Graphical summary of the core operation types for duckweed stock maintenance. Laboratory protocols (A) can be represented in Aquarium as sets of defined Types that can be instantiated as real-world laboratory inventory and locations (B). Each OT (e.g. “Transfer duckweed”) in panel A has a corresponding protocol code script (C) written in the Krill programming language using the Integrated Development Environment within the Aquarium web application. When a plan (connected series of operations) is created and launched, the individual operations can be run as Jobs with step-by-step onscreen instructions (D) provided to technicians at the lab bench according to the specifications within the protocol code
