Lakes provide different ecosystem services, including those related to tourism and recreation. Sustainable development principles should be respected in lake tourism planning. The aim of this study was to assess the impact of tourism on the lakeshore zone in a typical post-glacial Lakeland in Northern Poland (Central Europe). An explanatory analysis of the distribution of individual spatial factor values was performed using the SHapley Additive exPlanations algorithm (SHAP). In a first step, the aim was to select a Machine Learning model for modelling based on Shapley values. The greater or lesser influence of a given factor on the tourism function was measured for individual lakes. The final results of ensemble modelling and SHAP were obtained by averaging the results of five random repetitions of the execution of these models. The impact of tourism on the lakeshore zone can be much more accurately determined using an indirect method, by analysing the tourism and recreational infrastructure constantly present there. The values of the indices proposed in the study provide indirect information on the number of tourists using the tourist and recreational facilities and are a measure of the impact of tourism on the lakeshore zone. The developed methodology can be applied to the majority of post-glacial lakes in Europe and other regions of the world in order to monitor the threats resulting from shore zone exploitation. Such studies can be an appropriate tool for management and planning by the relevant authorities.

Changes in land use and land cover (LU/LC) are one of the main contributors to global change. The fall of the Iron Curtain in 1989 resulted in massive socio-economic and institutional transformations that triggered changes in the LU/LC. The paper analyses the processes of land use/cover change in the shore zone of 145 lakes of the Olsztyn Lakeland in north-eastern Poland based on GIS data sets over a period of 30 years. This is a new approach aimed at analysing qualitative, quantitative and spatial changes in the shore zone of lakes related to socio-economic transformation in Poland. A very large decrease in agricultural land area was noted, which is currently an economically marginal class of land use in the shore zone of lakes. The decrease in the agricultural land area was related to a significant increase in the residential construction development and the process of afforestation. While the conversion of agricultural land was a positive phenomenon from the environmental point of view, the main threat to the shore zone of lakes was the expansion of settlement. Our results also showed a negative correlation between the surface of urban areas and the surface occupied by tourist accommodation facilities. This fact indicates a cross functional conflict between the settlement and tourism functions of the area in the lake shore zone. The results also indicate that the changes in the tourist accommodation base were mainly of a qualitative and spatial nature. This is probably due to a change in tourist preferences in terms of accommodation standards.

The purpose of this study was to analyse the influence of water salinity on the incubation of eggs and growth of the larvae of sichel Pelecus cultratus (L.) under controlled conditions. The following water salinity was considered: 3, 6, 9, 12, 15 and 0 ppt for the control. The eggs incubation time depended on the water salinity, lasting from 56.3°D [9 ppt] to 107.7°D [0 ppt]. The higher water salinity, shorter the incubation time. The highest survivability of larvae was obtained in water of the salinity equal 3 ppt and in freshwater, where respectively 87% and 84% of the larvae survived. No hatched larvae were obtained in water of the salinity of 12 and 15 ppt, as all embryos died during the experiment. Larvae were reared up for 21 days. The final body weight, depending on the water salinity, reached from 43.5 mg [9 ppt] to 74.6 mg [3 ppt], at the respective body lengths of 19.3 mm and 23.2 mm. The highest body gains and lengths of larvae were observed in water of the salinity of 3 ppt. The lowest survivability of sichel larvae occurred in water of the salinity 9 ppt, where it was only 53.2%. The survivability of larvae in freshwater and water of the salinity of 3 ppt was quite similar: 96.2% and 95.6% respectively. Water salinity degree of 12 and 15 ppt appeared to be lethal for both embryos and larvae of the sichel.

The ontogeny of the digestive tract was studied histologically in burbot, Lota lota L., from hatching to 42 days post-hatch (dph). At hatching, the digestive tract consisted of a straight tube with discernible digestive accessory glands (the liver and the pancreas) dorsally attached to the yolk sac. Most of the yolk sac reserves were consumed during the first 12 days and were completely depleted by 17 dph. The first PAS-positive goblet cells appeared at 6 dph, dispersed within the epithelium of the oesophagus and increasing substantially in number and distribution as development progressed. At 12 dph, the first vacuoles (neutral lipids) appeared in the intestine, indicating the functional absorption of nutrients from food. Differentiation of gastric glands was first noticed at 17 dph and was extensive by 27 dph. L. lota larvae have a morphologically complete digestive tract by 32 dph. These findings on the development of the digestive system in L. lota may contribute to a better understanding of its ontogeny and can be useful for improvement of the larval rearing techniques of this promising species for freshwater aquaculture diversification.

Morphology of hybrids between the goldfish (Carassius auratus) and common carp (Cyprinus carpio) are studied by biometric and meristic methods. Additionally, histological analyses concerning gonads as well as genetic characteristics of chromosomes are performed. Studied hybrids were morphologically very similar to a goldfish but possessed one pair of reduced posterior barbels. Most meristic and biometric indices had intermediate values when compared to parental species. Histological study showed that investigated hybrids produce gonads with germ cells. All studied males had gonads at the same stage of maturity (III stage). By contrast, female gonads were in various stages of development – from sexually immature to post-spawning stage. Karyotype characteristics were assessed in terms of chromosomes number, fundamental arm number and location of nucleolus organizer regions (NOR). The data obtained were compared with baseline karyotypes of species used for hybridization, based on information from the literature. The diploid chromosome number of studied hybrids equaled 2n = 100, NF = 152. Ag-NORs were localized on the short arms of two to three submetacentric chromosomes. Additionally, one to two supernumerary (B) chromosomes were also found, which is a typical phenomenon for interspecific hybrids, especially between cyprinid fish species.

This study analyzed the influence of temperature on the rearing of sichel Pelecus cultratus larvae under controlled conditions. Five constant temperature regimes were tested: 14 °C, 18 °C, 22 °C, 26 °C and 30 °C. The larvae were reared for 30 days in aquaria with 50 dm3 working capacities. The larvae density was 40 individuals/dm3 and the fish larvae were fed live artemia nauplii. The assessment of the effect of thermal conditions during the rearing period on fish was based on the final size of fish, increment in the total length, relative growth ratio, survivability and condition (the Fulton index). At the end of the 30-day rearing period, it was determined that the largest larvae had been obtained in the 30 °C water (average weight 374.2 mg with average length 43.1 mm). The smallest larvae grew in the coldest water (14 °C), where their average weight was 32.2 mg with an average length of 19.4 mm. No negative effect of temperature was observed on the survivability rate of reared larvae, which oscillated around 91 ± 5 %. Sichel larvae are characterized by high tolerance and high survivability when reared in high-temperature water.

The chromosomal characteristics, locations and variations of the C-band positive heterochromatin and telomeric DNA sequences were studied in the European grayling karyotype (Thymallus thymallus, Salmonidae) using conventional C-banding, endonucleases digestion banding, silver nitrate (AgNO3), chromomycin A3 and 4′,6-diamidino-2-phenylindole staining techniques as well as fluorescence in situ hybridization (FISH) and primed in situ labelling. Original data on the chromosomal distribution of segments resistant to AluI restriction endonuclease and identification of the C-banded heterochromatin presented here have been used to characterize the grayling karyotype polymorphism. Structural and length polymorphism of the chromosome 21 showing a conspicuous heterochromatin block adjacent to the centromere seems to be the result of the deletion and inversion. Two pairs of nuclear organizer regions (NOR)-bearing chromosomes were found to be polymorphic in size and displaying several distinct forms. FISH with telomeric peptide nucleic acid probe enabled recognition of the conservative telomeric DNA sequences. The karyotype of the thymallid fish is thought to experienced numerous pericentric inversions and internal telomeric sites (ITSs) observed at the pericentromeric regions of the six European grayling metacentric chromosomes are likely relics of the these rearrangements. None of the ITS sites matched either chromosome 21 or NOR bearing chromosomes.

Feeding and food selection of burbot (Lota lota L.) larvae reared in illuminated cages were studied. The experiment was carried out in mesotrophic Lake Maróz, in north-eastern Poland, for 6 weeks in two successive years. The initial stocking density was 1,250 larvae (20 DPH) per cage. Food selection according to the zooplankton groups (Rotifera, Cladocera and Copepoda) and length classes was expressed by the Strauss linear selectivity index (L). Zooplankton species composition in the lake was similar in the two seasons of the study and organisms shorter than 0.5 mm prevailed in the plankton. The mean number of prey found in burbot alimentary tracts increased from about 40 up to over 200 during the course of the study. A very large inter-individual variation in the amount of food organisms consumed by fish was noted. Analysis of the values of the Strauss food selectivity index shows that at the beginning of the first year of the experiment, burbot larvae preferred copepods, most numerous in the environment at that time; later, fish tended to select cladocerans. In the second year of the study, fish more often ate copepods, irrespective of their quantities in the environment. During the whole study, reared burbot larvae did not eat rotifers, even when they were numerous in cages. Similarly to the rotifers, the smallest planktonic organisms, measuring up to 0.5 mm in length, were typically neglected by fish, while the 0.6–1.0 mm group was most frequently selected. There were also considerable individual differences between particular burbot specimens in their food preferences.

During the last 10 years, the stickleback has emerged as a promising model system in several biological fields. In particular, it is one of the most investigated fish groups by evolutionary biologists, as a model for understanding the genetic and molecular basis in processes of adaptive radiation, microevolution and development, as well as the genetic basis of sex determination. To provide karyological information about stickleback fish we performed cytogenetic analysis of the threespine stickleback (Gasterosteus aculeatus L.) and the ninespine stickleback (Pungitius pungitius L.). Diploid chromosome number in both species equalled 42; however, the chromosome arm numbers were 62 and 70, respectively. In the threespine stickleback, multichromosomal location of silver (AgNO3) and chromomycin A3 (CMA3) positively stained Nucleolar Organizer Regions (Ag/CMA3-NORs) was observed. The number of silver-stained chromosomes varied among different individuals from two to six. The Ag/CMA3-NORs covered almost entire short arms of one pair of middle-sized submetacentric chromosome pairs in the ninespine stickleback. In one male, the only Ag-NOR was situated telomerically on the long arm of the Y chromosome. The 5S rDNA clusters were observed on short arms of one pair of subtelocentric chromosomes in the threespine stickleback and four pairs of subtelo-acrocentric chromosomes in the ninespine stickleback of both sexes. Chromosome rearrangements responsible for the stickleback karyotype polymorphisms did not leave any internally located telomeric sequences. The results obtained in two stickleback species are therefore of considerable interest and further karyological studies should be carried out on the other populations of the wide species range in order to provide a more general picture of karyoevolutive trends in Gasterosteidae.

Feeding during the development of Eurasian perch (Perca fluviatilis) larvae was studied in situ in cylindrical cages. Initially perch larvae were maintained in cages, 0.2 mm of mesh size. The initial stocking density was 7 000 larvae per cage. Fish were fed with Zooplankton and after 17 days were transplanted to cages with a larger mesh size (1.2 mm). Development was observed for additional 17 days. Larval survival was about 25% and 65% for the initial and secondary rearing, respectively. Perch larvae ate initially rotifers and later ate nauplii and copepodites. Cladocera was the dominant food item in the diet of perch at the conclusion of our observations.

Feeding habits of larval pike, Esox lucius L., was studied at three stocking densities in illuminated cages. Developmental patterns of larval feeding on Zooplankton were independent of larval density. During the first week of rearing, larvae fed mainly on rotifers, small cladocerans, nauplii and copepodites of Cyclopidae. After second week they selected small cladocerans (Bosmina spp.), and adult copepods (Cyclops and Mesocyclops spp.). Higher stocking densities resulted in lower survival and growth rates. This was presumably due to increased competition for food, as the composition of the diet was independent of stocking density.
