Association with vessel vectors

Actual evidence of being found in samples in a particular vector from any world region.

Anchor and anchor chains. Organisms found on anchors, anchor chain or within attached sediments, including anchor chain lockers.

Ballast water. Ballast water means water with its suspended matter taken on board a ship to control trim, list, draught, stability or stresses of the ship.

Biofouling. Biofouling means the accumulation of aquatic organisms such as micro-organisms, plants, and animals on surfaces and structures immersed in or exposed to the aquatic environment. Biofouling can include microfouling and macrofouling.

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)

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).
