Seasonal and daily changes in the fish community and variations between commercial and non-commercial fish abundance were monitored in the inshore waters of the western part of the Gulf of Gdask (the Sopot territory). Samples were collected from December 1998 to December 1999, though monthly samplings, and supplemented by 24-hour investigations taken every three months, using a two-meter wide trawl. Among the 16 species collected, 5 were commercial and 11 were non-commercial. Juvenile forms of herring and flounder dominated the commercial fish; the highest catches were in March (89 ind. 100 m-2). Among the non-commercial fish, two species of Gobiidae (sand and common goby), and three-spine stickleback were most frequently caught. During the 24hour observations, commercial fish were noticed mostly at night. The investigated area is an important zone for both juvenile commercial fish and some ecologically important uncomercial species.

Presence of fish from 10 species was confirmed in shallow close to shore waters on the tip of the Hel Peninsula, in period from early spring to late autumn. Zone from shore to 5 meter depth was investigated. The highest number and biomass were noticed in summer on 3 meter depth. As general biodiversity taking into account number increases with increasing depth, whereas biodiversity taking into account biomass is not so depth dependent. Flounder is the absolute dominant at all depths in investigated region. Common goby and three spined stickleback are two other significant species. Comparison of data from all investigated depths shows that sampling in the most close to shore zone (1 meter depth) let well describe fish community of near shore shallow waters in investigated area.
