Characterization of Leuconostoc strains isolated from fresh anchovy (Engraulis anchoita).
The biomass value of anchovy (Engraulis anchoita), the most abundant fi sh species in the Southwest Atlantic Ocean, is considered to be around 4,300,000 tons, with a maximum sustainable yield of 1,140,000 tons (Cabrer et al., 2002), being at present under exploited at 27,800 tons/year (SAGPyA, 2008). Recently, as part of the FAO’s project Towards a Sustainable Aquaculture: Selected Issues and G...
متن کاملDigenetic trematodes parasitic on Engraulis anchoita (Pisces: Engraulidae) from Argentina and Uruguay.
A total of 2,086 specimens of Engraulis anchoita Hubbs et Marini (Pisces: Engraulidae), from waters off Argentina and Uruguay were examined for parasitic digeneans. Four species of digeneans were found, Parahemiurus merus (Linton, 1910) (adult) in the stomach; Lecithochirium microstomum Chandler, 1935 (non-ovigerous and ovigerous juveniles) in the swimbladder; Cardiocephaloides sp. (metacercari...
متن کاملStructure and spectral sensitivity of photoreceptors of two anchovy species: Engraulis japonicus and Engraulis encrasicolus
The morphology, fine structure and spectral sensitivity of retinal photoreceptors of two anchovy species were investigated using light and electron microscopy and microspectrophotometry. Distinct regional specialisation of cones was observed. Long and short (bilobed) cones were observed in the horizontal retinal belt, including the nasal and temporal retinal zones. Only triple cones with two lo...
متن کاملUse of multivariate analysis to assess the nutritional condition of fish larvae from nucleic acids and protein content.
The nutritional condition of turbot larvae (Scophthalmus maximus) was assessed by a multivariate analysis with DNA, RNA, and protein content as input variables. Special attention was given to the time that feeding began and to the timing and duration of starvation. The combination of the principal components analysis and the stepwise discriminant analysis, both techniques of multivariate analys...
متن کاملPolymorphic microsatellite loci for the Japanese anchovy Engraulis japonicus (Engraulidae).
We isolated and characterized 14 polymorphic microsatellite loci in the Japanese anchovy (Engraulis japonicus) using a (GT)(13)-enriched genomic library. The numbers of alleles per locus ranged from 6 to 31, with a mean of 17.8. The observed and expected heterozygosities ranged from 0.180 to 0.949 and from 0.172 to 0.966, with means of 0.731 and 0.825, respectively. All 14 loci were in Hardy-We...
