Salinity tolerance and absorption of L-Methionine by some Australian bivalve molluscs

Abstract

The salinity tolerance range of the scallop Pecten fumatus Reeve was 25-40 g 1-1, of the pipi (clam) Plebidonax deltoides (Lamarck) and the flat oyster Ostrea angasi Sowerby, 20-45 g I-1, and of the blue mussel Mytilus edulis planulatus Lamarck and the Sydney cockle Anadara trapezia (Deshayes), 15-45 g I-1. All of these bivalves absorbed substantial amounts of the amino acid L-methionine directly from seawater.
