To compare the presence and abundance of mussel larvae and post-larvae in offshore and
inshore areas, plankton sampling was carried out over 18 months in four locations with different
environmental characteristics in the Ria de Vigo (NW Spain). Larvae were more abundant in
3 23 plankton samples (20310 larvae m ) taken near mussel culture rafts than in those from the
3 23 intertidal mussel beds (1.6310 larvae m ). Increments in the abundance of larvae were closely
related with the spawning periods of Mytilus galloprovincialis and with the rise in water
temperature (spring to summer). Post-larvae were found in plankton from the intertidal mussel
beds, from late summer to early autumn, specially in the intertidal zone of exposed rocky shores
3 23 (1.2310 m ). Post-larvae were occasionally found in plankton samples taken near mussel rafts
2 3 (,10 /m ). In the intertidal mussel beds, post-larvae sizes reached 2.1 mm, while the maximum
size found in the vicinity of mussel rafts was of 1 mm. The low number, and even absence, of
post-larvae in plankton samples taken near the surface from localities away from the intertidal
mussel bed could explain why previous studies disregarded the existence of a planktonic
dispersion of post-larvae in this species. However, detailed studies on vertical distribution and
daily (tidal) fluctuation of mussel planktonic stages are needed
