“…Shin et al 2002 andCooper andBidwell 2006, have evaluated the burial conduct (burial rate) of mollusks as a response to exposure to metals and pesticides present in sediment. Variations in valve opening and closing time are also considered to be responses to metal exposure (Hughes et al 1987;Inda and Cuturrufo 1999), but this response is not specific to toxic compounds since it is also provoked by factors such as temperature and low oxygen tension (Roger et al 1990;Borcherding 2006).…”

We conducted an evaluation of alterations produced in the valve closing speed of juvenile Argopecten ventricosus (Catarina scallop) exposed to the metals cadmium, chromium and lead, because of the connection of this response to the state of health of the mollusk. Bioassays were conducted with 50 juveniles (length 3 +/- 0.5 cm) exposed to 0.02, 0.1, 0.2 mg Cd l(-1); 0.1, 0.5, 1.0 mg Cr l(-1); 0.04, 0.2, 0.4 mg Pb l(-1) and 0.8 and 1.6 mg Cd + Cr + Pb l(-1) for 480 h. The average valve closing speed at the end of the experiment was under 1 s in the control group, from 2 to 3.6 s in the bioassays with cadmium, from 1.4 to 3.4 s with chromium, from 3 to 12 s with lead, and from 12 to 15 s with the metal mixtures. It was found that there are significant differences between the values recorded in assays with metals and the control (P < 0.05). The retardation of valve closing in the organisms exposed to toxic substances is probably caused by damage to the sensory cilia located on the edge of the mantle.

“…Compared to the control groups (exposed to a salinity of 33 PSU, the mean salinity of seawater), we found that all four B. attramentaria populations substantially reduced their movement distance when exposed to low salinity (13 PSU) and did not significantly alter their locomotion in response to moderate increases or decreases in salinity (43 and 23 PSU; Figure 3a). Reduced activity seems to be a general gastropod response to unfavorable environmental conditions (Elfwing & Tedengren, 2002;Hughes et al, 1987;Kitching et al, 1987). Marine invertebrates commonly reduce their activity when experimentally exposed to salt stress (Berger & Kharazova, 1997;De Lange et al, 2006;Felten et al, 2008;Lawrence & Poulter, 2001;Piscart et al, 2007), presumably to conserve energy for ionic-osmotic regulation (discussed in Ho et al, 2019a Based on the LMM, ANOVA, and post hoc tests, we identified significant differences in locomotor responses between our samples of native and introduced populations, but no significant differences in locomotor responses among our samples of native populations, regardless of lineage.…”

“…infected gastropods (Potamopyrgus antipodarum) affected cercarial development (within the intermediate gastropod host) and that successful transmission was more likely to occur from individual cercariae that had developed in healthier/ fed hosts (Krist et al 2004). Gastropods have been shown to withdraw into their shells due to exposure to a toxic contaminant and under those conditions they are unable to feed (Hughes, Chapman & Kitching, 1987). This reduces the nutritional reserves available to the rediae in which the cercariae are maturing.…”

Effects of host habitat quality on the viability of Cryptocotyle lingua (Trematoda: Digenea) cercariae

In an earlier study it was shown that Cryptocotyle lingua cercariae, matured in Littorina littorea from a polluted marine lagoon, displayed slower horizontal swimming rates, and reduced longevity compared to cercariae released by periwinkles from a cleaner environment. This work investigated whether the pollution-induced reduction in swimming rates was due to an inefficient swimming action or the adoption of a less direct swimming path. In addition, cercariae from L. littorea that had been transferred from an 'unpolluted' to a 'polluted' site for 1 month provided information on the speed with which pollutants affect cercariae through their intermediate hosts. Results indicated that, in general, horizontal swimming rates were reduced due to slower swimming rather than disorientation and longer swimming pathways. Effects of host transplantation to a polluted site were clearly evident after 1 month. Evidence suggested that the pollutants accumulated by the cercariae via their first intermediate host affected the neuromusculature associated with swimming performance rather than sensory structures. Bearing in mind the reduced viability of C. lingua cercariae in polluted sites it is assumed that high prevalence of this digenean in gastropods (at such sites) must be due to their continual introduction by infected birds attracted to these habitats from other areas.
