Spatial (depth dependent) and temporal distribution of fish in sandy eulittoral of the tip of the Hel Peninsula (the Gulf of Gdansk - Baltic)
Languages of publication
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.
