INCUBRAS RAS Hatchery Systems

Overview

Jointly developed by MAP and AST, the INCUBRAS innovative & patented recirculation aquaculture system serves as a crucial part of our “bio-corridors” approach. Each cohort of collected eggs is disinfected, creating a “firewall” strategy for preventing vertical transmission of disease.

Advantage

INCUBRAS are built for easy and resilient operations. They are collapsible and modular which allows easy relocation and phased growth.

Highlights

The INCUBRAS supports a dozen 6.9-liter McDonnel Jars in a closed recirculating format with a total system volume of 220 gallons.

The unit is supported by a 3 cubic foot patented Bubble Bead® bio clarifier that provides both solids capture and biofiltration.

A low energy 1/8 horsepower Iron Might centrifugal pump circulates up to thirty gallons per minute through a 40 Watt UV disinfecting the system water every 8 minutes.

Excess water flows into a constant head system that maintains a fixed head to all hatching jars irrespective of individual jar settings.

Fry are discharged into 4-gallon removable polyethylene totes for the yolk sac absorption stage. The slotted tote outflows are height adjustable to reduce tote weight for fry removal.

The system is designed for a water reuse rate of about 1 month under heavy loading with a backwash interval of once a week.
