Ascaridoid nematode infection in haddock ( Melanogrammus aeglefinus ) and whiting ( Merlangius merlangus ) in Northeast Atlantic waters

The complete mitochondrial genome of the whiting, Merlangius merlangus and the haddock, Melanogrammus aeglefinus: a detailed genomic comparison among closely related species of the Gadidae family.

We determined the first complete mitochondrial DNA (mtDNA) sequences for the whiting (Merlangius merlangus, family Gadidae, order Gadiformes) and the haddock (Melanogrammus aeglefinus, family Gadidae, order Gadiformes). The entire mitogenomes were amplified and sequenced by primer walking using newly designed specific internal primers. Lengths were 16,569 and 16,585 bases for whiting and haddoc...

A trans-Atlantic examination of haddock Melanogrammus aeglefinus food habits.

The food habits of Melanogrammus aeglefinus were explored and contrasted across multiple north-eastern and north-western Atlantic Ocean ecosystems, using databases that span multiple decades. The results show that among all ecosystems, echinoderms are a consistent part of M. aeglefinus diet, but patterns emerge regarding where and when M. aeglefinus primarily eat fishes v. echinoderms. Melanogr...

In vivo red blood cell sickling and mechanism of recovery in whiting, Merlangius merlangus.

Haemoglobin concentrations in vertebrate red blood cells are so high that in human sickle cell disease a single surface amino acid mutation can result in formation of large insoluble haemoglobin aggregates at low oxygen levels, causing peculiar cell deformations or 'sickling'. This may cause vascular occlusion and thereby severe pain, organ failure and death. Here, using light and transmission ...

DNA damage in dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) from European seas.

Dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) were collected from coastal and offshore locations in the Baltic (dab only), North Sea (haddock from one location only) and Iceland. Blood was analysed for DNA strand breaks using the comet assay and liver samples for DNA adduct concentrations. DNA strand breaks were at background levels in dab from the two Iceland locations and from ...
