“…Most previous studies on the effect of ocean acidification have dealt with adult individuals; little is known about CO 2 impacts on marine organisms during early development. In addition, several toxicity studies rank bivalve life stages in terms of relative sensitivity to sublethal and lethal effects as: embryos > veligers (D-larvae) > metamorphosing larvae > pediveligers > adults (Beiras & His 1994, His et al 1999. Shell synthesis is significantly suppressed when larvae of the oyster Crassostrea gigas are exposed to seawater equilibrated with CO 2 -enriched (2000 ppm) air (pH 7.4; Kurihara et al 2007).…”

We investigated the effects of seawater equilibrated with CO 2 -enriched air (2000 ppm, pH 7.4) on the early development of the mussel Mytilus galloprovincialis. Mussel embryos were incubated for 144 h (6 d) in control and high-CO 2 seawater to compare embryogenesis, larval growth and morphology with ordinary light, polarized light, and scanning electron microscopy. Embryogenesis was unaffected by exposure to high-CO 2 seawater up to the trochophore stage, but development at the trochophore stage was delayed when the shell began to form. All veliger larvae of the high-CO 2 group showed morphological abnormalities such as convex hinge, protrusion of the mantle and malformation of shells. Larval height and length were 26 ± 1.9% and 20 ± 1.1% smaller, respectively, in the high-CO 2 group than in the control at 144 h. These results are consistent with our previous findings of CO 2 effects on early development of the oyster Crassostrea gigas, although the severity of CO 2 damage appears to be less in M. galloprovincialis, possibly due to differing spawning seasons (oyster: summer; mussel: winter). Results from this and the previous study indicate that high CO 2 (2000 ppm) interferes with early development, particularly with larval shell synthesis, of bivalves; however, vulnerability to high CO 2 differs between species. Taken together with recent studies demonstrating negative impacts of high CO 2 on adult mussels and oysters, results imply a future decrease of bivalve populations in the oceans, unless acclimation to the predicted environmental alteration occurs.

“…Associated with this, HIS et al (1999), in studies on tests with molluscs, also emphasize that species with distinct ecological and phylogenetic characteristics may respond similarly to some toxicants. The same has been highlighted by ENVIRONMENT CANADA (2011) for Echinodermata.…”

“…However, there has been little investigation of this selectivity for different chemicals in marine ecotoxicology. It is only by comparing the behavior of these toxicants in relation to essential metals, normally used as reference toxicants, that it will be possible to confirm the hypothesis that testorganisms of the same taxonomic group do not show differences in sensitivity (ENVIRONMENT CANADA, 2011;HIS et al, 1999).…”

Echinodermata in ecotoxicological tests: maintenance and sensitivityThis work investigates the sensitivity of four species of Echinodermata (Lytechinus variegatus, Echinometra lucunter, Arbacia lixula and Encope emarginata), evaluating the effect of five reference toxicants (Cd, Pb, Cr, Cu and SDS) on embryo-larval development, following the official protocols. It also evaluates techniques for the maintenance of L. variegatus in the laboratory, changes in its sensitivity, and the effects of chemical agents that induce the release of gametes, on the survival rates of the organisms. In terms of the maintenance of L. variegatus in the laboratory, the diet with vegetable content appears to be more favorable for maintenance and maturation in cultivation tanks. Chemical inducers such as KCl and the Anesthetic (lidocaine and epinephrine) resulted in high adult mortality rates, discouraging its re-induction. The tests performed with different species of sea urchin and sand dollar, using different reference toxicants, showed no variations in sensitivity to the more toxic chemicals, indicating that different species can be used for evaluation and environmental impact assessment.

“…On the West coast, three mussel taxa were collected, M. californianus and two species referable to the M. edulis complex, M. galloprovincialis and M. trossulus. The taxonomic status of species in the M. edulis complex is uncertain (His et al, 2000). Mytilus californianus was collected at 31 sites mostly located at jetties, points or capes among the 58 total West coast sites excluding Alaska (viz., 27 sites out of 36 in California, two sites among six in…”
