GP2 medium is an artificial seawater for culture or maintenance of marine organisms

Abstract

Abstract A new four‐part artificial seawater called GP2 Medium is described. It provides a balanced solution for routine maintenance of fishes and invertebrates but is also suitable for axenic culture of phytoplankton. Mixing instructions for phytoplankton culture are given. Instructions for mixing large volumes for routine maintenance of animals are the same as those previously published. The formula is described chemically in terms of ionic and salt concentrations.
