In the years 1993-1995, investigations of the variability in occurrence of gobiids in the shallowest part of Puck Bay (0-1 m depth) were conducted. Three species of gobiids, Pomatoschistus minutus, Pomatoschistus microps and Neogobius melanostomus were identified. Abundance, biomass and species distribution varied with time and sampling location. P. microps was a dominant species all year round and accounted for over 80% of all fish caught. An apparent preference of P. microps for inhabiting the internal part of Puck Bay was observed while P. minutus was found more frequently in the external part of Bay. In the coastal zone, fish from genus Pomatoschistus showed seasonality of occurrence with the abundance peak in the fall.
