| Pomeranian Bay basin is a coastal area convenient for the reproduction of many fish species, including herring. The goal of this work was to evaluate the differences in larval herring distribution in the Pomeranian Bay area in years 1992-98 and 2007-2011. In both periods the herring larvae samples were collected between April and July at up to 10 stations located in all years in the same area. The mean density (from all stations on the most abundant sampling day) in different years varied from 41 to 973 ind.100 m-3, with the maximum numbers observed usually in the second half of May. Significant difference in larvae abundance between years 1992-98 and 2007-2011 were compared to differences in the distribution, especially of small larvae (<10 mm SL) that provide indication of spawning sites.
Key words: Pomeranian Bay, herring larvae, abundance
