The subject of this study was the analysis of determinants and functioning of farm tourism in the communes of the Wieprza River basin. There was performed the analysis of determinants of farm tourism development in the area of communes located in the Wieprza River basin and characteristics of functioning of farm tourism in agritourism farms in the studied area along with the analysis of selected features of tourist traffic on the basis of field research that had been carried out.

The subject of the study were changes in land use over the last 400 years, including forest areas. The research covered the area, the range of which is determined by the basins of three small left-bank tributaries of the Wieprza River and its direct catchments (Northern Poland). The analysis included selected historical sources and, above all, maps issued in the years 1618-2008. It was found that in the studied area the border between forest and non-forest areas was established in the Middle Ages and subsequent changes in its course were of evolutionary nature. Until the midnineteenth century there was significant decline in forest area, which was related to the acquisition of areas mainly for arable fields as well as meadows and pastures. Subsequent changes of forest areas, studied for periods 1836-1934 and 1934-2008 were relatively small, but they were accompanied by significant modifications of the forest species composition. Relatively the biggest changes in the last distinguished period included built-up areas with orchards, where a decrease in occupied areas of almost 25% was noted.

The signal crayfish Pacifastacus leniusculus (Dana, 1852) of North American origin was introduced to Europe (to Scandinavia) in the 1960s. Since that time due to translocation to many countries, biological features and ecological plasticity, it became widespread, invasive and displaced native species. The paper reports first multi- point colonization of P. leniusculus in the Polish rivers. The aim of the study was to determine the current distribution of the signal crayfish in the coastal Baltic tributary (the River Wieprza) after 20 years of deliberate releases in its drainage area. During sampling at 28 sites with use of the “Pirate” crayfish traps and hand collection methods in spring and summer 2014, 127 P. leniusculus individuals were found at 8 sites in the Wieprza and its two tributaries, both away from and close to known sites of their introduction in 1995 and 1996 in the Wieprza River drainage area. The species spreads via the Wieprza River towards the Baltic brackish waters. With such expansion of this species, it is expected to be found in Polish coastal waters of the Baltic Sea and in other coastal rivers in the near future. The conflict between legal aspects of the signal crayfish farming, colonization by the species of the natural aquatic ecosystems and the expectations of consumers is discussed.

The aim of the paper is the evaluation of the surface runoff impact on chemical composition of waters, transport of suspension and dissolved substances out of the catchment in two left-bank tributaries of the lower Wieprza River – Potok Starokrakowski and Jarosławianka. During the flood discharges were several tens times higher than the average recorded in that period. In Potok Starokrakowski the discharge was 500 dm³/s (typical discharges 10-20 dm³/s) and in Jarosławianka 1500 dm³/s (typical discharges 10-40 dm³/s). The rapid increase in discharge in the streams caused activation of suspension transport in both catchments. In Potok Starokrakowski the suspension content in the flood period was 56.5 mg/dm³, while in Jarosławianka 160.3 mg/dm³. In the flood period, a considerable decrease in the concentration of some dissolved substances, including Na+, Ca2+, Mg2+ and Cl-, was observed. Simultaneously, an increase in the concentration of ammonium nitrogen (NH4-N), potassium, total organic carbon and Kjeldahl’s nitrogen (NK) was observed in both streams. Observed flood had huge meaning in suspended and soluted substances transport out of both catchments.

The measurements of chemical components in water of Wieprza River showed that water of this river in 2002-2003 was characterised by the high purity. The average values of most indexes were contained in the ranges of standards for the first purity class. Nevertheless considerable increase of investigation parameters was observed in zone of sewage-treatment plant and uncontrolled waste dump. The part of flow downing pollutions were absorbed by peat soils. Kępice town bring into Wieprza River the load of organic matter miscalculating to BOD5 average 133 kg O2 d-1 (85 t O2 y-1), the load of nitrogen 140 kg N d-1 (51 t N y-1) and phosphorus 18 kg P d-1 (6.2 t P y-1). However Wieprza River shows high self-purification ability. The level of investigation components in this river (4 km outside of the Kępice town) returned to the level which was 2 km before the town.

The study focused on the eel (length and weight averaging 23.1 cm and 13.7 g, respectively) ascending Pomeranian rivers in summers of 1999-2003. The swim bladder was examined in 322 individuals, the intestine being examined in 272 fish. Anguillicola crassus was present in the swim bladder of 184 fish. Infection prevalence varied between the rivers, the highest prevalence being recorded in the eel caught in the Radew (65.6%) and the lowest in the Wieprza (41.7%). The intensity of infection was generally low, the mean values varying from 2. l in the Rega to 1.3 in the Wieprza. The coefficient of infection was low (0,11 to 0,12). Spinitectus-inermis was present, with low intensity, in the intestine of 18 fish (6.6%). The nematode had not been recorded in the eel in Poland for 70 years. In addition, the intestine of the eel under study was found to house Raphidascaris acus and Paraquimperia tennerima, each present as a single larva. This is the first record of the latter in Poland. The infection of eel from the Radew river that stayed in the fresh water for a longer time was higher than that of the eel found in the Rega and Wieprza.
