Studies on salinity induced stress on neurosecretory cells, protein, free amino acid content and ammonia excretion rate of penaeid prawn Metapenaeus monoceros (Fabricius).

An important adaptation in organisms to withstand osmotic variations in their external medium, is their efficiency of regulating intracellular concentration. In this context, cell volume regulation appears as a fundamental mechanism. The problem of cell volume regulation becomes crucial in the establishment of organisms in aquatic environment with fluctuating osmolarities
