UDK: 597:576.89(497.6) (282.249) The prevalence and intensity of trematodes ectoparasites in freshwater fish are presented in this paper. Parasitology researches were conducted during 2017 in the middle course of the river Sava near Orašje. All results from this study were tested with the use of nonparametric tests (χ2, Kruskal-Wallis test and Spearman test of corellation) in the statistical package STATISTICA 7. The total of 400 sampled specimens of different fish species were parasitologically tested. The trematodes from the class Monogenea (Dactylogyrus, Gyrodactylus and Eudiplozoon nipponicum) and Digenea (Posthodiplostomum cuticola) were found on the skin and the gills of the fish. The genus Dactylogyrus was found on 27 specimens, or 6.75%. Intensity of the infection for the genus Dactylogyrus did not show any significant deviations during different seasons. Parasites from the genus Gyrodactylus were found on the skin and the gills of 40 infected specimens, dominantly found on the gills. The species Eudiplozoon nipponicum was found in low prevalence in the total ichthyo sample of 1.75%. The presence of the species Posthodiplostomum cuticola is established in 18 specimens and the prevalence of the infection in total sample was 4.5%.

Abstract Distributional range of freshwater blenny Salaria fluviatilis extends to the tributaries along the Mediterranean and Black seas. It is considered endangered in several Mediterranean European countries. Although previously mentioned in the lists of freshwater fish species, its presence has never before been confirmed in Bosnia and Herzegovina. Consequently, this has led to doubts about its distribution there. A sample specimen of freshwater blenny was obtained from the lower Neretva River (Adriatic Sea watershed) in Bosnia and Herzegovina in May 2020, representing the first reliable record of this species. Considering that this record confirms older reports, however, it seems that earlier surveys have failed to locate the fish. Knowledge of the composition of fish species in river basins and updating their list are among the important requirements for managing the biodiversity of each country, as well as water and fish resources.

The Relationship

Background: The research objective of the study is to determine the differences in the manifestation of the motor status of normally fed preschool test subjects, classified into groups according to foot status. Methods: This is a simple, comparative observational study. Preschool children included in this study have been subjected to anthropometric measurements in order to determine BMI, tests for motor skills assessment (running at 20 m from a high start, standing broad jump, backwards polygon, rectangular seated forward bend, plate tapping, sit-ups for 60 s, and bent arm hang), and a determination of foot status. The total sample was comprised of 202 test subjects who attended a regular sports program, aged 3.9 to 6.5 years of decimal age (M = 141; Age = 5.3 ± 0.74; Height = 117.3 ± 7.1; Weight = 22 ± 3.7; F = 61; Age = 5.1 ± 0.73; Height = 114.9 ± 7.4; Weight = 21.2 ± 3.8), of which 153 (75.7%) were normally fed, 6 (3%) were undernourished, 30 were overweight (14.9%), and 13 were obese (6.4%). Results: In the total sample, 30 (14.9%) subjects had normal arch feet, 90 (44.6%) high arched feet, and 41 (20.3%) flat feet. We found 41 (20.3%) subjects who had different left and right foot statuses within this sample. The data were processed by means of nonparametric tests (the Kruskal–Wallis and Mann–Whitney U tests) at a significance level p ≤ 0.05. Conclusion: The results show that there is a statistically significant difference between groups of subjects with different foot statuses in the manifestation of motor status in most tests, with a significance level of p ≤ 0.01, and in tests of sit-ups for 60 s and the bent arm hang, there is a statistically significant difference, the level of which is p ≤ 0.05. It is only in the inclination test of rectangular seated forward bend that no statistically significant difference was displayed.
