Growth patterns of Mytilopsis leucophaeata, an invasive biofouling bivalve in Europe. Biofouling 22(3-4): 221-231 Comments: There are several life stages known for Mytilopsis leucophaeata. After external fertilization of gametes a short-living trochophora stage identified. It transforms into veliger stage. Just before becoming benthic, veliger undergoes pedveliger stage swimming close to the bottom. After primary settlement the organism in on postveliger stage. Young individuals, morphologically similar to adults, but immature, are referred to as juveniles.(Verween, 2006;Verween, 2006-2007) |

(2010). The Zebra mussel in Europe. pp. 29-43 http://www.issg.org/database/ecology, 01/12/2011 Comments: Mytilopsis leucophaeata is a dioecious species that reproduces sexually by external fertilization (Zebra Mussel Information System, 2002). Reproduction may occur continuously in some locations or from the late spring to early fall in others (Verween et al, 2009; Kennedy, 2010). The minimum reported temperature required for spawning is about 13-15°C (Verween et al, 2010). |

DOI: 10.1007/s10452-010-9344-6 Comments: Within 24 hours after the external fertilisation of gametes, released in the water column, a short-living trochophora stage is identified. |

Journal of Molluscan Studies 77(2): 154-164 Comments: Mytilopsis leucophaeata is a filter-feeder primarily on planktonic algae and zooplankton, other possible food sources are bacteria, detritus, and organic matter. They are able to ingest particles as small as 4µm, nad can feed on flagellate Isochrysis oalbana in laboratory cultures (Mackie and Schloesser, 1996; Verween, unpubl data). The larvae stage of Mytilopsis leucophaeata is planktotrophic. In experiment conditions (Kennedy, 2011) it was fed by algal food (Isochrysis sp. clone CISO). |

Mytilopsis leucophaeata is a filter feeder that consumes phytoplankton, plant detritus, diatoms, and other organic matter. |
