    Early juvenile tubenose goby Proterorhinus semilunaris were collected in nocturnal pelagic waters of the Vranov Reservoir, Czech Republic, in July 2008. Diet analysis demonstrated that juvenile P. semilunaris were feeding on zooplankton, mainly Leptodora kindtii. However, benthic prey was found in the digestive tracts of 55 % of these fish, indicating that early juveniles migrated to the open water either from the bottom or littoral habitats. This is the first time that utilisation of limnetic environment has been documented in P. semilunaris.
