JUKEMA J (1998) Was there a trade in clap net caught Bar-tailed Godwits during the 16th and 17th century?. LIMOSA 71 (3): 124-125.

For centuries Golden Plovers have been caught in clap nets in Frieslaud in the northern part of The Netherlands, but other species were sometimes caught in large numbers as well. From documents from the 18th century there is evidence that Ruff were caught in this manner, as well as large numbers of a species referred to as "Schryen". This was earlier assumed to be Black-tailed Godwit as a result of resemblance of the name to "Skries", which is present-day Frisian for this species. However, Blacktailed Godwits do not often aggregate in large numbers in this area and are hard to catch in clap nets, contrary to Bar-tailed Godwits, locally known as "Reade Skries". Large groups of Bar-tailed Godwits used to be present along the coast of the former "Zuiderzee" before this brackish inland sea was dammed up and turned fresh (present Lake Usselmeer). They were still caught there in clap nets in the first part of the 20th century. Therefor it is argued that there was a significant trade in Bar-tailed Godwits from Frisian clap-nets in previous centuries.
