For Pacific oysters, Crassostrea gigas, data is recorded on date, location, body measurements resp. shell length, live wet weight including shell weight and retention water, shell weight and weight of cocked flesh. The purpose of the data is to index the population dynamics of the non-indigenous species from the beginning of the invasion in the central Wadden Sea.Obtain permission from data set owner(s)Central Wadden Sea, Southern North Sea6.81228.508653.838153.56582003ClassBivalveAchimWehrmannSenckenberg am MeerSuedstrand 40Wilhelmshaven26382Germanyachim.wehrmann@senckenberg.de
Boot-method
Assessment of Pacific oyster abundance (as well shell length and biomass) at 12 stations per site using 1/16 (0.0625) m*m sampling quadrate at oyster covered patches, assessment of oyster coverage at each site by "Step-on-mussel", mean abundance of Pacific oysters is given per m*m/site/year of investigation.
