European colonization by the spined loach (Cobitis taenia) from Ponto‐Caspian refugia based on mitochondrial DNA variation
TLDR
The phylogeography of the spined loach, Cobitis taenia, is investigated using 1126 bp of the mitochondrial cytochrome b gene from 174 individuals collected at 47 sites, revealing a history of recent expansion and isolation by distance.

Combination of genetics and spatial modelling highlights the sensitivity of cod (Gadus morhua) population diversity in the North Sea to distributions of fishing
TLDR
A spatial model of three population units of Atlantic cod is developed to simulate population dynamics under spatial patterns of harvesting and offers a method to quantify adjustments to regional fishing mortality rates to strike a balance between maximising sustainable yield and conserving vulnerable populations.

Diversity of European spined loaches (genus Cobitis L.): an update of the geographic distribution of the Cobitis taenia hybrid complex with a description of new molecular tools for species and hybrid…
TLDR
New polymerase chain reaction restriction fragment length polymorphism markers for species determination have further been developed and applied, which would allow the unambiguous identification of parental species and their genomes in the known hybrid biotypes within the hybrid complex.

Ice age cloning – comparison of the Quaternary evolutionary histories of sexual and clonal forms of spiny loaches (Cobitis; Teleostei) using the analysis of mitochondrial DNA variation
TLDR
This work reconstructed the Quaternary historical biogeography of the sexual parental species and clonal hybrid lineages within the Europe‐wide hybrid complex of Cobitis spiny loaches and indicates the frequent origins of asexuality irrespective of the parental populations involved and the comparable dispersal potential of diploid and triploid lineages.

Conservation genomics of Atlantic salmon: SNPs associated with QTLs for adaptive traits in parr from four trans-Atlantic backcrosses
TLDR
This work adds to the evidence that much of the variation in growth rate, shape and skin pigmentation observed among Atlantic salmon parr from different natal streams is genetic.

The globalization of naval provisioning: ancient DNA and stable isotope analyses of stored cod from the wreck of the Mary Rose, AD 1545
TLDR
A comparison of ancient DNA (single-nucleotide polymorphisms) and carbon and nitrogen stable isotope evidence suggests that stored cod provisions recovered from the wreck of the Tudor warship Mary Rose had been caught in northern and transatlantic waters such as the northern North Sea and the fishing grounds of Iceland and Newfoundland.

Signatures of Selection on Growth, Shape, Parr Marks, and SNPs Among Seven Canadian Atlantic Salmon (Salmo Salar) Populations
TLDR
One SNP in a trypsin inhibitor showed a strong phylogenetic signal be- tween inner and outer Bay of Fundy that was correlated with the slower growth rates, deeper bodies, and longer pectoral fins of parr from inner Bay rivers and may represent convergent local genetic adaptation.

Cytogenetic characteristics of the fish genus Cobitis from England.
TLDR
The chromosomes of spiny loach specimens, genus Cobitis, from three populations in England were examined using Giemsa staining, Ag-NOR, C-banding and CMA3 techniques and revealed that only C. taenia occurred in the northern part of the Cobitis distribution range.

Substratum preferences and diel activity patterns of spined loach Cobitis taenia in England: implications for conservation management.
The substratum preferences of spined loach from eastern England differed significantly between fish of different age groups, sexes, habitat origin (river or drainage ditches) and even between…
