Oxygen consumption by Nephrops norvegicus (L.), (Crustacea: Decapoda) in relationship with its moulting stage

6 pages, 3 figures, 2 tablesThe study of the rate of oxygen consumption by Nephrops norvegicius (L.) at each moulting stage has been carried out in closed respiration chambers, using an oxygen electrode to measure the oxygen concentration. Although the mean respiration rate seems to be low when compared with other decapod crustaceans of similar weight, the general trends of the variation of the oxygen consumption during the moulting cycle are similar to those described for other species of decapods. It should be noted that, during the process of the ecdysis, there is no oxygen consumption. © 198
