“…A decrease in organic matter was observed between day 19 and 23 (metamorphosis). A similar decrease in the organic content of larvae during metamorphosis had been cited by Videla et al (1998) in Ostrea chilensis, by Rodríguez et al (1990) and Labarta et al (1999a, b) in O. edulis and by Moran and Manahan (2004) in C. gigas. The larvae fed with C.cal presented the highest length, suggesting that larvae fed with these microalgae seem to allocate more energy to the biosynthesis of the shell, which might have affected the success of the metamorphosis (42.81% larvae with foot).…”

“…In contrast, Bartlett (1979) demonstrated that Crassostrea gigas accumulates more energy in the form of proteins than in the form neutral lipids, suggesting that in this species, proteins is the basic energy reserve during metamorphosis. Similar observations were made by Rodríguez et al (1990) for Ostrea edulis.…”

“…Thus, larvae in this stage use stored proteins and/or neutral lipids as shown by the decrease in the energy contribution of these components (Ferreiro et al 1990;Rodríguez et al 1990;Videla et al 1998;Labarta et al 1999a). Some authors have supported the idea that lipids, especially neutral lipids, are the principal energy substrate during larval development and metamorphosis (e.g.…”

“…Holland and Hannant 1974;Ferreiro et al 1990). However, Rodríguez et al (1990) stated that proteins were more important than lipids in metamorphosis and suggested the lack of agreement being due to the differences in experimental conditions. The results of our experiment conciliate both hypotheses.…”

“…The viability of bivalve larvae is limited by the accumulation and/or utilization of either lipids (Millar and Scott 1967;Helm et al 1973;Holland and Spencer 1973) or proteins (Bartlett 1979;Rodríguez et al 1990), but not carbohydrates (Collyer 1957;Holland and Spencer 1973;Bartlett 1979;Labarta et al 1999a), although Haws et al (1993) suggested that carbohydrates may play a part in the optimal utilization of other reserves.…”

Biochemical compounds’ dynamics during larval development of the carpet-shell clam Ruditapes decussatus (Linnaeus, 1758): effects of mono-specific diets and starvation

Successful larval growth and development of bivalves depend on energy derived from internal (endotrophic phase) and external (exotrophic phase) sources. The present paper studies survival, growth and biochemical changes in the early developmental stages (from egg to pediveliger) of the clam Ruditapes decussatus in order to characterize the nutritional requirements and the transition from the endotrophic to the exotrophic phase. Three different feeding regimes were applied: starvation and two mono-specific microalgal diets (Isochrysis aff galbana and Chaetoceros calcitrans). A comparison between fed and unfed larvae highlighted the importance of egg lipid reserves, especially neutral lipids, during a brief endotrophic phase of embryonic development (first 2 days after fertilization). Egg reserves, however, may energetically contribute to the maintenance of larvae beyond the embryonic development. In fed larvae, the endotrophic phase is followed by a mixotrophic phase extending to days 5-8 after fertilization and a subsequent exotrophic phase. Metamorphosis starts around day 20. The intense embryonic activities are supported by energy derived from lipids, mainly from neutral lipids, and the metamorphic activities are supported by energy derived essentially from proteins accumulated during the planktonic phase and depend on the nutritional value of diets. The diet of I. aff galbana proves to be more adequate to R. decussatus larval rearing. The results provide useful information for the successful production of R. decussatus aquaculture.

The sun coral Tubastraea coccinea Lesson, 1829 (Dendrophylliidae) is a widely distributed shallow‐water scleractinian that has extended its range to non‐native habitats in recent decades. With its rapid spread, this coral is now one of the main invasive species in Brazil. Its high invasive capability is related to opportunistic characteristics, including several reproductive strategies that have allowed it to disperse rapidly and widely. To better understand the reproductive biology of T. coccinea and aid in developing management strategies for invaded areas, we investigated aspects of its reproductive performance and life cycle, including the effects of colony size, seawater temperature and salinity, and lunar periodicity on offspring production and larval metamorphosis competence. A total of 18,139 offspring were released in different developmental stages, mainly from the larger colonies, which also produced larvae with longer competence periods. The main reproductive peak occurred during the First Quarter and New Moon phases and was highest in water temperatures around 26°C. Together, these results help to explain the rapid expansion of T. coccinea into non‐native habitats such as the Caribbean and southwestern Atlantic, and will inform actions of the recent Brazilian National Plan for the prevention, eradication, control, and monitoring of sun corals.
