MariSource Hatchery Equipment & Supplies

Pure Aquatics supplies the USA made range of MariSource Hatchery equipment and supplies. Repair and replacement parts are also offered, such as screening material, glue, and water stoppers.

MariSource Vertical Incubation Systems are engineered to increase the survival rate of salmon and trout eggs, provide superior use of floor space, and provide excellent water utilization.

The vertical incubation systems can be stacked in four, eight, twelve, or sixteen – trays, which will allow you to conserve valuable floor space. Water supply needs are minimized because the system requires as little as 11-23 liters per minute/per water tray. Maintaining and working the incubation system is efficient and simple resulting in reduced labor costs.

The end result of the features is an increase in survival rates and the most efficient system available for incubating eggs. If isolation needs are required, we offer a variety of isolation products such as panels, tray segregators, and isolation baskets. MariSource offers hatchery supplies as well. We have spawning knives, egg counters, egg pickers, and measuring boards just to name a few.

MariSource vertical incubators are available to use in various combinations to maximize your manpower, floor space and water supply. The design and construction of these vertical incubators offers several advantages:

  • Vertical flow: Fresh water enters the rear of a water tray, at the top tray, upwells through the egg tray and flows over the front wall inside the water tray into a channel which feeds the next lower water tray unit.
  • Accessibility: Each water tray is designed to slide easily forward on level tracks from the front of the cabinet, enabling eggs to be worked on and returned to the tray without removing it from the vertical incubator cabinet. Hatchery personnel may remove individual egg trays entirely to monitor the progress of eggs and fry without disturbing the remaining trays in the stack.
  • Versatility: MariSource Vertical Incubation Systems may be used in single 8-tray application or may be stacked atop each other to form 16-tray configurations without consuming additional floor space. In the stacked application, a second water source may be introduced to the lower units, thus insuring ample oxygen for each incubator. MariSource also manufactures a 4-tray incubation unit for small quantity applications such as educational or laboratory environments for segregated batch incubation of hybrid eggs.
  • Materials: The cabinet itself is constructed of a one-piece welded aluminum frame for lightweight, convenience in stackability, corrosion resistance, and a long useful life. Interior components are molded of plastic which may be easily cleaned, disinfected after or prior to each use, and are resistant to corrosion. Materials will neither rust nor attack eggs chemically. All incubation components will float.
  • Species-specific: MariSource incubation units are delivered fully assembled with screening material specified by the hatchery for the desired species. Proper screen mesh size allows eggshells to pass through while retaining alevin or fry.
