fatty acid composition of the muscle lipids of five fish species in işıklı and karacaören dam lake, turkey.	total fatty acid composition of muscle lipids in some fish species (cyprinus carpio (işıklı dam lake), tinca tinca (işıklı dam lake), scardinius erythrophthalmus (işıklı dam lake), cyprinus carpio (karacaören dam lake), and carassius carassius (karacaören dam lake)) was determined by gas chromatography. polyunsaturated fatty acids (pufas) of cyprinus carpio (işıklı dam lake) were found higher than pufa of other species. palmitic acid was the highest saturated fatty acid (sfa) in tinca tinca (24. ...	2014	25143856
retrograde positive contrast urethrocystography of the fish urogenital system.	the radiological differences between the urinary tract of dicentrarchus labrax, sparus aurata, tinca tinca, and cyprinus carpio are shown. in fresh water teleosts the urinary bladder is sigmoid and a short urethra leads to the urinary pore. genital and anal pores are present. in sparus aurata the urinary bladder has a globoid shape. in dicentrarchus labrax the urinary bladder is smaller and elongate. in both marine teleosts a single urogenital pore is visible. positive contrast was used to surv ...	2014	25180198
fine structure and cellular responses at the host-parasite interface in a range of fish-helminth systems.	a series of ultrastructural-based studies were conducted on the interface region in different fish-helminth systems: (a) an intestinal infection of the cestode monobothrium wageneri in tench, tinca tinca; (b) an extensive intestinal submucosa and mucosal infection in tench by metacercariae of an unidentified digenean trematode; (c) an intestinal infection in brown trout, salmo trutta, by the acanthocephalan dentitruncus truttae; (d) an extraintestinal infection by larvae of the acanthocephalan, ...	2015	25613477
biomass and abundance biases in european standard gillnet sampling.	the european standard en 14757 recommends gillnet mesh sizes that range from 5 to 55mm (knot-to-knot) for the standard monitoring of fish assemblages and suggests adding gillnets with larger mesh sizes if necessary. our research showed that the recommended range of mesh sizes did not provide a representative picture of fish sizes for larger species that commonly occur in continental europe. we developed a novel, large mesh gillnet which consists of mesh sizes 70, 90, 110 and 135mm (knot to knot, ...	2015	25793776
quantification of histamine in various fish samples using square wave stripping voltammetric method.	the objective of this study was to describe a new and simple method for the determination of histamine so that it can be used in routine food analysis. a square wave stripping voltammetric (swsv) method has been used for the indirect determination of histamine. the method is based on accumulation copper (ii) - histamine complex onto a hanging mercury drop electrode and reduction of complex. the optimum conditions include an accumulation potential of -420 mv (versus ag/agcl), an accumulation time ...	2015	26396415
weighted species richness outperforms species richness as predictor of biotic resistance.	the species richness hypothesis, which predicts that species-rich communities should be better at resisting invasions than species-poor communities, has been empirically tested many times and is often poorly supported. in this study, we contrast the species richness hypothesis with four alternative hypotheses with the aim of finding better descriptors of invasion resistance. these alternative hypotheses state that resistance to invasions is determined by abiotic conditions, community saturation ...	2016	27008794
cryosurvival of isolated testicular cells and testicular tissue of tench tinca tinca and goldfish carassius auratus following slow-rate freezing.	experiments were carried out to test the efficiency of cryopreservation of whole testicular tissue in tench tinca tinca and goldfish carassius auratus and compare it to cryopreservation of isolated testicular cells. additionally, effects of three cryoprotectants (dimethyl sulphoxyde - me2so, methanol - meoh and ethylene glycol - eg) at three concentrations (1m, 2m and 3m) on post-thaw cell viability were assessed. tissue pieces/isolated testicular cells were diluted in cryomedia and cryopreserve ...	2017	27401260
characterization of sections of the sava river based on fish community structure.	sampling was undertaken, with the same fishing gear and along the sava river, from its source to its confluence, in september 2014 and september 2015. in total, 44 fish species were identified, of which 37 were native species and 7 were alien. fish samples revealed independence in terms of both species composition and their abundance under different hydrological conditions. during flooding and high water levels in 2014, pelagic fish species were sampled in greater proportion than at lower water ...	2017	27639023
protective responses of intestinal mucous cells in a range of fish-helminth systems.	histopathological, immunofluorescence and ultrastructural studies were conducted on the intestines of four fish species infected with different taxa of enteric helminths. brown trout (salmo trutta trutta), eel (anguilla anguilla) and tench (tinca tinca) obtained from lake piediluco (central italy) were examined. brown trout and eel were infected with two species of acanthocephalans, and tench was parasitized with a tapeworm species. in addition to the above site, specimens of chub (squalius ceph ...	2016	28026022
occurrence of parasites of the genus eustrongylides spp. (nematoda: dioctophymatidae) in fish caught in trasimeno lake, italy.	eustrongylides spp. is considered a freshwater fish zoonotic nematode. in the present study, the prevalence of eustrongylides spp. in six edible fish (european perch - perca fluviatilis, goldfish - carassius auratus, largemouth black bass - micropterus salmoides, tench- tinca tinca, carp - cyprinus carpio and sand smelt - atherina boyeri) of trasimeno lake was surveyed. the investigations were conducted from october 2014 to september 2015 and 384 specimens per species for each season were caught ...	2016	28058245
encountering a bait is necessary but insufficient to explain individual variability in vulnerability to angling in two freshwater benthivorous fish in the wild.	fish personality traits, such as swimming activity, or personality related emergent behavioural properties, such as the degree of space use shown by an individual fish, should affect encounter rates between individual fish and fishing gear. increased encounters should in turn drive vulnerability to capture by passively operated gears. however, empirical evidence documenting a relationship between activity-based behaviours and vulnerability to capture by passive fishing gear in the wild is limite ...	2017	28301558
fish predation and offspring survival in the prosobranch snail viviparus ater.	in this study we identified some of the predators of the freshwater snail viviparus ater and estimated offspring survival to the end of the first summer in a natural population. newborn v. ater were eaten by the fish barbus barbus, rutilus rutilus, scardinius erythrophtalmus and tinca tinca. out of 137 guts of abramis brama caught in lake zürich 1 contained shell fragments and an operculum of a newborn v. ater. on a 40×40 m grid near goldbach, lake zürich, we counted 678 adult females of v. ater ...	1993	28313816
