“…These growth rates closely correspond with results from previous work, where S. officinalis of similar size gained 3.5% body mass d -1 at 17°C (Forsythe et al 2002). Under both CO 2 conditions, there was no significant difference between control and treatment final wet mass gained during the 6 wk growth intervals.…”

“…Slopes of the exponential growth curves were used to determine the daily increase in percent body mass. Gross growth efficiency (percent conversion of ingested shrimp into biomass) was calculated for each group on a weekly basis by dividing the weekly increase in animal wet mass (g) by the mass of the food consumed by that group over the same time interval (Forsythe et al 2002). Cuttlebone dry mass and calcium carbonate (CaCO 3 ) content were determined upon termination of the experiment.…”

Ocean acidification and associated changes in seawater carbonate chemistry negatively influence calcification processes and depress metabolism in many calcifying marine invertebrates. We present data on the cephalopod mollusc Sepia officinalis, an invertebrate that is capable of not only maintaining calcification, but also growth rates and metabolism when exposed to elevated partial pressures of carbon dioxide (pCO 2 ). During a 6 wk period, juvenile S. officinalis maintained calcification under ~4000 and ~6000 ppm CO 2 , and grew at the same rate with the same gross growth efficiency as did control animals. They gained approximately 4% body mass daily and increased the mass of their calcified cuttlebone by over 500%. We conclude that active cephalopods possess a certain level of pre-adaptation to long-term increments in carbon dioxide levels. Our general understanding of the mechanistic processes that limit calcification must improve before we can begin to predict what effects future ocean acidification will have on calcifying marine invertebrates.

“…The cuttlebone is produced rapidly, in accordance with the high, exponential growth rates observed in embryonic and juvenile cephalopods (ca. 3.5% of the bodyweight per day in 1.5 g cuttlefish at 17°C, Forsythe et al 2002, Melzner et al 2005). …”

Ocean acidification and temperature rise: effects on calcification during early development of the cuttlefish Sepia officinalis

Abstract: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 warming, leading to an increase in egg surface while the interactive effects suggested a limited plasticity of the swelling modulation. Embryos experienced elevated pCO 2 conditions in the perivitelline fluid (> 3-fold higher pCO 2 than that of ambient seawater), rendering the medium under-saturated even under ambient conditions. The growth of both embryos and juveniles was unaffected by pH, whereas 45 Ca incorporation in cuttlebone increased significantly with decreasing pH at both temperatures. This phenomenon of hypercalcification is limited to only a number of animals but does not guarantee functional performance and calls for better mechanistic understanding of calcification processes.

“…Uno de los factores clave en la acuicultura es optimizar el crecimiento en un mínimo de espacio (Forsythe et al 2002, Iglesias et al 2002, Domingues et al 2003 evitando una excesiva masificación de individuos, que puede tener efectos negativos sobre el crecimiento y el comportamiento de muchas especies. La densidad de cultivo es pues un factor muy importante en acuicultura (Sumpter 1993).…”

0.05) (33.3±19.2% and 37.0±20.2%, respectively). The final density of spider crabs in all trays, after 60 days of experimentation, was similar to the lower density tested (11 spider crabs m-2, equivalent to 3 spider crabs m-2). This density seems to be appropriate for the culture of juvenile spider crab, in the defined culture conditions (T=20±2ºC, natural photoperiod corresponding to the months between September and March in a latitude of 37º 13'N, and salinity close to 35 ups). Growth rates in weight (g) and carapace length (mm), when feeding on boiled and frozen mussels were of 2.1±0.7% BW d-1, and of 0.6±0.3% BW d-1 respectively]]>
