“…The initial absence of a decrease in glycogen during long-term anoxia (Fig. 2C) seems to be a general characteristic of bivalves, especially those that contain high levels of glycogen (Hummel et al 1989, Isani et al 1989.…”

Metabolic adaptation to 7-d sustained anoxia, and the activation of anaerobic metabolism by a series of O 2 concentrations during a 12-h period, were examined in the ark shell Scapharca kagoshimensis. Laboratory experiments and biochemical analyses were conducted under summer conditions. The pattern of metabolic adaptation to prolonged anoxia was clearly biphasic, similar to that in many other bivalve species. The first, transition stage lasted 12 h and was characterized by sharp decreases in adenylate energy charge, aspartate consumption, and accumulation of succinate and alanine. The second, stationary stage was characterized by glycogen depletion and propionate accumulation. In a series of dissolved oxygen (DO) conditions, the onset of anaerobic metabolism (as indicated by a decrease in fermentative substrate, aspartate; and increase in the end-products, succinate and alanine) was detected only under hypoxic conditions (< 2 mg O 2 L 1 ) and was accompanied by depressed physiological performance, as measured by clearance rate and ammonium excretion rate. However, under milder hypoxia (1-2 mg O 2 L 1 ), a significant clearance rate was still observed, suggesting that both aerobic and anaerobic metabolisms were contributing toward the ATP yield. Lower DO (< 0.61 mg O 2 L 1 ) resulted in an increased rate of anaerobic metabolism and inactivated aerobic ATP production due to impaired filter feeding.

“…Nevertheless, for some groups of benthic animals, including oysters, glycogen is a preferred form of energy reserve, as it has two major advantages: 1) glycogen catabolism is fast providing instant energy; 2) glycogen catabolism can be performed under hypoxic or anoxic conditions. This is particularly important, when oysters keep their shells closed for longer periods (Hummel et al, 1989;Whyte et al, 1990).…”

Biochemical and elemental composition of the offshore-cultivated oysters Ostrea edulis and Crassostrea gigas

Offshore production of seafood is a promising approach to evade numerous specific problems related to aquaculture activities in coastal areas. The aim of this study was to investigate the biological performance of oysters, typical near-shore organisms and potent aquaculture candidates, in an offshore environment. Juveniles of two oyster species, Ostrea edulis and Crassostrea gigas, were transferred to an offshore cultivation site in the German North Sea and cultivated from April to October 2007. Samples were taken every six to eight weeks to determine biochemical and elemental compositions: total glycogen (TG), total protein, total lipid (TL) as well as lipid classes, fatty acids (FA) and the yields and ratios of carbon, hydrogen and nitrogen. Results show an increase in glycogen from spring to early summer for both species, which is related to high food abundance during spring phytoplankton bloom. During summer, glycogen storage revealed clear differences between O. edulis and C. gigas attributing to the reproductive activity of C. gigas but not O. edulis. TG contents ranged between 6% and 23% dry mass (DM) in O. edulis and between 5% and 16% DM in C. gigas. Total protein contents did not show significant seasonal variations and ranged between 34% and 41% DM in both species. TL contents increased during summer, although the increase was clearly more pronounced in C. gigas, followed by a decrease in both species in autumn. TL levels ranged between 7% and 14% DM in both species. Phospholipids and triacylglycerols were the main lipid classes in both oyster species, followed by sterols. FA compositions resembled those of near-shore-grown oysters. We conclude that offshorecultivated oysters exhibit a natural biological performance, emphasizing their suitability as offshore aquaculture candidates.

“…The use of the metabolic reserve, reduction or depletion of glycogen concentrations and how it is used varies between bivalves and is often associated with nutritional conditions (starvation or food availability), the stage of development, sexual maturity (Hummel et al, 1989;Kang et al, 2000;Albentosa et al, 2007;Dridi et al, 2007;Anacleto et al, 2013) and chronic or acute physical or chemical stresses (Nandurkar and Zambare, 2012). According to Patterson et al (1999), glycogen is the primary energy store in bivalves and is a good physiological parameter of bivalve health status or body condition.…”

“…According to Patterson et al (1999), glycogen is the primary energy store in bivalves and is a good physiological parameter of bivalve health status or body condition. Glycogen has been used in different studies, including monitoring its concentration throughout the life cycle of bivalves in the field, during controlled feeding and starvation under laboratory conditions, during relocation, after transport (air and water transport), and under chemical or physical stress (Thompson et al, 1978;Hummel et al, 1989;Patterson et al, 1999;Chen et al, 2001;Newton et al, 2001, Almeida et al, 2007Patrick et al, 2006;Yusufzai et al, 2010;Anacleto et al, 2013).…”

Physiological response of invasive mussel Limnoperna fortunei (Dunker, 1857) (Bivalvia: Mytilidae) submitted to transport and experimental conditions

Successful animal rearing under laboratory conditions for commercial processes or laboratory experiments is a complex chain that includes several stressors (e.g., sampling and transport) and incurs, as a consequence, the reduction of natural animal conditions, economic losses and inconsistent and unreliable biological results. Since the invasion of the bivalve Limnoperna fortunei (Dunker, 1857) in South America, several studies have been performed to help control and manage this fouling pest in industrial plants that use raw water. Relatively little attention has been given to the laboratory rearing procedure of L. fortunei, its condition when exposed to a stressor or its acclimation into laboratory conditions. Considering this issue, the aims of this study are to (i) investigate L. fortunei physiological responses when submitted to the depuration process and subsequent air transport (without water/dry condition) at two temperatures, based on glycogen concentrations, and (ii) monitor the glycogen concentrations in different groups when maintained for 28 days under laboratory conditions. Based on the obtained results, depuration did not affect either of the groups when they were submitted to approximately eight hours of transport. The variation in glycogen concentration among the specimens that were obtained from the field under depurated and non-depurated conditions was significant only in the first week of laboratory growth for the non-depurated group and in the second week for the depurated group. In addition, the tested temperature did not affect either of the groups that were submitted to transport. The glycogen concentrations were similar to those of the specimens that were obtained from the field in third week, which suggests that the specimens acclimated to laboratory conditions during this period of time. Thus, the results indicate that the air transport and acclimation time can be successfully incorporated into experimental studies of L. fortunei. Finally, the tolerance of L. fortunei specimens to the stressor tested herein can help us understand the invasive capacity of this mussel during the establishment process.Keywords: bioinvasion, glycogen, golden mussel, physiology.Resposta fisiológica do mexilhão invasor Limnoperna fortunei (Dunker, 1857) (Bilvalvia: Mytilidae) submetido ao transporte e condições experimentais ResumoA criação bem sucedida de animais em condições de laboratório para processos comerciais ou experimentais é uma cadeia complexa que inclui vários fatores de estresse (ex. coleta e transporte) que tem como consequência a redução das condições naturais do animal, prejuízos econômicos e resultados biológicos inconsistentes.
