species specific taqman probes for simultaneous identification of gadus morhua l haddock melanogrammus aeglefinus l and whiting merlangius merlangus l
Molecular Ecology Notes, 2002Co-Authors: Martin I Taylor, I Rico, Ciro RicoAbstract:We report the development of a multiplex, single tube (TaqMan) PCR assay for the identification of three commercially important Gadoid species, the cod (Gadus morhua L.), the haddock (Melanogrammus aeglefinus L.) and the whiting (Merlangius merlangus L.). The assay unambiguously identifies known adult tissue samples, and ethanol-preserved eggs from all three species with greater than 98% accuracy, providing a powerful tool for the development of catch independent stock assessment methods, mapping of spawning sites and the detection of commercial fraud in the fishing and food production industries.

diet overlap and prey selection through metamorphosis in irish sea cod gadus morhua haddock melanogrammus aeglefinus and whiting merlangius merlangus
Canadian Journal of Fisheries and Aquatic Sciences, 2008Co-Authors: William Ll Rowlandsw Ll Rowlands, Mark Dickeycollas, Audrey J Geffen, Richard D M NashAbstract:Copepods in the genus Calanus are usually considered to be the preferred prey of Gadoid larvae in many areas; however, in the Irish Sea, the abundances of these Calanus species are low and highly v...

Phylogenetic analysis of the SSU rRNA gene from the piscine diplomonad Spironucleus torosus (Diplomonadida: Hexamitinae)
2016Co-Authors: Anders Jørgensen, Anders Alfjorden, Kristin Henriksen, Erik SterudAbstract:Abstract. Previous studies have recorded Spironucleus torosus Poynton et Morrison, 1990 from several species of Gadoid fishes, including the only freshwater Gadoid, the burbot Lota lota (L.). Two morphologically different isolates of S. torosus have been described (elongate and pyriform). Both have been found in saltwater, while only the elongate has been found in freshwater. To address the conspecificity of the two morphs of S. torosus, and to identify the source of S. torosus in burbot in Norway, we have sequenced the small subunit ribosomal RNA (SSU rRNA) gene from 43 isolates of S. torosus from six species of Gadoid fishes sampled at 15 localities in Norway, Sweden and the Baltic Sea. Phylogenetic analyses of the SSU rRNA gene sequence data recovered two major clades, one containing mainly isolates from burbot, while the other contained isolates from marine Gadoid fishes only. The genetic distance (based on 25 nucleotide substitutions in 789 base pairs) separating the two assemblages was not large enough to consider the two groups separate species. Spironucleus torosus isolated from burbot displayed limited genetic variation in the small subunit ribosomal RNA (SSU rRNA) gene along the post-Pleistocene migration route of its host. The pre-sent study is the first report of S. torosus in tusk Brosme brosme (Ascanius), whiting Merlangius merlangus (L.), and fourbeard rockling Enchelyopus cimbrius (L.). Four species of enteric diplomonad flagellates from Gadoid fishes in Europe have previously been described by light microscopy. Early French studies reporte
