| myxozoa of deep-sea fishes in the northwestern atlantic. | the gall bladder of 5 species of deep-water fishes (coryphaenoides armatus, coryphaenoides rupestris, macrourus berglax, antimora rostrata, and synaphobranchus kaupi) from the new york bight and carson canyon areas in the northwest atlantic were examined for myxozoan parasites. myxidium coryphaenoidium was found in 4 fish species, whereas auerbachia pulchra and ceratomyxa sp. were each observed in 1 fish species. prevalence of myxozoan infections was greater in fishes taken off the new york bigh ... | 1990 | 2319435 |
| proximate composition, fatty acid and lipid class composition of the muscle from deep-sea teleosts and elasmobranchs. | proximate composition of muscle was determined for the following deep-sea fish species: roughhead grenadier (macrourus berglax), mora/deep-sea cod (mora moro), portuguese dogfish (centroscymnus coelolepis), black dogfish (centroscyllium fabricii), leafscale gulper shark (centrophorus squamosus), greater lantern shark (etmopterus princeps), smalleyed rabbitfish/ghostshark (hydrolagus affinis), birdbeak dogfish (deania calcea) and two species of smooth head (alepocephalus bairdii and alepocephalus ... | 2005 | 15694592 |
| pressure effects on the gtpase activity of brain membrane g proteins of deep-living marine fishes. | in marine fishes, heterotrimeric guanyl nucleotide binding proteins (g proteins), which couple cell surface membrane receptors to their effector elements, are sensitive to hydrostatic pressure. the intrinsic high affinity gtpase activity of the alpha subunits of g proteins in three signaling systems coupled to adenylyl cyclase, the a(1) adenosine receptor, the muscarinic cholinergic receptor and the beta-adrenergic receptor, was tested at pressures up to 340 atm. brain membrane preparations from ... | 2003 | 12892762 |
| isolation and characterization of microsatellite loci in the deep-sea marine fish, the roundnose grenadier (coryphaenoides rupestris). | we developed polymerase chain reaction primers for eight dinucleotide microsatellite loci in the marine deep sea fish, roundnose grenadier (coryphaenoides rupestris). all markers were obtained from a partial genomic dna library, and characterized in 90 unrelated individuals from one putative population sampled on the mid-atlantic ridge. the number of alleles ranged from two to 61 with an average of 21 per locus. the observed heterozygosity levels ranged from 0.301 to 0.987 with an average of 0.6 ... | 2008 | 21585951 |
| further observations on cryptobia dahli (mastigophorea: kinetoplastida) parasitizing marine fish. | studies were conducted primarily to ascertain the mode of transmission of cryptobia dahli parasitizing the digestive tract of lumpfish (cyclopterus lumpus). another flagellate, morphologically similar to c. dahli, was also observed in the gut of a deepsea fish (macrourus berglax). several invertebrates, which are food for lumpfish, were examined for flagellates, but were neither infected nor showed evidence of cystic stages. parasites were more abundant in the stomach, especially at about ph 5, ... | 2009 | 1787422 |
| neoascarophis macrouri n. sp. (nematoda: cystidicolidae) from the stomach of macrourus berglax (macrouridae) in the eastern greenland sea. | a new species of parasitic nematode, neoascarophis macrouri n. sp. (cystidicolidae), is described from the stomach and stomach wall of the marine deep-water fish macrourus berglax (onion-eye grenadier) in the eastern greenland sea (north atlantic ocean). the new species, studied using both light and scanning electron microscopy, is characterised mainly by the location of the vulva near the posterior end of the body (a short distance anterior to the anus), non-filamented eggs, the structure of th ... | 2006 | 16612659 |
