“…AMGB1 also have been reported to induce settlement of P. canaliculus larvae (Ganesan et al, 2010). The inductive cue was found to be associated with biofilm exudates (chemicals alone) and not the cells in the bacterial biofilm (Ganesan et al, 2012). However, characterization of biofilm exudates and the effects of the fractionated exudates on settlement of this mussel species have not been examined until now.…”

“…Previous studies have suggested that settlement cues obtained from mono-species bacterial biofilms can be associated with the biofilm surface (Lau and Qian, 2001), released into the medium (Fitt et al, 1990) or a combination (Bao et al, 2007a). Based on this mono-species biofilm approach, some studies have investigated bacterial cells without exudates and vice versa as potential sources of inductive cues (Ganesan et al, 2010(Ganesan et al, , 2012.…”

“…Several physical, biological and chemical cues have been identified as inducers of larval settlement and/or metamorphosis across molluscan species (Hadfield & Paul ; Alfaro, Young, & Ganesan ). Such cues include substrate morphology (Hadfield & Paul ; Alfaro & Jeffs ), vibration (Rittschof, Forward, Cannon, Welch, McClary, Holm, Clare, Conova, McKelvey, Bryan, & van Dover ), water motion (Alfaro ), sound (Lillis, Eggleston, & Bohnenstiehl ), microbial biofilms (Ganesan, Alfaro, Brooks, & Higgins ; Tung & Alfaro ; Ganesan, Alfaro, Higgins, & Brooks ; Ganesan, Alfaro, Higgins, Duxbury, & Brooks ), the presence/absence of conspecifics and/or prey species (Hadfield & Paul ), and a range of natural or artificial chemicals (Steinberg, De Nys, & Kjelleberg ; Alfaro, Copp, Appleton, Kelly, & Jeffs ; Young, Alfaro, & Robertson ; Alfaro, Young, & Bowden ; Young, Alfaro, Sánchez‐Lazo, & Robertson ). Specifically, chemical cues have been investigated for a range of bivalve species, including oysters (Coon, Bonar, & Weiner ), mussels (Young, Alfaro, Sánchez‐Lazo, et al .…”

AbstractHerein, we present the first laboratory study on the effects of pharmacologically active compounds on larval settlement of the green-lipped mussel, Perna canaliculus.Competent hatchery-reared larvae were exposed to seawater containing excess K + in the form of KCl and K 2 SO 4 and the neurotransmitters γ-aminobutyric acid (GABA) and acetylcholine.Both KCl and K 2 SO 4 were identified as active inducers of larval settlement with maximum inductions occurring after exposures to 10 and 7.5 mM, respectively. Peak settlement response to KCl was higher (>64%) than that achieved with K 2 SO 4 (>41%). GABA did not induce larval settlement and displayed toxic and settlement inhibitive effects at 10 -4 and 10 -3M. Acetylcholine induced larval settlement (>49%) at 10 -4 M with minimal acute toxic effects (LC < 10%). To gain insight into the class of acetylcholine receptors involved, atropine was used to block the muscarinic-type receptors. Atropine treatment alone did not inhibit settlement compared to control assays, indicating that muscarinic-type receptors are not involved in settlement behavior. Furthermore, results showed that atropine did not significantly decrease acetylcholine induced settlement responses, which suggests an active role of the nicotinic-type receptors in the biochemical pathways of mussel settlement.Results of this study provide new insights on the mechanism of settlement behavior in P.canaliculus, which may have direct application to the growing New Zealand aquaculture industry.
