Infection levels and species diversity of ascaridoid nematodes in Atlantic cod, Gadus morhua, are correlated with geographic area and fish size [PDF]

open access: yes, 2018
Atlantic cod (Gadus morhua) is among the most important commercial fish species on the world market. Its infection by ascaridoid nematodes has long been known, Pseudoterranova even being named cod worm.

Walleye pollock Gadus chalcogrammus Pallas, 1814 found north of Spitsbergen indicates a Pacific-Atlantic connection in the species

open access: yesFauna Norvegica, 2020
A small (36.5 cm) female walleye pollock Gadus chalcogrammus Pallas, 1814 was caught north of Spitsbergen in 2011. The specimen had a high number of pyloric caeca (n=109), indicating a Pacific origin.

New England Cod Collapse and the Climate. [PDF]

open access: yes, 2016
To improve fishery management, there is an increasing need to understand the long-term consequences of natural and anthropogenic climate variability for ecological systems. New England's iconic cod populations have been in decline for several decades and

Purification and characterisation of trypsin-like enzyme from the pyloric caeca of cod (Gadus morhua) II

open access: yesBrazilian Archives of Biology and Technology, 2001
A trypsin -like enzyme from the pyloric caeca of cod (Gadus morhua) was purified by affinity chromatography on CHOM Sepharose 4B. Some characteristics were established by its catalytic activity on T.A.M.E., typical enzyme substrate, and serine protease ...

Analysis of DNA sequence variation within marine species using Beta-coalescents [PDF]

open access: yes, 2011
We apply recently developed inference methods based on general coalescent processes to DNA sequence data obtained from various marine species. Several of these species are believed to exhibit so-called shallow gene genealogies, potentially due to extreme

Finding 16S rRNA gene-based SNPs for the genetic traceability of commercial species belonging to Gadiformes

open access: yesItalian Journal of Animal Science, 2010
A SNPs (Single Nucleotide Polymorphism) based analysis was developed to differentiate four economically important species belonging to the Gadiformes order: Pacific cod Gadus macrocephalus, Atlantic cod Gadus morhua, Haddock Melanogrammus aeglefinus and ...

Searching speeds and the energetic feasibility of an obligate whale-scavenging fish [PDF]

open access: yes, 2005
Two recently published models reach opposite conclusions on the energetic feasibility of a scavenging fish that specialises oil whale carcasses. We argue that the key difference between these models lies in their estimate of the likely searching speed of
