| [anisakiasis in the nantes area. from fishmongers' stalls to medical offices]. | 1,103 fish-fillets belonging to 4 species were examined during one year, during a survey conducted among commercial marine fish-fillets in the nantes area (west coast) in france. anisakis simplex l3 were found in 3 different species and most of them are frequently present in coal fish (pollachius virens) and whiting (merlangius merlangus). we report 6 cases of human anisakiasis (3 certain cases and 3 probably cases). diagnosis was established in 3 cases by microscopic analysis of intestin bowel ... | 1995 | 8745739 |
| kinetics of interactions of lactic acid, ph and atmosphere on the growth and survival of yersinia enterocolitica ip 383 o:9 at 4 degrees c. | the influence of different lactic acid concentrations (0.1, 0.3, 0.5, 0.7, 0.9, 1.1% v/v), within ph range of 3.9 to 5.8 on the aerobic and anaerobic growth and survival kinetics of the virulent strain of y. enterocolitica ip 383 o:9, was determined in tryptone soy broth at 4 degrees c. growth and survival data were analyzed and fitted by a modification of the whiting and cygnarowicz-provost model, using the minpack software library. initial generation times, initial specific growth rates, lag t ... | 1995 | 8579992 |
| red-edge-excitation fluorescence spectroscopy of single-tryptophan proteins. | with the aim of finding non-equilibrium dipole-relaxational electronic excited states of tryptophan residues in proteins the dependence of the fluorescence emission maximum on excitation wavelength was studied for several proteins containing a single tryptophan residue per molecule. spectral shifts upon red-edge excitation are not observed for short wavelength-emitting proteins (azurin, two-calcium form of whiting parvalbumin, ribonucleases c2 and t1). this may be because of the non-polar enviro ... | 1988 | 3208709 |
| the effects of ciguatoxin on the nerves of the teleost fish, sillago ciliata. | the absolute refractory period, relative refractory period, and the duration and magnitude of the supernormal period were measured after incubation of fish nerves with ciguatoxin and other channel modifying compounds, tetrodotoxin, veratridine, verapamil, and lignocaine. in vitro electrophysiological studies were carried out on the lateral line nerve of the whiting, sillago ciliata cuvier. electrophysiological changes in fish nerves after exposure to ciguatoxin (0.3 mu.ml-1) and veratridine (1 x ... | 1992 | 1344907 |
| role of kairomones in host location of the pennellid copepod parasite, lernaeocera branchialis (l. 1767). | the life cycle of the parasitic copepod lernaeocera branchialis involves 2 hosts, typically a pleuronectiform host upon which development of larvae and mating of adults occurs and a subsequent gadoid host, upon which the adult female feeds and reproduces. both the copepodid and adult female stages must therefore locate and identify a suitable host to continue the life cycle. several mechanisms are potentially involved in locating a host and ensuring its suitability for infection. these may inclu ... | 2013 | 23369461 |
| fish mortality by impingement on the cooling-water intake screens of britain's largest direct-cooled power station. | an estimated 5.66 x 10(7) fish (summed quarterly 95% confidence intervals: 3.01 x 10(7)-1.07 x 10(8)) weighing 258.4 t (143.2-467.9 t) were killed on the cooling-water intake screens of the 2400 mw longannet power station (forth estuary) in january 1999--december 2000. abundance and number of species (40) collected were close to predictions for a power station of this size and latitude. potential losses of equivalent adult whiting (merlangius merlangus), cod (gadus morhua), and plaice (pleuronec ... | 2008 | 18243248 |
| the complete mitochondrial genome of the whiting, merlangius merlangus and the haddock, melanogrammus aeglefinus: a detailed genomic comparison among closely related species of the gadidae family. | we determined the first complete mitochondrial dna (mtdna) sequences for the whiting (merlangius merlangus, family gadidae, order gadiformes) and the haddock (melanogrammus aeglefinus, family gadidae, order gadiformes). the entire mitogenomes were amplified and sequenced by primer walking using newly designed specific internal primers. lengths were 16,569 and 16,585 bases for whiting and haddock respectively, lengths which lie within the range of previously reported gadiform sequences from atlan ... | 2006 | 16996701 |
| diclidophora merlangi (monogenea: diclidophoridae) on atlantic cod, gadus morhua. | diclidophora merlangi (kuhn, in nordmann, 1832), as species specific to whiting, merlangius merlangus (linnaeus, 1758), is reported and described for the first time on the gills of atlantic cod gadus morhua (linnaeus, 1758). of the about 1,200 cod examined in this article, only 2 specimens of d. merlangi occurred on 2 fish, suggesting that they represented accidental infections. the 2 specimens showed specific traits of d. merlangi, but their size was considerably smaller than that of d. merlang ... | 2006 | 16995384 |
| taqman dna technology confirms likely overestimation of cod (gadus morhua l.) egg abundance in the irish sea: implications for the assessment of the cod stock and mapping of spawning areas using egg-based methods. | recent substantial declines in northeastern atlantic cod stocks necessitate improved biological knowledge and the development of techniques to complement standard stock assessment methods (which largely depend on accurate commercial catch data). in 2003, an ichthyoplankton survey was undertaken in the irish sea and subsamples of 'cod-like' eggs were analysed using a taqman multiplex, pcr (polymerase chain reaction) assay (with specific probes for cod, haddock and whiting). the taqman method was ... | 2005 | 15723679 |
| changes in fisheries discard rates and seabird communities. | it is clear that discards from commercial fisheries are a key food resource for many seabird species around the world. but predicting the response of seabird communities to changes in discard rates is problematic and requires historical data to elucidate the confounding effects of other, more 'natural' ecological processes. in the north sea, declining stocks, changes in technical measures, changes in population structure and the establishment of a recovery programme for cod (gadus morhua) will a ... | 2004 | 14973483 |
| 470 million years of conservation of microsatellite loci among fish species. | primers for 18 microsatellite loci originally isolated from whiting (merlangius merlangus, n = 6), stickleback (gasterosteus aculeatus, n = 5) and cod (gadus morhua, n = 7) were tested across a panel of diverse fish species, representing the three principal superclasses and most principal superorders of fish, to examine conservation of microsatellite regions across distantly related taxa. three methods were used. first, amplified fragments were analysed by southern blotting using the relevant mi ... | 1996 | 8677258 |

| revision of the oriental subfamily heteropteryginae kirby, 1896, with a re-arrangement of the family heteropterygidae and the descriptions of five new species of haaniella kirby, 1904. (phasmatodea: areolatae: heteropterygidae). | the areolate oriental family heteropterygidae kirby, 1893 is critically reviewed and the results of the present study contradict the arrangement suggested by zompro (2004), but in most aspects agree with a molecular study presented by whiting et al (2003) and a phylogenetic study presented by bradler (2009). the family is critically discussed and new hypotheses are presented for the phylogeny and intra-familiar relationships, placing the subfamily dataminae rehn & rehn, 1939 as the basalmost cla ... | 2016 | 27615907 |
| salmon blood plasma: effective inhibitor of protease-laden pacific whiting surimi and salmon mince. | the effect of salmon plasma (sp) from chinook salmon on proteolytic inhibition was investigated. sp was found to inhibit both cysteine and serine proteases as well as protease extracted from pacific whiting muscle. sp was found to contain a 55kda cysteine protease inhibitor through sds-page inhibitor staining. freeze dried salmon plasma (fsp) and salmon plasma concentrated by ultrafiltration (csp) were tested for their ability to inhibit autolysis in pacific whiting surimi and salmon mince at co ... | 2015 | 25624255 |
| community structure of soft sediment pool fishes in moreton bay, australia. | a survey of soft sediment tide pools was conducted to assess the occupation and assemblage of fishes on three different intertidal shores in moreton bay, australia, between january and december 2009. tide-pool volume ranged from 0· 30 to 29· 75 l and varied significantly between months and sites. a total of 1364 individuals representing 15 species and nine families of fishes were observed. at dunwich, fish assemblages were dominated by the sand goby favonigobius lentiginosus (89%) and whiting, s ... | 2011 | 21284630 |
| a new nematode, dichelyne alatae sp. n. (cucullanidae), from sillaginopsis panijus (pisces) of west bengal, india. | a new nemarode, dichelyne alatae sp. n., is described on the basis of the worms recovered from the intestine of the whiting, sillaginopsis panijus (perciformes: sillaginidae) from the estuary of the river hooghly at kalyani, west bengal, india. dichelyne alatae differs from congeners in having a small body size, deirids posterior to the oesophagus, short and wide caudal alae at the level of cloacal opening, unequal, alate spicules, a shield-shaped gubernaculum, a different number of caudal papil ... | 1995 | 8774775 |
| diet and feeding niches of juvenile gadus morhua, melanogrammus aeglefinus and merlangius merlangus during the settlement transition in the northern north sea. | a study on the feeding ecology of juvenile cod gadus morhua, haddock melanogrammus aeglefinus and whiting merlangius merlangus during the pelagic to demersal transition was carried out on fishes sampled throughout their settlement season at a local nursery ground in the north-western north sea, off the scottish east coast. a comprehensive quantitative taxonomic analysis of the diets, as described in the paper, showed the emergence of distinctive feeding niches, minimizing the potential for compe ... | 2011 | 21722113 |
| effectiveness of taqman probes for detection of fish eggs and larvae in the stomach contents of a teleost predator. | experiments were conducted on the ability of taqman molecular probes to detect plaice pleuronectes platessa dna from eggs, and cod gadus morhua dna from eggs and larvae following ingestion by a teleost predator, whiting merlangius merlangus. estimated half-life detection rate (t50) for eggs was 31 h, and 26 h for larvae, with some positive detections occurring even after visual inspection indicated complete gut clearance. because taqman probes are taxon specific, the results presented demonstrat ... | 2012 | 22747822 |
| a statistical model for estimation of fish density including correlation in size, space, time and between species from research survey data. | trawl survey data with high spatial and seasonal coverage were analysed using a variant of the log gaussian cox process (lgcp) statistical model to estimate unbiased relative fish densities. the model estimates correlations between observations according to time, space, and fish size and includes zero observations and over-dispersion. the model utilises the fact the correlation between numbers of fish caught increases when the distance in space and time between the fish decreases, and the correl ... | 2014 | 24911631 |
| sexual size dimorphism in three north sea gadoids. | existing biological data on whiting merlangius merlangus, cod gadus morhua and haddock melanogrammus aeglefinus from a long-term international survey were analysed to address sexual size dimorphism (ssd) and its effect on their ecology and management. results show that ssd, with larger females of the same age as males, is a result of higher growth rates in females. a direct consequence of ssd is the pronounced length-dependent female ratio that was found in all three gadoids in the north sea. fe ... | 2015 | 25457726 |
| response of branchial na(+)/k(+) atpase to changes in ambient temperature in atlantic cod (gadus morhua) and whiting (merlangius merlangus). | the maintenance of ion and ph homeostasis despite changes in ambient temperature is crucial for ectothermic organisms. thermal sensitivity of na(+)/k(+) atpase mrna expression, protein expression and activity was determined in gills of north sea cod (nc) and northeastern arctic cod (neac), acclimated for 6 weeks at 4 and 10 °c and compared to field samples of north sea cod (snc), acclimatized to early spring (4 °c) and summer (18 °c) conditions. the same analyses were conducted in gills of the c ... | 2016 | 26922791 |
