Assessment of nutritional condition in crustaceans: a review of methodologies and guidelines for applying inexpensive and wide-ranging indices to the spiny lobster Panulirus argus (Latreille, 1804) (Decapoda: Achelata: Palinuridae)
Abstract The review explores the current diversity of methods used to determine the nutritional condition of crustaceans and to provide evidence that standardization is needed to make results comparable among the increasing number of studies in this field. The advantages and disadvantages of inexpen...

Abstract The review explores the current diversity of methods used to determine the nutritional condition of crustaceans and to provide evidence that standardization is needed to make results comparable among the increasing number of studies in this field.

Also reviewed are the environmental factors that impact metabolism based on the nutritional condition concept and the nutritional condition itself. Ocean acidification, temperature, salinity, dissolved oxygen, and noise have been the most studied factors impacting nutritional condition in crustaceans, usually under controlled (laboratory) conditions. Methodological aspect could be nevertheless one of the most important factors affecting nutritional condition estimations.
