life cycle of hysterothylacium haze (nematoda: anisakidae: raphidascaridinae). | natural infections with hysterothylacium haze in the japanese common goby, acanthogobius flavimanus, were observed in detail. in gobies in which no worm eggs were deposited, second-stage larvae were found in the digestive tract wall, and third-stage larvae occurred in the digestive tract wall, mesentery, and body cavity, whereas fourth-stage larvae and adults were found in the body cavity. this stage-habitat relationship demonstrates the infectivity of second-stage larvae to the goby and the lar ... | 1989 | 2795378 |
the life cycle of pygidiopsis ardeae køie, 1990 (digenea, heterophyidae). | ocellate cercariae, consistent with the description of cercaria angularis honer, 1961, developing in rediae in hydrobia ulvae (pennant) and hydrobia ventrosa (montagu) (prosobranchia, hydrobiidae) from denmark, were shown to be larvae of pygidiopsis ardeae køie, 1990 (heterophyidae, pygidiopsinae). euryhaline fishes such as the sticklebacks gasterosteus aculeatus linnaeus and pungitius pungitius (linnaeus), and the common goby pomatoschistus microps (krøyer) are second intermediate hosts in dani ... | 1990 | 2380862 |
parasite communities of the salzhaff (northwest mecklenburg, baltic sea). i. structure and dynamics of communities of littoral fish, especially small-sized fish. | the parasites of ten fish species, including four gobiidae, three gasterosteidae, two syngnathidae, and one zoarcidae from the salzhaff region, northwest mecklenburg, baltic sea, were investigated in 1995 and 1996. as many as 36 parasite species, represented by diverse groups of helminths and protozoans as well as annelids and copepods, are found during 4 seasons in these hosts. by far the most abundant group is represented by digeneans, comprising 15 species, followed by 7 cestodans and 6 nemat ... | 1999 | 10227054 |
the influence of oxygen stress on female choice for male nest structure in the common goby. | this study examines the role of dissolved oxygen in modifying female mate choice in the common goby, pomatoschistus microps. experimental manipulations of nests showed that under normal (saturated) oxygen conditions, females preferred to spawn in nests with the most elaborate construction, that is, those with the most sand on top and the smallest entrance. such manipulated nests proved less vulnerable to detection by an egg predator, the shore crab, carcinus maenas, but these small entrances may ... | 1999 | 10053086 |
host death: a necessary condition for the transmission of aphalloides coelomicola dollfus, chabaud, and golvan, 1957 (digenea, cryptogonimidae)? | eggs of the trematode aphalloides coelomicola were observed free in the abdominal cavity of pomatoschistus microps from march 1993 to october 1995 (pisces, gobiidae) in the vaccares lagoon (delta du rhone, france). the eggs were contained in a fine membrane of parasitic origin as no immunological reaction of the fish was noted. the alternatively high prevalence of adults and low prevalence of free eggs, and vice versa, suggest that p. microps is both the second intermediate and final hosts of th ... | 2000 | 10780566 |
effects of the digenean parasites labratrema minimus and cryptocotyle concavum on the growth parameters of pomatoschistus microps and p. minutus from southwest wales. | during the present study, about 800 specimens of gobies (pomatoschistus microps and p. minutus) from two sites at gower peninsula, southwest wales, were studied. both species were infected with the digenean parasites labratrema minimus and cryptocotyle concavum. the effects of these parasites on host-growth parameters such as the condition factor, the gutted condition factor, the hepatosomatic index, and the gonadosomatic index were considered. the results of multiple regression and hierarchical ... | 2001 | 11355688 |
identification of a host-associated species complex using molecular and morphometric analyses, with the description of gyrodactylus rugiensoides n. sp. (gyrodactylidae, monogenea). | gyrodactylus rugiensis was originally described as a parasite occurring on the marine gobies pomatoschistus minutus and pomatoschistus microps. in our preliminary survey this species was also frequently found on pomatoschistus pictus and pomatoschistus lozanoi. subsequent molecular analysis of the internal transcribed spacers rdna region revealed that this parasite actually represents a complex of two apparently cryptic species, one restricted to p. microps and the other shared by p. minutus, p. ... | 2002 | 12062562 |
dynamics of kudoa camarguensis (myxosporean) infection in two gobiid species, pomatoschistus microps and p. minutus (teleostei: pisces), in the rhĵne river delta, france. | the occurrence of the myxosporean parasite kudoa camarguensis was surveyed monthly during 1997 in a brackish-water lagoon of the rhĵne river delta (france). k. camarguensis was found on its typical host, pomatoschistus microps, and on an additional host, p. minutus. prevalence and mean abundance were higher in the typical host than in the additional host due to differences in the temporal occupancy of the lagoon by the 2 species. the temporal occurrence of this myxosporean parasite is discussed ... | 2002 | 12078985 |
parasite populations and communities from the shallow littoral of the orther bight (fehmarn, sw baltic sea). | parasites of host guilds, such as mud snails (five species), benthic crustaceans (six species) and small-sized fishes ( pomatoschistus microps, gasterosteus aculeatus, pungitius pungitius, young pleuronectes flesus), were investigated in the other bight off west fehmarn (kiel bight, german baltic sea). the hosts, especially the herbivorous hydrobia spp, gammarus spp and idothea chelipes, attained extremely high densities in three habitats ( enteromorpha belt, fucus belt, sandy bottom), which may ... | 2002 | 12122431 |
gyrodactylus quadratidigitus n. sp. (monogenea: gyrodactylidae), a parasite of the leopard-spotted goby thorogobius ephippiatus (lowe) from the south-western coast of the uk. | gyrodactylus quadratidigitus n. sp. (monogenea, gyrodactylidae) is described from the gills, fins and skin of thorogobius ephippiatus (lowe) (leopard-spotted goby) from portland castle bay, dorset, uk. g. quadratidigitus n. sp. most closely resembles the species of gyrodactylus previously described by geets from pomatoschistus microps (krøyer) in the approximate shape and size of the attachment hooks but can be readily distinguished from other species of the genus by the distinctive square shape ... | 2003 | 12815225 |
ellipsomyxa gobii gen. et sp. n. (myxozoa: ceratomyxidae) in the common goby pomatoschistus microps (teleostei: gobiidae) from denmark. | a new myxosporean species ellipsomyxa gobii gen. et sp. n. is described from the common goby pomatoschistus microps (krøyer) (perciformes, gobiidae). plasmodia with long branched pseudopodia in the gallbladder develop to subspherical bisporous plasmodia. the myxospores were found in the gallbladder, and the hepatic and bile ducts. the new genus is characterised by the morphology of the myxospores. the myxospores have smooth thin valves elongated in the direction perpendicular to the plane of the ... | 2003 | 14971595 |
four-year monitoring of parasite communities in gobiid fishes of the south-western baltic. i. guild and component community. | the parasite communities of goby species (teleostei, percomorphi) from the south-western baltic sea were investigated from 1997 to 2000 in three different seasons. in total, 30 parasite species were found in the guild of four goby spp. from dahmeshöved (lübeck bight). the component community of pomatoschistus minutus comprised 22, pomatoschistus pictus 20, gobiusculus flavescens 18 and gobius niger 14 parasite species, whereas pomatoschistus microps from the salzhaff (mecklenburg bight) harboure ... | 2003 | 12827504 |
development of enzyme-linked immunosorbent assays for two forms of vitellogenin in japanese common goby (acanthogobius flavimanus). | two vitellogenins (vgs) were detected in serum from estradiol-17beta (e(2))-injected japanese common goby (acanthogobius flavimanus). vitellogenins with molecular masses of 530 kda (vg-530) and 320 kda (vg-320) were purified, and used to raise specific antisera in rabbits. sandwich enzyme-linked immunosorbent assays (elisas) for vg-530 and vg-320 were developed using the antisera and the isolated vgs. the sensitivity ranges of these elisas were 1.25-160 ng/ml for vg-530 and 0.26-66 ng/ml for vg- ... | 2003 | 12714018 |
effects of endocrine-disrupting chemicals on expression of ubiquitin c-terminal hydrolase mrna in testis and brain of the japanese common goby. | we investigated the effects of endocrine-disrupting chemicals (edcs) on the expression of ubiquitin c-terminal hydrolase (uch) mrna in the testis and brain of the japanese common goby, acanthogobius flavimanus. the cdna sequence of goby uch contained an open reading frame encoding 220 amino acid residues (m(r)=24,223) with 51.3% overall sequence identity with human and mouse uchl1. a competitive pcr assay was used to quantify the levels of uch mrna in the testis and brain of male gobies after ex ... | 2004 | 15522430 |
deduced primary structure of two forms of vitellogenin in japanese common goby (acanthogobius flavimanus). | complete nucleotide sequences of two forms of vitellogenin (vg) cdna in japanese common goby were determined from a liver cdna library of e(2)-treated male fish. these two vg cdnas contained complete open reading frames encoding 1664 and 1238 amino acid residues including signal peptides, respectively. from comparison of the deduced amino acid sequences of both vgs and the partial amino acid sequences of the yolk proteins, the longer sequence was concluded to be cdna of the vg-530 and the shorte ... | 2004 | 15094332 |
molecular and morphological comparisons between gyrodactylus ostendicus n. sp. (monogenea: gyrodactylidae) on pomatoschistus microps (krøyer) and g. harengi malmberg, 1957 on clupea harengus membras l. | gyrodactylus ostendicus n. sp. was exclusively found on fins of the common goby pomatoschistus microps (krøyer). the haptoral hard parts are among the smallest described for species of gyrodactylus. a presumed similarity between the new species and g. harengi malmberg, 1957 (subgenus metanephrotus malmberg, 1964) encouraged a comparative approach. a morphological analysis showed the marginal hook sickles of g. ostendicus to be of quite a different type and similar to those of g. arcuatus bychows ... | 2004 | 15449826 |
ellipsomyxa gobii (myxozoa: ceratomyxidae) in the common goby pomatoschistus microps (teleostei: gobiidae) uses nereis spp. (annelida: polychaeta) as invertebrate hosts. | nereis diversicolor o.f. müller and n. succinea frey et leuckart (polychaeta, nereidae) living in brackish shallow areas in denmark are naturally infected with tetractinomyxon actinospores. infected nereis spp. were experimentally fed to various potential fish hosts, and the actinosporean stages developed into myxosporean stages of ellipsomyxa gobii køie, 2003 (ceratomyxidae) in the gallbladder of the common goby pomatoschistus microps (krøyer) (gobiidae). the european eel anguilla anguilla (l.) ... | 2004 | 15139372 |
four-year monitoring of parasite communities in gobiid fishes of the southwest baltic: iii. parasite species diversity and applicability of monitoring. | the parasite infrapopulations of five goby species (pomatoschistus minutus, p. pictus, p.microps, gobiusculus flavescens and gobius niger) were investigated during spring, summer and autumn of the years 1997-2000. in total, 34 parasite species were found: 17 digenea, 6 nematoda, 5 cestoda, 3 acanthocephala, 2 protozoa, and 1 monogenea. the dominant parasites were the digeneans podocotyle atomon and cryptocotyle concavum, which represent different ecological groups in terms of their modes of tran ... | 2005 | 15609062 |
comparative studies on goby (teleostei) parasite communities from the north and baltic sea. | the parasite communities of three goby species from the marine north and the brackish baltic sea were compared. the samples of summer 1992/93 from helgoland, lubeck and kiel bight comprised a parasite spectrum of 4-5 in pomatoschistus microps, 2-3 in p. pictus or 3-8 parasite species in gobiusculus flavescens. the highest numbers were found in kiel bight whereas those of helgoland and lubeck bight differed between 3 and 7, respectively. in comparing the species identity of the studied localities ... | 2005 | 15772865 |
molecular cloning of two estrogen receptors expressed in the testis of the japanese common goby, acanthogobius flavimanus. | we isolated cdna clones of two estrogen receptors (er1 and er2) from testis of the japanese common goby (acanthogobius flavimanus). the cdnas of er1 contained 3,796 nucleotides, including an open reading frame encoding 564 amino acids (mr: 61.9 kda); the cdna for er2 was 3,274 nucleotides long, with an open reading frame of 567 amino acids (mr: 63.5 kda). the deduced aminoacid sequences of er1 and er2 each had a characteristic er structure consisting of five domains (a/b, dna-binding, d, ligand- ... | 2007 | 18088175 |
acute effects of copper and mercury on the estuarine fish pomatoschistus microps: linking biomarkers to behaviour. | the main objective of the present study was to investigate possible links between biomarkers and swimming performance in the estuarine fish pomatoschistus microps acutely exposed to metals (copper and mercury). in independent bioassays, p. microps juveniles were individually exposed for 96 h to sub-lethal concentrations of copper or mercury. at the end of the assays, swimming performance of fish was measured using a device specially developed for epibenthic fish (spede). furthermore, the followi ... | 2009 | 19628251 |
myxobolus albi n. sp. (myxozoa) from the gills of the common goby pomatoschistus microps krøyer (teleostei: gobiidae). | a recent investigation into the myxozoan fauna of common gobies, pomatoschistus microps, from the forth estuary in scotland, revealed numerous myxosporean cysts within the gill cartilage. they were composed of polysporous plasmodia containing myxobolid spores that were morphologically different from the other known species of myxobolus and from the myxosporeans previously recorded from this host (i.e. the ceratomyxid ellipsomyxa gobii, infecting the gall bladder, and the kudoid kudoa camarguensi ... | 2009 | 19737194 |
high site fidelity and low site connectivity in temperate salt marsh fish populations: a stable isotope approach. | adult and juvenile fish utilise salt marshes for food and shelter at high tide, moving into adjacent sublittoral regions during low tide. understanding whether there are high levels of site fidelity for different species of coastal fish has important implications for habitat conservation and the design of marine protected areas. we hypothesised that common salt marsh fish species would demonstrate a high site fidelity, resulting in minimal inter-marsh connectivity. carbon ((13)c) and nitrogen (( ... | 2011 | 21786154 |
multi-biomarker responses to estuarine habitat contamination in three fish species: dicentrarchus labrax, solea senegalensis and pomatoschistus microps. | several biomarker responses were determined in three fish species, dicentrarchus labrax, solea senegalensis and pomatoschistus microps, from two estuaries of the portuguese coast, ria de aveiro and tejo. both estuaries have significant anthropogenic influences from multiple sources (industrial, agricultural and shipping activities), which was evident from sediment chemical characterization concerning metal (copper, zinc, nickel, lead and chromium) and polycyclic aromatic hydrocarbon (pah) concen ... | 2011 | 21356184 |
Short-term variability of multiple biomarker response in fish from estuaries: Influence of environmental dynamics. | Short-term variability in biomarker responses and the effects of temperature and salinity variation were explored in three fish species (Dicentrarchus labrax, Solea senegalensis and Pomatoschistus microps) occurring in the Tejo estuary. Short-term variability in biomarkers was observed in all species although no pattern was discerned over time (days to weeks). Antioxidant enzymes activity (superoxide dismutase (SOD) and catalase (CAT)) showed low temporal variability, indicating some constancy o ... | 2011 | 21868087 |
assessing food web dynamics and relative importance of organic matter sources for fish species in two portuguese estuaries: a stable isotope approach. | stable carbon and nitrogen isotopes (δ¹³c, δ¹⁵n) were used to analyse food web dynamics of two of the main estuaries of the portuguese coast: tejo and mira. the ultimate sources of organic matter supporting production of some of the most abundant and commercially important fish species were determined; and seasonal, inter- and intra- estuarine differences in the trophic relations among producers and consumers were identified. stable isotope analysis was performed in different producers, primary ... | 2011 | 21958908 |
tributyltin in blood of marine fish collected from a coastal area of northern kyushu, japan. | we investigated levels of the pollutant tributyltin (tbt) in blood of pufferfishes (six species), japanese sea perch, red sea bream, japanese common goby, japanese flounder, rockfish, conger eel, and sea mullet collected off the coast of northern kyushu, japan. we found considerable levels of tbt (1.4-190 ng/ml) accumulated in the blood of these fish. blood tbt concentrations were 1.3-22.5 times liver concentrations and 4.9-78 times muscle concentrations, except in conger eel and mullet. we dete ... | 2011 | 21945558 |
