Macrobenthic invertebrates, dwelling in the sediment (=infauna) were sampled in the Škocjanski zatok Nature Reserve near Koper, Slovenia on 26th of August 2014.
The sampling took place in Škocjanski zatok Nature Reserve which is an isolated water reservoir connected through the canal with the Port of Koper.
Figure 1: Sampling of macrobenthic invertebrates dwelling in the sediment (=infauna) in the brackish lagoon of the Škocjanski zatok Nature Reserve on 26th of August 2014.
In the brackish lagoon 8 sampling stations were selected. In each station three samples were collected by the use of a box-corer (20 cm x 20 cm x 10 cm). All the material was transported to the MBS (NIB) laboratory, where samples were sieved through a 1 mm mesh.
Figure 2: The bivalve Arcuatula senhousia was firstly found in Slovenian coastal waters in 2005. Nowadays the species could be found in great density in very shallow areas of the Škocjanski zatok Nature Reserve, close to the city of Koper.
Invertebrates were then collected and separated into higher taxa (Porifera, Mollusca, Polychaeta, Echinodermata, Crustacea and Bryozoa).
Figure 3: The sedentary polychaete Ficopomatomus enigmaticus was firstly recorded in the Sečovlje Salina in 1994. Nowadays it is an established species in Slovenia, since it is rather common in the Škocjanski zatok Nature Reserve, where it forms organogenic formations.
