- Palaemon elegans, a new component of the Gulf of Gdańsk macrozoobenthos, colonised the southern Baltic coastal zone in the late 20th and early 21st century. Analysis of the stomach contents of P. elegans revealed 16 plant and animal taxa that these prawns had fed on. The principal dietary component was detritus, with a mean frequency of occurrence in stomachs of > 80%. The most frequently occurring plant components in the diet were algae from the genus Cladophora and the family Ectocarpaceae, while the most significant animal components were Harpacticoida, Chironomidae, Ostracoda and Gammarus spp. The results of the study show that the dietary composition of P. elegans differed significantly between stations and months. The foraging area consisted of two distinctive regions – the Inner Puck Bay, and the Outer Puck Bay together with the Dead Vistula River; two of the stations – Gdynia and Sopot – were distinct from all the others. However, no obvious seasonality in the food composition could be demonstrated.
