    Opis:
    Praca zwiera przegląd aktualnych informacji na temat stanu zasobów węgorza europejskiego Anguilla anguilla (L.), wliczając obligatoryjne wskaźniki biomasy i śmiertelności raportowane do Komisji Europejskiej w ramach wdrażania planów gospodarowania zasobami węgorza oraz wartość indeksu rekrutacji. Przedstawiono środki gospodarowania zapisane w Polskim Planie Gospodarowania Zasobami Węgorza oraz w państwach poławiających węgorze migrujące z dorzeczy leżących na terytorium Polski. Najnowsze dane wskazują na zły stan zasobów w większości państw członkowskich raportujących wskaźniki biomasy, jednakże efektów wdrożenia rozporządzenia 1100/2007 w postaci zwiększonego spływu węgorzy srebrzystych możemy się spodziewać po upływie jednego pokolenia węgorzy (średnio 10 lat) w wodach śródlądowych.
    The paper contains an overview of current information on the status of the European eel Anguilla anguilla (L.), including obligatory indicators of biomass and mortality rates reported to the European Commission within the framework of implementation of the Eel Management Plans, as well as the value of the recruitment index. Management measures described in the Polish Eel Management Plan, and in countries fishing for eels migrating from the river basins lying on the Polish territory were presented. The most recent data indicate the poor state of resources in the majority of Member States reporting indicators of biomass, but the effects of implementation of Regulation 1100/2007 in the form of increased silver eel escapement can be expected after one generation of eels (average 10 years) in inland waters.

    Opis:
    The abundance of the eel (Anguilla anguilla) in Europe has been on the decline in recent years, to the extent that this fish species is now considered to be threatened with extinction. Hence, the current implementation of the Eel Management Plan in Poland, whose aim is to restore w stocks of this fish. The main natural habitats of eel are the transitional waters of the Vistula and Szczecin lagoons and lakes in northern Poland. The eel is highly valued by many consumers for the taste and texture of its meat. The aim of the study was to determine differences in concentrations of macro- and microelements and toxic metals in muscles of the eel as a function of each specimen’s length, mass and the origin. The results of the study also served an evaluation of the health benefits and risks to consumers of eel meat with regard to the content of macro- and microelements and toxic metals. Specimens of the eel (Anguilla anguilla) were caught in 2011-2013, in five regions of Poland: the southern Baltic, inland lakes in northeast Poland, the Vistula and Szczecin lagoons, and in the Vistula River. The concentrations of Ca, P, Mg, Na, K, Fe, Sr, Zn and As were determined with optical emission spectrometry. The flameless atomic absorption spectrometry method was used to measure concentrations of Cu, Cd and Pb. The content of Hg and Se were determined with atomic absorption, those of mercury with cold vapour, and of selenium with hydride generation. The concentrations of macro- and microelements in most instances, with the exception of P and Zn, were negatively correlated with the eel’s length and mass, which indicated that small fish contained more minerals than large specimens. The eel is a rich source of phosphorus, zinc, selenium and iron, and it can supply significant quantities of the daily requirements of human consumers for these minerals. The other minerals occurred in eel muscle at levels that ranged from 2 to 6% of human daily requirements. Among the toxic metals, mercury was the cause for concern, while cadmium and lead occurred at low levels in all of the specimens examined regardless of their size. The mean concentration of mercury ranged from 0.147 to 0.273 mg kg-1 and was positively correlated with specimen length and mass. The content of mercury in large eel exceeded 0.500 mg kg-1, while small eel (up to 70 cm) contained lower levels of mercury. Large eel exceeding 70 cm can pose a threat to the consumer’s health because of mercury, and especially its organic from of methylmercury. This is why consumers should limit long-term consumption of larger eel, while it is safe to consume smaller specimens since they contain less mercury and more minerals than do large eel.

    Within 2001-2002 a total of 621 eel Anguilla anguilla (L., 1758) (488 from the Vistula Lagoon and 133 from the Puck Bay) were examined. Fifteen parasite taxa were recovered: Pseudodactylogyrus anguillae (Yin et Sproston, 1948), Brachyphallus crenatus (Rudolphi, 1802), Deropristis inflata (Molin, 1859), Diplostomum spp., Bothriocephalus claviceps (Goeze, 1782), Proteocephalus macrocephalus (Creplin, 1825), Anguillicola crassus (Kuwahara, Niimi et Itagaki, 1974), Camallanus lacustris (Zoega, 1776), Cystidicola farionis Fischer, 1798, Hysterothylacium aduncum (Rudolphi, 1802), Raphidascaris acus (Bloch, 1779), Acanthocephalus anguillae (Müller, 1780), A. lucii (Müller, 1776), Echinorhynchus gadi Müller, 1776, and Pomphorhynchus laevis (Müller, 1776), representing Monogenea, Digenea, Cestoda, Nematoda, and Acanthocephala, respectively. Ten of these taxa occurred in the Vistula Lagoon, while fourteen were noted in the, Puck Bay. P. anguillae, Diplostomum spp., C. lacustris, C. farionis and P. laevis were not found in the lagoon eels, while B. crenatus did not occur in the bay. Anguillicola crassus was the most frequently found parasite (Vistula Lagoon: prevalence 75%, mean intensity 6.9 specimens; Puck Bay: 74.4%, and 8.3 specimens, respectively). Pseudodactylogyrus anguillae was recorded for the first time in the Puck Bay.

    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.

    Opis:
    The diversity of culturable bacteria inhabiting the Baltic sea surface waters was more divergent at a polluted location than at clean areas. The most important members of the family Enterobacteriaceae that are pathogenic to fish are the enteric redmouth disease agent, Yersinia ruckeri and two species of Edwardsiella, E. tarda and E. ictaluri, Serratia, Proteus and Citrobacter have all been implicated as potential fish pathogens. The use of pharmaceutical substances is rather limited in fish compared to mammalian therapeutics. Medicinal herbs play an alternative role to antibiotic therapy in aquaculture. Ficus species (Moraceae) leaves possess great medicinal potential for the therapy of bacterial and fungal infections and may be used as a natural antiseptic and antimicrobial agent in veterinary. Accordingly, these products can be used in aquaculture as therapeutic and prophylactic agents against fish pathogens, with antimicrobial properties. Present study aimed to investigate the in vitro antimicrobial activity of the ethanolic leaf extracts of various Ficus species against fish pathogen, Citrobacter freundii. The antimicrobial susceptibility testing was done on Muller-Hinton agar by disc diffusion method (Kirby-Bauer disk diffusion susceptibility test protocol). Our results demonstrate that various species of Ficus had mild antibacterial in vitro activity against C. freundii isolated locally from infected eel (Anguilla anguilla L.). The results proved that the extracts from F. drupacea, F. septica, F. deltoidea as well as F. hispida, F. mucuso, F. pumila, F. craterostoma exhibit a favorable antibacterial activity against C. freundii. These validate scientifically their inhibitory capacity attributed by their common use in folk medicine and contribute towards the development of new treatment options in aquaculture based on natural products. The chemical analysis of the aforementioned plant extracts should be performed to determinate their chemical composition and identify the exact phytocompounds responsible for antimicrobial activity against C. freundii. In addition, they should be subjected to pharmacological evaluations with the aim of assessing their in vivo efficacy, toxicity, potential adverse effects, interactions and contraindications. Given the increasing rate of resistance development in bacterial pathogens in aquaculture environments, medicinal plants with antibacterial properties are very important as natural resources for new active compounds.
    Zioła lecznicze odgrywają rolę alternatywnej terapii antybiotykowej w akwakulturze. Substancje biologicznie aktywne pozyskiwane z roślin mają równie dobre, a nawet bardziej skuteczne działanie w porównaniu z tradycyjnymi lekami syntetycznymi, w dodatku nie wywołują oporności drobnoustrojów, która często pojawia się podczas antybiotykoterapii. W różnych regionach świata tradycyjnie w celach medycznych stosowane są różne gatunki roślin tropikalnych, m.in. fikusy (Moraceae). Głównym celem badań była ocena wrażliwości patogenu ryb Citrobacter freundii na etanolowe ekstrakty z liści wybranych gatunków fikusów. Przeciwbakteryjne działanie ekstraktów oceniano in vitro, stosując metodę dyfuzyjnokrążkową. Nasze wyniki wskazują, że różne gatunki Ficus wykazują in vitro łagodne działanie przeciwbakteryjne przeciwko C. freundii izolowanego lokalnie z zainfekowanego węgorza (Anguilla anguilla L.). Przeprowadzone badania wykazały, że największą aktywność przeciwbakteryjną wobec szczepu C. freundii wykazały etanolowe wyciągi uzyskane z liści gatunków fikusów: F. drupacea, F. septica, F. deltoidea, F. hispida, F. mucuso, F. pumila, F. craterostoma. Wstępne badania screeningowe wskazują zatem, że wyciągi z liści niektórych gatunków fikusów o właściwościach antybakteryjnych mogą stanowić alternatywne środki terapeutyczne przeciwko infekcjom bakteryjnym w akwakulturze. Produkty te mogą być stosowane jako środki terapeutyczne i profilaktyczne, niemniej jednak powinni jeszcze zostać przeprowadzone bardzo intensywne badania dotyczące ich właściwości przeciwbakteryjnych.

    Introduction. Eel is one of the most valuable commercial fish species of the Vistula Lagoon. For this reason its infection by non-indigenous species of parasites is the subject of the interest of sciencists. Material and methods. A total of 90 eel specimens caught in the Polish part of the Vistula Lagoon were examined over the period of May-August 2005. The fish were subjected to standard procedures of parasitological examination and parasite identification. The fish were divided into two length classes: smaller and larger than 50 cm. To assess the effects of parasites on fish condition, the Fulton coefficient, expressed with the formula: WF = G · L⁻³ x 100, was calculated. Results. The fish were found to be hosts to 17 parasite taxa. The Ciliophora were represented by Trichodinella epizootica (Raabe, 1950); the Myxozoa by Myxidium giardi Cépede, 1906; the Digenea by Bunodera luciopercae (Müller, 1784), Deropristis inflata (Molin, 1859), Diplostomum spp., and Ichthyocotylurus platycephalus (Creplin, 1852); the Cestoda by Bothriocephalus claviceps (Goeze, 1782), Proteocephalus macrocephalus (Creplin, 1815), and Proteocephalus sp.; the Nematoda by Anguillicola crassus Kuwahara, Niimi et Itagaki, 1974, Camallanus lacustris (Zoega, 1776), C. truncatus (Rudolphi, 1814), and Hysterothylacium aduncum (Rudolphi, 1802); the Acanthocephala by Acanthocephalus lucii (Müller, 1776) and Corynosoma strumosum (Rudolphi, 1802); the Hirudinea by Piscicola geometra (Linnaeus, 1761); and the Copepoda by Ergasilus sieboldi Nordmann, 1832. All fishes were infected, and the mean intensity of all parasites was 4.8 inds. The nematode Anguillicola crassus was the most frequent parasite (67.8%, 4.2 inds), represented by all developmental stages, but mostly by adult specimens. The fish condition coefficient was somewhat higher in the eel larger than 50 cm (0.1746) than in those smaller than 50 cm (0.1734); in addition, only Anguillicola crassus-free fish showed a higher condition coefficient (0.1861), compared to the infected specimens (0.1715).

    Introduction. Eel is one of the most valuable commercial fish species of the Vistula Lagoon. For this reason its infection by non-indigenous species of parasites is the subject of the interest of sciencists. Material and methods. A total of 90 eel specimens caught in the Polish part of the Vistula Lagoon were examined over the period of May-August 2005. The fish were subjected to standard procedures of parasitological examination and parasite identification. The fish were divided into two length classes: smaller and larger than 50 cm. To assess the effects of parasites on fish condition, the Fulton coefficient, expressed with the formula: WF = G · L⁻³ x 100, was calculated. Results. The fish were found to be hosts to 17 parasite taxa. The Ciliophora were represented by Trichodinella epizootica (Raabe, 1950); the Myxozoa by Myxidium giardi Cépede, 1906; the Digenea by Bunodera luciopercae (Müller, 1784), Deropristis inflata (Molin, 1859), Diplostomum spp., and Ichthyocotylurus platycephalus (Creplin, 1852); the Cestoda by Bothriocephalus claviceps (Goeze, 1782), Proteocephalus macrocephalus (Creplin, 1815), and Proteocephalus sp.; the Nematoda by Anguillicola crassus Kuwahara, Niimi et Itagaki, 1974, Camallanus lacustris (Zoega, 1776), C. truncatus (Rudolphi, 1814), and Hysterothylacium aduncum (Rudolphi, 1802); the Acanthocephala by Acanthocephalus lucii (Müller, 1776) and Corynosoma strumosum (Rudolphi, 1802); the Hirudinea by Piscicola geometra (Linnaeus, 1761); and the Copepoda by Ergasilus sieboldi Nordmann, 1832. All fishes were infected, and the mean intensity of all parasites was 4.8 inds. The nematode Anguillicola crassus was the most frequent parasite (67.8%, 4.2 inds), represented by all developmental stages, but mostly by adult specimens. The fish condition coefficient was somewhat higher in the eel larger than 50 cm (0.1746) than in those smaller than 50 cm (0.1734); in addition, only Anguillicola crassus-free fish showed a higher condition coefficient (0.1861), compared to the infected specimens (0.1715).

    Opis:
    Lactoferrin (LF) is a glycoprotein found in milk, neutrophil granules, secretions and selected organs of mammals. Lactoferrin exhibits antibacterial, antiviral, fungicidal, immunoregulatory and other functions. Although fish are devoid of this protein and its cell receptors, LF effect on the immune mechanisms of fish has been demonstrated. The objective of this study was to investigate the effect of bovine lactoferrin, applied in vitro, on the activity of head kidney and spleen leukocytes in three freshwater fish species: rainbow trout (Oncorhynchus mykiss), European eel (Anguilla anguilla) and weis catfish (Silurus glanis). The obtained results validate LF beneficial effect on the respiratory burst of phagocytes in rainbow trout and weis catfish despite the fact that the potential killing activity against Aeromonas hydrophila was not stimulated in any of the studied species. Bovine lactoferrin enhanced the proliferation of T-lymphocytes in rainbow trout and European eel, as well as of B-lymphocytes in rainbow trout.
