Tourism pressure on protected areas with attractive landscapes leads to environmental modifications. Eutrophication poses the main threat quality of water in alpine lakes. Even small inflows biogenic elements can disrupt ecological balance these ecosystems. The aim this study was verify hypothesis that recreational activities and easy access lakes contribute changes their status. This verified by analyzing presence hydromacrophytes two Tatra National Park (Poland). analysis carried out along...
SUMMARY 1. A biomanipulation experiment was carried out in a small (10 ha), but relatively deep (17 m) and highly eutrophic lake northern Poland. The had been stocked 1996, 1997 1998 with variety of piscivorous fish (pike, catfish, trout pikeperch), order to reduce numbers cyprinid planktivores. 2. Piscivore stocking associated threefold decrease the offshore density (night echosounding). Despite this reduction, large planktonic cladoceran, Daphnia hyalina , remained scarce, whereas...
Parasitological studies of fish from Lake Kortowskie were carried out 2001 to 2004. In the current study, 381 representing ten species: perch, Perca fluviatilis L., bleak, Alburnus alburnus (L.), ruffe, Gymnocephalus cernuus silver bream, Abramis bjoercna pike, Esox lucius common gudgeon, Gobio gobio tench, Tinca tinca rudd, Scardinius erythrophthalmus brama (L.) and roach, Rutilus rutilus examined. The aim study was review parasites selected species compare infestation rudd in 1984-88, 1994...
In 2000 and 2001, larval vendace, Coregonus albula (L.), were marked released into Lake Wigry. The larvae immersed in alizarin red S. Of the 19.2 million vendace 2000, 2 (10.4% of overall number fish released), 2001 18.8 released, 7 (47.8%). subsequent years, otoliths excised from caught them with marks was determined. It assumed that all unmarked specimens came equally natural spawning stocking assuming survival is equal both forms recruitment. confirmed 82.4% generation originated...
The aim of the study was to determine age and length growth rates vendace, Coregonus albula (L.), from Lake Wigry (northeastern Poland). Fish were captured 2001 2005 in months August September. most frequent group catches 2+, which comprised 53% all fish caught. Growth determined using Dahl-Lee Rosa Lee back-calculation methods. These basis for calculating mathematical rate models. that best corresponded with empirical data calculated a second-degree polynomial model based on...
The aim of the study was to determine prevalence Cottus poecilopus in main streams Tatra National Park Poland. Fishing research conducted within summer and autumn 2014 for fourteen streams. catches were made with pulse fishing device (IUP-24) wading up stream. During caught fishes have been characterized habitat has by noting speed current, presence obstacles hiding places fish, width, type size bottom substrate, wood shade. beginning end each transect described geographic coordinates using...

Abstract Lake Ostrowite is a mesotrophic lake in Northern Poland 280.7 ha area and 43 m deep at its deepest point. To study vendace ( Coregonus albula L.) diet the lake, fish zooplankton were sampled two stations on 28-29 April, 15-16 May (fish only), July August 2004. Fish caught by gill netting, while was collected from whole water column means of Ruttner sampler (5 x 2 dm 3 ). In total 91 specimens analysed, which 64.8% had non-empty alimentary tracts. April samples Copepoda most numerous...
