ABSTRACT
The aim of the study was to determine the biological characters typical of Neomysis integer, to investigate and update issues of its biology, ecology, and distribution in the southwestern Baltic Sea, and to compare biological properties of N. integer collected during eight study seasons in 2006–2007 in the region from Świnoujście to Darłowo. No link was established between N. integer size and sample collection site. The population attained sizes within the range of 2.64 to 18.84 mm. The size at which females achieved sexual maturity varied seasonally. A mean of 34 eggs was noted in the marsupium. The mean wet weight of N. integer was 0.011 g. Three generations were confirmed at most of the study sites.
