KUBE hatch will be a profitable investment.

Control and quality assurance

All system information is submitted to an integrated control system PLC (Programmable Logic Controller) which transfers the information to a touch screen for the daily operation and to a PC in which the data is logged. The operator can monitor the production, control the water flow, the temperature and the water quality. In case of any fault, alarms are trigged and back-up functions are automatically activated.

Stable environment In KUBE®hatch, the water is treated in a comprehensive water treatment system. The “core” of the system is a bio filter in which bacteria convert the dissolved waste products in the water to non-hazardous compounds. The bacteria in the bio filter reduce the possibility of “opportunistic” and unwanted bacteria and fungi being established and thus prevent potential serious damage to eggs and fry. A stable environment is very important for the fish in the earliest stages during which it has a limited immune defence system. A good start is important for the results later in the production cycle.
