Contrasting accumulation biokinetics and distribution of 241 Am , Co , Cs , Mn and Zn during the whole development time of the eggs of the common cuttlefish , Sepia officinalis
Cuttlefish eggs were exposed to 241 Am, Co, Cs, Mn and Zn for different periods of time during the 50-d of the embryonic development at 17°C. Exposures were carried out using background dissolved concentrations of the metals, using the corresponding γ-emitting radiotracers
متن کاملFirst experiments on the maternal transfer of metals in the cuttlefish Sepia officinalis.
The aim of this study was to provide a first insight on the incorporation of eight metals in the eggs of the cuttlefish Sepia officinalis via maternal transfer, using radiotracer techniques ((110m)Ag, (241)Am, (109)Cd, (60)Co, (134)Cs, (54)Mn, (75)Se and (65)Zn). The cuttlefish was fed daily with radiolabelled crabs for two weeks; it then started to spawn every three days. Among the eight trace...
متن کاملInterspecific and geographical variations of trace metal concentrations in cephalopods from Tunisian waters.
The concentrations of six metals (Ag, Cd, Cu, Hg, Pb, and Zn) were investigated and compared in three tissues (arms, digestive gland, and mantle) of three cephalopod species from the Tunisian waters: the common octopus (Octopus vulgaris), the common cuttlefish (Sepia officinalis), and the European squid (Loligo vulgaris). Whatever the species or the sites, the digestive gland displayed the high...
متن کاملPreliminary Results on the Daily and Seasonal Rhythms of Cuttlefish Sepia officinalis (Linnaeus, 1758) Locomotor Activity in Captivity
This research was aimed at characterizing the daily rhythms of locomotor activity of cuttlefish Sepia officinalis (Linnaeus, 1758), a promising aquaculture species, in a captive environment. Cuttlefish were distributed within two tanks equipped with infrared photocells, allowing the monitoring of locomotor activity continuously from August to February. Results showed a preference of cuttlefish ...
متن کاملOcean acidification and temperature rise: effects on calcification during early development of the cuttlefish Sepia officinalis
This study investigated the effects of seawater pH (i.e. 8.10, 7.85 and 7.60) and temperature (16 and 19°C) on (i) the abiotic conditions in the fluid surrounding the embryo (viz. the perivitelline fluid), (ii) growth, development and (iii) cuttlebone calcification of embryonic and juvenile stages of the cephalopod Sepia officinalis. Egg swelling increased in response to acidification or warmin...
