Product Overview
- 50 % Lower energy consumption
- 60 % Less cleaning
- 85 % Less area
Area Efficient
Area efficient Traditional systems have limited capacity, take up a lot of space and are often heavy to handle. By using CompHatch, the space saved is formidable.
Energy Efficient
Energy efficient CompHatch has much lower water consumption than hatching chutes and combined vessels allowing for a reduced energy consumption. The water replacement is higher and the water is distributed evenly thus securing the supply of oxygen to all parts of the substrate. In addition, the accumulation of waste products is prevented.
Optimal conditions for roe and fry The system is designed so that roe and hatched fry will have optimal conditions regarding to current conditions and water quality. The system is fitted with a separate water supply with a rotameter for adjustment of the desired oxygen rich water quantity to each section. The system is supplied as standard with EasyHatch hatching substrate for good support and prevention of yolk sack abstriction.
Work Lift
In order to improve the ergonometrics and simplify the handling, AM have developed a work lift adapted to CompHatch. The hatching units may be placed on a base, 30 or 50 cm above the floor level to make it easier to serve the lowest shelves from the floor, at the same time for easy access to the upper shelves by using the lift.

Documentation
Havbruksinstituttet AS has documented the effect of CompHatch hatching cabinets and EasyHatch hatching substrate at two of Marine Harvest’s facilities. These were tested against a traditional hatching substrate in a 1 m vessel and a EasyHatch in a 1 m vessel. The results show that the combination CompHatch with EasyHatch has:
- 21 % lower mortality than a 1 m vessel with a traditional hatching substrate.
- 6 % lower mortality than a 1 m vessel with EasyHatch.
- At least 33 % greater capacitythan a 1 m vessel with a traditional hatching substrate without affecting survival and growth.
The operations managers in the two facilities have reported that the work hours related to cleaning were reduced by 4-5 times by use of EasyHatch as opposed to the traditional hatching substrate.
CompHatch with EasyHatch – Optimal combination
From a recent survey in Norwegian hatcheries, combinations of various types of hatching systems and substrates were compared with reference to work hours for cleaning and disinfection before the introduction of new roe. The results show that CompHatch with EasyHatch in average had 56 % less work hours than other combinations in the survey.
