Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

This study concerns the environmental requirements of the shrimp, Crangon crangon, and the prawns, Palaemon adspersus and Palaemon elegans, which occur in the Gulf of Gdansk. Specimens were sampled from the 0.5-1.0 m and 5.0-10.0 m depth layers in the southwestern part of the Gulf, near the seaside resort of Sopot, in 2002-2003. The dominant species was C. crangon, the largest concentrations of which were recorded at 5.0-10.0 m. Seasonal changes were observed in the composition of the population of these three species during the year. P. elegans, a relative newcomer to the Polish zone of the Baltic Sea, has occupied a vacant ecological niche (the 0.5-1.0 m depth zone) and in doing so, has avoided competition with the native C. crangon. In the littoral zone (0.5-1.0 m) off Sopot, and also off Hel and Gdynia, P. elegans occurred together with P. adspersus. The diverse requirements of these three species with respect to biotic (e.g., food) and abiotic factors (e.g., substrate, dissolved oxygen) enable them to coexist in the waters of the Gulf of Gdansk.
