Opis:: Research on the structure of sediments was carried out in 2015 in the river Krąpiel and its tributaries. The main objectives of this study were to classify the types of sediments with grain size analyzing according three different criteria, as well as influence of the substrate on the abundance and diversity of macrobenthic organisms, and to determine the quality of the ground for natural breeding of salmonids. It was found that according to Polish standards, bottom sediments of the Krąpiel river and its tributaries belong to the coarse – gravel type or sandy – gravel type, whereas according to the method used in Anglo-Saxon countries – these are sandy sediments. It was also shown that the grain size of bottom sediments of the Krąpiel river and its tributaries determine friendly living environment for macroinvertebrates and for breeding salmonids.

Opis:: 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.

Opis:: This paper presents the results of a detailed comparative description of the morphological characters of N. integer obtained during eight research seasons in 2006–2007 period from the region stretching from Świnoujście to Darłowo. An attempt was made to assess the suitability of the studied characters for establishing to which populations individuals belong, to identify secondary sex traits and to detect differences in the body shape of these shrimp-like crustaceans. Most of the measurable characters in all of the samples discrimination analysis indicated the characters which differentiated the compared groups were telson length, lower abdomen width, exopodite uropod length, cephalothorax width below the carapace, cephalothorax width above the carapace and the height of fourth and fifth abdominal segment connections.

Opis:: The results of hydrochemical tests of the Gwdy river in the area of the town of Piła are presented in this study. The catchment area of the Gwda river comprises the area of 4942.8 km². The surface of catchment area is covered with forest in 43.1%, arable land constitutes 36.5%, and grassland 7.2%. The Gwda river is a right-bank tributary of the Noteć River of IV order. Water samplings were collected in 2009 from three measurement and control points located between 13 and 24 kilometre of the course of the river. During the tests thermal and oxygen conditions were marked and biogenic substances (nitrate acid, ammonia nitrogen, nitrite nitrogen, total nitrogen, total phosphorus and mineral phosphorus). Concentrations of most of the indicators examined qualified the waters of Gwda to the waters of good quality. The indicator whose concentrations exceeded the limit values for the waters of quality was general phosphorus.
