The concentrations of the main plasma inorganic electrolytes Na + , K + , Ca 2+ , Mg 2+ , Cl ‐ and and PO 4 3‐ have been determined for different orders of marine fishes. For Na + and Cl ‐ a typical decrease was found when passing from cyclostomes, holocephalans and elasmobranchs to teleosts. The concentrations of K + , Ca 2+ and Mg 2+ showed a similar trend except that there was a rise in the teleost group, which showed a large range of variation for these three ions. In the case of PO 4 3‐ no significant differences between groups were found.
