Physiological rates in different classes of sizes of Perna perna (Linnaeus, 1758) submmited to experimental loboratory conditions

Abstract: Physiological studies of the mussel Perna perna in Brazil are almost 30 years behind those of other, more exhaustively investigated species, such as Mytilus edulis. Little is known about the variations in physiological rates due to size and the consequences of maintaining P. perna in laboratory conditions. This work investigated the variations in respiration, clearance, excretion and absorption efficiency rates of P. perna, classified by size and acclimatized in a laboratory, monitoring the mussels' respiratio… Show more

“…Initially, the acclimation capacity was evaluated after 15 days, the time required to enter a state of routine metabolism (Resgalla Jr. et al, 2006) and demonstrate physiological compensations to the variations in temperature and salinity, i.e. to present the same routine metabolism, irrespective of the treatment administered.…”

“…Groups of 20 organisms were maintained in four-liter flasks with aeration and constant photoperiod (12 h light-dark cycle). Two liters of the maintenance water were renewed daily and food was inoculated (phytoplankton Chaetocerus gracilis) at a concentration of 500 Cells.mL -1 (Resgalla Jr., 2004 andResgalla Jr. et al, 2006) in order to establish a standard metabolism in the test organisms, eliminating seasonal variations in their metabolism. All the groups of mussels were kept in filtered seawater (0.5 µm) for 24 h prior to the physiological tests, in order to clean the digestive tract and stimulate their metabolic rates.…”

“…These clearance rates may also be related to a biometric variable such as size or weight (RESGALLA JR. et al, 2006). Knowledge of this relation could be important for preventive actions in public health, particularly in respect to the consumption of mussels as seafood.…”
