The heavy metal concentration (e.g., Mn, Zn, Pb and Ni) were determined in soft tissues and shells of freshwater mussels (Lamellidens marginalis) at the various sites of Dhanmondi lake, Dhaka, Bangladesh between the period April, 2010 and March 2011. The heavy metal concentrations in shells and soft tissues of freshwater mussels were tended to vary significantly among sampling points and seasons in Dhanmondi Lake. Distribution of heavy metals in shell and soft tissue of Lamellidens marginalis followed the order Mn>Zn>Pb>Ni, respectively. According to the t-test, level of manganese, zinc and lead under investigation between shell and tissue showed statistically significant differences [Mn: t=-11.387; df=16; P=0.000; Zn: t=-2.590; df=16; P=0.020 and Pb: t=-2.8679; df=16; P=0.011].

AbstractCo-infections are common in host-parasite interactions, but studies about their impact on the virulence of parasites/diseases are still scarce. The present study compared mortality induced by a fatal bacterial pathogen, Flavobacterium columnare between brown trout infected with glochidia from the endangered freshwater pearl mussel, Margaritifera margaritifera, and uninfected control fish during the parasitic period and after the parasitic period (i.e. glochidia detached) in a laboratory experiment. We hypothesised that glochidial infection would increase host susceptibility to and/or pathogenicity of the bacterial infection. We found that the highly virulent strain of F. columnare caused an intense disease outbreak, with mortality reaching 100% within 29 h. Opposite to the study hypothesis, both fresh ongoing and past infection (14 months post-infection) with glochidia prolonged the fish host’s survival statistically significantly by 1 h compared to the control fish (two-way ANOVA: fresh-infection, F1, 82 = 7.144, p = 0.009 and post-infection, F1, 51 = 4.227, p = 0.044). Furthermore, fish survival time increased with glochidia abundance (MLR: post-infection, t = 2.103, p = 0.045). The mechanism could be connected to an enhanced non-specific immunity or changed gill structure of the fish, as F. columnare enters the fish body mainly via the gills, which is also the glochidia’s attachment site. The results increase current knowledge about the interactions between freshwater mussels and their (commercially important) fish hosts and fish pathogens and also emphasise the importance of (unknown) ecosystem services (e.g., protection against pathogens) potentially associated with imperilled freshwater mussels.
