| molecular identification and larval morphological description of contracaecum pelagicum (nematoda: anisakidae) from the anchovy engraulis anchoita (engraulidae) and fish-eating birds from the argentine north patagonian sea. | anisakids use invertebrates as paratenic and/or intermediate hosts as a basic feature of larval transmission. the third-stage larva usually develops in invertebrates which are prey items of finfish paratenic hosts. contracaecum larvae molt twice inside the egg and hatch as free third-stage larvae ensheathed in the second-stage larval cuticle. copepods act as paratenic or obligatory hosts, usually ingesting these free l3 larvae, and fish act as intermediate/paratenic or metaparatenic hosts preyin ... | 2013 | 23500719 |
| identification, technological and safety characterization of lactobacillus sakei and lactobacillus curvatus isolated from argentinean anchovies (engraulis anchoita). | in this study, the identification and characterization of lactobacillus previously isolated from fresh anchovies (engraulis anchoita) are investigated. 16s rdna partial sequencing assigned all the isolates to belong to the lactobacillus sakei/curvatus group. fourteen out of 15 isolates were identified as l. sakei by phenotypic traits: they exhibited catalase activity and fermented melibiose, although only 10 of them hydrolyzed arginine. these results were confirmed by multiplex pcr-based restric ... | 2013 | 23807916 |
| blood-specific isotopic discrimination factors in the magellanic penguin (spheniscus magellanicus). | the use of stable isotopes for ecological studies has increased exponentially in recent years. isotopic trophic studies are based on the assumption that animals are what they eat plus a discrimination factor. the discrimination factor is affected by many variables and can be determined empirically. the magellanic penguin is a highly abundant marine bird that plays a key role in the southern oceans. this study provides the first estimation of the magellanic penguin blood discrimination factor for ... | 2016 | 27476661 |
| assessment of the labelling accuracy of spanish semipreserved anchovies products by fins (forensically informative nucleotide sequencing). | anchovies have been traditionally captured and processed for human consumption for millennia. in the case of spain, ripened and salted anchovies are a delicacy, which, in some cases, can reach high commercial values. although there have been a number of studies presenting dna methodologies for the identification of anchovies, this is one of the first studies investigating the level of mislabelling in this kind of products in europe. sixty-three commercial semipreserved anchovy products were coll ... | 2016 | 27441295 |
| effect of different preservation processes on chemical composition and fatty acid profile of anchovy (engraulis anchoita). | the effects of salting-ripening, canning and marinating processes on chemical composition and fatty acid profile of anchovy (engraulis anchoita) were evaluated (p = 0.01), with emphasis on long-chain polyunsaturated fatty acids. fresh anchovy showed a high proportion of pufas (∼45 g/100 g total lipid) with an eicosapentaenoic (epa) + docosahexaenoic (dha) content of 27.08 g/100 g total lipid. the salting-ripening process led to the largest changes in the chemical composition and the fatty acid p ... | 2015 | 26576657 |

| large-scale ichthyoplankton and water mass distribution along the south brazil shelf. | ichthyoplankton is an essential component of pelagic ecosystems, and environmental factors play an important role in determining its distribution. we have investigated simultaneous latitudinal and cross-shelf gradients in ichthyoplankton abundance to test the hypothesis that the large-scale distribution of fish larvae in the south brazil shelf is associated with water mass composition. vertical plankton tows were collected between 21°27' and 34°51's at 107 stations, in austral late spring and ea ... | 2014 | 24614798 |
| feasibility of microwave-induced combustion for trace element determination in engraulis anchoita by icp-ms. | a method based on microwave-induced combustion (mic) was developed for fish (engraulis anchoita) digestion and subsequent determination of as, cd, co, cr, cu, fe, mn, mo, ni, se, and zn by inductively coupled plasma mass spectrometry (icp-ms). a reflux step (5 min) was applied to improve absorption and recovery of analytes. nitric acid was investigated as absorbing solution and suitable results were achieved using 5 mol l⁻¹ hno₃. microwave-assisted digestion in closed vessels using concentrated ... | 2014 | 24128565 |
| development of quality index method for anchovy (engraulis anchoita) stored in ice: assessment of its shelf-life by chemical and sensory methods. | the objective of this study was to develop a quality index method for engraulis anchoita stored in ice and to determine its shelf-life based on this quality index method and chemical indices such as total volatile bases and thiobarbituric acid-reactive substances. besides, the chemical composition with emphasis on the polyunsaturated fatty acids content was determined. the results indicate that e. anchoita is a valuable protein source and lipid with important content of n-3 polyunsaturated fatty ... | 2012 | 22859648 |
| ripening of salted anchovy (engraulis anchoita): development of lipid oxidation, colour and other sensorial characteristics. | changes in lipids are in general associated with quality deterioration, though earlier studies in anchovy indicate that the volatile compounds of importance to the characteristic flavour could be generated by lipid oxidation. the aim of the present paper was to study the changes in the fatty acid composition and the lipid oxidation of engraulis anchoita during ripening and their relationship with the development of the typical sensorial characteristics. | 2011 | 21302314 |
| host ontogeny and the temporal decay of similarity in parasite communities of marine fish. | geographical distances between host populations are key determinants of how many parasite species they share. in principle, decay in similarity should also occur with increasing distance along any other dimension that characterizes some form of separation between communities. here, we apply the biogeographical concept of distance decay in similarity to ontogenetic changes in the metazoan parasite communities of three species of marine fish from the atlantic coast of south america. using differen ... | 2010 | 20188105 |
| parasites as biological tags for stock discrimination in marine fish from south american atlantic waters. | the use of parasites as biological tags in population studies of marine fish in the south-western atlantic has proved to be a successful tool for discriminating stocks for all species to which it has been applied, namely: scomber japonicus, engraulis anchoita, merluccius hubbsi and cynoscion guatucupa, the latter studied on a broader geographic scale, including samples from uruguayan and brazilian waters. the distribution patterns of marine parasites are determined mainly by temperature-salinity ... | 2007 | 17578590 |
| morphological and histochemical characterization of the mucosa of the digestive tract in engraulis anchoita. | the histomorphological aspects as well as the histochemical content and distribution of glycoproteins (gps) in the mucosa of the digestive tract of the anchovy engraulis anchoita were studied. the buccopharyngeal cavity is lined by a squamous stratified epithelium with mucous superficial cells; the oesophagus shows two zones, cranial with a squamous stratified epithelium with mucous superficial cells and caudal with a columnar secretory epithelium. finally, the stomach presents both the cranial ... | 2003 | 14651481 |
| characterization of the swimming muscle of the anchovy engraulis anchoita (hubbs and martini 1935). | the lateral muscle characteristics of individual female anchovies (engraulis anchoita) were studied by histochemical and ultrastructural techniques. red, pink and white fibres were discerned on the basis of the activity of the metabolic enzymes succinic dehydrogenase, phosphorylase and myofibrilar atpase, and the usage of sudan and periodic-acid schiff staining techniques. red fibres were located at the surface, white fibres deep inside and pink fibres in between. the red fibres appeared flatten ... | 2000 | 11008365 |
| mazocraeid monogeneans parasitic on engraulid fishes in the southwest atlantic. | two species of mazocraeid monogeneans are reported for the first time from argentinean-uruguayan engraulid fish hosts, engraulis anchoita and anchoa marini. mazocraes australis n. sp. collected from the gills of e. anchoita is described: this new species can be distinguished from the other congenerics by the number of genital hooks in the copulatory organ, the relative size of clamps, and the number of hooks in the terminal lappet. pseudanthocotyloides heterocotyle found in the gills of e. ancho ... | 1999 | 10207359 |
